High-throughput spectrophotometry and routine laboratory testing require cost-effective, reliable sample vessels that eliminate the need for time-consuming cleaning and the risk of cross-contamination. Professional plastic cuvettes, manufactured from high-transparency polystyrene (PS) or PMMA, provide excellent optical clarity for measurements in the visible and UV ranges. As a core category within our optical instruments and microscopes and photometers ecosystems, these disposable cells are essential for modern analytical efficiency.
Why Choose Professional Plastic Cuvettes?
Our curated collection of disposable optical cells is designed for precision and workflow convenience:
- Advanced UV Transparency: We stock BRAND UV Micro Cuvettes, specifically designed for DNA, RNA, and protein quantification with high transmission down to 230 nm.
- Versatile Disposable Options: Utilize Kartell Standard Cuvettes (4.5 ml) and LLG Macro Cuvettes (4 ml) made from polystyrene for clear, streak-free viewing in the visible spectrum.
- Precision Volume Management: Select LLG Half-Micro Cuvettes (1.6 ml) for applications with limited sample volumes, ensuring accurate 10 mm path length measurements.
- Specialized Handling Accessories: Explore Kartell Cuvette Holders for up to 12 cells and PE-LD lids to protect samples from evaporation or contamination during queuing.
LabFriend supplies plastic cuvettes and consumables from global specialists in laboratory plasticware and liquid handling:
- BRAND: The primary specialist for high-end plastic optics, offering industry-leading UV-transparent micro cuvettes for life science research.

Unsure if your assay requires the specialized UV transmission of a BRAND Micro cell or the cost-effective volume of a Kartell standard cuvette? Our team provides local technical support to help you find the correct disposable solution with fast shipping and competitive pricing.
Frequently Asked Questions
1. Can plastic cuvettes be used for UV measurements?
Standard polystyrene cuvettes are only suitable for the visible range, but specialized models like the BRAND UV Micro cuvettes are designed for UV applications (DNA/RNA) with transmission down to 230 nm.
2. What is the benefit of "Half-Micro" cuvettes?
Half-micro cuvettes, such as those from LLG, allow you to perform measurements with significantly less sample volume (approx. 1.6 ml) while maintaining the standard 10 mm path length.
3. Are these cuvettes sold individually or in packs?
Most disposable plastic cuvettes, like those from Kartell and BRAND, are sold in packs of 100 or more to support high-throughput laboratory environments and ensure you always have a fresh cell ready.
4. Do these cuvettes fit standard spectrophotometer holders?
Yes, standard plastic cuvettes have external dimensions of 12.5 x 12.5 mm, making them compatible with almost all commercial spectrophotometers and photometers.
