Glass cuvettes

Ideal for storing up to 16 cuvettes with 10 mm width. Two-tier arrangement of the cuvette rows ensures clarity.

• Numbered positions
• Autoclavable at 121 °C

LLG-Cuvettes are most frequently used in analytical laboratories.

They have two clear windows, two side walls and are available as optical glass or quartz variants. The walls and the base are polished inside and frosted outside. The thickness of the windows and the base is 1.25 mm. The overall height of standard type cells is 45 mm or 48 mm for those fitted with a stopper. Each cuvette is supplied with a PTFE lid.

High precision standard cells for routine analysis. Suitable for most spectral photometers, using rectangular cells. Available with cover or with stopper for a liquid-tight seal. Cover and stopper made of PTFE.

Glass types
Type G: Optical glass, 334 to 2500 nm
Type SOG: Special optical glass, 320 to 2500 nm
Type Q: Spectrosil^® Far UV Quartz glass, 190 to 2700 nm

Ideal for enzymatic determinations, since the very thin walls enable rapid and uniform equilibration.

Properties:

• Manufactured from crystal clear polystyrene
• Minimal light scatter
• High transmission rate
• Applicable wavelength range from 340 to 900 nm

To maintain constant good measurement results, a regular review of the accuracy of the spectrophotometer is required. With the use of certified reference materials from Hellma Analytics, you make sure that your equipment qualifications meet the requirements of the pharmacopoeias and fulfill your internal quality requirements, at the same time you reach the international comparability of your measurement results. The certified reference materials (calibration standards) of the DIN EN ISO 17025 accredited Hellma Analytics calibration laboratory are traceable to the primary standards of NIST (National Institute of Standards and Technology) and meet the requirements of the major pharmacopoeias (e.g. EP, DAB, USP).
Your benefits:
