Solvent Rinsing

Washing glassware with minimum solvent rinsing

Problem: A) You want to rinse out organic residues from glassware and are using a lot of solvents. B) Some tarry residues may be very difficult to rinse out
Solution: A) Use a squirt bottle with the smallest practical tip opening, and use multiple rinses. Second rinses may be poured into unrinsed glassware to get double use from the solvent. B) Combusting the glassware in a furnace at 450-500 °C will eliminate the residues with no solvents or labor. Run a full load for greatest efficiency, perhaps on a given day of the week.
Cost: A) A little extra time may be needed. B) None if muffle furnace is available. Electricity will be needed to run the furnace.
Benefit: Reducing solvents eliminates the energy and resources needed for their manufacture and air emissions.
