joint: ST/NS19/22 Clear-Seal joints

The mini Diazald apparatus bridges the gap between the System 45 diazomethane generator Z411736 (for preparing <1 mmol of diazomethane) and the Diazald kit (for preparing ~100 mmol of diazomethane). It consists of a reaction vessel and a condenser in one compact unit. This apparatus features a cold-finger in place of a water-jacketed condenser. When filled with dry ice/acetone slush, the condenser efficiently prevents dangerous diazomethane/ether vapor from escaping. A separatory funnel, Z100382 and a round-bottom receiving flask, Z100358, (must be equipped with Clear-Seal® joints) are the only other glassware needed and can be purchased separately.

NOTE: Sigma-Aldrich is unable to supply certain Diazomethane precursors in some countries. Check availability of starting materials prior to glassware purchase.
