Frequently Asked Questions
Are these microcentrifuge tubes sterile?
No. These tubes ship non-sterile, making them suited to general reagent aliquoting and sample storage. For sterile applications, autoclave compatibility depends on your protocol; validate HDPE temperature limits before processing.
What does the tethered cap design provide?
Each cap stays attached to its tube, reducing the risk of misplaced or swapped caps during fast bench work. Such integration improves sample integrity tracking in high-throughput aliquoting.
What is the working volume of a 0.4 mL tube?
Nominal capacity is 0.4 mL. Practical fill volume should leave headspace for cap closure and any centrifugation expansion, so dose below the rated maximum for reliable sealing.
How many tubes are in a pack?
This product is sold as 1000/Bag at the listed per-pack price. Multiple bags can be ordered, and tiered institutional pricing applies to larger procurement volumes.
