short path distillation

  • KF16 to 1/4 Barb Adapter needs a KF16 Centering Ring and clamp. Stainless steel barb used for vacuum hose transitions. Summit has other KF16 items in our Vacuum Parts section. Summit recommends these items for this product:
  • AV 10k airvalve KF breather valve. 100% USA made. In conjunction with: Or get them all together in the Breather Valve Kit
  • Fits Size 29 or 34 Fraction Finder Sensor (drop down menu) Details:
    • Goes in-line between the condenser & collection flask, allowing you to use the Fraction Finder in a new location and still run a hot condenser.
    • High temperatures can be problematic for our sensor; this relocates where Fraction Finder could be positioned.

    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
  • 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.

  • The Fraction Finder Ultra Sensitive figures out where components start and stop flowing to optimize separation. Making the SPD Process more precise and repeatable, Fraction Finding helps take 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 that for you and will be your best friend in short path distillation. Included with:
    • Ultra Sensitive 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. The Fraction Finder Ultra Sensitive package is unique in that - not only does it serve distillation and extraction processes - but also serves Chromatography, Conversion Reaction, and other processes that require more extreme detection. For certain processes, highly sensitive process monitoring is essential. Generally speaking, the more solvent involved in the process means the more sensitive the sensor needs to be. With that in mind, the ULTRA was created. If you have the original Fraction Finder, you have the option to upgrade to a standalone ULTRA Sensor for $1,350. Please call us for more details. Use this sensor on any chromatography column with the GL18 to #34 adapter. The Fraction Finder Sensor #34 consists of an optical light pulse and detector, acting as “the eyes” of the system. It wraps around a distillation/chromatography setup tube and connects to the Fraction Finder display to track important data on the process.
    • Fraction Finder optical sensor with ultra-sensitive detector
    • Magnetic locking mechanism
    • Anodized aluminum apertures
    • 90° strap rotation
    • Currently only available in size 34
    • Validated by Arometrix for use on distillation systems
    • Currently being tested on reverse-phase chromatography processes
    • Display and sight glass not included

    Information common with all Fraction Finder sensors

    These sensors are black for a reason:
    • Black absorbs all light while blocking out ambient light.
    • This leads to better signaling and the most valid data possible transmitting to the Fraction Finder display.
    • For example, a white sensor wouldn’t work because it would reflect the light into your glassware and into the sensor, harming the reading.
    Chemical Resistant
    • This reduces any degradation from solvents, crude oils, extracts, etc..
    • This protects the sensor and ensures that it lives to see an endless amount of runs.
    Thermo Resistant / Safety
    • The black coating we use on each sensor is a high temperature, thermal resistant coating, it can withstand temperatures well above anything you’d see in a distillation lab.
    • It’s nearly impossible to set one of our sensors on fire, the coating is almost completely fireproof!
    • This protects the user, the equipment, and (in worst case scenarios) the entire lab.
  • 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.

    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.

    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.
