A testimony of the MBRAUN’s excellence is the application lab, in which clients can work with our research team to test and verify coating and material purification processes.

First Care Kit

The First Care Kit of MBRAUN for wearing parts offers you the perfect collection of materials,
which become naturally blunt after a while.

 Consisting of:

  • One pair of gloves selectable anatomical or ambidextrous
  • Two dust filters
  • One-liter oil for vacuum pump
  • Internal glove port cover
  • Change instructions

Leak Test Device

The Leak Test Device is used e.g. within the framework of a quality assurance system or after maintenance to check the leak tightness of containment enclosures like isolators or gloveboxes.
The Leak Test Device works fully autonomous and performs complete tests according ISO 10648-2. Only a standard PC or Laptop needs to be added to control the measurements. The system will provide a full test report with all measuring data.

  • Compact design with powerful integrated gas purifier unit (DP as option for 24/7 purification)
  • Available in 12 sizes (single sided or double sided)
  • Modular box design for easy extension

FAQ

FAQ

What gasses do I need to run my glovebox?

In standard applications an inert gas supply of 6bar (80-90 psi) is required for operation of the system. Acceptable gasses for system use are Argon, Nitrogen and Helium.

The systems will also need a forming gas supply for regeneration of the purifier column. The gas should be 3%-10% hydrogen with the balance being the working gas used in the system. The forming gas should be supplied with a low range regulator (approx: 0-20 psi) so that flow can easily be adjusted when starting the regeneration process.

Does my system need to be connected to a facility exhaust? If so what should be connected?

Connection of the facility exhaust is optional and not strictly needed for system operation. For the installation and startup of a system, facility exhaust is not normally required.

While connecting the system to an exhaust is not required for proper operation, it is strongly recommended on systems where potentially hazardous substances are used.

If you choose to connect your system to an exhaust the main things that normally need to be connected are the purge valve, vacuum pump, and regeneration exhaust outlet.

What maintenance does my glovebox need and where can I get the required parts?

Typically the recommendations in our maintenance guide are suitable for most systems. If you have questions regarding the maintenance of your specific system please contact us.

What will happen to the system if there is a power outage? Should we do anything to prepare for a scheduled outage?

A power outage will not damage the system, when power returns the systems will continue in the same state it was in before the power outage. If an outage is scheduled it is best to stop work, turn off the systems functions and power down the system. In the event of a power surge or power fluctuation the frequency inverter for the circulation blower may experience an error. In this case simply turn circulation off, reset the error at the frequency inverter and turn circulation back on.

Do my Oxygen and Moisture probes need to be calibrated?

Frequency of calibration is dependent on the requirements of the user. The sensors have a specified drift of <10%/year at 10ppm. For some research applications it is acceptable to go for several years between calibrations of the analyzers. In production applications the sensors should almost always be calibrated annually.

My system displays the alarm 'Clean the H2O-sensor-refer to instruction manual'. What should I do?

This alarm automatically comes on every 2000 hours of sensor use to act as a reminder to service the H2O probe. The H2O sensor needs to be periodically cleaned and coated with phosphoric acid. This should typically be done about every 3-6 months. Refer to the instruction manual for directions on how to clean the probe. The alarm can be reset by navigating to the 'Common Parameters' screen, selecting 'Service H2O Probe', resetting the counter to zero and acknowledging the alarm. It is important to note that cleaning the probe is different than calibrating the sensor.

My glovebox displays the message 'Purifier: Filter 1 input main valves not open'. What does this mean and how can I correct it.

This message indicates that the main valves for the purification system are not fully open. These valves are electro-pneumatic and require approximately 80psi (5.5bar) to remain open. This error is almost always caused by the supply pressure being too low.

To correct the problem, check and adjust the supply pressure.

My system displays the alarm 'Motor protective switch vacuum pump VPG 1 activated'. What does this mean and how can I remedy it?

This means that the circuit breaker for the vacuum pump has tripped, this is normally due to the vacuum pump drawing too much current, but could also be because of a power surge or other anomaly.

The oil should be checked in the vacuum pump to be sure that it is clean and completely filled. Once this is verified the circuit breaker in the main electrical cabinet can be reset and the pump can be turned back on.

If the breaker continues to trip the current draw of the vacuum pump should be measured. On some systems the vacuum pump circuit breaker will have a variable amperage dial. In this case the allowable amperage can be increased to account for a small increase in current draw as the pump ages.

Does my glovebox system need cooling water to run efficiently?

Not necessarily, A heat exchanger is integrated into the gas purification system to achieve optimum working temperatures inside the glovebox. In hot climate zones it is recommended to connect the cooling water to the gas purifier to maintain comfortable working environments inside the glovebox. In laboratories equipped with air conditioner units which already maintain constant temperatures it is not needed to hook up cooling water to the gas purification system.

My system displays the alarm 'Blower GB1 motor protective switch activated or error frequency controller'. What does this mean and how can I remedy it?

This means that there is an error indicated on the frequency controller for the blower or that the breaker for the blower has tripped, this can be caused by excessive load or wear on the blower or by a power surge or fluctuation.

To rectify the issue, open the electrical cabinet and locate the frequency controller, it is typically labeled ‘U1’. Note the error displayed on the controller. Then turn circulation off. Verify the box filters are clean and change if needed. With circulation off reset the controller by pushing the appropriate key on the controller. Once the code is cleared turn circulation back on. 

If the issue persists contact M. Braun Service with the project number of your glovebox and the error code from the controller. 

If the LCD on the controller is off, contact M. Braun Service.
