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

Alkali Scientific ASI™ Screw-Cap 5mL MacroTubes, 5mL Screw-cap MacroTube Vivid™, sterile, w/ vivid printed graduation w/ attached screw caps in foam racks, 500/Case
ASI Screw-Cap 5mL MacroTubes Alkali Scientific’s MacroTubeª 5mL Centrifuge Tubes are compatible with standard centrifuges and have exceptional clarity. Useful from -86°C to 110°C, these conical-bottom tubes are excellent for boiling and for sample preservation at very low temperatures. They come as gamma sterilized in racked packaging with attached caps or in non-sterile bags with separate caps. Our foam racks are similar to the packaging normally associated with 15mL tubes (upright with caps attached), but they require about 60% less storage space. Gamma sterilized, racked conical tubes or non-sterile bags Exceptional clarity RNase, DNase & Pyrogen FREE Compatible with standard centrifuges Withstands up to 25,000xG Dual graduations at every 0.2mL and 0.5mL
