BK-1A Oxygen Bomb Calorimeter Medical Device

Both models share the same core performance (heat capacity range, resolution, accuracy, pressure endurance, power). The BK-1A has an LED display and does not include a built-in printer; the BK-1A+ has an LCD display and includes a printer.

Heat capacity is specified as 14400–14500 J/K for BK-1A and 14000–15000 J/K for BK-1A+. This is the calorimeter’s overall heat capacity used to convert measured temperature rise into energy released by the sample.

Resolution is 0.001 K (temperature change resolution). Measurement accuracy is stated as ≤60 J/g. Repeatability error is ≤0.2% (Grade C).

The bomb's pressure endurance is rated at 20 MPa. Never exceed this pressure and follow safe oxygen charging procedures and applicable lab safety rules.

Power consumption is ≤150 W. The required power supply is 220 V, 50 Hz.

Yes — the BK-1A+ includes a built-in printer. The BK-1A model does not include a printer.

Packing sizes listed are 760 × 600 × 570 mm (gross weight 45 kg) and 490 × 410 × 300 mm (gross weight 15 kg). Typically the larger box contains the main instrument and the smaller box contains accessories and consumables; exact packing detail may vary.

Typical consumables include high-purity oxygen, ignition wire or fuse, sample crucibles, and calibration standards (e.g., benzoic acid). Additional accessories may include tools for bomb sealing and a gas charging adapter.

Calibration is normally performed with a certified standard (commonly benzoic acid) to determine the system heat capacity. Follow the manufacturer's calibration procedure or contact the supplier for calibration services and traceable standards.

Use only trained personnel; inspect the bomb and seals before each run; never exceed rated pressure (20 MPa); charge oxygen in controlled manner; wear appropriate PPE; follow local regulations for high-pressure oxygen and explosive-risk testing. Keep the device in a well-ventilated, non-flammable area.

Regularly clean the bomb and vessel, inspect and replace seals and O-rings as needed, perform periodic pressure/leak tests, keep electrical connections dry and dust-free, and follow the manufacturer's recommended service intervals.

The product name includes 'Medical Device', but suitability for specific medical or clinical testing depends on local regulations and intended use. Consult the manufacturer and local regulatory guidance before using for medical diagnostics.

Installation and training policies vary by supplier. Contact the manufacturer or authorized distributor to arrange on-site installation, operator training, and commissioning if available.

Compliance with specific standards is not listed in the provided specification. Contact the manufacturer or supplier to obtain documentation about conformity to ASTM, ISO, or other applicable standards and for certificates if required.

Contact the manufacturer or authorized distributor for spare parts, consumables, and technical support. Provide the model number (BK-1A or BK-1A+) and a description of the issue to expedite assistance.
