Pipetting is a finely-controlled process that requires very specific control of the pipette plunger - and consequently the piston - to aspirate and dispense accurate volumes. The Accupet Evo Pipette specifically improves on this process by introducing a magnetically assisted plunger and piston. The assisted motion allows the user to be much more careful and precise with their pipetting motion. A stiffer piston makes it more difficult to pipette precisely and may yield inconsistent results. The Accupet Evo Pipette is specifically engineered to improve consistency and accuracy.Besides improving precision and accuracy, the Accupet Evo Pipette makes it incredibly easy and comfortable to add high-performance pipetting to any lab. The materials for the pipette body, tip ejector, and tip cones are specifically chosen to be durable and withstand the laboratory elements. Furthermore, the Accupet Evo Pipette is universal tip compatible, so that users can easily bring it into their lab with minimal compatibility issues. Especially in labs that work with delicate samples, contamination can be a huge factor, so the Accupet Evo Pipette is fully autoclavable to help avoid contaminants. This pipette is designed so that almost anyone, anywhere, can comfortably, confidently, and reliably use this pipette toFeatures:Magnetically Assisted Piston for Consistent ResultsOne of the Lowest Plunger Forces on the Market!Corrosion Resistant Tip EjectorUnique Shock Absorbing Tip Ejector for Enhanced DurabilityHighly Durable PVDF Spring-Loaded Tip ConesVolume Lock Mechanism to Prevent Volume DriftFully AutoclavableUniversal Tip CompatibilitySingle-Channel, 8-Channel, and 12-Channel ConfigurationsColor-Coded by Volume Range for Easy IdentificationLarge and Clear 4-Digit DisplayErgonomic Design.
