Containment Surrounding the Sample Port of a Filter/Dryer
A 1 sq.m. Rosenmund filter installed through a floor. The sample port is approximately 1 foot below ceiling level. A glovebag is mounted onto the sample port. The glovebag allows the port to be rodded out before a sample drogue is admitted. Sufficient space is provided to allow the drogue to access the center of the filter cloth.
Glovebag for Adding Materials to a Vessel
The sample shown is a small enclosure used for safely adding materials, e.g. seed material or reagents, to a process during operation. The bottom of the glovebag has a tri-clover fitting for attachment to the vessel nozzle. The entire enclosure can be purged before the vessel valve is opened.
A Package-to-Weight Enclosure
Product travels from the overhead hopper to the liner below the glovebag. A small container of product from the first drop is used to top up the liner to specification. Weight parity (52 Kg +/- 13 g.) with a finishing site was achieved over several years of production.
This small room enclosure was used to safely transfer rework material to a process. Such portable enclosures are highly adaptable for single or routine usage.
Processing Ticket Containment
A simple enclosure for filling out a processing ticket (or any smaller items, e.g stopwatch, in a contaminated workplace. The ticket is placed inside the glovebag before passing into the work area. After use it is recovered when the operator de-gowns. The frame is reusable.
The enclosure is installed above the charge nozzle. Seed is added through a pass-through port designed into the glovebag. This system allows several different addition methods -in this case a T-nozzle approach to allow for a washdown.
