Cuvettes category banner

At CM Scientific we are trusted with supplying cuvettes and cells to universities, research establishments and leading commercial organisations worldwide. We offer a full range of high quality optical cuvettes and cells for use in a wide range of applications and instruments including the Spectrometer, Spectrophotometer and the Fluorometer.

At CM Scientific we supply both standard glass cuvettes and UV cuvettes for spectrophotometers and fluorometers. As standard our Spectrophotometer cuvettes and cells have two windows polished and fluorometer cuvettes have all four walls polished. All of our cuvettes also come with a range of lids and stoppers including PTFE lids and Teflon stoppers.

Sourcing from CM Scientific you can be assured that the cuvette or cell that you procure will be of the highest manufacturing standards. All of the cuvettes and cells that we supply are produced only from the highest quality quartz and optical glass. Whether it is an optical glass cuvette or a UV cuvette, all of our products undergo a meticulous quality control system to ensure that they meet the highest industry standards and are compatible with most spectrophotometers and fluorometers on the market.

If the product you require is not listed please contact our sales team who will be pleased to help with your enquiry.

Application Notes

How To Use a Cuvette?

The basics of using a cuvette are, a liquid sample is placed in the cuvette carefully to ensure that it is not over filled and the outside of the cuvette is kept clean. Then the cuvette is inserted into the instrument such as a Spectrometer or Fluorometer. The beams inside of the instrument can pass through the quartz/glass walls of the cuvette due to their optical purity and 'read' the sample. The sample's data is then analysed against known standards of materials.

What is a Cuvette?

A cuvette (sample cell, absorption cell) is, in its basic level, fundamentally a test tube designed for use with optical analysis. Standard cuvettes are generally square or rectangular in cross section to avoid refraction artefacts. Depending on what part of the spectrum is under consideration, they may be made of quartz or optical glass although plastic cuvettes do exist for less demanding measurements.

  • A container with specific dimensions (particularly thickness) and optical properties, used to examine coloured or colourless solutions that are free of turbidity, as well as the light scattering of turbid suspensions, such as bacterial suspensions. Its efficacy depends on its chemical composition; e.g., one made of quartz is used for examination of materials in the ultraviolet region of the spectrum and one made of Pyrex is used for examination of materials in the visible range.

  • A small often transparent laboratory vessel (as a tube) (Source: Merriam-Webster Online Dictionary)
  • Laboratory vessel: a transparent tubular laboratory vessel or dish for holding a liquid (Source: Encarta? World English Dictionary)

Types of Cuvette Available

At CM Scientific we supply both standard glass cuvettes and UV cuvettes for spectrophotometers and fluorometers. As standard our Spectrophotometer cuvettes and cells have two windows polished and fluorometer cuvettes have all four walls polished. All of our cuvettes also come with a range of lids and stoppers including PTFE lids and Teflon stoppers.

All of these cuvettes are available made with two different materials.

Optical Glass Cuvettes

These cuvettes are made from Optical Glass which is suitable for transmission wavelengths from 320nm to 2,600nm and are available in a range of path lengths.

UV Quartz Cuvettes

UV quartz cuvettes for UV light are suitable for transmission wavelengths from 195nm to 2,500nm and are also available in a range of path lengths.

At CM Scientific we offer the full range of standard cuvettes through our online store but on top of that we also sell an additional range of more specialised cuvettes and cells including those listed below:

  • Micro fluorometer cell
  • Micro cell with frosted walls
  • Micro cell with black walls
  • Self masking continuous flow through cell
  • Cylindrical cell
  • Absorption rectangular
  • Rectangular with screw cap
  • Long Outlet Cylindrical
  • Cells for reflection measurements
  • Graded seal
