Frequently Asked Questions
Are these microcentrifuge tubes sterile?
No. These tubes ship non-sterile, making them well suited for general reagent handling, aliquoting, and routine benchwork. For sterile-dependent protocols, validate or autoclave per your lab's procedures, keeping HDPE temperature limits in mind.
What is the benefit of the tethered cap design?
The tethered cap stays attached to the tube body, reducing the risk of lost or mismatched caps during high-throughput processing. This design speeds one-handed opening and closing while helping maintain sample identity at the bench.
What material are these tubes made from?
Each tube is molded from natural HDPE (high-density polyethylene), a durable, low-extractable polymer commonly used for aqueous sample storage and aliquoting. The natural translucency allows quick visual checks of contents and fill levels.
How many tubes come in each pack?
These tubes are sold by the bag, with 1,000 tubes per bag (1000/Bag). The listed price is per pack. Tiered pricing is available for institutional and grant-funded volume purchases.
