Pharma Tube Sealing Machine Tool

The pharmaceutical tube sealing machine tool, or sealer, is used in clean rooms to separate sterile process equipment connected by tubes.

Typically used in pharma and the medical sectors, the sealing machine is designed to avoid any risk of proliferation of microorganisms in machines and tubes at the time of disconnection.

It plays a key role in contamination control and ensures total integrity of the manipulated fluid thanks to its hermetic process. it is widely used in sensitive applications (bsl2, bsl3+…) where safe and reproducible operations are required.

Legacy solutions for sealing pharmaceutical tubes

There are currently two main types of tools available on the global market for sealing pharmaceutical tubes.

Single-use solution

Many manufacturers offer single-use disconnection devices that can be integrated upstream or downstream of a production line. The principle is simple: once the disconnector is positioned, the line is cut mechanically or using a machine. These systems, generally made of plastic, are easy to install and suitable for occasional or low-volume operations.

However, repeated use can become restrictive. They generate more waste and lead to additional costs linked to the purchase of proprietary consumables. Moreover, poor fixation can compromise the sterility of the disconnection, which remains a critical risk in an aseptic environment.

See the sterile disconnector product page for more information.

Multi-use sealing machine

Multi-use sealing machines operate using the thermofusion principle, which enables a clean and sterile separation without any additional effort. Sealing is performed directly by the machine, without adding connectors or disposable parts, which significantly reduces operating costs and logistical complexity.

This solution is particularly appreciated in laboratories, hospitals and bioproduction units, where reliability and repeatability are essential. The only constraint lies in the material compatibility of the tube, which must be fusable—typically TPE (such as Saint-Gobain’s C-Flex® tubes). A simple pair of scissors is then enough to complete the cut once the sealing is done.

Which category of tools should you choose?

To choose between these two solutions, it is essential to evaluate the real needs of your production. The first criterion is therefore the volume and frequency of your operations. If your company produces large quantities of identical or standardized batches, a multi-use sealing machine represents a strategic investment. It offers great flexibility, seals different types of tubes and reduces downtime associated with configuration changes.

Conversely, for smaller-scale production, laboratory tests or batches requiring frequent adjustments, single-use systems are generally simpler and more economical in the short term. They can be deployed quickly and require minimal operator training, making the management of varied batches easier.

In summary, the choice depends on your production pace, the diversity of your processes and your cost-management policy. The goal is not to oppose the two methods but to identify the one that provides the best balance between performance, safety and cost-effectiveness for your activity.

Additional points to consider when choosing

Multi-use machines come with a higher initial acquisition cost due to their more complex technology and increased versatility. However, they deliver long-term profitability, especially for companies handling multiple tube types and sterile processes. This choice reduces spending on consumables and limits dependence on proprietary components.

Single-use machines, on the other hand, appear more affordable to purchase, but their overall cost can rise quickly if multiple devices are required to handle different tube formats or diameters. Their main advantage remains ease of use and maintenance, ideal for moderate-flow environments or temporary installations.

Finally, note that multi-use models require more regular maintenance due to their more advanced technical architecture. However, they are designed to withstand intensive use, with robust components and extended service life. In contrast, single-use models offer easier maintenance but wear out faster when used beyond their nominal capacity.

Pharmaceutical Tubes

Pharmaceutical tubing is widely used in many fields such as medical, biotech, and pharma. Among the most used are Advantaflex® tubes and C-Flex® tubes. The applications of these tubes are various and allow you to use them for sterile processes. The different applications of pharmaceutical tubing include:

• Cell culture operation
• Manufacturing in the biopharma sector
• Sterile process connection
• Single use assembly
• Purification operation
• Preparation of buffers and media
• Ultrapure water system
• Single use fluid transfer
• Sterile process disconnection
• Laboratory R&D
• Products for diagnosis

MGA Technologies pharma tubes sealing machine tool

The MGA Technologies machine tool is used to seal pharmaceutical tubes to disconnect process devices by pinching them in a locked jaw. The locking of the tube by the machine is done thanks to an electromagnetic magnet after closing clamps for a 100% sterile lock.

The operator then starts the cycle to seal the tube using fusion. The ceramic tool heats up to a temperature that slightly exceed the melting point of the pharma tube (C-Flex). A short phase of temperature maintenance makes it possible to guarantee the melting and to destroy any possibility of development of micro-organisms that would have slipped between the clamp and the tube. Then, a vane pump (included in the machine tool) cools the tube to a safe temperature for the operator. Finally, the machine releases the clamps from the tube. After a visual verification of the fusion, the tube can be sectioned easily with a pair of scissors.

Technical characteristics of the MGA Technologies sealer

The technical characteristics of the MGA Technologies sealer:

• Machine tool adapted to seal C-Flex and TPE tubes, new or autoclaved diameter 1/4 “, 1/2” and 3/4 “,
• Several aluminum “jaw” sizes included (for different tube diameters),
• Usable on 110V / 220 / 230V – currents of 50 / 60Hz.

Why choosing the multi-purpose sealing machine tool?

The MGA Technologies sealing machine tool allows you to completely plug and unplug tubes repeatedly without having to buy new components.

This machine has the advantage of being integrated into FDA processes. To seal pharmaceutical tubes, it does not require a containment area and there is no risk of cross-contamination. Operators can use this machine in complete safety. It is also cleanable, making it easy to use and maintain.

Designed to be used in a cleanroom areas (ISO5 dynamic), this pharmaceutical tube sealing machine can also be used outside those areas. It is a great advantage in terms of productivity gain. Indeed, your operators do not have to go into the sterile area to perform the operation.

Advantages of the pharmaceutical tube sealing machine

The pharmaceutical tube sealing machine offers many advantages:

It is easy to use and helps you reduce your costs. Indeed, you do not need to purchase proprietary lugs or connectors to use pharmaceutical tubes. You simply insert the tube into the machine to seal it.

The machine can be used over the long term. You can seal different brands of TPE tubes such as Advantaflex®, C-Flex®, and others.

The sealer is locally manufactured. In fact, it is made in France, which ensures dedicated technical support throughout the country.

Additional advantages worth noting

Another significant advantage of this machine is that it operates automatically. To guarantee the quality of tube sealing, the cycle is fully automated. The machine is reliable and robust, with blades offering an excellent lifespan capable of performing up to 200 seals.

Professional maintenance

MGA Technologies can also provide maintenance for the pharmaceutical tube sealing machine. This includes preventive maintenance as well as calibration of your equipment. Spare parts are kept in stock, allowing repairs to be carried out quickly if needed.

Significant savings

The MGA Technologies sealer allows you to save money and time, while avoiding the logistical burden of purchasing consumables and reducing waste — contributing to a cleaner and more sustainable environment. Finally, you benefit from French manufacturing, as the machine is designed and produced in Civrieux-d’Azergues, near Lyon.
