Absorption Cells

Hellma 114-QS Semi-micro Absorption Cell with stopper for UV spectrophotometers, Quartz SUPRASIL® Glass High Performance 200nm-2500nm, 700μl, 5mm Light Path, 45 x 12.5 x 7.5 mm, 1/Pk

Product Number: 114-5-40

Hellma Analytics produces a wide range of cuvettes for use in spectroscopy and cytometry with optical path lengths spanning 0.01 mm to 100 mm and above. Thanks to their stability, maximum precision and reliability when used for absorbance and fluorescence measurements, Hellma cuvettes work exceptionally well in a wide range of areas in the lab. With a surface flatness of 1 μm, our quartz windows set a benchmark in cuvette production.

What’s more, the function-optimized design with beveled edges and corners protects against the risk of damage caused by splitting and assists users in their daily work. On request, we are able to produce custom models designed for specific areas of application.

QS - Quartz Glass High Performance - for the UV range

QS indicates that “Quartz Glass High Performance” of the highest purity and homogeneity is used for the window. Because it is made from a silicon compound, it is also called synthetic quartz glass. We use specially selected quartz glasses which ensure transmission values of more than 82 % for a spectral range of 200 nm to 2500 nm for an empty cell.

Polarimetric checking of cuvettes

Cuvettes with an inside width greater than 5 mm can be polarimetrically checked on request. They are marked with a “P” and delivered with a test certificate confirming that the rotation of the polarization plane does not exceed
0.01 degrees.

ADVANTAGES

• Extremely high parallelism of the windows with a maximum tolerance of ± 0.01 mm
• Exceptional optical path length accuracy down to 0.003 mm (3 μm) for high dimensional accuracy and reproducible measurements results
• Unique surface flatness of the optical windows of 0.001 mm (1 μm)
• Very high temperature stability and chemical resistance due to thermal bonding of individual components (effectively monolithic)
• Guaranteed transmission of at least 82% from 200 nm to 3500 nm depending on the material
