[Histonet] Renal biopsies washing off slides

[Tracey.Lenek <@t> CLS.ab.ca]

We are having a transient issue with renal biopsies washing off coated slides.  They are all processed in B5 from VWR and diluted with formalin from Fisher and a small amount of safranin to color the tissue.  Tissue from yesterday appeared shrunken and brittle - but biopsies from previous days were fine using above reagents from the same lot number.  Any experience or thoughts regarding this issue would be appreciated.   
Thanks,  Tracey
