Aerosol contamination risk reduced by CPs

Bioscience has developed the Gilson Microman, a fully adjustable positive displacement pipette that uses disposable capillary pistons (CPs) to ensure accurate, rapid, safe and contamination-free pipetting, whatever the sample type.

It has been designed to combat the problems in aerosol contamination that arise when using air displacement pipettes for viscous, volatile, corrosive or hazardous liquids.

Pipette shafts are a common source of contamination attributable to aerosols formed during aspiration. The syringe-style Microman CPs eliminate the air space between the pipette body and the sample, thus protecting it against contamination and any trace carryover. Sample integrity is also safeguarded - essential for critical procedures such as PCR, forensics, cancer diagnostics and genetic disease testing.

With no elastic air space to expand or contract, the aspiration force remains constant, unaffected by the physical properties of the sample. This means that even very viscous or high-density liquids can be pipetted easily and precisely.

Available in the UK from Anachem, the Gilson Microman comes in six models, from M10 (1-10µl) up to M1000 (200-1000µl), is lightweight (50g) and is suitable for both right- and left-handed users. All models feature easy volume setting with one hand using the push button.

The device requires minimal maintenance as there is no need to recalibrate it when the piston capillary is changed.
