Features

Crafted from JGS1 UV Fused Quartz Glass for the 190 nm - 2.5 µm Wavelength Range
Versions with Two or Four Polished Windows for Spectroscopy Applications
100 µL, 700 µL, 1400 µL, and 3500 µL Capacities Available
Standard 12.5 mm Square Profile with 10 mm Transmitted Path Length
Available with PTFE Top Caps or Airtight Stoppers

Our Cuvettes are high-quality cells designed to hold liquid samples. The JGS1 UV fused quartz glass construction allows these cuvettes to be used with UV light at wavelengths as low as 190 nm, as well as with visible and infrared light up to 2.5 µm. Thorlabs offers cuvettes with either two polished sides, for use in absorption spectroscopy experiments, or four polished sides, for use in fluorescence spectroscopy. The polished sides can be cleaned using standard optics cleaning procedures. Versions are also available with one of two PTFE tops: a cap to block dust and other particles or a stopper to prevent evaporation and provide an airtight seal.

The standard 12.5 mm square outside dimension and 10 mm transmitted path length through the sample make these cuvettes compatible with most spectrophotometers as well as our cage-compatible Cuvette Holder and Fiber Optic Filter and Cuvette Mounts. We offer macro, micro, and super micro sizes (see the tables below for more information), sold in packs of two. The 100 µL cuvettes with four polished sides as well as all 3500 µL cuvettes are also available in a version with enhanced chemical resistance. All cuvettes are engraved on the outer surface with the Item # and a letter "Q" designating quartz construction and the typical input side.

The super micro and micro cuvettes with two polished sides are assembled with glue. Our other cuvettes are assembled by heating the quartz to a high temperature and applying pressure to adhere the pieces together. Of these, micro cuvettes that are polished on four sides and all standard macro cuvettes have a quartz powder applied to the edges before heating, while the enhanced-chemical-resistance super micro and macro cuvettes are constructed by finely polishing the quartz before heating.

Solvent Compatibility
All standard cuvettes should not be used with benzene, toluene, aqua regia, ethanol, corrosive solutions, or other similar substances, as they may degrade the bonds between the pieces and cause the cuvette to leak. The cuvettes with enhanced chemical resistance are compatible with corrosive solutions such as aqua regia. Contact Tech Support for instructions on cleaning the cuvettes found on this page.

I ordered CV10Q1400FS and found that both cuvettes included showed massive auto fluorescence which ruined any sample signal. When testing the same sample in different cuvettes the expected signal was produced.

Hello, thank you for contacting Thorlabs. We're sorry to hear about the issues you are experiencing with these. We have reached out to you directly to troubleshoot this further.

It seems like the transmission is low for a quartz cuvette. Is the transmission in the graph internal transmission or transmission including Fresnel reflection losses? Thanks very much.

Response from Jeremy at Thorlabs: The transmission graph includes the Fresnel reflection losses from 4 surfaces.

Hi, This line of product is very attractive, unfortunately the cap that you are using are not good enough for the application I'm looking for. By using volatile solvent like methanol the square lid are not good enough to stop the evaporation of it. Also, if one is using oxygen sensitive product a better lid would prevent the oxygen to penetrate the cell for at least a short amount of time. The lid I'd have liked to see (at least in option) for those cuvette is of this kind: http://www.hellma-analytics.com/kuevetten/135/en/pg_id,40$g_id,28$item_id,114/absorption-cells.html#114 Best Emmanuel

Response from Tim at Thorlabs to Emmanuel: Thank you for your feedback! This would certainly be a valuable addition and we're looking to make this available as an off the shelf solution.

These UV Fused Quartz Cuvettes have two polished sides for use in absorption spectroscopy experiments and two frosted sides for handling. For the super micro (100 µL) and micro (700 or 1400 µL) cuvettes, the unused areas of the polished, optical surfaces are blackened to reduce scattered light. The polished sides can be cleaned using standard optics cleaning procedures. Since these cuvettes only have two polished windows, they are not appropriate for use in fluorescence spectroscopy where it is necessary to have four polished windows to allow measurement of the fluorescence at right angles to the beam path. Thorlabs also offers cuvettes with four polished sides below.

