Opis: Chromolith® DIOL columns are useful as an intermediate polarity media between C18 and silica. Diol functionalised media is less polar and can have different selectivity. Chromolith® DIOL can be used with a wide range of solvents in both normal and reverse phases. In normal phase mode, the diol phase provides an alternative selectivity compared to silica whilst additionally demonstrating longer retention times that help to obtain separation. In reverse phase mode, compounds such as water-soluble vitamins, sugars or amino acids are easily baseline separated using simple mobile phases. Chromolith® DIOL columns have long lifetimes within pH range of 2,5 to 7,5, high matrix tolerance and speed of analysis.

Opis: Water-free mounting media, such as Neo-Mount®, should be used for permanent mounting and long-term storage of samples. Slides processed in pathologyl laboratories need to be stored up to 10 years, whereby the staining results need to be stable and fading-out is not acceptable. Neo-Mount®, anhydrous mounting medium for microscopy is an extremely colour-stable mounting medium for microscopy, which is produced with solvents based on mixtures of aliphatic hydrocarbons. It contains an aromatic-free substitute for xylene, thus, Neo-Mount® needs to be combined with Neo-Clear® exclusively. Xylene must be avoided in the mounting step, as it will cause the slides to become cloudy and streaked. In addition, by placing the dehydrated slides on filter paper for approx. 1 minute prior to mounting, any excess Neo-Clear® should be circumvented, as air bubbles might arise under the cover slip. The same pre-condition should also be met when mounting specimens using cover slip machines; in this area, Neo-Clear® can be most efficiently eliminated by incubating the slides for 1 minute in an empty slide rack.
