Types of Cuvettes and Cells
Cuvettes and cells are used to hold samples for spectroscopic and fluorescence measurements and are made from quartz glass, optical glass, plastic, and other materials. In this article, we are going to introduce the following types of cuvettes and cells:
- Spectrophotometer Cuvettes and Cells
- Fluorometers Cuvettes and Cells
- Flow Through Cuvettes and Cells
Spectrophotometer Cuvettes and Cells
iCuvets.Com’s UV-vis range quartz cuvettes and spectrophotometer cells are used for testings that are being conducted in the UV-visible wavelength, that is, from 190-2500 nanometers.
Our UV-vis range quartz cells and spectrophotometer cells are manufactured from UV grade quartz glass. This material provides 83% (HTR & CRF-H) or 80% (CRF & NRC) transmission from 190 to 2500 mm and is the best choice for tests within that range. The transmission of our IR quartz cuvettes is 80% over the usable range of 220 to 3500 nm.
The most widely used types of cuvette cells in the analytical chemistry field are rectangular cells. Our cuvettes are designed and fabricated with precise tolerances to make sure all these rectangular cells will be able to fit the cell holders of virtually any brand of spectroscopic instruments.
Open Top Spectrometer Cuvettes
Open Top Standard 3.5ml Spectroscopy / Absorption Cuvettes
These cuvettes have a volume of 3.5ml, 2 optical windows, and 12.5x12.5x45 mm outer dimension. Custom engraving/labeling available.
- Outside dimensions 12.5 x 12.5 x 45 mm
- Lightpath: 10 mm, ±0.01mm
- PTFE cover included
- Cushioned package and storage box included
- Cell bodies are of fused-wall construction (except NRC)
- Cells are usable in the spectral range 190 - 2500 nm
Accessories for Standard Open top Cuvettes
These silicone lids provide a better sealing than PTFE lids and an alternative for self healing injection. Cuvette racks for easy handling of standard cells.
Open Top Lid Micro/Macro Spectrophotometer Cuvettes and Cells
While 10mm pathlength cuvettes are the most commonly used, we also supply cell path lengths from 0.2 mm to 100 mm, as shown below. All our standard cuvette window thickness is 1.25 mm. These are the most basic, fundamental cuvette types, virtually fitting all types of spectrophotometers.
Micro/Macro cuvette cells refer to the internal volume that holds the sample. These cells have an internal width of 10mm, a length equal to the optical path length (0.2/0.5/1/2/5/10/20/30/40/50100mm) and a height of 45 mm.
The cuvette cells come with Teflon Lids and two polished windows for spectroscopic and absorption measurements. The other sides are frosted to help eliminate stray light.
- Open top, with non-sealing PTFE lid
- Silicone lid available on request for 10mm cells only, providing a liquid-tight seal
- Two polished windows
- Walls polished internally, fine ground externally.
- Designed for all standard cuvette cell holders

Compatible Accessories for Short Path Length Cuvettes:
IR Material Cuvettes
We are here to customize:
Customized Shorter Height Cuvettes
10mm Path Length Spectrometer Cuvette but Height is Shorter than Normal 45mm. Height can be Customized to any Size Required.
Customized Shorter Path Length Cuvettes - Non-standard
Here is some examples of the cuvettes path lengths shorter than standard 10mm, customization to other sizes are also available:
Customized Two Ends Open Spectrometer Cuvettes
Or you might want the cuvette to be bottomless. Let us know and we’ll customize as needed.
10mm Path Length with Wider Polished Windows.
We are able to customize the internal width to fit different applications. The following 10mm cells of absorption spectrophotometers are usually used in colorimetric measurements.
