ALL-QUARTZ FLOW-THROUGH CUVETTE

Hellma 176.762-QS All Quartz Flow-Through Cell with Two Optical Path Lengths, Quartz SUPRASIL Glass, 200-2500 nm, 50μl, 3 x 1.5 mm Path Lengths, 15 mm Centre Height, 1/Pk

Product Number: 176-762-15-40

3 IN 1 - ALL IN ONE SINGLE CUVETTE

  • ABSORBANCE
  • FLUORESCENCE
  • 2 OPTICAL PATH LENGTHS

ALL-QUARTZ FLOW-THROUGH CUVETTE

  • Flexible in application
  • 2 optical path lengths in one single cuvette
  • Excellent reproducibility of measurement results
  • Fluorescence measurement possible for each path length
  • High temperature and chemical resistance because of all-quartz construction

Ideally suited for tablet dissolution analysis (TDA) and flow-through spectroscopic analysis

The all-quartz flow-through cuvette is a high-precision cell for applications in spectroscopy. New technology enables the positioning of precise internal threads into the quartz glass. Tubes can now be connected very easily and securely directly to the cuvette. The second path length is available by simply turning the cuvette through 90° – all tubes remain screwed in place.

Time consuming changing of the cuvette is no longer necessary. Two different path lengths have a beneficial effect to the costs and the application. Furthermore, it is possible to measure the fluorescence with each optical path length – another benefit.

Clear advantages due to the innovative all- quartz design

  • No liquid leakage, monolithic quartz glass construction prevents this by design
  • Suitable for high and low temperatures
  • Fully autoclavable
  • Secure tube connection is ensured due to the innovative quartz glass internal threads

Special features for TDA applications:

  • Second path length can be set without the time consuming replacement of the cuvette and the disconnecting and reconnection of the tubing.
  • Everything in sight: Red point mark for the quick detection of the path length position

Material Codes

Material Material Code Wavelength Refractive Index nd at 588 nm Type of spectrophotometer
 
Optical glass OG 360 nm - 2500 nm 1,523 for the visible range
OG indicates that "Optical Glass" is used for the window. Here we use a colorless highly transparent crown glass in the form of drawn panes with fire-polished surfaces. The quality of the surfaces is so high that the components can be fused using the Hellma process without further grinding and polishing. An empty cell made of optical glass will give a transmission of more than 80 % over a spectral range from 360 nm to 2500 nm.
 
Borofloat®
Borosilicate Glass
BF 330 nm - 2500 nm 1,473 for the visible range
BF indicates the cells entirely made from borosilicate glass, the composition and properties of which are laid down by an international standard. This type of glass possesses a high chemical resistance and a low thermal expansion coefficient making it particularly suitable for its use as laboratory glassware. For the windows of these cells we use a borosilicate glass manufactured using the float process. An empty cell made from this material has a transmission of greater than 80 % at a spectral range of between 330 nm and 2500 nm.
 
Special optical glass OS 320 nm - 2500 nm 1,523 for the visible range
OS indicates that “Special Optical Glass” is used for the window. This crown glass, specifically developed for Hellma, is made from exceptionally pure raw materials and gives improved transmission in the near ultraviolet range. An empty cell will give a transmission of more than    80 % over a spectral range from 320 nm to 2500 nm.
 
HOQ 310H
Quartz Glass
UV 260 nm - 2500 nm 1,458 for the UV range
UV indicates that “Quartz Glass” of highest purity and homogeneity is used for the window. These specially selected quartz glasses ensure transmission values of more than 80 % for a spectral range from 260 nm to 2500 nm for an empty cell.
 
Quartz SUPRASIL®
Quartz Glass High Performance
QS 200 nm - 2500 nm 1,458 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.
 
Quartz SUPRASIL® 300
Quartz Glass Extended Range
QX 200 nm - 3500 nm 1,458 for the NIR range
QX indicates that “Quartz Glass Extended Range” of highest purity and homogeneity and free from OH absorption is used for the window. It is suitable for applications in the near infrared range up to approximately 4000 nm. We use specially selected quartz glasses which ensure transmission values of more than 82 % for a spectral range from 200 nm to 3500 nm for an empty cell.

 

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 daiy work. On request, we are able to produce custom models designed for specific areas of application.
