    Hochstrom Paper Package

    Original price was: $850.00.Current price is: $769.99.
    Stage 1 - 1000pcs of 20u chemical duty paper. Stage 2 - 1000pcs of 8u chemical duty paper. Stage 3 - 500pcs of sub 1u chemical duty 100% borosilicate paper (no chemical binder grade AE). These circular papers have a 142mm diameter (5.6 inch). All papers made in USA with no questionable composition, and no import junk. Straight up, best high flow papers you’ll ever use.
    • Comes with steps 1, 2 & 3 Hochstrom Filter™ high flow paper
  • Hochstrom O-rings (2 included) that fits at the bottom of your Hochstrom filter™. Made from Viton, a synthetic rubber and fluoropolymer elastomer, that is chemical-resistant. 100% USA made.
  • The Hochstrom Filter™ is the industries highest free flowing filter with Lifetime warranty and the LAST FILTRATION APPARATUS YOU WILL EVER BUY. No more glass, no more broken or chipped frits and absolutely no warped or low end plastic/ceramic units. 100% made in the USA and built to outperform anything on the market. Comes with dual O-ring seals that stay lubricated for smoothly securing the papers. With aerospace grade parts, this patented filter system has the highest flow on the market with ring seal technology. This is absolutely no joke when we say, this is the last buchner filter you will ever buy, capable of speeds unprecedented for its size. This filter comes with bottom (male thread) and 1/4 barb nipple, stainless mesh, stainless ring, viton O-rings (2) and tall tube (female thread). PDF Diagram Various micron sizes of Hochstrom papers: Hochstrom Stage 1 Paper Hochstrom Stage 2 Paper Hochstrom Stage 3 Paper Hochstrom Paper Package
  • This is an additional package to the original Hochstrom high flow filtration unit. It comes with one plate, one ring and one tall tube cut for dual plate arrangement (The cut is double sized to allow two plates). Adding another plate will refine your product even more and save you that extra run, thus cutting your time in half. The original Hochstrom Filter ™ comes with single plate arrangement. Hochstrom threaded base, nipple and viton O-rings not included.   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 dual plate kit is the last filter you will ever need to buy. Summit Research, only the best.   https://youtu.be/_F65D3Skmj0 100% made in USA.  100% Billet machined for exacting fit.

    Simple yet powerful, the GVS40A uses displacement and horsepower to achieve CFM. Unlike many other types of pumps that require complex fore traps, cryotraps, etc. – a well maintained single stage rotary vane can withstand great amounts abuse; making them very affordable and usable without much worry. Also know as 'roughing', 'wet' or 'backing' pumps. The GVS40A rotary vane pump is required for any sized hard-piped system and can be very useful on hosed systems as well.

  • Summit Research Fraction Finder figures out where components start and stop flowing to optimize separation. Making the short path distillation process more precise and repeatable, Fraction Finding takes the guess work out. Someone running a distillation can make better decisions if they knew exactly where they were in the distillation process. Scientists have developed expertise in this area to the point where they know what to expect. The Summit Research Fraction Finder does exactly that and will be your best friend in your laboratory. Included with:
    • #29 Standard sensor
    • Mounting hardware
    • Display screen
    • Light-blocking tape
    • Power Supply
    • Sensor Cable
    • User Manual and Quick Start Guide
    • 1-Year Warranty
    Through innovative live distillate monitoring, Fraction Finding can help increase potency on every distillation pass. Now, you can forget the old ways of relying on guesswork and eyesight, and instead, identify the contents of a flow through a glass tube in real time. Simply mount the #29 sensor on your distillate collection port and let the Fraction Finder do the rest! Please contact Summit Research if you want to upgrade to the Ultra-Sensitive Fraction Finder. This new version can now be utilized on chromatography separations as well as your normal distillation processes. We now include FREE ATHENA SOFTWARE for download (Fraction Finder compatibility) More videos and conversations on our Instagram https://youtu.be/IPJVbMJlU_0

    Frequently Asked Questions

    Which fractions can the Fraction Finder detect? During short-path distillation, it can distinguish what is colloquially known as “Heads”, “Main Bodies”, and “Tails”. Click here for a list of molecules, such as Delta-9 and more. What units of measure does the Fraction Finder digital readout use?  The system uses Nanometers (nm) and Intensity (au). Can the Fraction Finder sensor fit on size 24 glass? If you have size 24 glass, order our 24/40 adapter, which can fit a size 29 sensor. Sensor #34s are available. What heat can the Fraction Finder sensor handle? The Fraction Finder sensor can handle around 100 degrees Fahrenheit. If you plan to exceed these limits, order one of our Hot Tech Adapters. Does the Fraction Finder work the same as an HPLC? Both systems use spectroscopic analysis to identify chemicals. However, the type of spectroscopy that detection method and wavelength regime are different. The Fraction Finder operates uses fluorescence, whereas HPLCs utilize absorption.
