We offer you a full line of optical cells made from quartz and glass. If you see transmission start at 190 nm this is a UV quartz cuvette. Observation of microorganisms is an…, The analytical results you communicate can have far-reaching consequences and can form the basis for taking decision on safety of use of commercial products, foods…, I am sure you are also using a hand sanitizer and sometimes wonder if it is really effective and even wondered how you can check…, Your email address will not be published. Disposable cuvettes are preferred to prevent carry over of samples. Apart from these characteristics, there is another benefit of quartz, i.e., the highest temperature resistance. Which Cuvette Is the Right One? transparent to the wavelength of light required for the purpose. Read about company. 3 Easy Simple Tests. Quartz and Glass Cuvettes ... Cuvette price is shown in the pricing drop-down menu to the far right. Style 9B Semi-micro Self Masking cuvette Black quartz blocks off-axis rays that lead to stray light and lower linearity” data-description=”” itemprop=”contentUrl”> We are always hard work to produce the Quartz and Glass Cuvettes for the Spectrometer, Colorimeter, Spectrophotometer, Lovibond Tintometer, Fluorometer and other instruments. However, it is even more fragile than glass and the cuvettes need to be handled with greater care. Again depending on your application will determine which one of the above are best. £2.29. Categories: Product Information. What we do here at FireflySci is we mark all the different materials directly on the cuvette. How to Identify a Glass Cuvette. For example, plastic may not be efficient for UV-range experiments, but it is a cost-effective alternative for all the visible light studies. If the transmission starts at 340 nm this is a glass cuvette. When organic solvents are used, glass or quartz are preferable because the corvettes display higher resistance when compared to others made from plastic. IR Quartz glass IR, I 250~3500nm 2730nmAbout82% 2730nmMAX0.5% ES Quartz glass UV, Q 190~2500nm 200nmAbout82% 200nmMAX0.5% UV Quartz glass UV, Q 220~2500nm 220nmAbout82% 220nmMAX0.5% [ES Quartz is a slightly better grade of quartz than UV Quartz and offers superior trans-mission in the lower nm range. Cuvettes are small rectangular glass or quartz containers. Usually, a container of precise dimensions, i.e., 10mm path length, gets used here. In general, quartz and glass cuvettes display greater transparency and accuracy of measurement, and they can be re-used many times over plastic cuvettes. Feeling limited by our stock cuvette designs? Then comes the optical glass cuvette, and finally, the quartz cuvette. Each of these materials has their strengths and weaknesses. In case you don’t give importance to these factors about cuvette used in UV spectroscopy, you will end up creating trouble in the absorbance studies, and the obtained results won’t be accurate. Macro, semi-micro and micro sizes are all available. Besides the in-stock UV quartz cuvettes listed below, we do many custom orders. It also comes in path lengths up to 100mm. Standard Rectangular cuvette with stopper Same cuvette as 1-Q-10 but with a stopper. Quartz and glass cuvettes are used when organic solvents are involved, which have higher resistance compared to plastic types.

Researcher:  These cuvettes seem very old, so maybe it wore off. At first sight all such materials appear to be perfectly transparent and fit for all types of absorbance studies.However, each material has unique light absorbing properties and it is important to know about such optical characteristic properties before making your selection of the cuvette material. UV Quartz. These are called cuvette spectrophotometers. We are always hard work to produce the Quartz and Glass Cuvettes for the Spectrometer, Colorimeter, Spectrophotometer, Lovibond Tintometer, Fluorometer and other instruments.

Concerning your issue about the kind of cuvette that should be used in the range of 200-300 nm wavelength. Absorbance measurements made below 200 nm should be conducted with oxygen free nitrogen purging of sample compartment. Materials include Spectrosil quartz (170 to 2200nm), Infrasil quartz (220 – 3800nm), Glass and special optical glass. Standard Rectangular cuvette with stopper Same cuvette as 1-Q-10 but with a stopper. Our Quartz Cuvette … However, Common laboratory absorption studies involve liquids – either as pure solvents or solutions of light absorbing compounds in transparent solvents. So one may easily get confused about which alternative to use. Optical Glass or Pyrex Glass. The earlier article titled Proper care and handling of UV – Vis absorption measurement cells highlights the precautions required in careful handling of cells and on ensuring a high degree of accuracy of your measurements.
