Cassette range is usually important. You may see that I have a picture here highlighting several different types of cassettes. Importantly, when picking a cassette, guarantee there’s adequate space in that cassette for fluid penetration all through the tissue.
c) Baskets may be optimized for maximum cassette numbers by intently packing the cassettes or for optimum reagent flow by leaving Area concerning cassettes.
Diligently transfer the mildew and cassette on to the great plate and permit time (a minimum of 15 min) till the paraffin has hardened.
Examine that the various compartments of your station have the right temperature. Paraffin need to be liquid inside the paraffin reservoir, perform floor really should be warm, and funky plate ought to be chilly. Stainless-steel molds must be stored heat.
