ROSITEK Gravitas 8-Ton Hydraulic Rosin Press - Landscape 3x7" Dual Heat Machine for Pure Faint Amber Extracts

The Gravitas 8 Advantage: Elite Power in a High-Stiffness Frame

The Gravitas 8 (formerly REP8) is designed for the extractor who bridges the gap between personal craft and commercial production. Built with a premium All-Aluminum 6061 Frame, it offers a superior stiffness-to-weight ratio, allowing it to withstand over 10 tons of force with zero structural fatigue. The massive 3x7" landscape plates provide the "territory" needed for high-volume throughput while maintaining professional purity.

Product Highlights & Core Features

• High-Tensile 6061 Aluminum Build: Every frame component is CNC-machined from solid aluminum for elite rigidity, ensuring 100% of the 8-ton force is delivered to your material without frame flex.
• Landscape 3x7" Thermal Plates: The elongated surface area allows you to process up to 28g of flower or multiple bags simultaneously. The wider path means rosin escapes the heat zone faster.
• Industrial 8-Ton Vertical Jack: Driven by a heavy-duty, replaceable 8-ton bottle jack (peaking at 9 tons). This modular system ensures the power unit can be serviced independently for a lifetime of use.
• Precision Dual PID Control: Features two pluggable PID temperature controllers with stainless steel rod heaters. This laboratory-grade setup delivers synchronized heat with pinpoint accuracy.
• Multi-Bag Commercial Capacity: Specifically engineered to handle up to three 2x4" rosin bags at once, making it the ultimate choice for small-batch operators prioritizing efficiency.
• Advanced Thermal Barrier: Includes high-performance insulating layers to prevent heat transfer to the frame, significantly extending the life of hydraulic seals.

Expert Advice: Mastering the Gravitas 8 without a Gauge

Even without a hydraulic gauge, the Gravitas 8’s high-stiffness frame provides excellent Tactile Feedback to guide your extraction:

• Incremental "Sensory" Pumping: When the handle feels like it is pressing into a "firm sponge," saturation has begun. Pump only 1/4 stroke every 15 seconds to allow oil flow.
• Detecting the "Physical Stop": As extraction nears completion, the handle resistance will turn into a "hard wall." Stop immediately to preserve oil color.
• Landscape Triple-Bag Layout: Align three 2x4" filter bags side-by-side with a 0.5-inch gap to utilize the shortest exit path offered by the 7-inch wide plates.

Technical Specifications (Gravitas 8)

The "Zero-Blowout" Protocol

1. Material Prep: Use a 2x4" Pre-press Mold. Material should be at 62% RH for optimal pliability.
2. The Saturation Melt: Close plates snugly. Wait 60-90 Seconds to ensure large mass is fully liquefied before force.
3. Progressive Compression: Use slow 1/4 pumps. Allow oil to escape the 7-inch wide plates to prevent dark oxidation.
4. Plate Maintenance: Clean the 3x7" surface while warm with 99% ISO alcohol.
