Laboratory rubber tubing

Laboratory rubber tubing

We manufacture laboratory rubber tubing for the transfer of liquids and gasses from one glassware to another. Their use, as the name suggests, is mostly for the medical industry, predominantly for experiments. The medical industry needs rubber tubing to make sure testings and experiments go as intended. The reason why rubber is an excellent choice is down to the fact that it is water-resistant and chemical resistant. 

But even so, our laboratory rubber tubing can be used for a wide range of applications. You’ll mostly find rubber tubing in the form of hoses. This is used to transfer the before-mentioned liquids and gasses. But rubber tubing can also come in the form of rubber stoppers. Rubber stoppers are small objects that we specifically design to fit the entrance of glassware. They are used to stop liquids and gasses from escaping. They’re seal-proof, will not come off, and come in a wide range of rubber materials. We manufacture our laboratory rubber tubing from a selection of materials including silicone, EPDM, FKM, Neoprene, and more. 

These materials are excellent for keeping glassware free of contamination. They’re not a short-term solution as our laboratory rubber tubing can last for years. Due to the unique properties of the rubber material, the tubing is very strong and very elastic. You can twist the hose without fear of snapping in half. In addition, we make our rubber tubing from the highest possible quality of rubber that is very durable. In addition to the anti-liquid properties that we mentioned earlier, there is no better way to transfer liquids and gasses or stop liquids and gasses from escaping than using our laboratory rubber tubing.

We make the tubing in all sizes. All you need to do is navigate to our size chart to figure out what size works best for your needs.

Rubber Hose Size Catalog

Compare tube bore, outside diameter and available wall thickness. Confirm material compatibility and operating requirements for the selected hose.
