CLEANING AND HANDLING The highly effective alkaline cleaning concentrate Hellmanex III is ideal for use on glass and quartz glass cuvettes, sensitive optical parts and laboratory equipment made of glass, quartz, sapphire and porcelain. It effectively removes dirt and prevents loosened dirt particles from redepositing. After cleaning, the parts can be rinsed without leaving any residue, including UV/Vis activeEXCALIBUR XP
Excalibur XP 12, 20, 25. The Excalibur XP transmission probe has an elastomer-sealed quartz measuring head with a very high transmission. This design enables particularly accurate and reliable measurement results. Basic models of this category are available in diameters 12 mm, 20 mm and 25 mm.

CHECKING WAVELENGTH ACCURACY Checking wavelength accuracy using certified reference materials. To measure wavelength accuracy, the filter reduces the light beam of the spectrophotometer to a greater extent at certain wavelengths ( peaks). Ideally, any reference materials used to determine wavelength accuracy should have narrow, well-defined peaks at a variety of NEUTRAL DENSITY GLASS FILTER Please note, the thickness of the filter is set at the manufacturing so that the specified nominal optical density (values from 0.04 to 3.0 Abs) obtained at 546.1 nm. This results in slightly increasing absorptions at shorter wavelengths. Typical spectrum for Neutral density glass filters F390 - F303 im Bereich von 405 - 800 nm,measured with a

PROCESS ANALYTICS
Process Analytical Technologies (PAT) helps you keep an eye on your production and quality control. The key to success is a precise, robust spectroscopic interface through optical immersion probes or measuring cells. Hellma process probes can be integrated directly into reaction boiler and vessels. Hellma flow cells can be integrateddirectly
DIDYMIUM GLASS FILTER Didymium glass filters are suitable for checking wavelength accuracy (F7W) in the UV-Vis range and photometric accuracy in the UV range. Absorbance behavior in the UV range can be checked at 270 nm, 280 nm, 297 nm, 321 nm, and 342 nm. Filters are routinely set at a thickness that produces a nominal optical density of 0.5 Abs at 342 nm. CERTIFIED REFERENCE MATERIALS Certified UV/Vis-Reference Materials (Calibration Standards) Hellma Analytics reference materials for UV/Vis spectrophotometry meet internationally recognized standards (Ph. Eur., USP, DAB, GLP, DIN ISO 9001, ) and provide the basis for safe and reliable measurement results. Choose from an extensive range of glass filters, liquidfilters and

HELLMA ASIA
Hellma Asia Pte. Ltd. is a subsidiary office of Hellma GmbH & Co KG. Since the inauguration of this regional office in year 2001, we have been supporting our distributors and clients in sales and marketing as well as technical enquiries. As the Asia Pacific headquarter, our coverage encompass Asia and Oceania regions, which includes: Based in CVD ZINC SULFIDE AND CLEARTRAN CVD Ceramics‘ chemically vapor deposited CVD Zinc Sulfide ® is the low cost alternative for infrared windows, domes and optical elements.. With a fracture strength double that of zinc selenide and high hardness, zinc sulfide has been used successfully in many military applications requiring mechanical resistance to hostileenvironments.

CHECKING FOR STRAY LIGHT In USP (42th edition, update Dec. 2019), two possible procedures are described for checking for stray light: Here the stray light filter with a path length of 10 mm is measured against the reference filter (filled with the same solution) with a path length of 5 mm. The stray light value can now be calculated from the absorbance maximum POTASSIUM DICHROMATE LIQUID FILTER Potassium dichromate in perchloric acid is very suitable for checking the photometric accuracy of spectrophotometers. In the UV range, the Potassium dichromate spectrum has characteristic maxima at 257 nm and 350 nm and characteristic minima at 235 nm and 313 nm. The spectrum reaches a plateau at 430 nm, which is used to determine photometric EXCALIBUR HY 25 (3-A) Excalibur HY 25 is a transmission probe with a 3-A sanitary standard fort he efficient control of production processes in hygienicapplications
