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
