VWR® Bio-Reaction Tubes are manufactured from high-grade, gamma-resistant polypropylene. They offer a convenient and economical option for small scale, high density suspension cell culture.

• Available in 15 ml and 50 ml formats
• Conical bottom and self-standing bottom
• Easy-to-read black graduation and a large white frosted writing area
• Save money with the ability to culture and centrifuge in one tube
• Engraved graduation at the conical bottom of each tube
• Leak-proof, DNase-/RNase-free, and non-pyrogenic

• Easy-to-read black graduations in ±2% increments

Bio-Reaction Tubes consist of centrifuge tubes with a 0.22 μm hydrophobic membrane in the vent cap which allow gas exchange. These tubes are perfect for biological reaction experiments that require aseptic conditions with free gas exchange. Maximum RCF is 12000×g for 15 ml tubes, 16000×g for 50 ml conical bottom tubes, and 6000 ×g for self-standing tubes.

Manufactured in a Class 100000 clean room environment and under EN ISO 13485:2003 and ISO 9001:2008 quality management system. Sterilized by electron beam irradiation.
