Lowicryl K kits are polar and therefore hydrophilic. During dehydration and infiltration specimens may be kept partially hydrated since polymerization can occur with up to 5% water. Thus immunolabeling with polar kits results in better preservation of structure and antigenicity and lower background labeling.

Lowicryl^® HM kits are non-polar and are used to produce high contrast images of completely unstained thin sections by Z-contrast. Also these HM kits are particularly suitable for dark field observation because of their relatively low density.
