Westlab offers 50ml Centrifuge Tubes, perfect for various applications such as centrifugation, sample storage, and molecular biology research. These tubes feature a conical bottom design and are ETO sterilised to ensure optimal cleanliness and safety.
Manufactured from medical-grade polypropylene, the tubes are paired with leak-proof HDPE caps, providing secure containment for samples. They are certified as non-pyrogenic, non-cytotoxic, RNase-free, and DNase-free, guaranteeing the integrity of sensitive samples.
The flat top design allows for convenient writing and labelling of samples. Additionally, these tubes are resistant to alcohols and mild organic solvents, enhancing their versatility. With a centrifugation capability of up to 4,000G, these non-skirted tubes are reliable tools for laboratory procedures.

What low (-80C / -40C freezer?) and high (+121C autoclave?) temperatures are these rated to?
Question by: Lara on 6 Feb 2024, 8:01 pm
The temperature resistance of 663-819 is:
1. +121°C (autoclave): The tubes can withstand autoclaving at 121°C at 15 psi for 20 minutes, taking into consideration that the appropriate caps are either removed from the tubes or have a slightly loose closure.
2. -40°C/-80°C (freezer): It is not recommended to store our 50ml tubes at low temperatures, as previous tests on the same polypropylene material grade exposed to low temperatures yielded inconsistent results.
For further clarification, if you have any inquiries regarding the provided information, please let us know the intended use of 663-819 or testing procedures.
