  • The Hochstrom High Flow Filter is the fastest unit on the market. It’s unique design allows it to operate under half vacuum pressure for full flow. Our peers & customers have reported the high flow surface area to be equivalent to a 18-24″ table-top unit. These units have a huge basin, but small holes, really preventing it from being efficient for it’s size. A table top or small buchner filtration unit will have flow issues due to the solution warming up & redissolving past the filtration medium. You also get the fluid rushing around the filter media as well as a large surface area for liquids to warm up. We have achieved maximum efficiency in a much shorter time for filtration. This prevents items from warming up & redissolving and / or not securing. Hochstrom filter is the last filter you will ever need to buy. Summit Research, only the best. 1x Hochstrom Filtration Package Stage 1 - 1000pcs of 20u chemical duty papers. Stage 2 - 1000pcs of 8u chemical duty papers.

    The Short Path Distillation Head FC34 (spd-2 fc34) has been upgraded with our new fraction collector technology. This head runs specifically for smaller setups (2L & 5L). Equipped with #34 bore, #29 discharge arm and #24 key port. All tapers are traditional. When Summit Research initially released the first fraction collector technology we knew it would be a hit. We have innovated the newest distillation technology with the industry leading high-efficiency heads. We have retrofitted all Summit Research heads to incorporate our patented distillation technology. The fraction collector head offers extremely high-efficiency operational parameters unparalleled to anything available on the market. Summit delivers solutions and results to our customers coming from extensive research and design in the field of high speed, high potency, low temperature, consistent distillations day after day. The differences between the FC series heads are the heights. Lower height heads will have less selectivity with faster speeds and lower temps, taller heads will have slower speeds with slightly higher temps with more selectivity. Partnered with our patented laminar path technology and the inverted cup cold trap/hardpipe kits, our customers experience smooth, fast and consistent clarity time after time. This FC34 head holds a medium height and 2 levels of vigreux for medium rejection. A traditional all around head that will stand the test of time. Refer to our instructional (SPD-2 FC34 Complete) for correct setup of this head. GL14s and key included.
