The Alchemy of Oil

To the uninitiated, July 10th is just another summer day. But to the botanical extraction industry, concentrate connoisseurs, and extraction technicians, 710 (OIL spelled upside down and backward) is a historic milestone. It is a celebration of the shift from raw plant material to highly refined, molecularly isolated cannabinoids and terpenes.

The journey from underground, MacGyver-style open-blasting to modern, C1D1-compliant laboratories, automated closed-loop systems, and advanced Color Remediation Columns (CRC) is a masterclass in rapid technological evolution. At the heart of this history is a relentless pursuit of purity—a path that directly mirrors the innovation timeline of modern extraction filtration.

2010–2014: The "Open Blast" Era and the Wild West

Before 710 became a globally recognized holiday, the concentrate landscape was defined by shatter, wax, and crude "honey oil." In the early 2010s, extraction was largely a dangerous, unrefined science.

• The Method: Extractors packed glass or stainless steel tubes with plant material and literally "blasted" liquid butane through them into open Pyrex dishes.

• The Problem: The resulting concentrates frequently contained high levels of residual solvents, heavy lipids, and dark, bitter chlorophyll.

• The Filtration: Primitive at best. Extraction artists relied on un-rated coffee filters and basic mesh screens to catch heavy plant material.

During this era, extracts were frequently dark, unstable, and harsh on the lungs. The industry urgently needed scalability, safety, and a standardized method to remove undesirable compounds like lipids, waxes, and pigments.

2015–2018: Closed-Loop Systems and the Dawn of Science

As legalization spread, the industry moved from garages to industrial labs. Closed-loop extractors—which recycle solvents in a sealed, pressurized system—became the baseline standard for safety and efficiency.

With closed loops came the ability to utilize winterization (using ethanol and sub-zero temperatures to freeze out fats) and basic inline filtration. However, extractors still faced a major obstacle: consistency. Depending on the quality, age, or storage conditions of the raw biomass, extracts could still emerge with a dark, unappealing amber or green hue, heavily impacting market value.

The market demanded a solution that could refine lower-grade or older biomass into light, translucent, premium-shelf oil.

2019–2022: The CRC Revolution and the Channeling Dilemma

Enter Color Remediation Column (CRC) technology. By packing filtration columns with a selective array of adsorbent media—such as Bentonite clay, Silica gel, Activated Carbon, and Diatomaceous Earth—extractors unlocked the power of molecular chromatography.

CRC allowed labs to actively target and strip away:

• Chlorophyll and Carotenoids: The pigments responsible for dark green and black colors.

• Pesticides and Heavy Metals: Remediating contaminated batches into ultra-pure, compliant consumer goods.

• Lipids and Water: Ensuring a stable, clean-burning end product.

While CRC revolutionized the aesthetics and purity of 710 products, it introduced a massive operational bottleneck in the lab: the nightmare of hand-packing loose media.

The Danger of Manual Packs

For years, lab technicians manually poured loose, powdery media into steel columns over basic paper filter discs or stainless steel screens. This created two major vulnerabilities:

1. Media Migration: Microscopic, respirable dust and media particles escaping past the screens into the final consumer product, or into the laboratory air.

2. Fluid Channeling: Pressurized solvent finding the path of least resistance through loosely packed powder. Instead of filtering evenly through the media, the solvent tore a channel straight through it, leading to zero remediation, clogged screens, and ruined batches.

2023–Present: The Era of Absolute Filtration

The modern era of 710 is defined by pharmaceutical-grade execution. Extractors are no longer just trying to make clean oil; they are optimizing for efficiency, maximum throughput, and absolute safety.

This is where the engineering behind AFS Filters changed the trajectory of commercial color remediation.

By engineering the industry's first pre-packaged, mechanically compressed disposable CRC filter cartridges, the operational hazards of the old days were eliminated.

A molded, flawless sidewall seal stops fluid channeling entirely. Simultaneously, integrated 2.5-micron filter papers prevent media migration, ensuring that the hyper-pure concentrates celebrated every July 10th are as safe to consume as they are visually flawless.

A Look at Modern Remediation Blends

Today’s extraction technicians choose precise filter profiles tailored directly to the condition of their source biomass:

The Lesson of 710 History: Purity is not an accident; it is the result of deliberate, precise filtration engineering. From coffee filters to pre-compressed molecular cartridges, the evolution of OIL is a testament to an industry that refuses to stop refining.
