Laboratory Micro Oxygen Filling Instrument for Precision Bomb Calorimetry Charging

Product Overview

This micro oxygen filling instrument is a specialized benchtop gas-regulation system engineered for the safe, precise pressurization of laboratory oxygen bombs, combustion calorimeters, and micro-reaction vessels. Sourcing gas directly from industrial high-pressure oxygen cylinders rated up to 20 MPa, this instrument down-regulates and meters output pressure into stable, application-specific charging bands between 0.1 and 3.5 MPa. By integrating an ultra-fine metering needle valve, heavy-duty pressure-relief mechanics, and a non-sparking, oil-free fluid circuit, the equipment ensures consistent oxygen partial pressures while mitigating the severe risks inherent to handling compressed pure oxygen.

Designed primarily for testing protocols governed by ASTM, ISO, and DIN analytical standards, this system is an indispensable front-end interface for coal evaluation, petrochemistry, bio-mass calorific profiling, waste-to-energy characterization, and energetic materials testing. The controlled inlet geometry prevents the mechanical disturbance or aerosolization of volatile powders and loose pellet specimens inside the combustion crucible, preserving sample integrity prior to ignition. Routine commercial testing laboratories and dedicated academic institutions rely on the equipment to streamline sample preparation workflows while enforcing rigorous laboratory safety standards.

Built to withstand continuous, high-cycle operation in industrial laboratories, the unit is assembled from ultrasonically degreased oxygen-compatible brass and 316L stainless steel alloys. Each mechanical sub-assembly undergoes hydrostatic proof-testing, helium leak integrity assessment, and microscopic particulate inspections. Operators gain steady, repeatable pressure control, effortless bomb coupling, and complete confidence in long-term operational resilience under heavy daily testing schedules.

Key Features

• Certified Oil-Free and Oxygen-Cleaned Architecture: Completely degreased in compliance with stringent oxygen-handling protocols, eliminating all traces of hydrocarbons and particulate contaminants to neutralize ignition risks caused by adiabatic compression in high-pressure pure oxygen atmospheres.
• Fine-Pitch Soft-Start Needle Throttle: An engineered needle valve mechanism allows micro-metered, laminar gas admission, preventing sudden acoustic pressure shocks or turbulent gas waves that could scatter fine powdered samples out of analytical crucibles.
• Precision Dual-Scale Pressure Indication: Outfitted with an industrial Class 1.6 Bourdon-tube pressure gauge featuring clear dual graduations (0–6.0 MPa and psi/bar), empowering technicians to hit target combustion pressures within tight tolerances of ±0.05 MPa.
• Integrated Pop-Off Safety Relief Valve: A tamper-resistant, factory-calibrated spring-loaded relief valve automatically discharges gas if system pressure exceeds 3.5 MPa, proactively protecting downstream combustion bomb vessels from over-pressurization.
• Ergonomic Quick-Coupling Snap Socket: Features an industrial-grade quick-connect interface designed for single-handed engagement with standard calorimeter bomb filling nipples, guaranteeing gas-tight sealing without thread wear, galling, or manual wrenching.
• Independent Fast-Action Decompression Bleed: A dedicated manual exhaust valve permits immediate, controlled venting of residual line pressure between the regulator and the bomb valve after charging, allowing effortless and safe connector disconnection without recoil.
• Forged Non-Sparking Wetted Metallurgy: All primary fluid pathways are precision-machined from high-density forged brass and 316L stainless steel, conferring exceptional resistance to cyclic fatigue, stress-corrosion cracking, and galvanic oxidation.
• Weighted Anti-Topple Benchtop Platform: Engineered with an ultra-low center of gravity, a heavy ballast base plate, and vibration-dampening elastomer feet that hold the instrument completely stationary during single-handed valve operation.
