Product Introduction

The sterility test isolator separates test samples and media from operators and the surrounding laboratory. One or two glove-access work chambers can support membrane filtration, direct inoculation or compatible rapid methods. Samples enter through a bio-decontamination hatch or rapid transfer port, and liquid and solid waste leave through dedicated closed routes. The chamber uses filtered airflow, welded stainless surfaces and pressure monitoring to maintain the selected test environment and reduce false-positive contamination risk.

Key Features

Glove positions are spaced for simultaneous sample opening and test manipulation.

A dedicated transfer hatch separates load preparation from the main test chamber.

Separate liquid and solid waste interfaces prevent waste crossing the clean sample route.

A common control system monitors pressure, airflow and optional bio-decontamination cycles.

Radiused stainless interiors keep membrane-filtration equipment accessible for cleaning.

Customer Product Concerns

Sterility testing needs both contamination prevention and a workflow that keeps sample entry, test manipulation and waste removal from crossing each other.

Room-borne contamination creates false-positive test results.A closed filtered chamber and controlled transfer path isolate the test from the laboratory.

Two operators cannot reach the same test setup efficiently.Paired glove positions and a long work zone support parallel manipulation.

Waste removal crosses the incoming sample path.Dedicated liquid and solid waste ports separate egress from sample loading.

Test equipment creates inaccessible surfaces.Removable supports and radiused internal geometry preserve cleaning access.
