Design: round bottom, pear-shaped with a ground glass joint and side arm (PTFE stopcock, glass stopcock, or high vacuum valve)
Usage: for air-sensitive reactions and Schlenk line work, with precise control over vacuum exposure
Material: high-quality borosilicate glass, annealed at 800 degrees Celsius
Craft: heavy-wall designed and hand-blown for uniform wall thickness
Guarantee: Laboy offers a 100% 40-day money-back guarantee on this product.
Description:
This standard Schlenk flask features a round bottom, pear-shaped design with a ground glass joint and a side arm that can be fitted with a PTFE stopcock, glass stopcock, or high vacuum valve. The 2mm PTFE stopcock allows for precise control over the flask's exposure to a vacuum manifold on a Schlenk line, making it an essential tool for air-sensitive reactions.
The glass out joint at the top of the flask is used to add materials, and can be sealed with a ground glass stopper when not in use. When the flask is connected to a vacuum manifold under positive pressure of inert gas, the stopper can be replaced with other apparatus, such as a reflux condenser.
Laboy glass flasks are heavy-wall designed, hand-blown to ensure uniform wall thickness, made of high-quality borosilicate glass, and annealed at 800 degrees Celsius. They can be heated directly in an open flame and can withstand typical laboratory thermal variations in chemistry processes like heating and cooling.
