Lab, Pilot and Production Scale HPLC
The HPLC solvent pump
Developed as solvent pumps for preparative chromatography, "K series" are perfect as pumps for preparative HPLC. Dual plungers and a high precision servo motor allow highly accurate pumping with minimized pulsation.
Key features include:
- A wide range of flow rate: the minimum flow rate is precisely 1/1000 of the maximum.
- Gradient operation: Adding on the sub-pump enables standalone gradient operation.
- Recycle compatibility: The dead volume is extremely low so that the recycle characteristics are outstanding.
- Self wash (optional): Cleaning fluid is pumped through the plunger wash ports to provide cleaning of corrosive substances such as salts.
- Explosion proof (optional): Explosion-proof pumps are also available.
- High flow: Flow rates of 3L, 5L and over 10L/min are also available .

Auto-injector
An easy to use automated syringe type injector! A practical alternative to injection using piston pumps.
Key features include:
- Excellent for repetitive stacking of injections.
- Operation is controlled by internal computer.
- 10mL or 5mL syringes can be used.
- Remote control may be conducted from external equipment.
- The syringe does not contact the sample so that cleaning is unnecessary.
