Schematic barrier isolators112Schematic manufacture two types of polished 316 stainless steel sieves; safety screening sieves and grading sieves.

Safety screening sieving is done to ensure the correct product quality of powders, where the objective is to remove any over-sized contamination from the powder.

Grade sieving is done to ensure the correct sizing of powders or granules. In the pharmaceutical sector, primary and intermediates must be sieved to remove oversize and under-size particles to ensure a correct particle size distribution ready for granulation and subsequent tablet pressing.

For hazardous powder processing, our laboratory sieves are designed for safe and comfortable operator operation within our flexible or rigid barrier isolator systems.
