CR41™ Suggested Use Link SOP
CR41™
Standard Operating Procedure (SOP)
CRX™ and CRY™ share similar usage and application, however CR41™ is a more advanced
media that excels at removing light pesticides, metals, and excess color.
Safety: Please adhere to the safety and handling
instructions in the CR41™ Safety Data Sheet (SDS), included with your shipment, available at
mediabros.store, or by emailing sales@mediabros.store.
Required Materials:
- CR41™ Filtration Media
-
In-line Filtration Housing & Filter
- 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:
-
Determine your ratio. For every pound of biomass, load 150–250 grams
of CR41™ into the filtration housing. The exact amount depends on biomass quality and desired
outcome. Refer to the quick reference table:

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.
- No pre-wetting required. CR41™ is designed to be used dry.
- Run extraction using a hydrocarbon based solvent. Any lost yield can be recovered by flushing the media with pure solvent.
- Disposal. Follow all SDS instructions for safe disposal.
