Biotech Systec ZHCR (Zero Hysteresis / Constant Run) Degassing Dual Stage (DST) Vacuum Pump, Preparative, Side Mounted
Product Number: 9000-1897
Replaces Product Number: 9000-1718
The DST Pump with PCB is a vacuum control system for use with degassing chambers. The system includes a dual stage (DST) vacuum pump and a Smart board controller to maintain vacuum levels. There is a connector for optional external LED indicators or error outputs. The prep versions are designed to handle high vapor loads from high flow rate chambers or fluids with low vapor pressure that will cause increased solvent pervaporation through the membrane.

PUMP CONTROL SPECIFICATIONS:
Power Requirements | 24 VDC @ 0.75 Amp max. (< 5 Watts consumption average) | |
Temperature | 50 o C or lower when run in ambient conditions (20- 25 o C) | |
Vacuum Sensor Calibration Accuracy | Prep 80 mmHg +/- 5 mmHg Analytical 50 mmHg +/- 5 mmHg | |
Closed-Loop Control Setpoint | 50 mm Hg absolute (analytical) or 80mm Hg (prep) pump runs at high RPM until near setpoint, then speed is varied to maintain a value of setpoint— load independent. | |
Errors Detected | 1 – Pumpdown: | Prep — Unable to reach 82 mm Hg in 10 minutes. Analytical — Unable to reach 52mm Hg in 10 minutes. |
2 – High Vacuum: | Prep — Vacuum > 110 mmHg for more than 6 min. in the running state (after pumpdown). Analytical — Vacuum > 82 mmHg for more than 6 min. in the running state (after pumpdown). | |
3 – Sensor Signal: | Sensor Failure Detected Sensor signal >800 mm Hg or sensor signal <10 mm Hg. | |
