We think it is safe to say that we have all struggled to avoid contamination in our labs and within our experiments and processes… Well, we need struggle no longer because a hero is in our midst — the Clean Air Filtration System.
With its presence on the front line of our defense in the battle against unruly particles like dust, we can feel safe in the knowledge that particle contamination will be a thing of the past. Clean air and optimal testing and production conditions will prevail!
The HEPA flow-through air filtration system eliminates particles in air, e.g. dust. This is excellent news, because unwelcome particles in the air within a closed testing environment can be a critical contamination source in non-contact liquid handling, e.g. during the production of biochips.
A large HEPA filter is used as the last filter element, and the HEPA is usually combined with an enclosed M2 automation solution.
If you need a tight control loop between the temperature, humidity, cooling and dew point of system components, this first-class climate control software module from M2-Automation is the best option.
It is designed it to help you to control the variables by taking care of set points on your behalf. Additionally, it saves time stamped climate data in an Excel-readable format, making results easy to access, without the need for additional special software.
It gives you the control that you need, therefore, improving your process by allowing you to bypass potential problematic environmental reactions that could affect your data results. For example, the unique humidity overshot control guarantees a very constant level of humidity, which combats the formation of relatively large microdroplets that are usually generated by nebulizer operating systems.
The ultra-small proprietary M2 humidity and temperature sensor reads the current conditions and is source for a perfect control.

In non-contact liquid handling, small air bubbles generated by spontaneous degassing of dissolved gases in liquids can cause all kinds of negative effects, e.g. distortions of the liquid flight path, random volume errors or, at worst, complete loss of function.
However, online degassing prevents such problems, which is one of the reasons that M2’s Online Degasser is such a popular optional component in all of our non-contact liquid handling solutions. Aside from being totally effective in degassing, it’s also easy to use and built to last.
Online degassers are used for online removal of dissolved gases (usually, air) from liquids.
If an air bubble were to migrate into the chamber of a piezo driven microdispenser, it could cause complete loss of function, but with our Online Degasser, this can be avoided if the system liquid is degassed online right after it has left the storage bottle or vial.
Is air bubble formation causing problems in your dispensing process? If so, the Liquid Path Air-free is your solution. Developed by M2 to make your life easier, it’s an effective means of avoiding problems caused by spontaneous degassing of dissolved air.
Therefore, it improves the overall process and reliability of low volume non-contact liquid handling in the picoliter- and nanoliter-volume range.
Liquid Path Air-free option includes all tubing, ferrules and special fittings for upgrading your microarray printer with this excellent feature.
The Safety Housing for the microarray spotter product line. This safe environmental enclosure accommodates the robot X,Y,Z-stage system, and is able to house all of the additional components that are available with the microarrayer instrument, as well as a microdispense controller.
The enclosure provides the safe environment needed to achieve uncontaminated, reliable results. The design reflects the many years of experience and understanding of necessary environmental conditions for accurate testing, which M2-Automation has perfected over the last decade of its automation solution development history.
M2-Automation provides a wide range of source adapters. Mirowell plates, reagent troughs of any format and custom tailored shapes are supported by our instrument series. Also, holder with flow through cooling option for small vials, tubes and multi-well strips that fits into the source vial positions of the M2 microarraying spotter range. For cooling the holder must be connected with a cryostat.
M2 standard target holder has the footprint of an MTP following the ANSI standard. Glass slides are easy to insert and are gently hold in a defined position by a spring loaded lever. Repeatable placing accuracy guaranteed.
The holder tolerates little deviations in the dimensions of the slides and accepts both formats: 75x25 mm and 3x1 inch. For regulated heating, the M2 heat controller can be connected to an adapter (holder) with integrated temperature sensor and heating element that accommodates up to four glass or plastic slides.
Also, vacuum target plates with custom dimensions including optional cooling and heating functionality are supported by M2's spotter robot series. Just ask the M2 team for your matching target tray.
The Syringe Pump from M2-Automation is a multifunctional tool that is built to guarantee accurate and thorough performance, whilst maintaining simplicity of process. It is linear, motor driven and chemically inert, with a 3-channel ceramic valve and an integrated bypass function. The inlet and outlet ports are directly connected and the default syringe volume is 100microliter, with a resolution of 0.1microliter.
