JOANLAB Electric Laboratory Heating Mantle with Magnetic Stirrer, Digital Temperature Control (1000ml/350W)

The JOANLAB Electric Heating Mantle with Magnetic Stirrer and Digital Temperature Control is a reliable and efficient lab tool. The digital temperature control ensures accurate results, while the magnetic stirrer maintains consistent stirring. It heats evenly and quickly. Highly recommended!

Easy to setup. Works well. Heats very evenly, even if not quite as quickly as one might like.I’ve used in one synthetic experiment and it worked great.

Cost is fine. I measure a good bit of difference between my Fisher thermometer and the displayed mantle reading. "Bowl" is not entirely concentric while my Pyrex 1000ml flask was inside. For some of you with concerns about the thermocouple supplied, may I suggest making your own with the properly fused end and the, say, K type (or other) for the expected temperature range. Since most are Teflon jacketed (or other thermoplastic), obviously, make sure the tip is sealed in silicone or other inert material immune to your "bath". My unit didn't come with a manual. Joanlab wants me to sign in for an inquiry. Don't think I'll take that path. Aside from getting a SOLID mantle, like something you'd find from Fisher, or other, and TONS more costly, I can deal with this. You just have to be creative.

Good product for its price. You cannot heat without the thermocouple plugged in. If the thermocouple malfunctions or breaks you’re out of luck. The thermocouple is being advertised as sealed with nickel/platinum probe end. The nickel platinum holds up and only corrodes slightly while being subjected to nitric acid but the internal wires are very susceptible to vapors at the joint where the supposed seal is located. In a matter of seconds nitric acid vapors will corrode the internal wires at the joint rendering your apparatus useless. If you leave the thermocouple out but plugged in it will max heat. There is no manual heat control. I find myself frequently having to throttle the heat with the on/off switch.

I have purchased two heating mantles (2000ml and 1000ml) from this company and I am very satisfied with both purchases. The first one is still going strong after 4 years. Both models have good temperature control and the stirrer speed control works well too. The heater has adequate power to quickly reach any desired temperature target. I would not hesitate to purchase this brand again in the future.

Works well and easy to use

None of my work can have any metals involved. This mandatory censor probe renders these units useless to me. These units will not even turn on without the censor plugged in. No instruction come with this unit to explain the digital abreviations displayed.

I'm pretty happy with the value/performance ratio here... You get a reasonably well built product and temperature control for the money... I've only used it for about a week but so far I'm pretty happy with it.
