With kind regards to Tecan Männedorf, I write this post about the

HP D300 Digital Dispenser

This device was manufactured within a cooperation between Tecan and Hewlett Packard and is a new kind of technology. Dispensing Liquid in very small volume ranges, combined with high-precision is the final product of this companies. The outcome of this project is a completely maintenance free device with cartridges you know from various inkjet printers. A very interesting solution you definitely should look into.

Copy from Tecan Landing Page:

The HP D300 Digital Dispenser offers a simple method to generate dose response curves which eliminates serial dilution by offering picoliter to microliter non-contact dispensing of drug candidates directly into your assay plate. From small molecules in DMSO to biomolecules in surfactant-containing aqueous solutions, the HP D300 delivers high quality, low volume dispensing.

Using HP’s Direct Digital Dispensing technology, this convenient benchtop solution requires almost no set up time and single use T8+ and D4+ Dispenseheads virtually eliminate the risk of cross-contamination. Backfilling can also be carried out easily and accurately. It allows rapid delivery of any dose to any well, saving time, minimizing waste of valuable samples and accelerating drug discovery.
