Designed for High-Temperature Acid Digestion

Acid digestion is an essential step in many analytical chemistry workflows where solid samples must be dissolved before elemental analysis. The Parr 4748 digestion reactor provides a sealed, high-pressure environment that allows acids to operate at elevated temperatures and pressures, enabling the complete breakdown of challenging materials such as:

• Mineral ores and geological materials

• Catalyst samples

• Polymers and plastics

• Environmental samples

• Industrial materials

By operating under pressure, the digestion reactor allows acids to reach higher effective temperatures than open-vessel digestion methods, significantly improving digestion efficiency and recovery rates.

Reliable Sample Preparation for Analytical Laboratories

Accurate elemental analysis depends heavily on consistent and contamination-free sample preparation. The Parr 4748 reactor helps laboratories achieve reliable digestion results by providing uniform heating conditions, tight sealing to prevent sample loss, and repeatable digestion conditions across experiments.

These features are particularly important for laboratories performing trace metal analysis using methods such as ICP-MS, ICP-OES, and Atomic Absorption Spectroscopy, where extremely low detection limits require careful sample handling.

Robust Construction for Demanding Laboratory Use

The Parr 4748 digestion reactor is designed for long-term reliability in routine laboratory workflows. Fabricated from T-304 stainless steel, the reactor body offers excellent corrosion resistance for common digestion reagents. When paired with a chemically resistant liner system, this construction helps maintain consistent performance during repeated digestion cycles.

Engineered to safely operate under demanding digestion conditions, the operating limits include:

• Maximum Pressure: 1900 psi

• Maximum Temperature: 250 °C

These capabilities allow laboratories to digest samples that may be difficult or impossible to process using traditional open digestion methods.

Secure Six-Screw Closure System & Easy Operation

The reactor uses a six cap-screw closure system designed to provide reliable, uniform compression across the reactor seal. This mechanical design ensures secure containment of digestion reagents during high-temperature operation and leak-tight performance during repeated heating cycles.

Additionally, the compact footprint is suitable for standard laboratory heating blocks or ovens, featuring easy sample loading, straightforward cleaning, and seamless integration into routine QA/QC workflows and regulatory testing procedures.

Frequently Asked Questions (FAQ)

What is the Parr 4748 Acid Digestion Reactor used for? The Parr 4748 is used to safely dissolve difficult solid samples in strong acids under high temperature and pressure. This breaks the sample down into a liquid solution so it can be accurately analyzed for trace metals using ICP, ICP-MS, or AA spectroscopy.

What are the pressure and temperature limits of the Parr 4748? Constructed from T-304 stainless steel, the Parr 4748 reactor body is rated to safely contain operating pressures up to 1900 psi and withstand maximum temperatures up to 250 °C.

Why use a Six Cap-Screw closure on a digestion vessel? The six cap-screw closure provides a highly secure, mechanical seal. By tightening six independent bolts, the operator ensures uniform compression across the vessel's sealing surfaces, which is critical for preventing leaks of dangerous, high-pressure acid vapors during the digestion process.
