Vacuum Aspirator - Methoxide Injector Strong Vacuum - Lifts Liquids above 1.5m Making biodiesel can be potentially dangerous, methanol is toxic and sodium or potassium methoxide is both toxic and corrosive. Eliminate your risk of exposure to methoxide by installing a vacuum aspirator into your biodiesel reactor. The flow of liquid alone creates a one way vacuum, sucking methoxide (or any liquid) safetly into the reactor. Additional advantages include 1) Rapid feedstock drying by leaving the inlet open, airating the wet         vegetable oil 2) Your pump does not have to tolerate corrosive methoxide, extending its lifespan. 3) Fire risk is reduced, safer environment for the biodiesel operator. 4) Postive pressure created in the reactor, optimising methanol recovery via a condenser. These vacuum aspirators are made from PVDF (Polyvinylidene Fluoride) which is resistant to hydrocarbons and corrosive chemical attack. PVDF is an advanced thermoplastic, used in specialist applications and tolerates a temperature exceeding 150c. Fitted with 3/4" NPS screw threads, ideal for connecting to 22mm pipe work. You can either source a NPS to 3/4" BSP adapter or do what I did in the video and scew into 3/4"BSP with PTFE tape to create a seal.
