TQCSHEEN PG1000 PGX+ POCKET GONIOMETER
The PGX Dosing Unit is optionally available. This add-on pumping device is designed to deliver liquid droplets from a disposable one ml syringe. The PGX Dosing Unit is used as an add-on to the PGX+ to provide more accurate delivery of droplets or allow for the use of high viscose samples.
The PG Dosing Unit offers different pump modes.Some of these will pump out a fixed, preset droplet volume whereas other modes are programmable by the operator. Some of the programmable modes are based on a pump cycle where the pump will reverse automatically to offer measurements of wetting hysteresis using the advancing/receding contact angle method. The list below describes the available operating modes:
