Developed for the concentration of trace amounts of sample dissolved in organic solvents

Models with [ST] 14/20 joints are graduated from 0–1mL in 0.1mL divisions. Models with [ST] 19/22 joints are graduated from 0–1mL in 0.1mL divisions and from 2–10mL in 1mL divisions. Models with [ST] 24/25 joints are graduated from 0–1mL in 0.1mL divisions and from 2–25mL in 1mL divisions.

Caution: If solvent is allowed to escape, the entire assembly should be set up in a hood.

Useful in sample preparation before analysis with solvents such as petroleum ether or hexane. Concentrators have columns designed to speed evaporation with reduced hold-up.
