Part number
Theta 50 is unit with two pump pistons connected in parallel. Flow-rates range is from 0.1 to 50 ml/min. and maximum operating pressure of 30 MPa (4351 PSI).
It is suited for preparative and flash applications in liquid chromatography but also for solvent pressurizing by samples extractions, etc. Beneficiary is also a very stable run even at low flow rates.
This pump is designed as OEM / built-in unit.
There is a possibility to use this pumps even at high pressure gradient mode, where two, three or four units controlled from PC using RS232 or voltage.
Control board is mounted at the unit back side, therefore the installation is very easy. Only connect power voltage and RS232 and pump is ready to work.
When working with buffered solvents, it is possible to use pistons back washing.
Pumps are supported with software ECOMAC and Clarity.
THETA PUMP isn't equipped with pressure sensor.
