ABOUT US

    

Extract Technology, formerly known as Walker Barrier Systems in North and South America, is a leading supplier of containment and aseptic systems for the pharmaceutical, biotech and nuclear industries. Our product line includes pharmaceutical isolators for containment of potent compounds and aseptic processing applications; downflow booths for operator protection from breathable dusts; and a full range of brand pack-off systems to safely offload powder products into drums or IBCs. Restricted Access Barrier Systems (RABS) are also available, providing unidirectional airflow and limited operator access during the pharmaceutical manufacturing process. We will custom design equipment to best suit your process or integrated equipment needs.

Our Mobile Clean Room (MCR) provides fast, flexible clean room manufacturing space without the considerable time and costs associated with more traditional clean room options. The “MCR” can be designed with ISO 7 or ISO 8, BSL1 and BSL2+ environments for pharmaceutical and biotech applications, or ISO 5 and ISO 6 environments for semiconductor applications. The MCR is delivered fully assembled to your facility ready to use. Extended-width units are available to increase manufacturing space.

Downflow Containment Booths & Glassware Booths Downflow Containment Booths & Glassware Booths

Downflow Containment Booths are used extensively in the pharmaceutical industry to safeguard operators against harmful dusts generated during many manual powder handling operations. Clean air from the ceiling plenum is distributed evenly across the whole of the work area pushing any respirable dust downwards and away from the operators breathing zone.

Glove Tester For Isolators Glove Tester For Isolators

The glove tester can test gloves in place prior to decontamination or isolator use for pharmaceuticals.

Nuclear Glovebox Nuclear Glovebox

Many of our nuclear glovebox projects are design – build projects which involve process and machine integration. In fact many times you will here Walker Barrier Systems ask, “Teach me your process; I have to know what you are trying to do inside your glovebox”. Some of design services we offer:
