Cuvettes et cellules de fluorescence
Les cuvettes et les cellules sont utilisées pour contenir des échantillons pour les mesures spectroscopiques et de fluorescence et sont fabriquées à partir de verre de quartz, de verre optique, de plastique et d’autres matériaux. Dans cet article, nous allons présenter les types de cuvettes et de cellules suivants:
- Cuvettes et cellules de fluoromètres
- Écoulement à travers les cuvettes et les cellules
Fluorometer Cuvettes and Cells
Open Top Fluorescence Cuvettes
Open Top Standard 3.5ml Fluorometer / Fluorescence Cuvettes
These cuvettes have a volume of 3.5ml, 4 optical polished windows, and 12.5 x 12.5 x 45 mm outer dimension. Custom engraving/labeling service available.
Accessories for Standard Open top Cuvettes
These silicone lids provide better sealing than PTFE lids and an alternative for self-healing injection. Cuvette racks for easy handling of standard cells.
Open Top Micro/Macro Fluorometer Cuvettes and Cells
While 10mm pathlength cuvettes are the most commonly used, we also supply cell path lengths from 1 mm to 50 mm, as shown below. These are the most basic, fundamental cuvette styles. These cuvettes are also Dual Path Length Cuvettes.
Dual Path Length Cuvettes and Cells
By changing the orientation of the dual path length cuvettes in the cuvette holder, researchers can make both fluorescence and absorption measurements in a single cuvette with different path lengths.
All cuvettes below have a 10mm path length in one direction and a smaller(bigger) path length at 90°. All four walls are clear windows.
Longer or smaller light path lengths cuvettes are available by customization.
Compatible Accessories:
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 are some examples of the cuvettes path lengths shorter than standard 10mm, with 4 clear windows for fluorescence applications, customization to other sizes is also available:
Tandem/ Divided Cuvette
Customized Two Ends Open Cuvettes
Or you might want the cuvette to be bottomless. Some standard size cuvettes can also be tailored to bottomless.
Stopper Fluorometer Cuvettes
Stopper 10mm Pathlength Fluorescence Cuvettes
Instead of open-top lids, this type of fluorometer cuvettes is equipped with PTFE stoppers which are useful for fluorescence experiments that require airtight sealing.
Micro/Macro Stopper Fluorometer Cuvettes Cells
Compatible Accessories:
Short-Path Length Fluorescence Cuvette with Stopper
Triangular Fluorescence Cells
Fluorescence cuvettes for use in front-face illumination experiments. These triangle cuvettes are useful for measurements with dense samples with high optical densities.
- Fits 12.5mm square cell holder
- Three windows polished
Screw Cap Fluorometer Cuvettes
Screw Cap Standard Fluorometer Cuvettes, Rectangular
Fluorometer cuvette cells with PTFE screw caps and PTFE/silicone liner for use in anaerobic or long-term storage applications. Each cuvette comes with a closed screw cap and liner. Alternatively, a 2mm center hole open screw cap with a SEPTA for self-healing injection applications.
Micro Bouchon à vis Cuvettes et cellules de fluorimètre
Compatible Accessories:
Short Height Screw Cap Fluorometer Cuvettes
Short Height and 12*12mm Fluorescence Cuvettes
This type of screw cuvette has 12*12*48mm out dimension.
Graded Seal Fluorescence Cuvettes
Cuvettes with quartz to borosilicate graded seal tubes. This structure allows for these long mouth cuvettes to be welded to other borosilicate structures. The stock tube size is OD 8mm and ID 6mm.
Long mouth cuvette with quartz material tube is also available with a lower cost.
Semi-micro Spectrophotometer Cuvettes
Open tops with Teflon lids, the sample volume is reduced by making the internal width to 1/2/3/4/5mm wide, making the cuvette volume from 3.5ml to 0.35/0.7/1/1.4/1.7mL. The external dimension is still 12.5*12.5*45mm. These cuvettes have a path length of 10mm.
Sub-Micro Fluorescence Cuvettes
Sub-Micro Self-masking Open Top Lid Fluorometer Cuvettes
Fluorometer cells with ultra-micro capacities less than 350uL.The Z dimension is important for sub micro volume cuvettes, where there is a limited sample aperture.

All Black Self Masking Sub-micro Cuvettes
The following self-Masking cuvettes are designed with black walls that absorb direct and scattered light.

Flow Through Cuvettes and Cells, Quartz
Flow through cuvettes and cells are used with continuous flow measurements in the field of chromatography or system production, another application is sipper systems when individual sample measurements are aspirated into the flow cells.
A wide selection of designs of flow cell volumes, flow patterns, optical path lengths and tubing requirements are available with us to fit each application. It’s our effort to offer this wide range of cells and simplify the process of selection as much as possible.
The quartz cuvettes are accurate throughout the 190 nm to 2500 nm spectral range. If you have questions or need a custom design of flow cells, please email us and we will answer your requests promptly.
Both Ends Open Flow Cells
These types of cuvettes are bottomless and come without quartz or steel connectors.
Flow Through Cuvettes with Quartz Connectors
Flow Through Cuvettes with Steel Connectors
Mounted Type
Demountable Cuvettes
Demountable cuvettes are usually used in measurements of circular dichroism.
Compatible Accessories:
Flow Cells with Side Quartz Connectors
Flow Cells with Screw PTFE Connectors
Sub-micro Self Masking Flow Cells
The following self-Masking cuvettes are designed with black walls that absorb direct and scattered light.
Quartz Connectors Flow Through Cuvettes
M6 Connectors Flow Through Cuvettes
By using M6 threaded connectors, flow cells can be easily and securely connected to pump and manifold plumbing systems. The M6 type is standard metric threaded which makes a tight seal when threaded into the top of the flow through cells.
