2.3 Warranty
We guarantee the equipment as stated in the order/contract.
This warranty will expire in case of:
• Interference into or modification of the system without prior consent of the manufacturer;
• Improper use of the system;
• Insufficient maintenance of the system;
• Inappropriate operation of the system;
• Negligence of correct supply requirements;
• Application of third-part components to the system without prior consent of the
manufacturer;
• Alteration of program or configuration write-ups without manufacturer’s consent.
This applies to a single unit and multi-unit system types.
2.4 Operation Guidelines
MBRAUN glovebox systems are operated using inert gas enabling the user to handle
substances which are sensitive to oxygen and/or moisture. It is the responsibility of the user to
follow all local health, safety and environmental guidelines with regards to the handling and
disposing of substances which may be injurious to health. This also applies to the disposal of
vacuum pump oil and all components and filtering devices which come in contact with the gas
flow.
There is a risk of suffocation when working with high inert gas
concentrations.
On request, MBRAUN can recommend a personal measuring instrument that alerts the
operator to a reduction of oxygen content in the ambient air.
The following general safety guidelines must be considered when working with inert gas
concentrations:
• The selected location should have a “room” volume that is significantly larger than the
glovebox interior volume.
• The system should be located in a well ventilated area. This is especially important
during a purging procedure or when opening an active system (i.e. antechambers, etc.).
• All exhaust fumes should be vented through an adequate disposal/ventilation system.
Contact MBRAUN prior to the acquisition of the system if it is not
possible to adhere to all the above recommendations. This way the
system can be equipped with additional safety devices.
• Prior to performing maintenance or service inside an active system, remove one glove to
allow a slow equalization of the glovebox interior atmosphere with the ambient room air.
To better avoid the risk of suffocation, it is necessary for the
glovebox atmosphere to be completely replaced with ambient room
air prior to servicing the interior of an active glovebox.
Standard MBRAUN glovebox systems are not designed for the use
of strongly poisonous or radioactive substances. Use of these types
of materials must be coordinated with MBRAUN prior to the
acquisition of a system.
