Hellma Analytics - Quality for Photonics and Analytics

Hellma is a well-known company in the development, production and distribution of precision products made of glass, quartz and crystalline materials. With over 100 years of experience and a wide range of products and services, Hellma is an important partner for companies in the fields of life sciences, photonics and analytics. The product range of Hellma includes cuvettes, liquid filters and cylinder optics.

Production facilities in Germany and the USA

The highly specialised production facilities of Hellma are mainly located in Germany. In addition, Hellma also has a manufacturing site in the USA. The company also operates worldwide, with 8 sales subsidiaries in England, France, Switzerland, Canada, USA, BeNeLux, Italy and Asia to strengthen its global presence and customer proximity.

Extensive product range for a variety of different applications

Hellma manufactures a wide range of glass and quartz products for optical applications. Part of the product range are, for example, measuring cells for spectroscopic analyses in the UV/Vis and NIR range. In addition, Hellma produces optical components such as windows, lenses and prisms that are used in photonics. With these products and many other customised solutions, Hellma offers its customers a wide range of precision products that are optimally tailored to the needs of a wide variety of applications.

Important component for analytics: Cuvettes from Hellma

Analytics Cuvettes are used in chromatography to measure the concentration of analytes in liquid samples. They are also frequently used in spectroscopy, especially in UV-Vis spectroscopy, but also in fluorescence spectroscopy, Raman spectroscopy and infrared spectroscopy. These rectangular or square vessels have an individual layer thickness and are available in different sizes. The optical properties of the cuvette are crucial, as they minimise the influence of the sample matrix and enable accurate analysis. In order to perform precise measurements, the cuvettes must have a high optical transparency. Therefore, the material often used is quartz glass or optical glass, which has minimal absorption of light in the UV and visible range. Hellma offers a wide range of cuvettes for UV/Vis absorption and fluorescence measurements in different materials and with variable layer thickness, which are adapted to the requirements of spectroscopic analytics. All Hellma cuvettes are thermally bonded and not glued together. This prevents the cuvette from leaking or falling apart at high temperatures or in contact with chemicals and consequently contaminating the measuring instrument. Hellma cuvettes are known for their precision and are particularly pleasant to handle. Due to the specially machined edges, the risk of chipping is reduced. The company has been manufacturing cuvettes for more than 95 years and attaches great importance to the continuous development of its processes.

The correct cleaning of cuvettes for optimal measurement results

A cuvette is a vessel in which photometric measurements are taken on liquid or gaseous samples. In order not to falsify these measurements, the cleanliness of the cuvette used is of particular importance. The cleaning of cuvettes is very important, as even minor impurities can significantly affect the measurement accuracy. Deposits, scratches or turbidity on the surface of the cuvette can impair the optical quality of the cuvette and thus lead to an inaccurate measurement result. In addition, residues of sample material can settle in the cuvettes and lead to errors during the next measurement. Careful cleaning therefore ensures the accuracy and reliability of the measurements, which is crucial in many applications, such as environmental analysis, food analysis or pharmaceutical analysis. Hellma not only offers a wide range of different cuvettes, but also an efficient solution for cleaning them: The Hellmanex III special cleaning concentrate enables residue-free removal of even stubborn contamination while protecting the cuvette as much as possible.
