Life Science Programs
Halo BIOmaster contains onboard functions for the quantification of nucleic acid, including dsDNA, ssDNA, RNA and Oligonucleotides. The purity of the nucleic acid can also be determined with the ratio A260/A280 calculation. Protein concentrations can be measured from a range of colourimetric assays such as Bradford, Lowry, Biuret and BCA. Standard calibration data and curves can also be displayed. Furthermore, proteins can be quantifi ed at 280nm.
Bacterial cell density at 600nm can also be measured under the OD600 cell culture optical density function. It can define a bacterial culture in exponential growth phase and at the most appropriate time for harvest or induction.
Compact Optics with Full Range Scanning
The single beam optics are compact resulting in signifi cant bench space saving. The long life Xenon lamp optics system in the Biomaster ensures quick and reliable performance.
Color Touch Screen Operation
The intuitive color touch screen provides simple access to an extensive range of function. The touch screen is sensitive to stylus or hands (with and without gloves). Icon driven on board software improves accessibility and the quick action keys are another convenience feature.
Various Measurement Modes
In addition to the Lifescience program, BIOmaster also features conventional spectrophotometer functions such as single/ multiple wavelength analysis, spectrum scanning, kinetics and concentration measurement.
Optional Accessories
A various selection of accessories include: microcell holder, flow cell with sipper, temperature control holder, long path-length cuvette holder and an automatic multiple cell holder is available to enhance different application needs.
Storage and Data Output
External storage with SD card allows data export to PC in compatible text or spreadsheet format. MasterReport software is available to convert the raw data to an organized data table. Method and result storage is almost unlimited by exchanging the SD card when needed. A printer option is available for direct printing of data and / or graphics. Advanced control, analyses and reporting can be performed with the optional UV Detective software installed on a computer.
Validation Function
To ensure optimum instrument performance, self diagnosis functions are executed with the GLP/GMP wizard for performance validation and auditing.