The main functions of the M2 Syringe Pump is: the aspiration and dispensing of sample liquids or cleaning and coating reagents; the washing of the dispenser tip; and the resuspension of sample sediments, living cells and other particles.
Another extremely useful feature of this product is that the valve position of the syringe pump can be used to block the flow path to the system liquid bottle, e.g. when no microdispenser is installed due to exchange or maintenance, or when a piezo driven microdispenser is treated with coating solution and no liquid is flowing into the dispenser. To utilize this feature, one must simply connect the syringe to the outlet port of the valve.
M2’s Ionizer is a device for the removal of electrostatic charges. Such charges can generate strong local electrical fields while residing on non-conductive surfaces such as MTPs, plastic slides and Lab on a Chip devices.
With plastic substrates and MTPs in particular, electrostatic charges can completely ruin the dispensing (spotting) results, but you can rely on M2’s Ionizer to prevent this by neutralizing the charges, allowing your dispensing process to run smoothly and accurately.
Also, in many non-contact liquid handling applications, the ejected droplets can become electrostatically charged. If they are very small, as is the case with Piezo dispensers, this means that the local charges can significantly change the flight path of the droplets, with the consequence that they are no longer able to reach their target position. But, once again, the Ionizer prevents this problem, ensuring an unhindered flight path for the droplets.
Note: The ions produced are harmless for humans. Healthy air contains many ionized air molecules.
Sealing the wells of an MTP is an efficient means to prevent solvent loss by evaporation or sublimation during storage, but when a well needs to be opened efficiently and safely, without other wells being affected, a piercer is needed.
The Piercer from M2-Automation is a tool for just that purpose. It can automatically pierce the sealing foil of individual wells, allowing access to their contents while all unpierced wells remain sealed.
The piercing of the MTPs is performed by a conically shaped stainless steel tip positioned above the well, and then moved downward until it has penetrated the sealing foil, just before sample uptake.
A piercer enables on-demand access to any sealed well, which can be very useful when, for example, aspirating only part of the content for a planned dispensing program.
Note: The Piercer package includes a head-mounted piercing tool and a motor driven axis that moves it up and down via motor controller.
Wash procedures are a standard part of every experiment and are implemented between the dispensing of every sample. Throughout such a procedure, flexibility is key, and that is a feature we guarantee with the wash station and its components.
One example of this flexibility is the user-defined procedures that allow you to create sample-specific wash procedures to ensure that cross-contamination is never a problem. Another example is the multiple options for wash solutions that allow you to tailor the wash to your specific project needs.
You can be sure that your experiments are always efficient and contamination free when you use M2’s wash station. It is yet another product that we have designed with the ease and efficiency of your experimentations in mind.
The wash station comprises all hardware components necessary for the implementation and operation of a wash station. A pump unit is not included due to the fact that we have a number of pump unit options, giving you the choice of how you would like to tailor this element of the overall solution to your specific needs. The station itself is mounted on the base plate of the instrument and includes a supply line for the washing liquid, a wasteline, all necessary tubing, containers and connectors. We’ve even created the Chemical Compatibility Manual, which is available upon request to help you choose the safest and most effective wash solution for your specific experiment.
The wash station is built for the external washing of an installed microdispenser tip during an automated liquid handling program (wash run). In addition, the wash station provides the perfect environment for manual or automated strobe light supported inspection and tuning of the droplet generation (ejection) process.
The Imaging Basic from M2-Automation is a 2D imaging hardware tool for non-contact liquid handling within the picolitre (pL) and nanolitre (nL) volume ranges. Although the system is a more basic version of our advanced imaging system, it is still a first-class piece of hardware.
The supporting imaging software provides automatic quality control of the microdroplet ejection process during a spotting run. This process is typically performed after each sample aspiration step.
The 2D Droplet Detection software module is designed to monitor and analyse droplet formation before and after spotting. This is an invaluable function when it’s necessary to establish optimal dispensing parameters for each and every sample on a fully automated run.
Specific actions can be triggered if there is a failure of function, e.g. when no droplet is detected, when there is a deviation in the determined droplet volume and/or flight velocity, or when the flight path falls outside acceptance limits specified by the user.

