Hi there Michelle

This coul dbe due to "micro-bubbles" when placing the coverplate on the
section - solved by oneof two methods
1. Apply buffer to the coverplate and place slide on top - similar to
making a blood film, grip fimrly and insert into holder, fill with
buffer and watch drip rate.
2. Immerse the coverplate in buffer and place slide on coverplate and
then as for 1.

Also do you reuse your coverplates? or use new each time?
