Know everything about our services

Medical device manufacturers face increasing demands for fast product release, regulatory compliance, and cost control. At Medistri, we offer one of the most competitive and efficient laboratory services in the Swiss market, enabling you to accelerate time-to-market while maintaining the highest quality standards.

At Medistri, we are committed to advancing healthcare through innovation in laboratory and sterilization services. As regulatory standards evolve and global healthcare companies look for faster, more ethical, and more predictive safety assessments, Medistri supports clients in transitioning from traditional animal testing toward validated in vitro and animal-free methods.

At Medistri, we understand the growing concerns surrounding bisphenols - particularly Bisphenol A (BPA) - in plastics, polymers, and food contact materials. Bisphenols are synthetic compounds used extensively in the production of polycarbonates and epoxy resins. Due to their potential endocrine-disrupting effects, regulatory scrutiny has increased across multiple industries.

1,4-Butanediol diglycidyl ether (BDDE, CAS No. 2425-79-8) is a chemical compound widely used as a crosslinking agent in the manufacture of hyaluronic acid (HA)-based dermal fillers. Its primary function is to enhance the durability and longevity of these products by binding to HA molecules, increasing their resistance to enzymatic degradation. Given its extensive use in medical and cosmetic applications, ensuring the safety and quality of BDDE-crosslinked products is essential. A key aspect of this assurance lies in the accurate detection and quantification of residual BDDE in HA-based dermal fillers.

Medistri is proud to expand our comprehensive testing capabilities to include specialized food contact material testing - a critical requirement for manufacturers across the food and packaging industries. Drawing on our established expertise in laboratory testing and quality assurance, we've recently developed this new service to address growing market needs.

Medical Device and Pharmaceutical companies must ensure their products are safe for use and compliant with international regulations. Extractables and Leachables (E&L) testing plays a key role in this effort, as outlined in standards such as ISO 10993 and the United States Pharmacopeia (USP). At Medistri, we provide comprehensive E&L analyses to support product development, regulatory submissions, and patient safety.

We are pleased to announce that Medistri has expanded its scope of services under the Swiss Accreditation Service (SAS). Since its founding in 2006, Medistri has grown into a leading provider of contract sterilization and laboratory services for healthcare companies, becoming a trusted partner for businesses in the pharmaceutical, medical device, and biotechnology sectors.

At Medistri, we recognize the critical importance of cytotoxicity testing in the development and approval of medical devices. These tests are not merely regulatory checkboxes but are fundamental to ensure that materials used in medical devices are biocompatible and safe for direct human contact. This blog delves into the sophisticated methodologies we employ and the standards we adhere to, ensuring the highest level of safety and compliance.

Ensuring patient safety is paramount when sterilizing medical devices. Among sterilization methods, ethylene oxide (EO) is widely used due to its compatibility with a broad range of materials. However, residuals such as ethylene oxide, ethylene chlorohydrin (ECH), and ethylene glycol (EG) can remain on the devices post-sterilization. These residues must be minimized to prevent harm during product use.

MTT Assay is a colorimetric assay that measures the metabolic activity of cells as an indicator of their viability. By leveraging the cell's natural enzymatic processes, this assay transforms a yellow tetrazolium salt (MTT) into insoluble purple formazan crystals. These crystals only form in cells with active metabolism, offering a direct correlation between formazan production and the number of living cells.
