AW: [Histonet] hard vs. soft paraffin

[Gudrun Lang]

The melting point usually depends on the length of the paraffin-chains. In
the datasheet of paraffins, you will see something like C20-C35 for a
melting point of 52-58°C.

Betreff: [Histonet] hard vs. soft paraffin

What constitutes "hard" paraffin vs. "soft" paraffin?  Is it just melting
point?  What are the characteristics of hard and soft paraffins?  How does
water bath temperature play a role?  Which is preferable for avoiding
compression of tissue?

thanks,
Clare
