ML500 Pump Configurations

A simple touch of the hand probe button or a tap of the foot switch actuates the precision syringe drives to fill or dispense a desired volume of fluid. MICROLAB 500 diluters and dispensers are precision fluid measuring instruments based on Hamilton's world-renowned syringe technology. The semi-automated instruments use positive displacement to achieve highly accurate and precise fluid aspirations and dispenses.


Single Syringe Dispenser


The Single Syringe Dispenser has one syringe drive and one valve positioner. This pump is designed for applications that require one fluid path and dispensing volumes within the programmable resolution of the ML500 syringe drive. The single syringe dispenser can fit syringes from 25 µL to 25 mL. For the greatest accuracy and precision it is recommended to operate syringes above 10% of their nominal volume (for example 2.5 µL from a 25 µL syringe). If lower volumes are desired the ML500 is capable of dispenses down to 0.1% of nominal syringe volume with a modest decrease in accuracy and precision.

Dual Syringe Diluter


The Dual Syringe Diluter has two syringe drives and one valve positioner. This pump is designed for applications that require the dilution of several unique samples with the same diluent. Common applications include Blood Alcohol Analysis, Sample Prep for HPLC, GC, ICP, AA, Liquid Scintillation and other analytical devices, and Scheduled Oil Sampling (SOS).

Dual Syringe Liquid Handler


The Dual Syringe Liquid Handler has two syringe drives and two valve positioners. This pump is designed for labs that require ultimate flexibility from their equipment. Configurable valve and syringe mounts enable attachment of all ML500 and PSD/2 valves. A quick change of the valves and syringes converts the Liquid Handler from diluting to dispensing and much more.
The Hamilton MICROLAB 500 Syringe Pumps are available in 4 different syringe and valve drive configurations.  Each instrument is design around Hamilton Companies tried and true precision syringe pump technology to deliver superior performance.
