The Laboratory Positive Displacement Pipettes category includes the instruments, accessories and consumables needed to measure, dispense, aspirate, pump and route liquids accurately between vessels, instruments and process steps. Selecting them as part of a complete workflow helps prevent compatibility problems that are easy to miss when individual items are considered separately.
Volume error, unsuitable wetted materials, trapped air and poor connections can affect concentration, recovery and repeatability. This is why laboratories should assess liquid viscosity and chemistry, wetted materials, connection size, and manual or automated control before choosing a product, rather than relying only on capacity, appearance or headline specifications.
The complete fluid path should match the required volume or flow range, liquid properties, tubing and connection sizes, control method and cleaning approach. Looking at the full sequence makes it easier to identify the correct accessories and consumables before the equipment is put into service in analytical, life-science, chemistry, process-development and quality-control laboratories. As part of the Laboratory Liquid Handling Equipment range, these products can be selected with the equipment and consumables used before and after this stage.
Our Laboratory Positive Displacement Pipettes range
Our collection covers the tips for these pipettes the same as standard pipette tips, operating principle of positive displacement pipette differ from a standard pipette, when to use a gilson microman instead of a regular pipettor, and these for macro-volume transfers, giving laboratories practical choices for routine work and more specialised applications.
The tips for these pipettes the same as standard pipette tips
Positive displacement pipettes require specialised capillary/piston sets that are designed to fit the specific mechanical linkage of the pipettor. For routine and specialised work, assess liquid viscosity and chemistry, wetted materials, and connection size. Matching these points early helps avoid adapters, consumables or operating limitations being discovered after purchase. Within the wider method, these products help laboratories move liquids with the control and compatibility needed from initial preparation through final dispensing. They should be reviewed together with associated consumables, accessories and cleaning requirements.
Operating principle of positive displacement pipette differ from a standard pipette
Unlike standard air-displacement pipettes that use an air cushion, positive displacement models use a piston that comes into direct contact with the liquid, ensuring that the volume dispensed is unaffected by the liquid's density or viscosity. When comparing options, consider wetted materials, connection size, and manual or automated control. The correct choice should fit the sample, expected workload and any equipment already used in the method. Within the wider method, these products help laboratories move liquids with the control and compatibility needed from initial preparation through final dispensing. They should be reviewed together with associated consumables, accessories and cleaning requirements.
When to use a GILSON Microman instead of a regular pipettor
The Microman is essential when working with viscous liquids (like glycerol), volatile solvents (like ethanol), or samples where aerosol contamination must be completely eliminated. Before ordering, compare connection size, manual or automated control, and volume or flow range. A product that fits the complete workflow will generally be easier to validate, maintain and reorder. This is especially valuable when teams need to move liquids with the control and compatibility needed from initial preparation through final dispensing. Consistent handling also reduces the risk of variation between batches or operators.
These for macro-volume transfers
The BRAND Transferpettor Digital series is specifically designed for high-accuracy transfers of large volumes, with capacities reaching up to 10 mL. Before ordering, compare manual or automated control, volume or flow range, and accuracy and precision. A product that fits the complete workflow will generally be easier to validate, maintain and reorder. This is especially valuable when teams need to move liquids with the control and compatibility needed from initial preparation through final dispensing. Consistent handling also reduces the risk of variation between batches or operators.
Featured brands
BRAND is represented in options relating to these for macro-volume transfers, Gilson is represented in options relating to when to use a GILSON Microman instead of a regular pipettor, VITLAB is known for plastic labware, dispensing products and chemical-resistant handling solutions, and LLG Labware is known for practical laboratory consumables, accessories and routine bench supplies. Compare each BRAND by liquid viscosity and chemistry, wetted materials, connection size, and manual or automated control, and check what is included with the product so the complete setup is clear before ordering.
