ALPHA 50 PUMP With flow rate 0.05 – 50 ml/min and limit of
pressure 30 MPa is this pump suited for semipreparative applications in
liquid chromatography. Thanks its very stable run at low flow rates is
it possible to use the pump also for analytical applications. It is
designed with two pump heads connected in parallel with piston diameter
of 3/8”.
Quite new concept of electronic controlling, pump drive,
shape of cams and pressure transducer expand its functions and improve
its reliability against previous type LCD 4020.7. Intuitive operating using simple keypad allow easy chose functions as follow: - flow rate
- maximal flow rate- PURGE ( for priming and washing)
- low pressure limit
- high pressure limit
- pulsation compensation on-off
- pressure unit (PSI, MPa or bar)
- control mode ( by keypad, RS232 or using voltage)
- display brightness
Two LED displays allows to watch (also from a distance) adjusted flow
rate and operating pressure. By pump function choosing, give you this
displays enough of information for adjusting.
There is
possibility to use this pump by high pressure gradient mode, where are
two, tree or four unit controlled from PC using RS232 or voltage.
By work with buffered solvents is possible to use pistons back washing.
