Pipetkop

Pipetkop, in many contexts understood as the pipette tip, is a disposable plastic attachment used with a micropipette to aspirate and dispense precise volumes of liquid. The tip forms the interface between the pipette’s piston and the sample, and it is typically designed for single use to prevent cross-contamination and maintain accuracy in measurement.

Most pipetkop tips are made from polypropylene and can be sterile or non-sterile. They may be standard (unfiltered) or include a filter to prevent aerosols and liquids from entering the pipette shaft, which helps protect both the sample and the instrument. Tips come in various volume ranges and are commonly color-coded by manufacturer to indicate fit and capacity. They are designed to fit specific pipette brands or styles, such as Eppendorf-style or Gilson-style tips, and some tips are marketed as universal, although fit may vary across models.

Design considerations include the internal bore shape, the external shaft diameter, and the conical tip geometry, all of which influence accuracy, flow rate, and ease of use. Proper selection of tips involves matching the pipette model and the intended volume range, as well as choosing sterile or filtered options when contamination control or aerosol protection is required.

In use, pipetkop tips are replaced between samples and disposed of according to laboratory waste procedures. They are essential components of routine liquid handling in molecular biology, clinical chemistry, analytical chemistry, and environmental testing, contributing to precision, reproducibility, and contamination control in experiments.
