Gelman IsoGuard ISO Series Type 1 Positive Pressure (Recirculating) Pharmaceutical Isolators are effective laboratory aids in obtaining the optimum control over product quality and meet the needs of pharmacy applications involving compounding and dispensing of non-hazardous pharmaceuticals or drugs, preparation of IV solutions and eyedrops, TPN (Total Parenteral Nutrition), ampoule filling, quality controls and pharmacy routines that require absolute sterility.
The IsoGuard ISO Series Positive Pressure (Recirculating) Isolators are commonly used for sterility testing of pharmaceutical products before release to market for distribution and use.


The IsoGuard ISO Series Type 1 Positive Pressure (Recirculating) Pharmaceutical Isolator offers a contained, positive pressure work zone with a unidirectional HEPA-filtered airflow to provide aseptic conditions within the work area for product protection.
An effective physical barrier between the work area and the environment is maintained by an air-tight viewing window.
The isolator work zone are maintained at a positive pressure to the room with the work area pressure slightly more positive than the transfer chambers.
Operations in the isolator are carried out through rubber gloves attached to large diameter glove ports, ergonomically located for greater arms movement.
The viewing window with the glove ports attached, is hinged along the top and may be fully opened for cleaning, loading and unloading of auxiliary equipment.
Independent D-Type Dual HEPA-filtered entry & exit transfer chambers, fitted to each side of the isolator allow operator to introduce or remove items from the work area while maintaining the internal aseptic conditions.
Ambient air is drawn in through an easily accessible prefilter and inlet HEPA filter on top of the isolator and is introduced to the work area through a supply HEPA filter.
HEPA-filtered vertical airflow free from airborne contaminants is projected downwards over the work surface to create an ultra-clean work area for aseptic work and product protection.
The downflow air is largely recirculated back to the work area through the supply HEPA filter on top of the work zone
The remaining downflow air is discharged to the laboratory via the dual HEPA-filtered transfer chambers.
