00:00If you run a high-temperature lab, you already know the furnace is only half the story.
00:05I dug through the listings and found the best deals for muffle furnaces every high-temperature
00:09lab needs, here's what's actually worth your bench space.
00:12Start with the part that fails first, your temperature reading.
00:17This K-type thermocouple comes in 150, 200, or 250 millimeters, rated to 1,300 degrees Celsius,
00:24and it's $8.13 with 4.9 stars from almost 5,000 buyers.
00:30Swap it in, get your furnace reading true again, and stop guessing whether that's really
00:341,100.
00:35If you need the furnace itself, this 1,150 degrees Celsius unit runs on 110 or 220 volts, pulls
00:431,750 watts, and holds constant temperature.
00:46The part one love is the observation window, you watch the melt without cracking the door
00:51and dumping all your heat.
00:54$236.75, 5 stars, nearly 5,000 sold.
00:59Then there's safety.
01:01Extra-long non-slip crucible tongs, stainless steel, $7.14.
01:07Long enough that your hand stays well clear of the chamber, and the grip doesn't slide
01:11on a hot crucible.
01:13Cheap insurance free your fingers.
01:15Dental lab or burnout work?
01:18This aluminum band heating element is the spare you want sitting in the drawer before the old
01:22one dies mid-batch.
01:24$6, 5 stars, over 4,000 sold.
01:28At that price, buy 2 and forget about it.
01:31And the crucibles, 99% high-purity alumina, square, side length under 60 millimeters, with
01:38a convex inner lid.
01:40Corundum takes the heat and won't contaminate your sample.
01:43$3.04 each, 5 stars, 4,200 sold.
