MK Versuchsanlagen GmbH & Co. KG, based in Mücke-Merlau (Hesse, Germany), has specialized since 1988 in metal-free laboratory systems, cleanroom technology, and automated Glove Testing Systems.

The company develops and manufactures customized solutions for the pharmaceutical, life sciences, semiconductor, and optics industries – from contamination-free cleanrooms made from metal-free materials to Glove Integrity Test Systems (GITS®), as well as custom software and Industry 4.0 electronics. Production is carried out entirely in-house, certified according to ISO 9001:2015 and at the highest quality level.

MK Versuchsanlagen is a family-owned company based in Mücke-Merlau (Hesse, Germany), founded in 1988 by Michael Keil. As managing director, he continues to shape the strategic direction and technological innovation of the company.

The management team combines deep technical expertise, years of industry experience, and a strong vision for quality, innovation, and customer proximity.

The company culture emphasizes personal responsibility, close cooperation with customers worldwide, and a strong focus on sustainable manufacturing “Made in Germany.”

All development, design, software and hardware engineering, and manufacturing are carried out by a dedicated team at the company’s headquarters in Central Hesse.

Metal-free systems are laboratory or cleanroom installations built entirely without metallic components. Instead of stainless steel or aluminum, they use special materials such as chemically resistant fiberglass-reinforced plastic (GRP).

Avoiding metals eliminates even the smallest contaminations – a critical factor in areas where the highest purity is required, for example:

• In ultra-trace and trace analysis (e.g., geochemical research)
• In the production or testing of pharmaceutical ingredients
• In semiconductor, optics, or environmental research

Metal-free cleanrooms ensure reliable analysis results and protect sensitive samples and processes from metal contamination. In addition, corrosion is prevented through the exclusive use of chemical-resistant materials.

MK Versuchsanlagen specializes in the development of such systems and is one of the leading providers in this field.

Our mobile laboratory containers – MK Mobile Labs – are designed for flexible use in virtually any location. Whether on the roof of a research institute, aboard an expedition ship, or in remote regions: they can be quickly deployed, require minimal construction effort, and are usually not subject to the permitting requirements of traditional buildings.

Thanks to their modular design, metal-free construction, and customizable technology, they are ideal for projects with changing locations, limited space, or special safety requirements.

We design every cleanroom as a customized solution – precisely tailored to your technical, spatial, and process-specific needs.

During a structured planning process, all relevant factors are clarified in advance: from intended use and cleanroom classification to specific workflows and regulatory requirements.

All components are manufactured in-house, ensuring maximum flexibility and quality.

Through close collaboration throughout the entire project – from consultation and design to installation and commissioning – we deliver a cleanroom that is technically, functionally, and economically optimized for your application.

Laminar airflow – either vertical or horizontal – flushes airborne particles out of the workspace, ensuring an exceptionally clean environment.

Turbulence is avoided, and although the airflow velocity is low, high air exchange rates are still possible.

The incoming air is filtered using HEPA or ULPA filters to remove even the smallest particles before entering the critical work area.

Additionally, laminar flow helps safely and efficiently remove heat loads and chemical acid vapors from the workspace, without endangering users.

An automated Glove Testing System like our MK Glove Integrity Test System (GITS®) offers a fast, safe, and fully documented method for testing the integrity of gloves used in isolators or RABS (Restricted Access Barrier Systems) – without interrupting production (in-situ).

Your benefits at a glance:

• Time-saving: Simultaneous testing of all gloves – test times from 5 minutes (depending on material and glove size)
• GMP & Annex 1 compliant: Meets EU GMP Annex 1, FDA 21 CFR Part 11, and GAMP 5 requirements
• Traceability: Automated documentation, data transfer, and reports – integrable into your Contamination Control Strategy (CCS)
• Wireless operation: No disruptive cables, easy cleaning, compatible with H₂O₂ / VHP decontamination
• Smart features: RFID-based port and glove recognition and GLCS® for glove lifecycle monitoring and defect detection
• Flexible integration: Operates as a standalone system or can be fully integrated into existing setups

GITS® is a reliable Glove Testing System that improves efficiency while ensuring maximum safety.

Glove Testing Devices ensure the tightness and integrity of gloves used in isolators and RABS systems. These gloves form a critical barrier between product and operator – even minor leaks can lead to contamination or batch failure.

An automated Testing System enables:

• Reliable integrity testing before, during, or after production
• Compliance with regulatory requirements (e.g., EU GMP Annex 1)
• Complete documentation and traceability
• Safe pharmaceutical manufacturing without compromising product or personnel safety

In short: Glove Testers secure your processes, protect your products, and help maintain the highest quality standards.

Glove integrity is typically tested in cleanroom or isolator environments using automated pressure decay tests.

The glove is inflated with air for a defined period, and the system monitors how fast the pressure drops – which can indicate leaks such as microcracks or pinholes.

Modern systems like the MK Glove Integrity Test System (GITS®) perform these tests automatically, wirelessly, and software-assisted, including:

• RFID-based identification of glove and port
• Simultaneous testing of multiple gloves (e.g., on an isolator)
• Automated documentation and evaluation of all results
• Full compliance with GMP and Annex 1

This ensures that only compliant gloves are used in production – for maximum product safety and process reliability.

The Transfer System Tester (TST) is a specialized device for integrity testing of Rapid Transfer Ports (RTP), alpha ports, and beta containers.

It enables fast, automated testing via pressure decay and reliably detects even the smallest leaks.

As an RTP tester, the TST can be flexibly adapted to various RTP containers and port systems.

Thanks to integration options with existing systems such as GITS®4 or GLCS®, and features like WLAN and RFID recognition, the TST offers maximum process security, full traceability, and supports compliance with regulatory standards such as EU GMP Annex 1, 21 CFR Part 11, and GAMP 5 – all with minimal impact on production workflows.

The Glove Life Cycle System (GLCS®) enables complete traceability of glove usage within cleanrooms.

Using RFID technology, the software automatically documents storage, sterilization, aging, and cleaning of each glove.

If predefined limits are exceeded, the system issues warnings or blocks testing automatically.

This ensures that unsafe gloves are reliably identified, enabling compliant and safe glove use in accordance with GMP standards – while also highlighting early wear and reducing unnecessary glove consumption, thus supporting both process safety and environmental sustainability.

The Analysis & Reporting Tool (ART) is a centralized platform for generating and evaluating reports from GITS® and GLCS®.

It produces machine- and port-specific reports, audit trails, and freely configurable evaluations.

With centralized data collection, trends can be identified, weaknesses analyzed, and informed decisions made.

ART is 21 CFR Part 11-compliant, fully network-capable, and supports both electronic and automated printouts – ideal for audits and quality assurance documentation.
