3 Bio-Reaction Tubes Centrifuge Tubes Bio-reaction tubes offer a convenient and economical option for small scale, high density suspension cell culture Ideal for biological reaction applications that require sterile conditions and free gas exchange Aseptic conditions are maintained through 0.µm hydrophobic vented membrane Useful in the screening and optimization processes of suspension cells The 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 and supporting start-up testing procedures for larger bioreactors Feature a 0.µm hydrophobic membrane in the vent cap Easy-to-read black graduations Large white marking area Centrifuge Tubes are available with a variety of special features and packaging options. Please refer to the Centrifuge Tube Selection Guide below and pages - 8 for additional information on tube options. Temperature range of -80 C to 0 C (polypropylene only) Graduations are printed in bold easy-to-read black ink and are accurate to +/- % Save money with the ability to culture and centrifuge in one tube! Large white marking area provides excellent contrast for identification Easy to write on flat surface polyethylene (HDPE) caps feature integrated leak-proof seal Tubes include graduations molded into the conical bottom, ideal for pellet viewing and small volume quantification Black Centrifuge Tubes protect light sensitive compounds and eliminate the need to wrap tubes with aluminum foil BIO-REACTION TUBES Vent control labels for 0mL Bio-Reaction Tube Caps cover to of the cap vent openings to control the amount of gas exchange S, R/D F, NP, USP, A, PP Part No. Product (RCF) g 97 ml Bio-Reaction Tube 0/Re-sealable Bag ml Bio-Reaction Tube 0/Foam Rack mL Bio-Reaction Tube 0/Re-sealable Bag mL Bio-Reaction Tube /Foam Rack mL Self-Standing Bio-Reaction Tube 0/Re-sealable Bag BIO-REACTION TUBE CAPS S, R/D F, NP, USP, HDPE 97 CAP ONLY, Vented, Fits ml Bio-Reaction Tube /Re-sealable Bag 00 NA 977 CAP ONLY, Vented, Fits 0mL Bio-Reaction Tube /Re-sealable Bag 00 NA BIO-REACTION TUBE VENT CONTROL LABELS 978 Vent Control Label, 0mL Bio-Reaction Tube, Sheet 0 Sets/Page 0 Pages NA Ergonomic flip top cap is designed for single handed operation Centrifuge Tube Selection Guide Options listed below are for sterile, conical bottom, polypropylene centrifuge tubes unless otherwise noted.
