Centrifuge Tubes
Glass and plastic tubes designed for use in centrifuges; available in a variety of volume capacities, materials, configurations, RCF ratings, and closure types; may be sterile or non-sterile; may have graduations indicating volume on the tube.
Centrifuge tubes are used to contain liquids during centrifugation, which separates the sample into its components by rapidly rotating it around a fixed axis.
Most centrifuge tubes have conical bottoms, which help collect any solid or heavier parts of the sample being centrifuged. Centrifuge tubes must also be able to withstand the centrifugal pressure created during their use, and their specifications may indicate the maximum speed at which they can be safely used.
Centrifuge tubes are available in various styles, sizes, and materials
- Capacities: Range from 0.1mL to more than 100mL; the most common sizes are 15mL and 50mL (centrifuge) and 1mL and 2mL (microcentrifuge)
- Closures: Screw-on plugged or flat caps; may be attached or separate
- Markings: May have writing areas, graduations, or other markings
- Shape: Conical- or round-bottomed; if conical, choose skirted free-standing versions
- Material: Glass or plastic resin; the latter include polypropylene, polystyrene, PET, and PPCO
- Sterility: Sterile or nonsterile; may be heat- or gas-sterilized
- Packaging: Bulk or racked tubes
- Color: Choose amber or black plastics for light-sensitive samples

Andwin Scientific 15 ML CENTRIFUGE TUBE WITH CAP
The 15 mL conical screw cap centrifuge tubes are made with copolymer polypropylene. These tubes feature a large white labeling area that permits easy sample identification and easy-to-read graduations at 1 mL that allows precise measurements. This product comes with high density polyethylene (HDPE) caps that have a sealing ring for a leak-proof seal. It comes in a pack of 500 tubes.
Chemglass Life Sciences 50mL Bio-Reaction Centrifuge Tubes, PP/HDPE, Sterile
Mini Bioreactor / Bio-reaction tubes offer a convenient and economical option for suspension cell culture. Bio-reaction tubes consist of centrifuge tubes with a 0.22µm hydrophobic membrane in the vent cap. These tubes provide an environment perfect for small scale suspension culture or biological reaction experiments that require aseptic conditions with free gas exchange. Bio Reaction tubes are extremely useful in the screening and optimization processes of suspension cells. The reaction parameters can be optimized using small amounts of materials which can maximize the number of parallel experiments that can be done at the same time.Bio-reaction centrifuge tubes are available in 50mL conical bottom. The tubes feature easy-to-read, black graduations and a large, white marking area. Each tube has a vent cap with a 0.22µm hydrophobic membrane ultrasonically welded into the cap to allow gas exchange.
