Volume Calculation for Mixing Reagents

There are 2 dead volumes to consider when mixing reagents online that is determined by the VALENT Software:

      • About 300µL is lost during the mixing process itself, which should be accounted for in the sample calculations below.
      • There is a 50µL dead volume for all reagent and mixing vials due to the limitation of probe.

Below is an example of how dead volumes work for mixing reagents.

DAB Reagent = DAB Chr DAB Buffer

The dispense volume per slide is 300µL with an extra 20µL needed, (the extra 20µL volume is to compensate for lost volume 
during slide application) for a total of 320µL. 

DAB Reagent
    Volume for 12 slides=  12 * 320µL= 3840µL
    Dead volume = 50µL
    Total DAB Reagent required for 12 sides = 3890µL

a� DAB Chromogen
     Volume needed for 12 slides = 240µL
     Dead volume = 50µL
     Total volume = 290µL

b� DAB Buffer
     Volume for mixing 12 slides = 3950µL
     Dead volume = 50µL
     Total = 4000µL

After mixing buffer and chromogen, the total volume of DAB Reagent will be 4190µL (240µL + 3950µL). During the mixing 
process, 300µL is lost leaving 3890µL, (4190µL -300µL).
