XXTuff™ Reinforced Microvials
Cat. No. 330TX, XXTuff™ non-sterile, reinforced 2 ml vial and cap, 500 count
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 screw cap and o-ring seal. However, it is molded from a 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 a standard microvial.
*When doing CryoGrinding, a varient of dry-grinding done at liq N2 tempertures, we recommend using our stainless steel microvials. Exteme cold makes all plastic microvials too brittle to withstand beadbeating with steel beads.
