Created as part of an agreement with Hewlett-Packard, the HP D300 digital dispenser is a standalone instrument which uses HP Direct Digital Dispensing technology to deliver picoliter to microliter volumes of drug compounds. This device can reduce titration times from hours or days to minutes. It features HP D300 T8 cassettes that dispense doses from 13 pL up to 5 µL directly into bioassay plates using HP’s inkjet technology; its single-use dispenseheads can reduce cross-contamination.