These cuvettes have standard 12.5 mm square outer dimensions, a 10 mm transmitted path length through the sample, and are available with 100 µL, 700 µL, 1400 µL, or 3500 µL capacities. The 3500 µL cuvettes are available in a standard version (Item # C10Q35) as well as a version with enhanced chemical resistance (Item # C10Q35E). Each cuvette is engraved with the Item # as well as a letter "Q" that designates its quartz construction and the typical input side, and each comes with a PTFE cap to prevent contamination by dust or other particles.

The 100 µL, 700 µL, and 1400 µL cuvettes (Item # CV10Q1, CV10Q7, and CV10Q14, respectively) are assembled with glue, which can be destroyed by benzene or other solutions with strong corrosive characteristics. Both 3500 µL cuvettes are assembled by first heating the quartz to a high temperature and then applying pressure to adhere the pieces together, eliminating the need for glue. The standard 3500 µL cuvette (Item # CV10Q35) has quartz powder applied to the edges before heating, whereas the 3500 µL cuvette with enhanced chemical resistance is made by finely polishing the quartz pieces before attaching, consequently providing smoother seams. This method allows the cuvette with enhanced chemical resistance to hold solutions with corrosive properties, similar to those of nitrohydrochloric acid (aqua regia), without being damaged.

Please note that the standard cuvettes should not be used with benzene, toluene, aqua regia, ethanol, corrosive solutions, or other similar substances, as they may degrade the bonds between the pieces and cause the cuvette to leak.

Each cuvette is engraved with the Item # as well as a letter "Q" that designates its quartz construction and the typical input side, and each comes with a PTFE stopper to create an airtight seal and to prevent evaporation and atmospheric contamination of the contents. The stopper should be inserted gently into the top of the cuvette; excessive force will cause difficulty with removing the stopper.

The standard 100 µL, 700 µL, and 1400 µL cuvettes (Item # CV10Q1A, CV10Q7A, and CV10Q14A, respectively) are assembled with glue, which can be destroyed by benzene or other solutions with strong corrosive characteristics.

These UV Fused Quartz Cuvettes have four polished sides for use in fluorescence spectroscopy experiments. The four polished windows allow measurement of the fluorescence at right angles to the beam path and can be cleaned using standard optics cleaning procedures. While these cuvettes are designed for use in fluorescence, the through beam windows can be used independently for other spectroscopic applications. Thorlabs also offers cuvettes with two polished sides and two frosted sides designed specifically for these other applications (sold above).

These cuvettes have a standard 12.5 mm square outer dimension, a 10 mm transmitted path length through the sample, and are available with 100 µL, 700 µL, 1400 µL, or 3500 µL capacities. Each cuvette is engraved with the Item # as well as a letter "Q" that designates its quartz construction and the optical window axis, and each comes with a PTFE cap to prevent contamination by dust or other particles.

The cuvettes are assembled by first heating the quartz to a high temperature and then applying pressure to adhere the pieces together, eliminating the need for glue. For the standard 700 µL, 1400 µL, and 3500 µL cuvettes (Item # CV10Q7F CV10Q14F, and CV10Q35F, respectively), quartz powder is applied to the edges of the pieces prior to heating. For the cuvettes with enhanced chemical resistance, available in 100 µL or 3500 µL capacities, the quartz pieces are finely polished before attaching, consequently providing smoother seams. This method allows the enhanced-chemical-resistance cuvettes to hold solutions with corrosive properties, similar to those of nitrohydrochloric acid (aqua regia), without being damaged.

Note that all standard cuvettes should not be used with benzene, toluene, aqua regia, ethanol, corrosive solutions, or other similar substances, as they may degrade the bonds between the pieces and cause the cuvette to leak.
