Prep Series

Description

The Prep J degasser is designed for efficient and controlled preparation of powder or particulate samples prior to surface-area and porosity analysis. With programmable temperature control, vacuum or flow modes, and multi-sample capability, the system ensures consistent degassing of multiple samples under stable and reproducible conditions.

Key Features

• Programmable furnace with a temperature range from ambient up to approximately 400 °C, offering ±1 °C control accuracy.

• Multi-port configuration (4-port or 8-port) for simultaneous degassing of multiple samples and higher laboratory throughput.

• Built-in vacuum system with a multi-stage pump and pressure monitoring to prevent loss of fine powders during evacuation.

• Flow-degasser variant available for inert-gas flow operation, ideal for vacuum-sensitive or delicate materials.

• Compact benchtop design with integrated sample holders and an intuitive user interface for easy method setup.

Typical Specifications

• Temperature range: Room temperature to ~400 °C

• Control accuracy: ±1 °C

• Degassing ports: Up to 8-sample capacity (depending on model)

• Ultimate vacuum: Around 10⁻² Pa (for vacuum models)

• Dimensions / Weight: Approximately 430 mm × 405 mm × 725 mm; ~36 kg for an 8-port vacuum unit

Applications

• Sample activation by removing moisture, volatiles, and adsorbed gases before BET surface-area or porosity measurement.

• Pretreatment of catalysts, adsorbents, and porous materials to ensure reproducible surface conditions.

• Laboratories requiring simultaneous degassing of multiple samples under controlled temperature, vacuum, or inert-gas flow.

• Academic, industrial, and QC laboratories seeking reliable and repeatable sample preparation.

Why Choose This System

• Ensures reproducible surface analysis results by standardizing the degassing process.

• Increases laboratory productivity with multi-sample operation.

• Offers flexibility between vacuum and flow modes for various material sensitivities.

• Compact, efficient, and easy to integrate into routine analytical workflows.

Considerations

• May require supporting infrastructure such as vacuum pumps, gas supply, and exhaust systems depending on configuration.

• Correct sample handling and ramp-rate control are essential for accurate results.

• Selecting the appropriate model (number of ports, temperature range, degassing mode) is crucial for efficiency.

• Operator training helps optimize methods for delicate or high surface-area materials.
