Delivering high precision for

time-pressure microlitre dosing

Laboratory equipment and analysis devices used in the life science as well as
pharmaceutical sectors require very accurate and repeatable dosing components.
Bürkert’s Type 8763 Pressure Controller achieves high precision dosing of microlitre
volumes and a response time in milliseconds, saving time and money. Bürkert’s Tony
Brennan looks at how this can help OEMs reduce their time to market
