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 requiring only microvolume quantities. DNAmaster features the same ruggedness, reliability, precision and reproducibility synonymous with the Halo family.
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 requiring only microvolume quantities. 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.
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 0.5 of sample is required. Simply pipette the sample on the appropriate section of the Ultramicro cell, perform the measurement and then wipe off clean or aspirate the sample for further downstream applications.
The Halo DNAmaster can also be used as a conventional spectrophotometer with standard 10mm optical path length cuvettes. The Halo DNAmaster is also available configured with 50 cells. However, both configurations can also be used as a conventional spectrophotometer with standard 10mm optical path length cuvettes.
User Friendly Operation and Information Rich LCD Display
The 90mm x 120 mm, colour LCD screen is touch-sensitive with intuitively designed software for quick selection by sample type. Effortless step by step navigation and a virtual QWERTY keyboard provide fast and efficient input and analysis. Data is displayed numerically and also in a graphical format (where applicable) with the further option of direct printing or storage in a SD card.
Nucleic Acid Analysis
The Halo DNAmaster is configured with onboard functions for the quantification of nucleic acids. Select the nucleic acid of choice such as double stranded DNA, single stranded DNA, RNA or oligonucleotides and absorbance measurements at the prescribed wavelength are directly converted into concentration units. The detection limit of the Halo DNAmaster is 20ng/ (double stranded DNA).
The purity of nucleic acids can also be determined from ratio calculations such as A260 / A280 nm for protein contamination of DNA preparations. The Halo DNAmaster can also measure concentrations DNA, RNA and oligonucloetide-dye complexes.
The Halo DNAmaster measures protein concentrations from a range of colorimetric assays such as Bradford, Lowry, Biuret and BCA. In addition to numerical data the standard calibration curve can be displayed. Furthermore measure protein alone at 280nm or protein-dye complexes that absorb at 246nm.
Cell Culture Optical Density
The Halo DNAmaster also measures bacterial cell density at 600nm. Absorbance readings of approximately 0.4units define a bacterial culture in exponential growth phase and at the most appropriate for harvesting or induction.
