Caplugs® Evergreen 0.4 mL Conical Microcentrifuge Tubes with Tethered Caps, Polypropylene, Natural, 1000/Bag
These 0.4 mL conical microcentrifuge tubes are molded from natural polypropylene with attached tethered caps that stay with each tube during workflows. Bench scientists rely on them for small-volume sample aliquoting, enzyme and reagent storage, and short-spin separations where cap loss and cross-contamination must be minimized.

Frequently Asked Questions
Are these microcentrifuge tubes sterile?
No. They are supplied non-sterile in bags of 1000. For applications requiring sterility, autoclaving or alternative sterilization should be validated against your protocol before use.
What material are the tubes made from?
The tubes are molded from natural polypropylene (PP), which offers low protein binding, broad chemical tolerance for routine lab reagents, and reliable performance at refrigerated and frozen storage temperatures.
What is the benefit of the tethered cap?
The tethered cap stays attached to each tube, reducing the risk of lost caps, mix-ups, and cross-contamination during pipetting, vortexing, and sample handling at the bench.
What pack size and SKU should I order?
This is SKU 214-3027-030, supplied as 1000 tubes per bag. It is a single-variant listing; volume tiered pricing for institutional and grant-funded orders is available.
