FAQ – Frequently Asked Questions

The portfolio includes:

  • Sterility test isolators for aseptic testing 
  • Custom isolators with integrated process technology 
  • Systems with H₂O₂ decontamination (VHP and aHP)
  • Weighing isolators

In addition, HMI offers precisely matched accessories for the safe operation of isolators, including gloves, glove ports and glove testers for leak testing. All components are optimally coordinated and individually designed for the respective process.

Isolators are closed barrier systems that separate the product, the operator and the environment from one another. They enable sterile or highly secure processes, especially when handling highly potent or toxic substances. Depending on the pressure level, a distinction is made between operator protection and product protection. 

Positive pressure = product protection

Negative pressure = operator protection

Custom isolator solutions from HMI are used when standard units reach their limits – whether due to space constraints or complex process steps. The advantages of a tailor-made solution are:

  • Seamless process integration: The isolator is designed precisely around your process technology, whether as a stand-alone unit or as part of an interlinked line.
  • Optimal ergonomics: An individual design and precisely positioned glove ports significantly improve handling for the operator.
  • Maximum safety: We adapt the containment level (up to OEB 5) and the accessories (testing systems, sensors) precisely to your toxic or aseptic requirements.

HMI develops solutions where the market has no standard answers. 

Glove ports form the critical physical barrier between the operator and highly active substances in isolators. To ensure GMP-compliant containment safety (ISO 14644), isolator and RABS gloves must be tested for leak-tightness at regular intervals. HMI offers two systems for this purpose:

  • AGT (Analog Glove Tester): The purely mechanical solution with an analog pressure gauge.
    • Advantages: Very robust, easy to use, low-maintenance and low operating costs.
  • DGT (Digital Glove Tester): The smart, automated solution.
    • Advantages: Wireless testing, precise digital evaluation, reliable detection of even the smallest leaks and easy integration into modern documentation systems. Ideal for highly regulated environments.

We will be happy to work with you to determine which testing system best meets your regulatory requirements.

The STC sterility test isolator from HMI creates an aseptic environment of cleanroom Grade A (ISO 5) through:

  • Controlled laminar airflow: Protection against cross-contamination.
  • Integrated H₂O₂ decontamination: Fast, reproducible decontamination cycles.
  • Closed design: Maximum separation of operator and product.

The system thus meets all requirements of EU-GMP Annex 1 for validatable sterility testing.
