Frequently Asked Questions
What is a serological pipette?
A serological pipette is a graduated disposable pipette designed for accurate liquid transfer with a pipette controller. It is commonly used for handling cell culture media, buffers, reagents, microbial cultures, and other laboratory solutions.
What sizes of NEST serological pipettes are available?
NEST Scientific serological pipettes are available in multiple capacities, including 1 mL, 2 mL, 5 mL, 10 mL, 25 mL, 50 mL, and 100 mL options. An ungraduated 2 mL aspirating pipette is also available for liquid removal applications.
Are NEST serological pipettes sterile?
Yes. NEST Scientific serological pipettes are available in sterile options with e-beam treatment, offered in individual and bulk packaging formats. Please check each product page for specific sterility and packaging details.
Do NEST serological pipettes have filter plugs?
NEST Scientific graduated serological pipettes are available with polyolefin fiber filter plugs to help reduce aerosol contamination and protect pipette controllers. The ungraduated 2 mL aspirating pipette is designed without a filter plug.
What is the difference between paper/plastic and plastic/plastic packaging?
Paper/plastic packaging features a traditional peelable sterile pouch, while plastic/plastic packaging removes the paper layer from the wrapper. Plastic/plastic packaging can be preferred for cleanrooms and particle-sensitive environments.
Can serological pipettes be used with electronic pipette controllers?
Yes. NEST Scientific serological pipettes are compatible with suitable manual and electronic pipette controllers. Controller compatibility should be confirmed based on pipette capacity and diameter, especially for 50 mL and 100 mL pipettes.
What is the difference between a serological pipette and a micropipette tip?
Serological pipettes are designed for milliliter-scale liquid transfer using pipette controllers, while micropipette tips are typically used for microliter-scale dispensing with adjustable pipettes. They serve different laboratory applications and volume ranges.

Nest Scientific Serological Pipettes are precision-molded from USP Class VI virgin polystyrene in an ISO 7 cleanroom, in a facility that meets both cGMP (21 CFR part 820) and ISO 13485 standards. Available in seven volumes (1, 2, 5, 10, 25, 50, and 100 mL) each pipette is individually wrapped in paper/plastic peelable packaging to ensure purity. Each lot is tested to be sterile, DNase- and RNase-free, pyrogen-free, and BSE/TSE-free. Ideal for cell culture, general laboratory use and QA/QC testing.
