A new system solution for active storage enables future safety-optimised and paperless workflow for the user. Filling processes are saved, documented and can be transmitted to suppliers by modem.

The new media management system for active storage is a safety cabinet and control centre in one and could help to further optimise the safety of work in hazardous substances laboratories. Düperthal’s system solution can be used in combination with the certified Drum Station LL storage and removal unit and is therefore an important building block for the green lab. The Drum Station LL has a fire resistance (FR) of 90 minutes and is approved as a safety cabinet for the active storage of hazardous substances. The EN 14470-1 and EN 14727 standards are taken into account, as well as the TRbF 20 Annex L, TRbF 30, BGR 132 and TRBS 2153 regulations.

The first step when removing hazardous substances from the safety cabinet is identification and authorisation by means of magnetic card or barcode system, as only authorised persons may open the cabinet. In the next step the user can then use a number block and modern LED display with the “BlueMode” design to select the medium, e.g. a flammable solvent and set the required quantity. The quantities can be freely selected, regardless of whether shot glass size (20 ml) or a litre mug. After selecting the media and quantity, the keypad is used to activate the pneumatic control of the door opening. A warning signal also informs the user that the automatic door opening has started. The user can now use the integrated tap to fill the selected liquid into their safety container. The system releases the maximum preselected quantity, whereby the user can end the tapping process earlier if they wish. The option of manually activating the pump control provides additional safety. Only after this release has been given is the pump drive supplied with energy and the preselected quantity pre-pumped.

When the filling process has finished the door automatically closes after a defined timespan. An acoustic signal informs the user of the starting opening process so that they are not surprised by it.
