Pressure Sterilizer/Autoclave (Non Electronic)

A pressure sterilizer, also known as an autoclave, is a device that sterilizes equipment and instruments by subjecting them to high-pressure saturated steam at a temperature of 121°C (250°F). It kills all microorganisms, including bacteria, viruses, and spores. The objects to be sterilized are loaded into a sealed chamber and held at the required conditions for a set period of time. Afterward, the pressure is gradually released, and the sterilized objects can be removed. Pressure sterilizers are commonly used in medical, dental, and laboratory settings to prevent infections and ensure accuracy of test results.

Water Trap (10ml)

A water trap is a device that removes moisture from gas or air streams to prevent equipment damage or product quality issues. It uses filters, desiccants, or condensers to trap moisture, which is collected in a reservoir and drained periodically. Water traps are used in various applications, including gas chromatography and air conditioning systems. Proper maintenance and cleaning are important for effective and efficient operation.


Petroleum spirit is a colorless or slightly yellowish liquid fuel derived from petroleum, composed of hydrocarbons with a boiling point range between 30°C and 205°C, with a density of 0.71-0.78 g/cm3 and a flash point of -40°C to -60°C. It is used as a fuel for internal combustion engines and as a solvent for various applications, but it also poses significant health and environmental risks. Its octane rating determines its ability to resist knocking in an engine and ranges from 87 to 93 in the United States.

Andon BP Machine

Andon Bp Machine monitors have a measurement range of 0-299 mmHg for systolic pressure and 40-199 mmHg for diastolic pressure with an accuracy of +/- 3 mmHg. The cuff size can vary, but most come with a standard-sized cuff that fits arm circumferences of 22-32 cm. Andon blood pressure monitors typically have a large, easy-to-read digital display and can be powered by batteries or an AC adapter. Memory functions are also common, allowing for the storage of multiple readings to track blood pressure over time. Additional features, such as irregular heartbeat detection and date/time display, may also be included depending on the model.
