Choose a disposable optical format—and the matching cap.
Polystyrene cuvettes provide a 10 mm light path for measurements from 340 to 800 nm. Four cuvette configurations and two clearly labeled cap-only options let you match volume and opening shape.
10 mm
Light path
340–800 nm
Specified wavelength range
4 cuvettes
1.5, 2.5 or 4.5 mL

500 per cap pack
Designed for Your Workflow
Visible-range optics
Optically clear polystyrene for the specified 340–800 nm range.
Standard exterior
Cuvettes measure 12.5 × 12.5 × 45 mm.
Opening choices
Round-opening and square-opening options use different matching caps.
Separate ordering units
Cuvettes: 1000 per pack; caps only: 500 per pack.
Select the Right Format
Select a cuvette or a cap-only option deliberately. A 1000-cuvette pack needs two 500-cap packs for one cap per cuvette. Verify instrument holder geometry, wavelength and sample compatibility.

Selection and Use Tip
Select a cuvette or a cap-only option deliberately. A 1000-cuvette pack needs two 500-cap packs for one cap per cuvette. Verify instrument holder geometry, wavelength and sample compatibility.
Frequently Asked Questions
Are caps included with the cuvettes?
No. Caps are ordered separately. S4100-5 and S4100-6 are cap-only packs with 500 caps each, not cuvette packs.
Which cap fits which cuvette?
Round S4100-5 fits S4100-1 and S4100-2. Square S4100-6 fits S4100-3 and S4100-4.
What volumes are available?
S4100-1: 1.5 mL round opening; S4100-2: 2.5 mL round; S4100-3: 1.5 mL square; S4100-4: 4.5 mL square.
Can these replace quartz cuvettes for 260 nm measurements?
No. Their specified range is 340–800 nm. They are not represented as equivalent to quartz cuvettes or suitable for 260 nm nucleic-acid measurements.
Which instruments does MTC Bio list?
Examples include Spectronic 200, 20/20D and Educator, Genesys, Carolina and Accuris SmartDrop models. Verify the exact holder and measurement method; this is not OEM status or universal compatibility.
What are the optical path and external dimensions?
The light path is 10 mm and exterior dimensions are 12.5 × 12.5 × 45 mm, with two optical sides.
How many cuvettes are in one order unit?
Each cuvette option contains ten trays of 100, totaling 1000. Cap-only options contain 500 caps. The workbook sellable UOM is a pack.
Are the cuvettes suitable for every solvent?
No universal chemical compatibility is claimed. Confirm polystyrene compatibility with the sample, solvent, temperature and exposure time before use.
