Sorry, this product is not available

Special Features

  • DESIGN---- This solvent still head is designed with a syringe port with 4mm PTFE stopcock and 14/20 outer joint for solvent transfer via the syringe.With a side tube path from neck under top outer joint to the tube on the lower inner joint.With two 0-4mm high vacuum valves to control the flow direction of the solvent from the still head.
  • USE-----The solvent still head is used for distillation and collection of oxygen free solvents.It uaually used with a distillation flask (round bottom flask with 24/40 joint,the capacity should be larger than the still head),a jacketed reflux condenser(liebig,graham,allihn,coiled,reflux),a vacuum or inert adapter to connect a vacuum or inert gas source from schlenk line through an oil bubbler,a rubber septum,a receiving vessel(erlenmeyer flask, flat bottom flask with 14/20 joint).
