Heating Mantle 100W - 100ml

These economy heating mantles are ideal for distillation, evaporation, extraction and boiling of liquids in round bottom flasks. They feature electronic temperature regulation and include on/off power and heating-up lamps. The outer casing is made of furnace-painted steel and the inner vessel is thermally isolated with mineral fibre. The heating elements are composed of Nickel-Chromium (Nichrome) and the units include a clamp for retort rods.

Q = On the first few  uses, the mantle material turned brown and there was a burning smell - is this normal?
A = Yes, often this  will happen for the first 4 or 5 times it is used, until the mess material stabilises. It is probably better to use the mantles in a fume cupboard for the first few uses.
