A well-designed recycler can recycle a solvent forever!
Solvent used for tissue processing or staining becomes contaminated with stain, water, fat, protein, wax, and biological materials during use.
The recycling process removes these contaminants from the good solvent. Reuse of the solvent is unlimited since it is brought back to the original purity each time it is recycled.
A well designed recycler removes all of the contaminants during the recycling process.
Each time you recycle a solvent, the contaminants should be completely removed and the clean solvent is put back into use. This allows you recycle and reuse your solvents indefinitely.
Choose a solvent recycler that comes with a guarantee that you can recycle your solvents forever. If you see a recycler that does not come with a guarantee, you will want to keep looking.
