The BioDrop Duo+ combines Biochrom's patented fixed pathlength microvolume port for reliability and consistency of results down to 1µL of sample with the additional benefit of a standard 10 x 10mm cuvette port. At a range of 190 - 1100nm, pre-programmed life science methods and general spectrophotometry capabilities, this two in one instrument will fulfil the needs of the most demanding laboratories.

The microvolume sample port is easy to use: simply pipette as little as 1µL and measure. Cleaning the port is easy too: just wipe with a lint free tissue to reduce sample carry over to undetectable amounts. Should a sample be unintentionally left on the port to dry out, mild detergents and distilled water should be used for a more thorough cleaning. The cuvette port of the BioDrop Duo+ adds the versatility for the instrument to be used just like any standard spectrophotometer. For applications where a higher sample volume is required, eg. OD600 and enzyme kinetics, the Duo+ is a truly flexible instrument.

The BioDrop Duo+ microvolume sample port uses no moving parts. This means that the instrument provides excellent reproducibility without the need for regular pathlength calibration. Measurements are also highly accurate because the pathlength of the port is highly specified to 5µm.

Pre-programmed methods on the BioDrop Duo+ instruments include DNA, RNA and oligo concentration, protein assays, OD600, and an extensive menu of commonly available fluorescent dyes for nucleic acids and proteins. Should there be a method specific to your lab, this can be written in using the versatile Equation Editor. Results can be saved to the on-board memory of the BioDrop Duo+, saved to USB as a .csv file, printed to the optional integrated serial printer, or analysed in the powerful BioDrop Resolution PC Software. BioDrop Resolution CFR is also an option for those labs that are 21 CFR Part 11 compliant.
