Kuderna-Danish Concentrators, Graduated, KONTES*
Developed for the concentration of trace amounts of sample dissolved in organic solvents. 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.
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.
