Stoppers

The Matrix™ SepraSeal sealing mats are suitable for securely sealing sample tubes with or without 2D code. For sample access, the caps can be removed with the practical cap removal tool (Cat.-No. 6.254 390, please order seperately) or pierced once. The pre-slit versions are suitable for multiple piercing. The self-sealing function of the pre-slitted elastomer maintains sample integrity.

• For storage down to -20 °C
• Individual closure or closure of 96 sample tubes simultaneously possible
• Good chemical resistance
• Low evaporation rate

With the Matrix™ DuraSeal sealing mat (Cat.-No. 4.658 312), sample tubes are permanently sealed. The sealing mat is pre-slit for sample access and has a v-shaped design. The special elastomer ensures that the integrity of the sample is maintained. Suitable for sample storage down to -80 °C.

Hollow, with sealing rings and square grip. Autoclavable (121 °C).

Materials used PP and PTFE. Flexible modular system. Five different hose diameters (3.2 mm, 6.0 mm, 8.0 mm, 10.0 mm and 12.0 mm) can be connected. Sterile pressure equalisation is possible through use of membrane filter. Unused ports can be provided with a blind cap. Typical applications: safe transfer of liquid media within a closed and sterile system (evaporation is reduced).

• Autoclavable
• Maximum temperature 140 °C

Brass, with handles.

Consequently the DURAN PURE premium lip seal cap is particularly suitable for use in the pharmaceutical, chemical and food industries. Due to the integrated lip seal, no further seal is needed to provide tight sealing of the bottles. Therefore it is ideal for storage and transport of sensitive products.

Alternative Glass vacuum filter holders, glass frit Alternative Filter holders, Type 16309

Connecting equipment and fittings with GL threads with hard-walled tubing or tubes made of glass, plastic or metal. Fixing probes, thermometers, dip tubes or cables in reaction vessels. Black screw caps made of PPS, inner parts consisting of a v-ring (PPS), a tapered ring and a sealing ring (both PTFE) as well as an o-ring (FKM) for tubing diameters under 3 mm (not exposed to the medium). Good chemical resistance, the medium is only exposed to PTFE. Temperature resistant from -50 to 250 °C, pressure stable up to 10 bar, suitable for vacuum.
Laboratory threaded joints, GL 14

Cap from PP, membrane made of PTFE with 0.2 µm pore size. Ideal for autoclaving processes because the membrane permits pressure equalisation and tight sealing, reducing the risk of contamination. Temperature resistant up to 140°C. Typical applications: storage or transport of gas generating media, autoclaving of media.
