The Hellma TrayCell is a Fibre-Optical Ultra-Micro Measuring Cell and designed for measurements e.g. of DNA/RNA or protein samples and enables
highly accurate analysis of extremely small samples with remarkable reproducibility. The dimensions of the TrayCell are equivalent to a standard cuvette in order to work in most spectrophotometers. Using
the 1 mm or 0.2 mm cap creates a defined optical light path of 1 mm and 0.2 mm respectively. This generates virtual dilution factors of 1:10 or 1:50 in comparison to a measurement with a standard 10 mm cuvette. This feature saves time and avoids dilution errors. If desired, samples can be retrieved after the measurement for further processing.
The required sample volume for the 1 mm cap is 3 ìl to 5 ìl and for the 0.2 mm cap 0.7 ìl to 5 ìl.
The measurement remains reproducible because the sample will not be enriched by evaporation of the solvent.
Features:
• Fibre Optic wavelength range 190 – 1100 nm
• Works with 0.7ìl – 5ìl sample volume
• Concentration range for DNA from 2 to 5.000 ng/ìl without dilution detectable (depending on spectrometer linearity)
• Compatible with most commercially available spectrometers
• High precision and excellent reproducibility
• Dilution is not necessary
• Filling, measuring and cleaning within seconds
