Diazomethane Generator With Standard Taper Clear-Seal ™ Grease-Free Joints ■ Used to generate diazomethane and other gases for gas chromatography, mass spectroscopy and NMR studies using one millimole of Methylnitronitrosoguanidine (MNNG) ■ Features Clear-Seal ™ grease-free joints that have never been ground and does not require an “O” ring ■ Includes a plastic standard taper joint clamp, a 13-425 screw cap with cut-out top and a PTFE faced rubber liner ■ Manufactured from WHEATON 33 low extractable borosilicate glass that conforms to ASTM E 438 Type I, Class A requirements ■ Note: Please use a safety shield and efficient fume hood when generating diazomethane or similar gases
Micro Soxhlet Extraction Apparatus With the WHEATON Connection ® ■ Used for continuous extraction of analytes from a solid into an organic solvent ■ WHEATON Connection ® eliminates the need for hooks, springs and clamps common to standard ground joint designs ■ As the flask containing the solvent is heated, vapors rise in the larger outside tube, enter the water-cooled condenser, and liquate ■ When the liquid level in the extractor reaches the top of the bent tube, siphoning action returns the extract- enriched solvent to the flask ■ Wetted parts are manufactured from either WHEATON 33 low extractable borosilicate glass that conforms to ASTM E 438 Type I, Class A requirements or PTFE
