Spécifications techniques

The Halo DNAmaster complements the existing range of Halo spectrophotometers and plate readers. It is designed for the measurement and analysis of precious samples by requiringonlymicrovolumequantities. Naturally,DNAmaster features the same ruggedness, reliability, precision and reproducibility synonymous with the Halo family. The Halo DNAmaster is equipped with a comprehensive selection of on-board functions for versatility and suitability to many life science applications involving nucleic acid, proteins and bacterial cultures. 

Spectral Features 

The Halo DNAmaster boasts a wavelength range from 200 to 900nm, an absorbance range between 0 - 4 O.D. and a wavelength accuracy of 1nm. Low noise (~0.005 O.D.) combined with a photometric accuracy of ±0.01 O.D. and 4nm bandwidth ensure excellent sensitivity, accuracy and reproducibility.

Minimal Volume for Precious Samples 

By virtue of the innovative ‘Ultramicro’ cell as little as 0.5μl of sample is required (optional cap is needed). Simply pipette the sample on the appropriate section of the Ultramicro cell, perform the measurement and then wipe off or aspirate the sample for further downstream applications. 

If microvolume measurement is not a must, the Halo DNAmaster is also available configured with 50ul cells. However, both configurations can be used as a conventional spectrophotometer with standard 10mm optical path length cuvettes. 

Ultramicro Cell

The Ultramicro cell utilises fibre-optic technology and is designed for measurement of extremely small volumes of DNA/RNA samples with high accuracy and reproducibility. In applications involving very high or very low DNA concentrations, a single light path is often insufficient, however the interchangeable cap of the Ultramicro cell imparts light paths of 1 mm and 0.2 mm respectively and effectively creates virtual dilutions to overcome such situations. Other pathlengths are available for different volume and concentration limit. The cap can also prevent the sample from drying up and ensure that measurements remain reproducible since sample characteristics can be affected by solvent evaporation.
