Bio-Reaction Tubes offer a convenient and economical option ideal for small scale suspension culture or biological reaction experiments that require aseptic conditions with gas exchange. Tubes are available in 15mL and 50mL conical bottom and 50mL self-standing sizes. They feature an ultrasonically welded 0.22µm hydrophobic membrane, easy-to-read black graduations and a large white marking area.
