Description
The Semi-PRE HPLC system can fulfill most analysis and preparation requirements. The High pressure preparation HPLC system ts mainly used in small-scale sample preparation and purification in laboratories.
- The new upgraded pump reserves the classic reciprocating parallel pump design to provide accurate flow and minimize pressure fluctuations.
- The structure of one-piece check valve is simple and provides excellent leak resistance.
- The piston rod can be retracted automatically so you to replace the piston seal easily without opening the instrument case.
- New piston rinse function adopts dual-piston seals design, it is provided for buffer salt systems.
- Less noise and higher reliability.
- Extended warranty service and more comprehensive after-sales service to assist with your analysis.
- Specifications of Infusion Unit.
