Z-height focus

Z-height adjustment is extremely important in obtaining the best possible signal from every sample. Even a focus positioning error as small as 0.2 mm can lead to signal decrease of up to 25%. Read more about how the focal height setting impacts measurement results in the HowTo Note: How to optimise the focal height of your microplate reader measurements? and How to reduce data variability in heterogenous cell samples. 

BMG LABTECH's auto Z-height focus scans the whole sample with 0.1 mm resolution and then determines the height at which the strongest signal can be measured. While most readers set Z-height to “low”, “medium”, or “high”, or in 1 mm increments, the PHERAstar^® FSX, VANTAstar^®, and CLARIOstar^® offer precise control in 0.1 mm increments.

Automatic Z-height adjustment is just another feature that allows the PHERAstar FSX, VANTAstar^®, and CLARIOstar to detect the best emitted signal for every assay, every time.
