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
CELLTREAT Scientific Products 15mL Centrifuge Tube, Flip Top Cap - Bag, Sterile
CELLTREAT Scientific Products 15mL Centrifuge Tube with Flip-top Cap. Graduations are printed in bold, easy-to-read black ink and are accurate to +/-2%.

Tubes include graduations molded into the conical bottom, ideal for pellet viewing and small volume quantification. Convenient zip-closure bag is a practical alternative to folding and taping opened bags. Ergonomic flip top cap is designed for single handed operation. RNase/DNase free and non-pyrogenic. Max force (RFC) g 9400. Every case is printed with the lot number for quality traceability. Packaged sterile, 25/re-sealable bag, 500/case.
CELLTREAT Scientific Products 50mL Bio-Reaction Tube - Bag, Sterile
Bio-reaction tubes offer a convenient and economical option for small scale, high density suspension cell culture. Ideal for biological reaction applications and free gas exchange. Aseptic conditions maintained through 0.22?m hydrophobic vented membrane. Useful in the screening and optimization processes of suspension cells. Reaction parameters can be optimized using small amounts of materials, maximizing the number of parallel experiments that can be performed simultaneously. Ideal for suspension cell culture, bacterial growth, seeding larger bioreactors, supporting start-up testing procedures for larger bioreactors, and lyophilization. Vent control labels for 50mL Bio-Reaction tube caps cover 1 to 5 of the cap vent openings to control the amount of gas exchange. Reaction parameters can be optimized using small amounts of materials, maximizing the number of parallel experiments that can be performed simultaneously.