The 3D Droplet Detection soft module from M2 is the big brother of the 2D Imaging System. Its purpose and functions mirror those of the 2D but with one significant difference, which is an additional droplet camera that enables 3D data gathering.
3D improves real time droplet flight path detection by offering a forecast of the droplet hit point coordinates. This forecast can be applied for an XY coordinate correction of the target substrate and, therefore, results in accurate sample deposition and perfect feature alignment. With this software module, bad feature alignment and crooked microarrays will become a thing of the past.
3DDD (3DimensionalDropletDetection) is a software module for the microarray instrument control software that enables automatic 3D optical detection of droplet ejection. Also, it enables analysis of droplet volume, velocity and flight path in X and Y directions during a spotting run.
The Micro Dispense Controller (MDC) is a controller that is compatible for use with all microdispensers offered by M2-Automation, and the package also includes all necessary electronic and pneumatic components.
If you would like to increase the efficiency and accuracy of your project, it makes sense to use hardware that you can rely on to perform flawlessly. That’s why you need M2-Automation’s MDC; it’s the perfect fit for your microarray spotter hardware needs.
The MDC is used to control M2-Austomation’s non-contact liquid handling solutions across all of our product lines. It provides accurate regulation and adjustment of pressure supply, precise generation and amplification of signals, and it includes electrical input and output ports for the use of external hardware. The current microdispense controller version includes also the control PC - a very space saving feature.
Here at M2, we have designed and built two excellent pneumatic units. The positive pressure version is the first of those, and it’s a product that will improve the levels of precision and flexibility within your processes.
This adjustable and regulated positive pressure supply unit can provide a positive pressure of up to 1000 mbar, which can be regulated down to +/- 1mbar (adjustable hysteresis). The pressure is adjustable from 10-1000mbar and, for your convenience, the pressure level is displayed on the front side of the device, while the pneumatic and electronic connections are located on the rear side.
The important features that both this model and the negative pressure version share are that they both include a pump, a pressure pilot valve, a pressure sensor and electronic components for precise pressure regulation.
Using the pressure unit, you can manage the generation and precise regulation of a positive pressure difference in a chamber, bottle or vial. A typical application of this device would be the provision of a constant driving force for liquid transportation in non-contact liquid handling. A must have for the nanoliter microdispenser product range.
A dual channel pump unit. It includes two membrane pumps, a smaller and a larger one. The flow rate of both pumps is adjustable by internal potentiometers. The liquid and electronic connection ports are located on the rear side. The activity of the pump is indicated by a blue status LED on the front side.
The pump unit is able to transport two liquids at the same time, e.g. for the supply and the waste line of a wash station.
At M2-Automation, we offer a number of heating devices to service the needs of your project, and in order to enhance their value and accuracy, we have designed a temperature controller. It is an electronic controller for heating devices offered by M2 that contain one or more temperature sensors, and one or more heating elements.
The M2 Temperature Controller heats up target substrate holders such as slides, TXRF sample discs and micro-dispensers. It reads the current temperature and turns the heating element on or off accordingly, allowing the set target temperature to be reached and maintained, with a maximum deviation of less than 0.5°C. The employed regulation algorithm has been optimized for this task and can be calibrated for each heatable device.
An electronic interface that detects electrical either TTL or short cut input signals (which signal is set by a jumper) send from an instrument or device.
Detection of the corresponding input signal generates a 24 V output signal that can be used to trigger action of a second or more instruments or devices. In short, the coupler is an electrical low level communication interface supported by many laboratory instruments (e.g., HPLC systems).
The coupler can be used for many different tasks, wherever it is required to trigger an action (microdroplet ejection or microarray print start) by a simple shortcut or TTL signal sent by an external master device.
You got the power! Well, you will have it when you invest in M2’s power distributer. Experiments can be tricky, and often require quite a bit of equipment, which is why we designed the power distributer to streamline your power supply set-up and to save on space.
It has one switchable 24 V DC input and four switchable 24 V DC output ports, which are all located at the rear side. The status of each port (on or off) is indicated by a blue LED on the front side.
The power socket unit is most useful when between two and four additional devices require 24 V DC power supply. Therefore, instead of supplying each device with a separate power supply, the power of one 24 V DC supply can be distributed between four devices. Simple.
