Hellma GmbH & Co. KG is the global market leader in the manufacture of high-precision optical components and integrated solutions for molecular spectroscopy and process analytics. Founded in 1922 in Müllheim, Germany, by Karl and Paul Mayer, the company revolutionized the field of analytical chemistry by developing the first commercially viable precision cuvettes. Hellma’s mission is centered on "The Fine Art of Precision," ensuring that every optical component—whether made of high-purity quartz glass, optical glass, or calcium fluoride—delivers absolute accuracy for scientific research. With over a century of glass-working expertise, the brand has expanded into specialized fields including flow cytometry and fiber-optic process monitoring. Today, Hellma GmbH & Co. KG remains a family-owned enterprise, providing the essential "heart" of spectrophotometers used in leading pharmaceutical, environmental, and industrial laboratories worldwide.
The Hellma range at LabFriend features professional analytical measurement solutions, headlined by their world-renowned absorption and fluorescence cuvettes. These cells are manufactured with ultra-tight pathlength tolerances to ensure reproducible results in UV/Vis/NIR spectroscopy. For micro-volume research, the brand provides the innovative life science TrayCell 2.0, allowing for the analysis of DNA and proteins in samples as small as 0.5 µL. Their portfolio also includes essential general laboratory aids, featuring the Hellmanex III cleaning concentrate, specifically formulated for the residue-free maintenance of sensitive optical surfaces. To support regulatory compliance, Hellma offers a comprehensive range of certified reference materials and calibration standards from their DAkkS-accredited laboratory. By choosing Hellma through LabFriend, you benefit from competitive pricing and fast shipping on German-engineered optics designed for ultimate analytical integrity.
Why Choose Hellma Analytics for Your Laboratory?
- World-Leading Precision: Hellma cuvettes are manufactured with a surface flatness of 1 µm and pathlength tolerances as tight as ± 0.003 mm, setting the global benchmark for accuracy.
- Premium Material Quality: Utilizes high-performance Suprasil® quartz and specialized optical glasses to ensure maximum light transmission across the entire spectral range (200 nm to 3500 nm).
- Innovative Patented Technology: Solutions like the 3-in-1 all-quartz flow cells and TrayCell 2.0 offer unique ways to handle low volumes and high-pressure process monitoring.
- Certified Traceability: As an ISO 17025 accredited laboratory, Hellma provides certified reference standards that are traceable to primary NIST standards for instrument qualification.
- Chemical & Thermal Robustness: Their proprietary thermal bonding process (fusion) creates an "all-glass" structure without adhesives, ensuring cells are resistant to aggressive solvents and high temperatures.
Frequently Asked Questions
1. What is the difference between QS, OS, and OG material codes?
QS stands for Suprasil® Quartz (200-2500nm), ideal for UV work. OS refers to Special Optical Glass (320-2500nm) for the visible range, and OG is standard Optical Glass (360-2500nm) for basic colorimetric tasks.
2. How should I clean my Hellma cuvettes?
For best results, use Hellmanex III cleaning concentrate. It is designed to remove proteins, grease, and silicones without damaging the polished optical windows or the structural integrity of the cell.
3. Can Hellma cuvettes be used in all spectrophotometer brands?
Yes, Hellma manufactures cells according to international standard dimensions (12.5 x 12.5 mm), making them compatible with almost all benchtop UV/Vis spectrophotometers on the market.
4. Why is a "matched pair" of cuvettes important?
Matched pairs are individually tested to ensure they have nearly identical transmission characteristics. This is critical for dual-beam spectrophotometers to eliminate differences between the sample and reference cells.
