Accuracy refers to the skill of the pipette to provide the quantity of liquid that it's calibrated to provide. This is usually said as an precision vary, such as ±0.one mL.
bear in mind that temperature, atmospheric tension, and liquid viscosity and density can noticeably impact this pipette's efficiency.
An economical solution that gives precision and accuracy for plan programs further than sector specifications
Bluetooth® relationship permits interaction with TRACKMAN Connected, permitting for sample tracking and digital reporting just after your workflow is total
totally depress the plunger right until it stops at more info the next stop level to deposit the liquid into the right tube.
