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

Chemglass Life Sciences Omnitop Sample Tubes, 50mL, with 18" C-Flex Inlet, Silicone Dip Tube, Seal Tube
Transfer of biopharmaceutical products and reagents in a closed system. Gas exchange transfer. Sampling of biopharmaceutical products and reagents in a closed system. Storage of biopharmaceutical products and reagents. Use with bench top, pilot plant and production bioreactors. Use with sterile connecting devices and thermal or RF tubing sealers. OmniTop Sample Tubes are convenient devices that can be used to obtain fluid samples. Each OmniTop tube comes with a pre-attached 0.2um vent filter and 18" of C-Flex tubing. They are available with or without internal dip-tubes to facilitate removal of the fluid inside. OmniTop Samples Tubes can be aseptically connected to your bio reactor or other device using standard tubing welders. Sample Tubes can also be aseptically sealed and removed (wet or dry) using tubing sealers. Blue caps indicate the tubes are polypropylene. Purple caps indicate the tubes are polystyrene. For other sample tubes, see CLS-1407-T-325, CLS-1407-T-312, CLS-1407-T-310.
