Contract Manufacturing

Nova offers a variety of services on a contract manufacturing or toll basis

Vacuum Distillation

We are the only service provider with continuous distillation of high boiling point solvents. See below for a representative list of solvents and oils that can be purified. Our equipment can generate vacuum down to 50 torr and temperatures up to 280C.

All contact services are 304 SS or PTFE (high temp fluoropolymer).

  • Batch Size: 500 gallon minimum
  • Flashpoint: above 39C
  • Solvent mixtures can be split into three streams (low boiling, point, high boiling point fraction and a middle condensate fraction).
  • Inert atmosphere available with nitrogen or argon purge (to prevent oxidative decomposition of sensitive oils)
  • We do not accept halogenated solvents
