For the purpose of photometric analyses of liquid samples, the solution must be placed into the light path of a photometer in a defined format. Cuvettes, i.e. sample containers featuring optical windows, are the standard choice for this application.

Hi everyone! We’re back with another great article for you. This time we’ll be covering general lab safety when using a UV Cell, aka a UV cuvette. Now a lot of people can be careless. So proper lab safety can save your health and in some cases, your life. We’re just going to go over a
Within molecular and biochemical applications, as well as in medical diagnostics, determination of the concentrations of substances in solution is a crucial analysis step. Frequently, photometric methods are employed for this purpose, as these can be conducted easily and quickly, and because they often represent the most cost-effective option. In general, (spectro)-photometric methods are based
Important:Make sure that any sample/solution you might have left in your cuvette will not react violently with whatever solution/liquid you will use for cleaning! Do not use strong bases such as potassium or sodium hydroxide. They can damage the cuvettes. A. Low Molecular Weight Water Soluble Samples1) Rinse with purified water.2) Then, rinse with acetone
Cuvettes come in many different materials and sizes. The most common material is UV Quartz which has superior transmission in the UV and VIS range. But for researchers who hate to clean cuvettes, there are some amazing disposable cuvettes available. Now when most people think of disposable cuvettes they think low quality junky cuvettes. This may have been true in
When working in spectroscopy it is important to know the transmission range you are working in. This range will determine what material you need for the cuvette and for people on a budget this will make a big difference. For starters, VIS is short for visible meaning the visible range of the light spectrum. A
The world of cuvettes can be an expansive and confusing world. With so many spectrophotometers on the market and so many different cuvette manufacturers, how do you know which one to choose? Well the good news is that we’re about to make your job much easier. We’ve compiled a list of the Top 10 Things
Spectrometer calibration accuracy is of critical importance for many optical characterization techniques such as Raman spectroscopy and interferometry.1–3 Typically, a calibration lamp is used for spectrometer calibration. Calibration lamps provide distinct, well-defined lines at a known wavelength, and these are assigned to the pixel indices of the detector. However, for small spectral ranges, where only a small number of calibration
