Holland Green Science

Laboratory-Grade Precision for Commercial Extraction

Holland Green Science builds equipment for environments where consistency equals credibility. The Xiros Mikro lyophilizer maintains vacuum pressures below 0.1 mBar. The Hephaestus V-series ovens control temperatures within ±1°C. The Preseva freezers prevent temperature fluctuations that degrade trichome integrity. This precision eliminates the variables that cause batch-to-batch inconsistency in artisan operations, delivering repeatable results that scale from small-batch to commercial production.

Complete Laboratory Infrastructure for Solventless Processing

Holland Green Science offers integrated systems that address every critical control point in concentrate production. Each component functions independently but performs optimally when combined into a complete processing environment.

• Freeze-Drying Systems: The Xiros Mikro lyophilizer removes moisture from bubble hash through sublimation, converting ice directly to vapor without the liquid phase that degrades cannabinoids. Operating at sub-zero temperatures throughout 20-24 hour cycles, it preserves 90%+ of volatile monoterpenes compared to 60-70% retention with traditional air-drying. The automated vacuum and temperature controls eliminate manual monitoring while delivering pharmaceutical-grade consistency. Pair with bubble hash bags and washing equipment for complete solventless workflows.
• Ultra-Low Temperature Storage: The Preseva Pagoma and Preseva Plus freezers maintain stable -40°C to -80°C environments for storing fresh-frozen material before washing and preserving finished concentrates post-processing. Consistent cold temperatures prevent ice crystal formation that ruptures trichome heads during storage. The Preseva Plus offers larger capacity for commercial operations processing 50+ lbs weekly, while the Pagoma serves artisan extractors with tighter footprints.
• Vacuum Oven Technology: The Hephaestus V-series vacuum ovens (models V 094, V 213, V 900) purge residual moisture and solvents from concentrates under controlled negative pressure. This prevents oxidation during the curing process while accelerating evaporation rates. The V 094 handles small-batch artisan production, while the V 900 processes commercial volumes with multi-shelf configurations and programmable temperature ramping.
• Convection Drying Systems: The Hephaestus convection ovens (models 124, 222) provide precise airflow and temperature control for drying plant material, curing edibles, or heat-treating packaging materials. Unlike vacuum ovens that operate under negative pressure, these units circulate filtered air at atmospheric pressure for applications where gentle, even heating matters more than solvent removal.
• Vacuum Pump Infrastructure: Holland Green Science Premier and Anemos vacuum pumps power both lyophilizers and vacuum ovens with oil-free operation that prevents contamination. The Anemos series delivers higher flow rates for commercial freeze-dryers running continuous cycles, while Premier models serve smaller systems with quieter operation suitable for shared lab spaces.

Matching Equipment Capacity to Processing Volume

Holland Green Science designs equipment across multiple capacity tiers. Selecting appropriately sized systems prevents workflow bottlenecks while avoiding capital expenditure on oversized infrastructure.

• Artisan-Scale Labs (5-20 lbs/week): Small-batch extractors benefit from the compact footprint of the Xiros Mikro lyophilizer paired with the Preseva Pagoma freezer and Hephaestus V 094 vacuum oven. These systems operate on standard 110V power and fit within 10-15 square feet of lab space. This configuration handles weekend extraction runs without requiring dedicated facility infrastructure, making pharmaceutical-grade processing accessible to home-based artisans upgrading from traditional drying methods.
• Mid-Scale Production (20-50 lbs/week): Operations processing multiple strains simultaneously require larger freezer capacity (Preseva Plus) and mid-tier vacuum ovens (Hephaestus V 213) that accommodate multiple trays. At this scale, investing in dedicated vacuum pumps reduces maintenance frequency and extends equipment life compared to running consumer-grade components at maximum capacity.
• Commercial Facilities (50+ lbs/week): High-volume processors benefit from the Hephaestus V 900 vacuum oven's programmable temperature profiles and the Preseva Plus freezer's walk-in storage capacity. These systems reduce labor costs through automation while delivering the batch consistency necessary for white-label manufacturing and distributor contracts. Commercial operators often run multiple lyophilization cycles daily, making the Anemos vacuum pump series essential for maintaining processing schedules during peak harvest seasons.

Integrating Laboratory Equipment into Extraction Workflows

Proper equipment sequencing and operation maximizes product quality while extending system longevity. These practices optimize Holland Green Science equipment performance.

• Temperature Progression Protocol: Fresh-frozen material must reach -40°C in Preseva freezers for 12+ hours before washing to prevent trichome head rupture. After washing, immediately return separated hash to freezer storage before loading into the Xiros Mikro for lyophilization. This unbroken cold chain preserves monoterpenes that volatilize above -20°C.
• Vacuum System Maintenance: Oil-free Anemos and Premier pumps require less frequent servicing than oil-lubricated alternatives, but monthly inspection of intake filters prevents particulate contamination that reduces pumping speed. Replace pump seals annually in commercial operations running continuous cycles. A properly maintained system pulls vacuum below 0.1 mBar within 15 minutes.
• Cross-Contamination Prevention: Dedicate specific vacuum ovens to particular concentrate types (hash vs. rosin vs. distillate) to prevent terpene cross-contamination. The Hephaestus V-series stainless steel interiors clean easily with isopropyl alcohol between batches, but microscopic residues can affect aromatic profiles in sensitive full-melt products. Commercial labs often maintain separate ovens for different product lines.
• Environmental Controls: Holland Green Science equipment performs optimally in climate-controlled environments maintaining 65-75°F and 40-60% relative humidity. Excessive ambient humidity extends freeze-drying cycles, while temperature fluctuations force vacuum systems to work harder, increasing wear on compressor components. Installing equipment in dedicated HVAC-controlled rooms extends service life and reduces energy consumption.
