Here is a factual overview of Buffalo Extraction Systems' CO2 extraction offerings, based strictly on their documented information:

Overview

Buffalo Extraction Systems manufactures Supercritical Fluid CO2 Extraction (SCFE) systems used to isolate high-value organic compounds — such as cannabinoids, terpenes, essential oils, and other bio-actives — from plant material. The systems use food-grade carbon dioxide as the solvent, operated above its critical pressure and temperature so it behaves as a supercritical fluid capable of selectively dissolving target compounds.

Product Range

Buffalo offers SCFE systems across three tiers, designed for different stages of production:

• Level 1 (Lab / Pilot Scale) — Aimed at R&D labs, small-scale producers, and pilot extraction work. Fully automated and cGMP-compliant, intended for testing, validation, and recipe development. Their lab-level system operates at 350–650 bar (5,000–9,500 PSI) with a CO2 pump flow rate of 40–80 liters per hour.
• Level 2 (25 L / 50 L) — Mid-scale automated systems capable of both sub-critical and supercritical operation, suitable for boutique commercial production.
• Level 3 (Production Scale) — Larger, robust systems built for commercial throughput, emphasizing speed and consistency in high-volume operations.

How the System Works

The process begins by pressurizing and heating CO2 gas — using a high-pressure pump and heater — until it reaches the supercritical state. Milled raw material is loaded into one or more extractors, where supercritical CO2 flows through and dissolves the target compounds. The extract-laden CO2 then passes through pressure-regulator valves into a series of separators (typically two), each held at a different pressure to fractionate the extract into different components. The CO2 is then recovered and recycled within the system.

Key Engineering Features (as stated by Buffalo)

• Precise pressure control for targeted, selective extraction
• Consistent pump flow control to maintain extraction efficiency
• Fractional separation across multiple separator stages
• Sealing technology designed to reduce maintenance and downtime
• An extractor closure design intended for faster batch changeovers
• Integrated automation and recipe optimization based on harvest variability
• EU GMP / cGMP-compliant builds

Applications

The systems are used in cannabis and hemp (THC and CBD crude oil), as well as broader botanical applications including essential oils, spices, herbs, pharmaceuticals, cosmetics, and food ingredients.

Note on pricing and exact specifications: Buffalo does not publish complete spec sheets or fixed pricing publicly — quoted figures vary by configuration and they handle these through direct quotes. So if you need exact throughput numbers, extractor volumes for Level 3, or pricing, those would need to come from the company directly rather than from any summary.
