Laboratory stoppers and laboratory caps

Laboratory stoppers and laboratory caps are classic items of laboratory equipment and are permanently used in science, technology and enterprise. They are available in numerous versions with very different properties.

Silicone rubber stopper

RCT presents laboratory stoppers made of silicone (silicone rubber) – platinum-cured for biotechnology, pharmaceutical technology, medical technology and the food industry with a shore hardness A of 45°. These rubber stoppers are FDA-compliant or BfR-compliant.

Other silicone laboratory stoppers for the food and pharmaceutical industry as well as for biotechnology, the beverage industry, the dairy industry and container technology are presented with a shore hardness A of 50°. These rubber stoppers are also FDA-compliant and BfR-compliant and are suitable for temperature ranges from -60°C to +200°C.

Laboratory caps made of silicone - conical or straight, for optimal protection of pipes and hose ends with a shore hardness A of 62° and FDA compliance, are also part of the range. Silicone sponge plugs are extremely heat-resistant up to +180°C – and persistently for 10 hours.

Made of elastomers or natural rubber

Rubber plugs made of NR (natural rubber/latex) are chemically resistant, ozone-resistant and physiologically harmless. The shore hardness A is given as 40°.

These include, for example, laboratory stoppers made of elastomer rubber, such as FPM/FKM with excellent chemical resistance. This can be seen in particular with regard to fuels, oils, greases, hydraulic oils, alcohols and acids, but especially with regard to aliphatic as well as aromatic and halogen-substituted hydrocarbons.

More materials: aluminium, pulp, polypropylene

Laboratory caps made of aluminium for sealing test tubes, in particular culture tubes, are also part of the standard range. They are available as test tube caps with a handle or with a claw or without a handle.

Laboratory stoppers made of pulp are used to seal Erlenmeyer flasks, culture flasks or culture bottles, test tubes and bacterial cultures.

You can order laboratory stoppers and laboratory caps in the Reichelt Chemietechnik online shop

RCT keeps its entire range of laboratory stoppers and laboratory caps in stock as standard, so that there is a short-term readiness for delivery. This also applies to the caps and stoppers in the category Closure Elements as well as to many other items from the laboratory. 

In our shop you can order numerous protective caps, standard ground stoppers, test tube caps and silicone sponge stoppers for laboratories, medical technology or workshops, even in small quantities. This, on top of the excellent quality of our products, is a distinguishing feature of rct-online.de. Customers from Germany, Europe, Asia and even the USA have appreciated this from Reichelt Chemietechnik for over 35 years. Convince yourself of our products and services!
