The Parr 6420 Automatic Isoperibol Calorimeter Expanded System is designed for high-precision calorimetric testing with advanced automation and ease of use. Featuring a fixed bomb and bucket design, this system reduces operator intervention while maintaining exceptional test repeatability and durability.
Product Features
- Parr Fixed Bomb and Bucket Technology: Bomb and bucket remain fixed during routine operation, enhancing automation and reducing operator time by about five minutes per test compared to removable bomb systems.
- Oxygen Charging and Release: Oxygen supply directed into the bomb head with dynamic sealing check valve; automatic gas release at test completion.
- Fixed Bucket: Designed for smooth and volumetric filling, with automatic draining and cooling after combustion to rapidly restore starting temperature.
- Fixed Bomb: Patented closure design with simple one-sixteenth turn lock; O-ring seal optimized for minimal wear, extending bomb life.
- Automatic Bomb Washing: Removes combustion residues shortly after testing, improving service life and eliminating tedious manual cleaning.
- 1138 Oxygen Combustion Bomb: Alloy 20 construction resists mixed nitric and sulfuric acids; redesigned for enhanced durability and fast sample loading with Quick Twist-Lock closure.
- Alternative 1138CL Bomb: Made from halogen-resistant Hastelloy G30 for corrosive chlorine-containing samples.
- Bomb Specifications: 250ml volume, rated for 2000 psi working pressure, hydrostatically tested to 3000 psi, sample range approx. 1g or 5000-8000 calories.
- Straight Wall Design: Improves rinse recovery, precision, test times, and enables vessel re-boring for longer service life.
- A1450DD Spare Head: Optional for high throughput, allowing sample preparation during testing.
- Control Chart Capabilities: Instant plotting and viewing of standard results with user-defined warning and control limits for process control.
- Laboratory Requirements: Requires 99.5% oxygen, nitrogen or house air at 80 psi, and deionised water supply.
