the arrows pointing to the scan area. For OD measurements, the spacers should be
placed with the OD label facing up.
Membrane weight
The membrane weight is used to press fluorescent membranes flat against the fluor
stage. The use of a membrane weight improves image quality, since the membrane
weight removes air bubbles and reduces vibration of the membrane during scanning.
