Dynalon 276145 Green Test Tube Stoppers
These Dynalon 276145 stoppers fit test tubes with 11 to 13 mm necks. Made from green polyethylene they resist abrasion water acids alcohols bases and esters. The solid top measures 0.5 in across and 0.6 in high with zero holes. They meet FDA REACH and RoHS standards and come in a pack of 1000.
Seals standard tubes without extra hardware
Each stopper presses into an 11 to 13 mm tube opening and needs no screw closure or special tool. The polyethylene material handles common lab chemicals so you can use the same stoppers across many protocols. Because they are not autoclavable plan a different closure for heat sterilisation cycles. The bulk pack keeps a bench stocked for high-throughput work.
Replaces loose foil or worn rubber plugs
Labs that currently seal tubes with foil parafilm or degraded rubber gain a consistent reusable fit. The jump is worth it when you need a documented material that satisfies FDA REACH and RoHS and when you want to stop improvising with makeshift covers. Not for users who require autoclave-safe closures or stoppers with holes for needles or venting.
