  • 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 807 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 round bottom flask is designed with 2mm glass stopccok on side-arm ,with 19/22 standard taper joint,which can be stopped by a glass topper or 14# rubber septum.Capacity of 250mL.
  • USE----This schlenk flask with glass stopcock is usually used as a reaction flask in air-sensitive chemistry.The 8mm glass stopcock connects to the schlenk line allowing the flask to be evacuated or filled with gases (usually inert gases).The taper joint at top permits easy transfer of liquids or solids,it may attach an addition funnel ,reflux condenser, magnetic stirring shaft, vacuum flow control adapter to assemble a reaction setup.
  • DESIGN----This schlenk flask is comprised of a single neck round bottom flask which can be heated directly in an open flame or heating mantle,ideal for reflux reaction in air-sensitive chemistry.With 2mm glass stopcock having a constant pressure retention device.With a standard taper joint on the single neck attaching to lab glassware for adding ,transferring or reflux.
