• 【About Dimensions】Diameter of the base - 7.9 cm / 3.07 inches, height - 14.5 cm / 5.98 inches. Weight is approximately 224 grams.
• 【Connection】When a burner is required, connect the air inlet to the gas storage tank with a gas hose with an inner diameter of 8-9 mm (5/16" or 3/8").
• 【High Temperature Resistant Alloy】Bunsen burners are usually used to heat non-flammable objects or solutions at temperatures higher than those of alcohol lamps. Therefore, we use high temperature resistant brass alloy metal, which makes it and does not change colour.
• 【Safe and Efficient When Burning】 The Bunsen burner is equipped with a gas regulator, air regulator and flame stabiliser, so that the air and combustible gas fuel are fully mixed, and the flame will not flow back into the gas supply pipe when burning, thus providing a stable, safe and efficient heat source.
• 【Wide Application】This Bunsen burner provides a stable and powerful heat source, which can be used in laboratories, clinics, outdoor cooking, camping, barbecues, jewellery appraisal and other jobs that require heating and disinfection.
