…pollutants prior to instrumental analysis Includes a two- or three-ball Snyder column, a flask and a spring-mounted collection tube for convenient access to samples Complete apparatus consists of a Snyder column 150 mm long (with Standard Taper 24/40 joints), a flask (with Standard…

…Taper top and 19/22 Standard Taper lower joint), and a graduated 10mL tube with an outer 19/22 Standard Taper joint. The tube graduations go from 0 to 2mL in 0.1mL increments and from 3mL on in 1.0mL increments. All columns have venting dimples. For replacement Snyder columns, see No. 2158-3CO.

Floating ball type, 24/40 joints, each section is approximatly 51mm long.

…to circulate through the 1 liter sample bottle continuously until the extraction is complete. By incorporating a stop-cock assembly and 3-ball Snyder column, the Corning One-Step extractor can both extract desired analytes as well as evaporate solvent from the end by-product within the same cycle. …

…the concentrator tube sits partially submerged in the deep water bath below the cover disk. The solvent boils from the flask and through the Snyder column. The solvent vapor then cools in the condenser which is attached to a centrally located water manifold. The glassware is held in place with quick…

…system be used above or near the units in case of a drop in condenser water temperature or loss of condenser cold water supply. Removable Snyder column sidearm allows easy cleaning.  The required concentrator tube (1234B38 or 1234B39) and the Allihn condenser (4406K40) must be purchased…

…joints eliminate the need for grease, reducing the possibility of contaminating the sample Complete unit consists of 270mm three-ball Snyder column, 500mL flask and 10mL receiving vessel Manufactured from WHEATON 33 low extractable borosilicate glass that conforms to USP Type I and ASTM…

When attached to the top of Snyder Column, unit is designed to recover solvent normally lost during Kuderna-Danish Evaporative Concentrations. PTFE stopcock (1:5, 2mm bore) provides option for total reflux or takeoff. #7 Ace-Thred on side arm accepts tubing 6 - 7mm O.D. 5029-10 Nylon bushing and…
