For heating a 500ml volume in China, the most common products available fall into two categories: laboratory heating mantles for precise scientific use and thermal/electric flasks for personal or travel use.

Heating Mantle 500ML in 220 Volt Suitable for laboratories, chemicals, pharmaceuticals, Dyes, Glass plants, etc. Particularly useful for Heating inflammable liquids. Electric heating net is hand knitted from glass Yarn and there is no joint to maintain the strength of the yarn and stands high temperature up to 350-degree c. the body of the mantle is spun one piece from non-rusting Aluminum (up to 500 ML Capacity) duly stoving painted. All heating mantles are lagged with special grade mineral wool. Heating Mantle with Energy Regulator Use Original mantle wire Indicator Light Inbuilt Easy to replace Mantle.

• Heating Technology: Uses an electric heating net hand-knitted from glass yarn to maintain high temperatures up to 350°C – 380°C.
• Structure: The outer body is typically a single-piece spun non-rusting aluminum shell.
• Power & Voltage: Most standard 500ml units operate at 200 to 250 Watts and are compatible with 220V – 240V power supplies.
