Versatile Material Choices for PrecisionThese disposable cuvettes are manufactured using either polystyrene (PS) or methacrylate (PMMA), ensuring high optical quality suitable for both ultraviolet and visible spectroscopy. The selection of material enables reliable light transmission: PMMA covers a wider range and is preferred for UV applications, while PS is ideal for visible light analyses.
User-Friendly and Hygienic PackagingOur spectrophotometer cells are available individually wrapped or in bulk-packed options, catering to different laboratory needs. Individual wrapping minimizes contamination risks and bulk packing supports high-throughput environments, ensuring convenience and operational efficiency for routine sample handling.
Compatibility and Measurement AccuracyThese cuvettes fit most standard spectrophotometers, providing flexibility across various brands and models. Designed with a rectangular shape and a base thickness of approximately 1.2 mm, they ensure consistent placement and precise measurement for high-confidence analytical results.
FAQs of Disposable Cuvettes & Spectrophotometer Cells:
Q: How do I use disposable spectrophotometer cuvettes for sample analysis?
A: To use the cuvettes, manually place the cell into your spectrophotometer, fill with your sample (around 3.5 ml), and ensure the clear sides are aligned with the light beam. After use, dispose of the cuvette according to lab protocols, eliminating the need for washing or re-use.
Q: What is the benefit of choosing optical grade plastic over glass for cuvettes?
A: Optical grade plastic (PS or PMMA) offers high clarity, cost-effectiveness, and eliminates the risk of breakage associated with glass. Additionally, these materials cover broad light transmission ranges suitable for both UV and visible analyses, providing precise results.
Q: When should I select PMMA cuvettes instead of PS cuvettes?
A: Choose PMMA cuvettes for assays requiring UV transparency from 280 nm upwards. PS cuvettes are preferable for visible light measurements, as their transmission range starts at 340 nm. Selecting the appropriate material optimizes spectral accuracy.
Q: Where can these disposable cuvettes be used?
A: These cuvettes are ideal for laboratories, academic research, diagnostic testing centers, biotech firms, and chemical analysis facilities. They are widely supplied and exported across India by manufacturers, suppliers, and traders.
Q: What process ensures the accuracy of path length in these cuvettes?
A: Manufacturing is tightly controlled, resulting in a standard path length of 10 mm with an accuracy of 0.1 mm. This consistent dimensional precision supports reliable and reproducible spectrophotometric readings across experiments.
Q: Are the cuvettes bulk packed or individually wrapped?
A: Depending on your requirements, cuvettes are available either individually wrapped for sterile, one-time use or in bulk-packed formats for extensive laboratory workloads, providing flexibility in inventory management and sample preparation.
