PR-O™ Suggested Use Link SOP

PR-O

Standard Operating Procedure (SOP)
PR-O™ is compatible with all processing solvents. It’s suggested for in-line CRC applications or vessels that accept granular carbon. The minimum recommended amount is 10% m/m of estimated extract in solution.
Safety: Please adhere to the safety and handling instructions in the PR-O™ Safety Data Sheet (SDS), included with your shipment, available at mediabros.store, or by emailing sales@mediabros.store.
Required Materials:
  • PR-O™ Filtration Media
  • In-line Filtration Housing & Filter OR CHROMATOGRAPHY COLUMN
    • CRC Column Size: For best results, use a 4–6 inch diameter column.
    • Filter: Optimized for use with a ≤5-micron screen filter followed by a 0.2-micron, Media Bros Ulti-Filter.
Recommended Conditions:
Solvent-to-biomass ratio: 6:1 to 10:1
Operating temperature: Below -10°C, will not clog due to ice
Flow rate: < 1 GPM. A needle valve or flow restrictor at the column base improves flow control.
Procedure:
  1. Determine your ratio. For every pound of biomass, load 100–200 grams of PR-O™ into the filtration housing. The exact amount depends on biomass quality and desired outcome. Refer to the quick reference table:
    PR-O™ (Media Use Based on Grade)
    Plant Matter Low Grade Medium Grade High Grade
    1 lb 200g 150g 100g
    2 lbs 400g 300g 200g
    5 lbs 1,000g 750g 500g
    10 lbs 2,000g 1,500g 1,000g
    15 lbs 3,000g 2,250g 1,500g
    20 lbs 4,000g 3,000g 2,000g
    25 lbs 5,000g 3,750g 2,500g
    30 lbs 6,000g 4,500g 3,000g
    50 lbs 10,000g 7,500g 5,000g
    100 lbs 20,000g 15,000g 10,000g
  2. Secure filter screen and media. Ensure the filter screen is safely installed. A cloth or paper filter may be combined with a screen or plate. Load media directly into the column on top of the filter screen.
  3. No pre-wetting required. PR-O™ is designed to be used dry.
  4. Run extraction using a POLAR OR NON-POLAR SOLVENT. Any lost yield can be recovered by flushing the media with pure solvent.
  5. Disposal. Follow all SDS instructions for safe disposal.
