Tilt-to-Empty Feature

Emptying large high pressure reactors typically requires a bottom drain valve, which in some applications is undesirable. For researchers working with abrasive slurries, biomass particles or other materials incompatible with bottom drain valves Parr has developed a "Tilt-to-Empty" feature.

Parr Introduces New A2000G High Pressure Electrolyzer Cell

For electrochemical research involving carbon dioxide and water reduction.

A2000G Electrolyzer Assembly
A2000G Electrolyzer Assembly

Over the past decade, increasing interest has been directed towards utilizing carbon dioxide in generating liquid fuels and chemicals as a means to a sustainable, carbon-neutral based economy. The production of either carbon monoxide (CO) or synthesis gas (syngas), a combination of CO and H2, electrochemically from CO2 and H2O is an attractive option combining sustainable energy utilization and carbon recycling.

The new Parr A2000G High Pressure Electrolyzer Cell provides a unique and reliable hardware platform with many options for facilitating research in this area. The electrolyzer cell has a maximum working pressure of 10 MPa (1450 psi) at 200 °C. It is designed for quick assembly and reassembly. The flow-thru electrolyzer cell adopts a unique circular planar design for the titanium cathode flow field and the corresponding 316 Stainless Steel anode flow field. Other materials of construction are available.

Parr Introduces New 50 & 100 L Stirred Reactors

50 L Stirred Reactor System

Series 8500 Floor Stand Stirred Reactors

Parr Instrument Company is excited to announce a new series of large capacity, high pressure stirred reactors. The 50 L and 100 L models of the new 8500 Series expand the available volume of our standard offering by more than five times, while retaining the easy-to-use features our customers have come to expect from Parr.

Ideally suited for scale up or pilot work, the geometry, features, and operation are very similar to that of smaller Parr reactors, but with a volume intermediate between lab-scale and traditional production scale stirred reactors.

Tubular Reactor with 360° Rotation

When an unusually long or heavy tubular reactor is needed, the logistics of removing the reactor from the stand for cleaning or loading and removing catalyst or other internal packing can be daunting. Parr has designed a mechanism integrated into a custom tubular reactor stand which not only secures the reactor and furnace during operation, but makes easy work of accessing and manipulating large tubular reactors.

The furnace is hinged such that it easily swings out of the way. Once clear of the furnace the tubular reactor support slides out to an extended position for easier access. The tubular reactor is then easily rotated and locked securely into a upright, horizontal or inverted position. This allows easy access to the inside of the reactor for cleaning, inspection, loading of catalyst or other internals, and gravity-assisted discharge of the same.

What is Hydrothermal Synthesis?

Vessels with PTFE liners

Hydrothermal synthesis is a technique that involves the growth of materials from aqueous solutions at elevated temperature and pressure. The term hydrothermal usually refers to any heterogeneous reaction in the presence of aqueous solvents and complexing agents under high pressure and temperature conditions to dissolve and recrystallize materials that are relatively insoluble under ordinary conditions. The hydrothermal technique is widely used for the synthesis of a variety of inorganic compounds, nanomaterials and zeolites. It is a highly interdisciplinary subject and the technique is popularly used by geologists, biologists, physicists, chemists, ceramists, hydrometallurgists, material scientists, engineers, and many others.

In addition to their normal uses for sample digestion and dissolution, Parr’s Acid Digestion Vessels haven proven to be an excellent means to perform hydrothermal synthesis. Learn more.

Parr Multi Reactor Systems

Six Reactor Parallel System with Automated Sampling System
Six Reactor Parallel System with Automated Sampling System

Parr has seen a recent increase in demand for both parallel and series multi reactor systems. Parallel systems have been requested for use in high-throughput screening, combinatorial chemistry, corrosion testing, and catalyst testing. Multiple reactors plumbed in series have typically been configured as CSTR’s used for conducting multiple reactions sequentially. With this demand, we have designed and manufactured multi reactor systems using our largest stirred reactors (four 20L), to our smallest (six 25mL), and many in between.

Our multi reactor systems are used by combinatorial chemists at pharmaceutical companies, catalyst development researchers at petroleum companies, material scientists at polymer producers, production engineers at energy storage and mining companies, and academic researchers pursuing widely varied research avenues.

The Shift from Batch to Continuous-Flow Reactors

Recently, continuous-flow reactors have become commonplace in pharmaceutical laboratories and production facilities. This style of reactor permits easier automation of sequential and parametric changes in temperature, pressure, flow rate, and residence time. The amount of product becomes a function of time, not larger equipment, thereby leading to increased safety as smaller amounts of materials are present at any given time.
