Isopropanol as Clearing Agent
Isopropanol is well suited as clearing agent for paraffin-embedding, because it is compatible to melted paraffin: After dehydrating with isopropanol the sample is incubated in a mixture of isopropanol abs. and paraffin (1:1) at approx. 60 °C. After a further incubation step with pure paraffin, the sample is embedded as usual.
This method is particularly suitable to smooth organs. Since embedding can start immediately after alcohol step, the working process is shortened significantly.
2-Propanol ROTIPURAN® ≥99,8 %, p.a., ACS, ISO
Acid Value Determination
The acid number characterises the acidic components of the fats. For this purpose, the sample is dissolved in a solvent and titrated against phenolphthalein with potassium hydroxide solution. Only free fatty acids are recorded. The fatty acids bound in the glycerides are not determined.
