Laboratory Equipment
Our comprehensive range of laboratory equipment is designed to meet the rigorous demands of analytical and research laboratories. We offer high-quality standard solutions with certified concentrations, ideal for calibration, quality control, and routine analysis. Each solution is traceable to international standards and delivered with a detailed certificate of analysis (CoA) for full documentation and reliability.

To complement your workflow, we provide a wide selection of crimp caps, available in various sizes and materials to match all common vial types. Whether aluminum, magnetic, or septum-sealed, our caps ensure a secure seal for optimal sample integrity.

Additionally, our assortment of laboratory accessories includes vial racks, crimpers and decrimpers (manual and electronic), septa, and storage containers—everything needed to streamline your sample preparation and analysis processes.

All products are manufactured to the highest quality standards and are compatible with major laboratory systems and instruments.
