Test tube closures ensure samples do not leak or are contaminated by providing a reliable seal. Securely mix or store small samples with these tops that allow one-handed sealing. Offered in a variety of colours, identification is made easier. Closures come in screw and snug-fit plug designs to fit any test tube opening style. Resistant to high temperatures, the versatile test tube closures can withstand heating applications while the chemical resistance guarantees limitless sample compatibility.

VWR® Safe-T-Flex, Låg til reagensglas

Supplier: VWR Collection

Safe-T-Flex låg har et enestående, fleksibelt, over-locking-design, der låser sikkert på ydersiden af rørets kant, og kan fjernes med én hånd.

Denne specielle forsegling beskytter mod aerosoler fra højinfektiøse organismer som fx TB og HTLV-III virus. De er farvekodede for nem prøveidentifikation og for at beskytte mod krydskontaminering. Lågets top kan desuden nummereres eller mærkes med mærkeblæk. Selvlåsende låg holdes på plads uanset position og holder indholdet sikret under transport. Væsketæt forsegling kan modstå centrifugering, omrøring, køling og frysning.
