From Biomass to Bottle
Solving Your Toughest Extraction Challenges
Preserve Terpenes & Maximize Potency with Cryogenic Temperature Control
The most valuable extracts and terpenes are also the most volatile. Standard extraction temperatures can degrade these compounds, reducing the quality and market value of your final product. Our botanical centrifuges are engineered for precise and stable low-temperature ethanol extraction, operating at temperatures down to -40°C and below. This cryogenic capability minimizes the co-extraction of undesirable compounds like waxes and chlorophyll while preserving the full, rich profile of your source material, leading to a purer, more potent extract that requires less post-processing.
Drive Down Cost-Per-Gram with Superior Solvent Recovery
Solvent loss is a direct hit to your bottom line. Inefficient separation leaves valuable ethanol trapped in the spent biomass. Western States centrifuges utilize high G-forces and optimized cycle parameters to achieve industry-leading solvent recovery rates of up to 97% or more. This translates to less solvent waste, higher extracts yield, and a significantly lower operating cost, maximizing the profitability of every batch.
Your Pathway to GMP Compliance and Safe Operation
As the market matures, regulatory compliance is non-negotiable. Our centrifuges are designed with cGMP principles in mind, featuring sanitary tri-clamp connections, food-grade construction materials (SS304/SS316L), and clean-in-place (CIP) capabilities. For operations using volatile solvents like ethanol, safety is paramount. Our systems are equipped with fully integrated Class 1, Division 2 (C1D2) explosion-proof motors and controls, ensuring your facility meets the highest safety standards.
Seamless Scalability: From Pilot R&D to Full-Scale Production
