Sterile TPE Tube Sealer

A sterile sealer is a device which enables TPE tubes to be disconnected. This type of tool is very commonly used when cutting hoses/tubes in the pharmaceutical and biotechnology industry as any risk of contamination of the liquid pockets or tanks by external elements is avoided.

The physical properties of TPE hose allow it to be widely used in the biotech, pharma and medical sectors. This is particularly true as it has the ability to harden and melt, reversibly, under the effect of cold or heat.

Sterile Hose Sealers – the key facts

Each supplier brings their own technology in the manufacture of a sterile TPE tube sealer, which is one of the major reasons why a sealer can be for multiple or single use. Here are the principal advantages and disadvantages of each of these uses:

The multi-use sealer

In this type of machine, the tube is inserted between two clamps which squeeze it. The destruction of bacteria and the melting of the TPE tube are ensured by increasing the temperature of the clamps. A few seconds after this operation, the tube can then be cut using a simple pair of scissors.


Operators are less dependent on the manufacturer which allows you to choose the supplier of your hoses.

You don’t need to use a new component each time you use it which means a reduction in costs and logistics.

Your waste is considerably reduced.

The disadvantages

You must use thermoplastic elastomer (TPE) hoses or other tubes that can fuse together and withstand the rise in temperature (C-Flex® hose from Saint-Gobain).

The device requires electrical energy to operate.

The single-use sealer

To be able to use this machine, you must have small lugs which are integrated on the tubes in question. To disconnect the tubes, you must buy the hoses from specific manufacturers. In the event that it is possible to add them to third-party tubing, you will need to obtain a large quantity of hard plastic disconnectors/connectors.


You do not need to use a machine plugged into the mains to disconnect or install and connect two tubes.

The disadvantages

If the tubes are disconnected/connected incorrectly, there is a considerable risk of contamination.

You are much more dependent on the manufacturer.

You will constantly have to order lugs.

The use of this type of machine creates logistical constraints.

The MGA Technologies sterile TPE tube sealer

The sterile sealing machine manufactured by MGA Technologies allows you to reliably disconnect TPE tubing from your process devices. The hose is squeezed between two clamps and an electromagnet locks them when closed.

Here are the different phases of the sterile sealer process:

The tube is inserted between the two clamps (jaws) by the operator who then closes the tool.

The temperature of the two jaws increases to the melting point.

The temperature level is maintained for a few seconds in order to ensure that the tube is melted and any microbes that may be present are destroyed.

The tube is then cooled by a vane pump until it can be handled by the operator.

The electromagnet then unlocks the clamps to allow the operator to visually check that the fusion has been completed before the tube is then cut using a pair of scissors.

The technical characteristics of the MGA Technologies sealer

Compatible with 1/4”, 1/2” and 3/4” diameter hoses.

Suitable for disconnecting autoclaved or new TPE hoses such as C-Flex® tubes from Saint-Gobain.

Plugs into a 220/230 volt – 50/60Hz mains.

The machine can support different formats thanks to the different accessories that come with it.
