Cuvettes for PerkinElmer LAMBDA Spectrophotometers

1. Standard Compatibility — What Fits a PerkinElmer LAMBDA Cuvette Holder

A PerkinElmer LAMBDA spectrophotometer's cuvette well accepts the standard rectangular cell format: 12.5 × 12.5 × 45 mm body, 10 mm path length, standard Z-dimension, transmitting-window centre at 8.5 mm. This is the same cell geometry used by virtually all benchtop UV-Vis instruments, so any standard 10 mm cuvette from Scuvette fits the well physically. See all instrument brands →

For normal absorbance you need a two-clear-side cell; for fluorescence on a PerkinElmer fluorometer or similar you need a four-clear-side cell (see section 4). If you use a micro-cell or a specialty holder, confirm the beam height against your instrument manual — that is the only dimension that occasionally varies between holders.

3. Path Length Choice on a PerkinElmer LAMBDA

Use 10 mm for routine absorbance. If your sample would read over-range (A > ~3) at 10 mm, drop to a 1–5 mm short-path cell rather than diluting; for very dilute samples use a longer path. The same Beer–Lambert relationship (A = ε·c·l) applies on every PerkinElmer LAMBDA instrument. Path length guide →

4. Fluorescence Note (Four-Clear-Side Cells)

A PerkinElmer LAMBDA fluorescence system collects emitted light at 90° to the excitation beam, so the cell must have four optically clear sides. Standard two-window absorbance cells block the emission path. Use a proper fluorescence cuvette with a low-fluorescence quartz grade.

5. Recommended Scuvette Cells

• 10 mm open-top quartz cuvette — the everyday PerkinElmer LAMBDA cell.
• Screw-cap quartz cuvette — sealed work, micro sizes available.
• Four-clear-side fluorescence cell — for PerkinElmer fluorometer and similar.
• Micro & sub-micro quartz — small-volume, 10 mm path retained.
• Short-path cuvettes — 1–5 mm for concentrated samples.
