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 0.22µm 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 and supporting start-up testing procedures for larger bioreactors Can be used for lyophilization Feature a 0.22µm hydrophobic membrane in the vent cap Easy-to-read black graduations Large white marking area (300 per CS)

Assorted color cap tubes allow easily color coding of samples for quick identification, customization, and increased productivity Users report coding each color to a day of the week, a member of the lab, or a specific procedure Graduations are printed in bold, easy-to-read black ink and are accurate to +/-2% 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 Convenient zip-closure bag is a practical alternative to folding and taping opened bags (500 per CS)

Audible "snap!" gives you the confidence that the tube is completely closed Easily open or seal the tube with one hand; same hinged cap style as micro centrifuge tubes Elongated lip on attached cap prevents finger contact with tube, reducing cross contamination Ideal for sample storage, collection and experimental procedures Single-piece design is easy to use in the lab or the field Offers savings advantage versus traditional flip-top screw cap Available in conical and self-standing bottoms (500 per CS)
