This specially reinforced vial is manufactured exclusively for BioSpec Products. The XXTuff microvial has the same dimensions as a standard 2 ml microcentrifuge vial with a screw cap and o-ring seal. However, it is molded from special polypropylene resin and has been reinforced in critical areas.
Unlike standard microvials, the XXTuff vial is able to withstand the rigors of dry grinding using steel beads*. Tests show that the XXTuff vial is over 10 times more durable than standard microvial.
This vial and cap can be autoclaved.
*When doing CryoGrinding, a variant of dry-grinding done at liq N2 temperatures, we recommend using our stainless steel microvials. All plastic microvials become too brittle to withstand beadbeating with steel beads at extremely low temperatures.
