The Across International SR200 Stainless Steel Reactor is a large-capacity processing reactor designed for pharmaceutical production, chemical synthesis, cannabis extraction processing, food-grade processing, and pilot-scale manufacturing environments.

Built with pharmaceutical-grade 316L stainless steel wetted components and an electropolished internal chamber, the SR200 provides exceptional corrosion resistance, sanitary operation, and superior vacuum performance.

This reactor system features a dual-jacket temperature control system, shell-and-tube condenser with 70 tubes, and a heavy-duty stainless steel frame with integrated stirring motor controller, making it ideal for large-scale laboratory and industrial applications.

Peer-reviewed configurations are available for C1D1 hazardous environments when equipped with the pneumatic motor system.

Key Features

Pharmaceutical-Grade 316L Stainless Steel Construction

All wetted components of the main vessel and lid are constructed from 316L stainless steel, the industry standard for sanitary processing.

Benefits include:

• Excellent corrosion resistance
• Food and pharmaceutical compatibility
• Long equipment lifespan
• Easy sterilization and cleaning

Structural components are manufactured from 304 stainless steel.

---

Electropolished Internal Chamber

The reactor chamber features an electropolished interior surface.

Electropolishing:

• Reduces surface roughness
• Levels microscopic peaks and valleys
• Improves vacuum performance
• Reduces out-gassing rates
• Improves pumping speed
• Reduces friction and wear
• Creates a semiconductor-grade sanitary surface

This finish is essential for pharmaceutical and food processing applications.

Dual Jacket Temperature Control

The SR200 reactor includes a dual jacket system with sealed outer insulation jacket.

Benefits include:

• Superior thermal efficiency
• Improved temperature control inside the chamber
• Reduced energy loss
• Consistent reaction performance

---

High-Efficiency Shell & Tube Condenser

The reactor features a shell-and-tube condenser with 70 tubes, providing excellent vapor condensation performance.

Specifications:

• Condensing surface area: 0.89 m²
• Top-mounted vacuum port for improved vapor flow
• Flexible bellow connection reduces shipping damage

---

Dual Collection Tank System

The reactor includes dual collection tanks with large sight glasses, allowing operators to drain solvent without breaking vacuum.

Collection Tank Options

• Option 1: 10L × 2 stainless steel tanks with manifold
• Option 2: 50L tank with mobile dolly
• Option 3: 100L tank with mobile dolly
