[Histonet] Frozen Sections Falling Off Slides

Although it should NOT be the cause, I always used my cryostat at -20 to -25ºC Second I always warmed the slides (at least 30ºC) before picking the sections. This requires having a well extended cryosection and to pick them up with a "smooth movement". You will not have any chance of "rearranging-extending" the section.
As a fixative I used NBF for 30 seconds → to regular or special staining.

Hello histonetters!!!Im presently using the Tissue Tek Cryo3 Frozen section Machine...But i dont understand why i got problems sections falling off slides.I used different types of slides non adhesive,adhesive(poly l lysine,thermoshandon,starfrost sakura)..Regular procedure : Sections taken from 2-4 microns,transfered to 95% alcohol fixative, wolfsgang fixative etc..then after distilled water wash out...sections started to peel off...My machine setting- chamber is -30 C;cryochamber is -39 C..example of tissue- fibroma and salivary gland...
I used Leica cryostat previously but i never got these problems...Even i used non adhesive but sections still on the slides..Can someone advised  please.Maybe youre using the same tissue tek cryo 3...
