More about the iTWO™-200

The instrumentTWO-200 from the iTWO™ series is an entry-level microarray dispensing instrument built for a broad spectrum of applications, making spotting on a high variety of targets possible.

The iTWO™-200 is available with Triple-Jet technology, which combines three different micro-dispensing technologies in one instrument. These are:

  • The Piezo Driven Micro-Dispenser (PDMD) for ultra-low pL up to nL applications
  • The Solenoid Valve Driven Micro-Dispenser (SDMD) for nL up to mL applications
  • The new M2-Dispenser (M2MD) with a shockwave generator and a modulator with a broad range of available dispensing tips made from glass, stainless steel or disposable plastic tips for avoiding carry-over.

All M2MDs can be equipped with a cartridge vessel for bulk dispensing, a degasser and temperature control for maximum reproducibility and high volume accuracy.

instrumentTWO-200 is controlled by easy-to-use software with real-time droplet imaging and drop observation. The software is largely image-based and reflects the instrument layout, providing a self-explanatory systematic workflow for creating custom-specific experiments. Password protected user profiles can be created to separate the workflow of multiple users.
