Tissue processing and paraffin embedding of specimens

Paraffin embedding of specimens

It depends really on the size of the cartridge you want to use, small samples will fit a roughly measured 5mm dept, 27mm wide, 40mm long cartridge.  Larger cartridges have a 10mm depth, with the other dimensions remaining the same.  Usually 10-15 large cartridges can fit into a basket.

For paraffin embedding samples should be collected and stored in 4% Paraformaldhyde short term.  For long term storage in 70% ethanol is recommended. 

Parrafin embedding processing in the BSI, EM prep lab G.16

1.       Dehydration and permeation in molten wax in the Histokinett

(All automated, usually processed 10-15 samples on an overnight cycle 21hrs duration)

2.       Wax blocking of samples on Tissue tec

(Manual, processing is not difficult, need 2hrs max to process 10-15 samples)

3.       Sectioning of samples on rotary microtome

(Manual, processing can be difficult especially in warmer weather, need a few days to section 10-15 blocks, depending on your method of sectioning)
