Dear Kimberley,
We used to use a Linistainer in my previous lab, we didn't have problems
with sections coming off but then we did always dry  the slides in a 60oC
oven for about 15 mins prior to putting them on the stainer.
Personally I loved the Linistainer much preferred it to the Varistain
which is what we have now.
By the way , on the subject of duplicate messages, I haven't had ANY, I
am obviously one of the lucky ones ! .
