supply: amazon It has a different design than a standard micropipette. These pipettes enable the operator to aspirate the liquid only once and afterwards dispense equal volumes into different vessels regularly.
Lesser pipettes can do the job with scaled-down quantities, though larger sized capacities also are accessible for a lot more voluminous supplies.
The quantity of liquid that may be transferred employing a multi-channel pipette is typically adjustable, and is usually established by rotating the plunger to the desired volume marking to the barrel.
