The Parr 5513 Reactor is a compact, high-performance pressure vessel engineered for demanding chemical reactions under extreme conditions. Designed for lab and pilot applications, this 100 mL reactor offers precision, safety, and flexibility for research in catalysis, high-pressure synthesis, and advanced materials development.
Compact High-Pressure Design
As part of Parr’s Series 5500 High-Pressure Compact Reactors, the 5513 model supports up to 3,000 psi (≈ 207 bar) and tolerates high temperatures (depending on seal choice) — ideal for aggressive chemical environments.
Stainless Steel Construction
Wetted parts are built from T316 stainless steel, delivering excellent corrosion resistance, durability, and long-term reliability even with harsh reagents.
Flexible Sealing Options
Compatible with PTFE flat gaskets (up to ~350 °C), as well as FFKM or FKM O-rings (for lower temperature limits), allowing adaptation to different process needs.
Stirring & Mixing Capability
Equipped with a magnetically-coupled stirrer, this reactor supports mixing in viscous media.
Control & Instrumentation
Standard features include gas inlet/outlet valves, a sampling valve, pressure gauge, safety rupture disc, and internal thermocouple.
Many units are paired with a Parr 4848 PID controller, allowing ramp/soak programming and precise temperature control.
Bench-Top Format
The reactor is a moveable-head, compact bench unit, minimizing footprint while maintaining high performance.
