Flask has a jacket permitting heating or cooling of the contents.

• The lower half of flask is jacketed
• Half jacketed flask permitting heating and cooling fluid from a constant temperature bath
• The Chem-Drain valve is available in two sizes, 6 mm and 12 mm
• This dimension refers to the straight section of the plunger
• Lower portion of the plunger has a ¹/₂" section for attachment of flexible tubing to allow material to be transferred into a receiving vessel
• The 12 mm size will permit drainage of solids having a diameter to 2 mm, while the 6mm size will allow drainage of solids to 1.5 mm

When closed, the tip of the PTFE plug seals into the lower radius of the flask, avoiding the dead space normally associated with standard stopcock drains.

This feature permits total mixing and drainage of the contents of the flask. When open, the contents of the flask drain through three openings into the main bore of the plunger.
