In histology labs, a very common procedure is the tissue sampling, processing and staining. This is a very common and delicate process that needs to be done in the proper way, in order to not compromise the lab results. Tissue processing is about the diffusion of substances into and out of porous tissues. The diffusion process happens when you process reagents to equal concentrations inside and outside tissue blocks.
When processing a sample, you need to take into consideration several variables such as the temperature. In the histology laboratory, the tissue processing describes the stages where the sample goes through dehydration and clearing and then goes through the tissue embedding process. Most of the time, tissues are most conveniently processed through dehydration, clearing and infiltration stages automatically.
The paraffin embedding procedure is a very common one in any histology lab. This is the standard method to produce blocks of tissue for section cutting. Usually, this procedure is performed using an embedding center, surrounding the tissues by a medium such as paraffin wax, which when cooled and solidified will provide sufficient support for section cutting.
Temperature, pressure and vacuum and agitation are very important factors that can affect the tissue processing technique. For example, you can avoid high infiltration temperatures because marked tissue shrinkage and hardening by maintaining embedding waxes 2-3°C above their melting points. On the other hand, high pressure facilitates infiltration of dense specimens with the more viscous embedding media. Finally, tissues agitation during processing ensures an adequate fluid exchange and in automatic tissue processors, continual motion of tissue containers and flow of processing fluids is maintained.
This model features fully programmable computer controls that allow automatic system start and stop at any time (weekly). It has an automatic memory and restoration functions: After startup, all preset temperature data are automatically stored in the system. This tissue-embedding center has five heated areas, including Paraffin Chamber, Paraffin Dispenser, left and right Thermal Storage Compartments, and heating plate (working area); they are individually controlled and work independently without interference from each other. In addition, it has a flexible heating mechanism that overcomes the shortcomings of traditional technology resulting in excessive temperature differences. System provides fast heating and precise temperature control. Moreover, the dual-protection from overheating is safe, reliable and energy saving. The cryo module working temperature is ≤ -20°C. Its temperature control precision is ±1 %. Finally, its dimensions are 560 mm × 550 mm × 385 mm (W×D×H) and its net weight is 35 Kg.
