Kuderna Danish Concentrator

500mL Flask, 24/40 Top, 19/22 Bottom

…two joint springs. If further concentration is desired, select a 2-Ball column (21582CO) and combine with the KD tube of your choice. The 250mL and 500mL completes include a 10mL tube. The 1000mL complete includes a 25mL tube. Jacketed Kuderna-Danish concentrator tubes circulate hot water through…

For concentration of materials in volatile solvents. Combines rapidity, simplicity and quantitative efficiency including minimization of entrainment escape and transfer losses. Available in 250ml, 500ml, 1L flasks, with a 19/22 inner joint on bottom of flask, 24/40 on top. Choice of Snyder or…

These 500mL PYREX® Kuderna Danish Concentrators are supplied with Keck clamps instead of spring hooks. The complete apparatus consists of a 3-Ball Snyder column (with 24/40 Standard Taper joints), a 500mL flask (with 24/40 Standard Taper top and 19/22 Standard Taper lower joint), and a graduated…

…evaporators have a broad range of applications including concentrating extracted materials from Soxhlet operations and other KD evaporation methods. At each sample position, the KD flask rests on the bath cover disk and the concentrator tube sits partially submerged in the deep water bath below…

Graduated concentrator tubes for use with Kuderna-Danish evaporative set-ups. Tube can be stoppered for storage. Overall height is 100mm for both the 4 and 10mL, and 170mm for the 25mL. Available with and without hooks.

Use with Kuderna-Danish and other concentrators. May be stoppered for analysis or storage.

…for the concentration of trace amounts of sample dissolved in organic solvents. The column is designed to speed evaporation with reduced hold-up. It is very useful in sample preparation before analysis with solvents such as petroleum ether or hexane. Graduated concentrator tube 570035…

Developed in the laboratories of Julius Hyman and Company for the concentration of trace amounts of sample dissolved in organic solvents. It is very useful in sample preparation before analysis with solvents such as petroleum ether or hexane. Preparation involves filling the flask to between 40…

Graduated concentrator tubes for use with Kuderna-Danish evaporative set-ups. Tube can be stoppered for storage. Overall height is 100mm for 10mL, and 170mm for the 25mL.

Optional concentrator tube for use with Kuderna-Danish and other concentrators. May be detached from the complete assembly and stoppered for analysis or storage. Secure to assembly with 662750 springs or 675300 polyacetal clamps, not supplied.

Lower body of flask has a hemispherical shape to afford continuous flow of heavier fractions to concentrator tube during reflux. Top joint is a 24/40 outer while the lower joint is a 19/22 inner. Available with and without hooks on the lower 19/22 inner joint.

This three-position linear solvent recovery system is intended for use with Kuderna Danish evaporative concentrators. Heating mantle, controller, splash guard, clamps and supports provided with the complete system Power: 15 amps – 120 volts Refrigerating circulator recommended…
