XXTuff2 Reinforced Microvials

New XXTuff2 microvial improves on BioSpec's proven reinforced vials. The new XXTuff2 microvials feature a skirted, free-standing bottom that reduces blow-outs to the bottom of the tube that can occur with some dry grinding protocols. The XXTuff2 microvial also features a natural-colored cap. This eliminates the reddish tint some observed in their sample due to the abrasion of the red cap in the original XXTuff vials. Cat. No. 330TX821, XXTuff2™ self-standing, non-sterile, reinforced 2 ml vial and cap, 200 countThis specially reinforced vial is manufactured exclusively for BioSpec Products. The XXTuff2 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 XXTuff2 vial is able to withstand the rigors of dry grinding using steel beads*. Over 10 times more durable than a standard microvial.*When doing CryoGri
