Sampling and Dispensing Booth

Care Equipments - Clean Room Equipments Manufacturer

Sampling and Dispensing booth is a kind of laminar flow filtration cabin that is employed in dispensing, sampling, and weighing powders and chemicals in pharma, biotech, and chemical industries. Such units work on the reverse laminar flow working principle and provide protection to operators, products/samples, and the surrounding environment. Dispensing booth is usually made of stainless steel and equipped with three-stage filtration (10µ Pre-filter, 3µ Intermediate, and 0.3µ HEPA Filter) with the help of a motor blower assembly. In order to measure the pressure of the HEPA filter, Differential Pressure gauges are fitted. Pre-filters are washable. It is also known as Reverse Laminar Airflow Unit.
