Frequently Asked Questions
What is the difference between the cap styles offered?
The 1.5 mL colored tubes use an attached snap cap for quick one-handed sealing, while the 2 mL amber tube features an attached flat top cap suited to labeling and stacking. Both keep the cap tethered to reduce loss.
Are these tubes autoclavable?
Polypropylene tolerates standard steam sterilization. Verify autoclave cycles against your lab's protocol, since repeated cycles can affect tube clarity and cap seal performance over time.
Why choose the amber variant?
Amber polypropylene blocks light to protect photosensitive samples such as fluorescent dyes, certain vitamins, and light-degradable reagents during handling and storage.
How are the tubes packaged and sold?
The 1.5 mL colored tubes are priced per bag. The 2 mL amber tube ships as a unit of 10 bags at 500 tubes each, totaling 5,000 tubes per case.
