Choosing the Right Extraction Media

The Complete AFS Blend Selection & Compatibility Guide

In hydrocarbon extraction and botanical color remediation chromatography (CRC), one variable dictates the difference between a pristine, terpene-rich golden extract and an over-scrubbed, stalled-out recovery run: matching the right filtration blend to your incoming biomass.

Every harvest presents unique challenges. Fresh frozen whole plant requires delicate touch to pull water-soluble hues without stripping volatile monoterpenes. Aged, ambient-stored trim demands an aggressive adsorbent matrix to bind deep oxidation, polyphenols, and heavy carotenoids.

Using the wrong media profile leads to two common lab failures:

  1. Under-remediation: Breakthrough of dark red/amber oxidation pigments.

  2. Over-stripping: Stripping light, aromatic terpenes and producing a flat, flavorless profile.

The following guide and blend selection matrix break down the chemistry, biomass targets, and flow characteristics of each AFS pre-packed filter blend to help extraction technicians dial in clarity, yield, and throughput.

AFS Color Remediation Blend Matrix

Blend Name Target Input Biomass Pigment / Impurity Target Terpene Retention Recommended Run Temp Relative Flow Rate
Light Blend Fresh Frozen, High-Grade Cured Flower, Indoor Sugartrim Anthocyanins, Light Chlorophyll, Trace Moisture Maximum (90%+ Retention) -40°C to -20°C Fast
Medium Blend Mid-Grade Greenhouse, High-Terpene Outdoor, Clean Trim Carotenoids, Chlorophyll a/b, Lipids, Polar Phenolics High (Balanced Profile) -30°C to -10°C Moderate
Heavy Blend Dark/Old Cured Biomass, Highly Oxidized Trim, Amber Resin Runs Heavy Polyphenols, Degradation Pigments, Brown Oxidized Carotenoids Moderate (Polishing Focus) -20°C to 0°C Standard
Reform Blend Off-Spec Crude, Over-Extracted BHO, Salvage Runs Severe Oxidation, Pyrene / Char Byproducts, Dark Tar Low (Scrub/Clarity Priority) 0°C to 20°C (Room Temp) Standard
Zeoclear L / Zeolite High-Moisture Fresh Frozen, Biomass with High Water Content Emulsified Moisture, Polar Color Bodies, Water-Soluble Tannins High -50°C to -20°C Fast to Moderate
Economy Blend Bulk Commercial Processing, Cost-Sensitive Distillate Prep General Carotenoid Scrub, Basic Particulate Clarification Moderate -20°C to 10°C Fast

 

Detailed Breakdown of Each Blend Profile

1. Light Blend — Preserving Terpene Integrity in Top-Tier Resin

  • Best For: Live resin, sauce/diamonds, and high-grade indoor cured flower.

  • How It Works: Formulated with a low surface-acidity rating, Light Blend targets water-soluble anthocyanins (red/purple hues) and minor chlorophyll spikes without isomerizing or adsorbing light, delicate terpenes like myrcene, limonene, and pinene.

  • When to Select: Use when the biomass is already high quality and only requires a polish to achieve a transparent, golden-champagne hue.

2. Medium Blend — The Daily Workhorse for Commercial Trim & Greenhouse

  • Best For: Standard cured trim runs, mixed outdoor batches, and high-volume commercial production.

  • How It Works: A balanced synergy of neutral-to-acidic activated clay and synthetic silica gel. It captures moderate chlorophyll loads and carotenoid (orange/yellow) bands while maintaining high hydrocarbon throughput.

  • When to Select: The default starting point for unknown biomass or standard cured material where color correction and full-spectrum terpene preservation must remain evenly balanced.

3. Heavy Blend — Aggressive Remediation for Aged & Oxidized Biomass

  • Best For: Older material, warm-stored outdoor biomass, and amber-tinted extracts.

  • How It Works: Utilizes higher-activity acid-washed clays and an integrated carbon polishing tier to irreversibly bind dense polar degradation products and oxidized phenolics.

  • When to Select: Whenever incoming solvent washes show deep brown, red, or dark amber tint that standard bleaching clays cannot break.

4. Reform Blend — Remediation and Salvage Filtration

  • Best For: Remediating rejected off-spec batches, re-running crude extracts, or cleaning up char/burn pigments from mechanical system failures.

  • How It Works: Maximum-strength adsorbent power designed for heavy stripping. It aggressively scrubs dark organic pigments, leaving behind clarified, neutral-colored baseline oil ready for further refining or crystal crashing.

  • When to Select: When input color is too dark for market sale and clarity is the primary operational objective over raw terpene preservation.

5. Zeoclear L (Zeolite Series) — Moisture Control & Sub-Zero Processing

  • Best For: Fresh frozen runs exhibiting high dissolved moisture content.

  • How It Works: Engineered around synthetic molecular sieves and porous aluminosilicate chemistry, Zeoclear L traps micro-droplets of water and polar moisture bonds before they can blind the clay bed or cloud the collection pot.

  • When to Select: Running cold fresh frozen where ice thawing causes solvent haze or creates emulsion layers in the extraction loop.

Technical Recommendations for Running Pre-Packed AFS Cups

  1. Nitrogen Assist Pressure: Maintain between 60 and 100 PSI differential pressure across the housing to preserve steady laminar flow and eliminate gas blowout.

  2. Temperature Matching: Always chill your filter housing inline with your solvent loop. Passing warm solvent through a cold filter cup (or vice versa) can cause thermal shock and channel bypassing along housing walls.

  3. Capacity Thresholds:

    • 2.5" Cup: Recommended for 5 to 15 lbs of biomass (depending on pigment density).

    • 4" Cup: Recommended for 20 to 50 lbs of biomass.

    • 6" Cup: High-throughput skids running 75+ lbs per cycle.
