Cuvettes for Your Spectrophotometer Brand

Nearly every benchtop UV-Vis and UV-Vis-NIR spectrophotometer uses the same standard rectangular cuvette well — 12.5 × 12.5 × 45 mm body, 10 mm path length, standard Z-dimension, transmitting-window centre at 8.5 mm. Pick your instrument maker below for the exact cell recommendations.

1. One Standard Well, Every Major Brand

A cuvette is consumable lab glassware defined by standard dimensions, not by instrument brand. Agilent Cary, Shimadzu, PerkinElmer LAMBDA and Thermo Fisher Evolution spectrophotometers all accept the same standard 10 mm quartz cell physically. The only dimension that occasionally varies between holders is the beam height — confirm it only for micro or specialty cells against your instrument manual.

2. Choose Your Instrument Brand

3. Which Cell Format Do You Need?

Application	Recommended cell	Why
Routine absorbance	10 mm open-top quartz	Standard well, deep-UV to visible
UV-Vis-NIR / wide band	JGS1 quartz	Broad band for UV-Vis and NIR
Volatile / hygroscopic samples	Screw-cap quartz	Seals the well against evaporation
Fluorescence	Four-clear-side cell	90° emission collection needs 4 windows
Limited sample volume	Micro / sub-micro quartz	Keeps 10 mm path at small fill

4. Not Listed, or Need a Custom Cell?

If your instrument is not listed above, or you need a special path length, dimension or screw-thread (M6/M7/M10/M12/M16) cell, send us your model and drawing. We make custom cells to your specification with no minimum order quantity. Contact Scuvette →

Instrument-Compatible Cuvettes — Frequently Asked Questions

Do standard cuvettes fit all spectrophotometer brands?

Yes. The standard rectangular well (12.5 × 12.5 × 45 mm body, 10 mm path, standard Z-dimension, window centre at 8.5 mm) is used by virtually all benchtop UV-Vis instruments, including Agilent Cary, Shimadzu, PerkinElmer LAMBDA and Thermo Fisher Evolution. Any standard Scuvette 10 mm cell fits physically.

Do I need a brand-specific cuvette?

No. Cuvettes are defined by standard dimensions, not by instrument brand. A standard cell from any qualified maker fits the well. Scuvette supplies the standard geometry in quartz, glass and specialty formats.

Which cuvette do I use for fluorescence?

Use a four-clear-side (four-window) fluorescence cell so emitted light can be collected at 90°. A normal two-window absorbance cell blocks the emission path. Fluorescence cuvettes →

My sample is too concentrated for 10 mm — what then?

Switch to a 1–5 mm short-path cell instead of diluting, which keeps preparation simple and accuracy high. Short-path cuvettes →

Can Scuvette make a custom cell for my instrument?

Yes — special path lengths, dimensions and screw-thread (M6/M7/M10/M12/M16) cells made to your drawing, with no minimum order quantity. Request a quote →
