  • HEAVY WALL ---This schlenk flask is heavy-wall designed , made by hand-blowing according to ASTM E438 ,made of high-quality borosilicate glass and annealed at 800 degree Celsius ,can be heated directly in an open flame and can withstand typical laboratory thermal variations in Chemistry processes like heating and cooling,durable and reusable.
  • DIMENSIONS----This pear-shaped schlenk flask,modified schlenk tube, capacity of 10mL,with 2mm glass stopcock which is easier to clean and won't leach grease into your reaction mixture.With 14/20 top taper outer joint allowing material to be added to a flask or attaching a reflux condenser for reaction.
  • USE----Schlenk flasks are indispensable laboratory glassware used in air-sensitive chemistry to conduct air-sensitive reaction.Comparing to non-air-sensitive reactions reaction, this schlenk flask features a glass stopcock connecting with a schlenk line and controlling the access to inert gas or vacuum. In a reaction setup,the schlenk flask may use with an addition funnel,reflux condenser,magnetic stirring shaft and bars.For filtration,a schlent frit is required.
  • DESIGN----This Kjeldahl shape schlenk flask consists of a pear-shaped flask facilitates heating and stirring.It has a sidearm fitted with a glass stopcock connecting to a vacuum or inert gases source.The top ground glass joint is used to attach the flask to other lab glassware apparatus ,or stopped by a penney head stopper,rubber septum,permitting easy transfer of liquids or solids.
