Summit Research SPD-4 MPD HB1 150mm



SOLD in pairs with HB2 150mm!

First of its kind, innovation and performance meet the future of distillation. Gen2 HB series heads are a unique and fascinating technology brought to you first by Summit. Inspired by the original fraction collector technology, we have taken the concepts and technology to a new level with these highly complex and innovative designs. SPD-4 MPD HB1 is made in USA.


The Summit research SPD-4 MPD (modified path distillation) HB1 model was created for one of our testers Breaking Dabs aka Heisenberg. With his unique skills he has helped us tune the Summit MPD series heads to evolve and provide solutions for our users. HB1 is designed to be ultra selective to evacuate all previous fractions before the main body without letting the main body through. With some temp, main body can come out extremely fast and this head can be used as a first pass head. It is very effective in removing heads fractions while retaining main body components. Please contact us for a completely tuned system with this hardware, a consult with Heisenberg can be included if you have a complete setup and sufficient hardware for him to perform his consultation on this series of heads. The HB1 + HB2 150mm series heads come as a pair and are not sold separately. Requirement to use these heads would be a sogevac + dual e2m30 -OR- sogevac + e80 -OR-  sogevac + e80 + diffusion array. This particular setup benefits from a custom diffusion array and an Apollo Vacuum Controller with the inert gas sweeping feature.  Effectively increasing the stock speed and lowering the temperatures further.


SPD-4 MPD HB1 150mm head only. Comes with 100mm clamp, O-ring and 2 PTFE GL14s. #34 discharge port. Our MPD heads fit exclusively to Summit MPD boiling flasks:
