In the journey from “Concept to Commerce,” the most critical phase is the pilot-scale validation. For production managers, the primary objective of a pilot plant is risk mitigation—financial, technical, and operational. Western States’ WSB-MicroPro is engineered to be more than a small-scale centrifuge; it is a data-generation engine designed to provide a repeatable roadmap for full-scale industrial success.
The Strategic Imperative of Pilot-Scale Extraction
Scaling an extraction process is rarely linear. Engineering complexities like mass transfer dynamics and thermodynamic phase equilibrium manifest differently as volumes increase. If you start with a “laundry-style” or consumer-grade machine at the R&D stage, your data will not translate to industrial equipment, leading to catastrophic failures during full-scale deployment.
The WSB-MicroPro solves this by providing the exact same physics at 4 liters that you will find at 40 pounds. By utilizing the MicroPro for R&D and process development, companies can “lock in” their validated SOPs (Standard Operating Procedures) in a controlled environment.

Technical Snapshot: The WSB-MicroPro
| Feature | Specification | Operational Benefit |
| Separation Force | 900 Gravities (Gs) | Overcomes capillary forces for 97%+ solvent recovery. |
| Volumetric Capacity | 4 Liters (252 in³) | Perfect for small-batch validation and R&D. |
| Temperature Range | Ambient to −40°C | Essential for terpene preservation and cryogenic extraction. |
| Safety Rating | Class 1 Div 2 (C1D2) | Meets strict fire codes for flammable solvent use. |
| Surface Finish | 32 Ra Finish | Sanitary 304L SS prevents contamination and ensures cGMP compliance. |
Detailed Analysis: Engineering for Seamless Scalability
The true value of the WSB-MicroPro lies in its identical engineering architecture. In production management, the greatest enemy is variance. Western States addresses this by ensuring that the MicroPro, the WSB-15, and the WSB-40 all share the same technical pillars.
1. The Physics of Recovery
The MicroPro delivers 900 Gs of force, identical to the production-scale models. This means the solvent recovery rates and biomass dryness levels you achieve in the lab—often reaching 97% or higher—will be the exact same rates you see when you scale to a WSB-40 industrial unit.
2. cGMP Readiness from Day One
Certification is built, not bought. By using the MicroPro, R&D teams work with pharmaceutical-grade 304L stainless steel and 32 Ra finishes from the start. This ensures that when the time comes for a GMP audit, the materials of construction and sanitary design are already validated and consistent across the entire production history.
3. Integrated Control Systems
Western States utilizes Allen-Bradley PLC and Panelview HMI controls across the entire WSB line. A recipe developed on the MicroPro’s C1D2 touchscreen can be seamlessly transferred to larger units, ensuring that agitation cycles, spin-dry times, and temperature parameters remain constant as you grow.
Strategy: The Path to Industrial Leadership
For operations looking to dominate the market by 2026, the strategy is simple: Start small, validate perfectly, and scale seamlessly.
- Validate on the WSB-MicroPro: Use the compact footprint (24-3/8” length) to refine your extract profiles, especially heat-sensitive compounds like terpenes, using cryogenic stability down to -40°C.
- Mitigate CapEx Risk: Renting or investing in a MicroPro allows organizations to assess performance and suitability before committing to large-scale infrastructure.
- Bridge to Production: Once the process is “locked-in,” move to the WSB-15 (15 lbs capacity) for boutique production or the WSB-40 (40 lbs capacity) for high-throughput industrial processing.

Frequently Asked Questions (FAQ)
Can I use the WSB-MicroPro for small-scale commercial production?
Yes. While designed for R&D and pilot batches, its robust 304L stainless steel construction and C1D2 rating make it suitable for niche, high-value small-scale production.
Is the data gathered on a MicroPro applicable to larger Western States models?
Absolutely. Because the WSB-MicroPro shares the same 900 G-force and cryogenic temperature capabilities as the WSB-15 and WSB-40, the solvent recovery and yield data you gather is directly scalable.
Does the MicroPro require specialized facility utilities?
The WSB-MicroPro is designed for ease of use in lab environments, requiring standard 120VAC power input. It can be integrated with existing lab chillers to maintain temperatures as low as -40°C.
How does the MicroPro assist with GMP certification?
It provides the “Legendary Dependability” and sanitary design required for regulatory compliance. By using the same materials and data integrity (21 CFR Part 11 ready controls) as production units, it simplifies the 3Q validation (IQ/OQ/PQ) process.
Why is 900 Gs important for a pilot-scale unit?
Lower-force centrifuges cannot overcome the capillary pressure that traps ethanol in biomass. By providing 900 Gs, the MicroPro ensures that your pilot batches reflect true industrial solvent recovery efficiency, rather than over-estimating losses.
Conclusion: Legendary Dependability at Every Scale
Western States Machine Company has been pioneering centrifugation since 1917, with machines from the 1950s still in service today. The WSB-MicroPro carries this legacy of “Legendary Dependability” into the lab.
For production managers, the MicroPro is not just a purchase; it is a partnership in performance. It allows you to de-risk your investment, validate your process, and provide a clear, technical path toward becoming a leader in the industrial extraction of botanical compounds.
