Low-volume Dispensing

When it comes to achieving consistently excellent dispensing results, overcoming challenges is par for the course. But, when all of the factors and elements involved are considered, organised, controlled and contained within an optimal environment and under optimum conditions, the outcomes can be staggering.


The key elements of low-volume dispensing are the target substrate upon which the samples or liquids are dispensed, the samples or liquids themselves and how they are transferred from the source onto the target. These three elements are something that we at M2-Automation understand exceedingly well. Our team has a deep knowledge of how those elements need to interact in order to attain perfectly accurate results, in the most efficient way possible.

Microdispensing Technology

One of M2-Automation's core technologies, and part of every Microarray-Spotter setup, is our microdispensing technology. Providing a volume range from picoliter to microliter, it's suited to a variety of applications. Our contact and non-contact dispensers are capable of handling tiny volumes of the most sensitive or very expensive samples, including solutions of all kinds of biomolecules or chemical reagents, and even suspensions of living cells and small, solid particles.

All M2-Automation Instruments support all three microdispensers. Also, switching from one to the other is simple, and it does not require any tools. So there’s no need to buy a second instrument when working with picoliter, nanoliter and low-microliter volumes.

COO of Macro Array Diagnostics GmbH, Austria

I can only recommend M2-Automation and their microarray printers.  The M2 devices are of remarkable quality, precision and reliability. Working with the M2 team was great! They were always willing to consider our ideas and help us implement new components to improve automation. If we needed a microarray printer, we would always choose M2-Automation.

Dr. Johannes Wöhrle
CTO of BioCopy GmbH, Germany

Looking for a high-precision and continuous-mode spotter, we found the most comprehensive partner for our needs in M2-Automation GmbH and their iONE-1200. Since we have over two decades of experience using different spotting systems, we absolutely can recommend M2-Automation’s instruments and its team for a successful partnership.

Humanbiocare (HBC) SRL and Unimore, Italy

Thanks to M2-Automation GmbH and their iTWO-300P microdispensing instrument, we were able to handle the overwhelming increase of requests during the still-ongoing pandemic.  Within a couple of weeks, we planned and implemented the integration of the iTWO into our routine production cycles and, as a result, our output numbers were significantly multiplied. 

The robust and steady workflow we were able to achieve allowed us to deliver uniform products in good time.  Thanks to the excellent technical support provided by the M2-Automation team, we were able to adapt, modify and adjust the system to match our individual needs.  The contribution from M2 was the key element in the process we underwent in order to lift our production to the next level, which enabled us to satisfy our customer needs to a much greater degree.

The quality, flexibility, wide volume range and ease of software use was our main priority when we chose M2-Automation dispensing technology. The outstanding application and after-sales support show the attitude of the M2 team's commitment. After experiencing other dispensing technologies, M2-Automation technology is the right choice for our research work.

Mr. Dr. Peter Miethe
CEO fzmb GmbH Bad-Langensalza, Germany


The instrument (iTWO-400) was built according to our application requirements after constructive discussions with M2-Automation. Hands on training by M2-Automation specialists was organised at commissioning and after a few months of operation, which was very useful to quickly acquire the necessary skills. The service is impeccable: quick answer to all our questions and suitable suggestions. Ten years later, we are still very happy that we bought our M2 instrument!

Prof. Dr. Ronnie Willaert
Vrije Universiteit Brussels, Belgium

Martin Müller and his entire team at M2-Automation have supported us with excellent solutions during the initial setup of our first production prototypes, all the way long to the implementation of a robust and efficient production facility with minimal maintenance demands. In the initial phase of our collaboration, we benefited most from their enthusiastic passion to identify our specific requirements and the best compromise between perfect technical solutions and a reasonable budget to reach the targets.  Over the last years, with a constant production running, their reliable and incredible support, as well as their creative solutions to bridge the sometimes unavoidable waiting times for spare parts, has been of highest value for our company. If we could put "stars" here for professionalism, reliability, technical excellence, and last but not least, a trustful collaboration, it would be 5 of 5 stars and a clear recommendation. M2-Automation GmbH – please carry on like this!
