Product Description
Run careful fractional vacuum distillations and collect several fractions without stopping. A vacuum-jacketed Vigreux column holds heat for better separation, and the attached vacuum adapter section feeds a distribution adapter with four receiving flasks for efficient fraction collection. It is designed for researchers who need clean cuts from small batches.
This listing is for Kimble catalog number 287320-0000: KONTES Vacuum Jacketed Vigreux Distillation Head. The vertical column has a standard taper thermometer joint on top, and a stabilizing bar braces it to the vacuum adapter. The adapter takes a 287902 distribution adapter and four receivers, and joints can be held with springs or polyacetal clamps. Joints are 14/20 with a 10/18 thermometer joint; glass is low extractable 33 expansion borosilicate. LIGHT LABS ships genuine DWK Life Sciences products with knowledgeable support from our Englewood, Colorado team.
