Key Features
- Each batch of material used for Advance Calorimeter Bomb is put through a series of physical and chemical tests to verify the prescribed standards for fabrication of a high pressure vessel. This ensures the highest standards of customer safety.
- The Bomb Body and Lid are machined from corrosion resistant Stainless Steel namely Austenitic Steel satisfying the special ringing and bend tests for inter-crystalline corrosion and having good high temperature properties. The interior of the Bomb has been maintained cylindrical throughout its length. The metal seal between the body and the lid is backed by a sealing ring. The Closure Ring is made of Aluminium Bronze or Stainless Steel and hand tightening of the Closure Ring is sufficient to ensure perfect gas tight sealing at a pressure of 300 kg/cm2.
- The user has a choice of either the standard Schrader Valve based Combustion Bomb or our latest design of Schrader Valve less Combustion Bomb design. This is additionally provided with a Automatic Gas Filling Adaptor which simplifies the Oxygen filling procedure. The valve opens and allows filling of Bomb with Oxygen because of Oxygen pressure for cylinder. It closes when pressure from Oxygen Cylinder is cut off./font>
- Extremely Easy to use Push Fit Type Gas Filling System for fast and accurate filling of Oxygen
- Each Combustion Bomb is individually tested at a pressure of 300 kg/cm2 for a period of 10 minutes for signs of any leakage as per IP guidelines
- Calorimeter Jacket and Water Jacket fabricated from Chromium plated Copper as per International specifications
- The introduction of a Safety Relief Valve in the Gas Filling Adaptor ensures additional user safety from accidental Oxygen overfill.
- New Soft Control Fine Regulating Valve with built-in pressure gauge ensures fatigue free operation of the system
- Latest Design Compact Stirrer to minimize external heating effect
- The new High Accuracy Digital Temperature Indicator with built-in printer has an additional stabilizing circuit which ensuring that readings have high accuracy and repeatability
- High Mechanical standards and easy controls
- The instrument is Accurate, Reliable and User Friendly.

FAQs of Isothermal Bomb Caloriemeter BCM-D:
Q: How does the automatic oxygen filling system enhance safety and ease-of-use in the BCM-D calorimeter?
A: The BCM-D features an oilless automatic oxygen filling unit, which allows for safe and precise oxygen charging up to 30 bar without manual intervention. This reduces operator risk and streamlines the setup process for each test.
Q: What types of samples can be analyzed using the Isothermal Bomb Calorimeter BCM-D?
A: The BCM-D can be used to determine the calorific value of both solid and liquid fuel specimens. It is optimized for sample sizes between 0.5 and 1.0 grams, making it suitable for standard laboratory fuel testing.
Q: When should calibration and maintenance be performed on the BCM-D calorimeter?
A: Calibration should be performed regularly using the supplied certified calibration weights to ensure accuracy. Routine maintenance, including checking the pressure interlock and cooling system, is recommended based on the manufacturers schedule or after frequent use.
Q: Where is the BCM-D ideal for installation and operation?
A: The calorimeter is designed for benchtop mounting in laboratory environments. Its compact dimensions (550 mm x 350 mm x 500 mm) and robust construction make it suitable for research facilities, educational institutions, and quality control labs throughout India.
Q: What is the process for conducting a calorific value test with the BCM-D calorimeter?
A: To perform a test, users weigh the sample, place it in the nickel crucible, and install it within the stainless-steel bomb. After sealing, the system automatically charges oxygen, initiates ignition, and records the calorific value, with measurements displayed instantly. All test data can be saved internally or exported via USB.
Q: How does the built-in cooling jacket and high-speed stirrer affect results?
A: The built-in water cooling jacket and high-speed PTFE-coated stirrer ensure uniform temperature distribution and prevent thermal losses, resulting in fast, reliable, and highly repeatable calorific measurements for each specimen.
