QATCH requires only 5 microliters of the biopharmaceutical formulation
The measurement is over in 5 minutes with zero cleaning and priming needs
Over 5 decades of shear-rates is tapped by QATCH's viscosity sensor. This information is then used to calculate injection forces and determine manufacturability.
Here are some tips on how to apply a drop of the sample to the sensor:
1. Stabilize your pipetting hand with a leverage (you can put your non-pipetting hand to the instrument and use it as a leverage for the pipetting hand)
2. Pick a pipette tip that is hydrophobic, so that the drop will not roll-up
3. Approach the sensor with the pipette tip and pipette the drop out (1ul-4ul)
4. Touch the drop to the top left gold circle on the sensor
5. Move the tip away immediately
