Esco Stainless Steel Weighing Chamber at Beximco Pharmaceuticals Ltd.
Esco Pharma completes Esco Groups’ Life Sciences expertise in Biocontainment by providing cGMP Flowhoods running on HMI/PLCs with 21 Cfr part 11 compliance designed as Class @ A2 Biological Safety Cabinets. As an option these can be tested during IOQ with KI Discus Containment testing to EN 12469 standards. In this application our flowhood was designed with a downflow velocity of 0.45 m/s and cooling coils to maintain temperature at 21ËšC ±2Ëš. In addition, a dehumidification unit maintains <20% RH for weighing and dispensing of hygroscopic powders.
