Premium CRC and filtration media for cannabis and botanical extraction labs — remove color, pigments, and impurities to produce the cleanest possible extracts.
The right media in the right column at the right stage makes the difference between a good extract and a great one. Our team can help you select and sequence the right products for your specific process and target outcome.
Request a QuoteColor remediation column (CRC) technology uses stacked adsorbent media to remove chlorophyll, pigments, pesticide residues, heavy metals, and unwanted lipids from hydrocarbon and ethanol extracts. The type and quantity of media you use determines the final color, clarity, and purity of your concentrate.
Our Strainer S1 is standard-flow granular CRC media suited for high-throughput systems and standard-quality biomass. Strainer S2 contains approximately 1.5× the silica content — more aggressive, better suited for aged, dark, or high-moisture biomass. The M-variants (S1M, S2M) are finer-grain for medium-flow, higher-pressure systems.
All Strainer products are ready-to-use directly from packaging — no pre-baking, pre-drying, or activation required.
A general guideline is 150–250 grams per 1 lb of biomass — less for high-grade biomass, more for aged or lower-quality material. Full loading rate tables are available in the TDS sheets for each product.
Most media can be reused across multiple runs, though efficacy decreases with each cycle. Flush with pure solvent between runs to recover yield. Replace when your target output quality is no longer achieved. Consult the SDS for disposal guidance.
