Pipets, Pipettes, Syringes, and Needles

Accurate liquid measurements, dilutions, and transfer is key to most successful laboratory assays and analyses. Find the right liquid handling tools for your specific assays and needs.

Pipets

Pipets are used to aspirate and dispense larger and specific amounts of liquid. They made be reusable or disposable, made from glass or plastic (typically polystyrene), nonsterile, sterile, or autoclavable, and cotton-plugged or plain.

Serological pipets: Graduated to measure and dispense a range of liquid volumes
Volumetric pipets: Calibrated to contain and dispense a single fixed volume
Transfer pipets: Typically used to deliver unmeasured amounts of liquids

Pipet Fillers

Pipet fillers or controllers help to more easily and rapidly fill and dispense liquids from pipets.

Manual pipet fillers
- Application-specific bulbs for Westergren and other specific methods
- Plain and safety bulbs with vacuum, aspirate, and dispense valves
- Pipet pumps that offer one-handed operation
Electronic pipet fillers
- Battery-operated and rechargeable for portability and flexibility
- Electrically powered for use in hoods or on benchtops

Pipettes
