Frequently Asked Questions
Are these specimen containers sterile?
No. These vials ship non-sterile and are intended for general specimen collection, storage, and non-sterile applications. If your protocol requires sterility, validate or autoclave per your lab's procedures, noting HDPE temperature limits.
What is the actual capacity—20 mL or 30 mL?
The vial is rated at a 20 mL working volume within a body sized like a 30 mL centrifuge tube, giving generous headspace. This makes the container well suited for 20 mL samples while reducing spill risk during handling and transport.
Is the HDPE compatible with autoclaving?
HDPE has a limited heat tolerance and is generally not recommended for repeated autoclaving, which can deform the container. For heat sterilization, confirm against your validated cycle or select a sterile or autoclavable alternative.
How many containers come in each pack?
Each bag contains 1000 containers with caps, priced per pack. Bags carry lot numbers for traceability, and tiered institutional pricing applies to multi-bag and recurring purchases.
