Parr Instruments 300 mL Hastelloy C Pressure Reactor

The Parr Model 4561 300 mL Hastelloy C Pressure Reactor is built for researchers who demand strength, safety, and uncompromising corrosion resistance in high-pressure environments. Crafted from Hastelloy C alloy, this compact vessel is engineered to perform where stainless steel cannot, making it ideal for challenging chemical reactions involving aggressive acids, halogens, or other harsh reagents. Its rugged construction ensures long-term durability under extreme conditions, while its design supports precise, reproducible control for advanced laboratory synthesis and pilot-scale studies.

At HiTechTrader, we provide the Parr 300 mL Hastelloy C Pressure Reactor as a high-value refurbished solution for laboratories pushing the limits of chemical research. This Model 4561 Parr reactor is purpose-built for hydrogenation, polymerization, hydrothermal work, and supercritical fluid studies, withstanding pressures up to 3,000 psig and temperatures up to 350 °C. The integrated magnetic drive stirring system ensures reliable mixing without risk of leakage, while digital control options allow researchers to fine-tune pressure, temperature, and stirring speed in real time. Whether you're scaling up experimental chemistry or working with highly corrosive media, this system delivers durability, flexibility, and trusted safety at a fraction of the cost of new equipment.
