The Differences Between Single Channel and Multi Channel Pipettes

Maria J. Eubank August 22, 2022

One of the staple tools that are ever present and common in laboratories is the pipette. Pipettes are small tools that are especially calibrated plastic tubes or transparent glass. Pipettes are used to hold a measured volume of liquid samples. They are also used to transfer the liquid samples from one container to another.

Pipettes are considered a staple in research laboratories and certain industries like medicine, biology, and chemistry. There are two types of pipettes—single channel pipettes and multi channel pipettes. Single channel pipettes are non disposable instruments that typically have an air displacement design.

The air displacement design enables the pipette to produce precise measurement results using one disposable tip. On the other hand, the technique and technology behind the multi channel variety is similar to that of a single channel pipette but it takes more than one tip.

Single channel pipettes and multi channel pipettes share a lot of similar features. For instance:

  • Volume setting (using a single hand)
  • Exchangeable volume control knob
  • Levered ejector arm (for quick releases of tips)
  • Ergonomic finger hook
  • Curved ejector bar (for reduced ejection force)
  • Ergonomic tip ejection
  • Autoclavable body
  • Printed serial number (one each pipette)
  • Outer “O” rings (makes tip loading easy)
  • Dual “O” ring technology (guarantees the best tip fit)
