1.5 mL Micro Cuvettes with 2 Clear Optical Sides, 500/Case
The Globe Scientific Micro Cuvette, 1.5 mL with 2 Clear Sides is engineered for accurate low-volume optical readings in routine spectrophotometry, nucleic acid and protein quantification, and bacterial growth (OD600) monitoring. Two polished clear faces define a fixed light path, while frosted sides reduce handling artifacts. Compact geometry conserves precious sample during dilution series and kinetic assays.

Frequently Asked Questions
What is the optical path length of these micro cuvettes?
The two clear sides establish a standard 10 mm light path suitable for most visible-range spectrophotometers, with a minimum working volume well below the 1.5 mL capacity.
Are these cuvettes suitable for UV measurements?
Standard polystyrene optical plastic transmits well in the visible range but absorbs in the UV. For A260/A280 readings, verify your instrument's wavelength and consider UV-transparent alternatives if low-UV accuracy is critical.
What is the difference between SKU 112157 and 112137?
Both are 1.5 mL micro cuvettes with two clear optical sides. SKU 112137 is specified as PS (polystyrene); both ship 500 per case at the prices listed above.
Are these cuvettes reusable or single-use?
They are intended as economical single-use, disposable cuvettes to prevent cross-contamination and carryover, though brief reuse with compatible aqueous samples is possible if rinsed promptly.
