Intro

This instrument is used to heat up solutions or materials. They usually are equipped with a magnetic stirring mechanism. They can also be equipped with a thermometer feedback device.

Heat Plate I

Heat Plate I

This simple plate has no temperature feedback mechanism and is the simplest to operate. It possesses a magnetic stirring mechanism. It is recommended to use this one if you are not looking to set a very precise temperature. (no 100°C is not a very precise temperature 67.3°C is though)

Functions

A) Temperature setting button.
B) Rotation setting button
C) Temperature display and warning. You will see the temperature you set-up here.
D) Heating zone (Warning it stay hot for a while after being done)

Rules

1) Do not leave any heating operation unattended.
2) Do not heat inflammable solvents.
3) If heating something make sure people around know what you are doing. Communication is key!
4) Please leave it clean and at its place when done.
Heat Plate II

Heat Plate II

These plates can achieve precise temperatures thanks to the temperature feedback mechanism they have. They also possesses a magnetic stirring mechanism. We have two of them operating in the same fashion: One large and a standard one.

Functions

A) Thermometer feedback mechanism. (described below)
B) Temperature display
C) Temperature setting button.
D) Heating zone (Warning it stay hot for a while after being done)
E) Rotation setting button
F) Holding bar for the thermometer feedback mechanism.

Rules

Same rules apply than the Plate I but add to this:

1) Do not use without the thermometer feedback mechanism. (make sure it is correctly plugged in the back)
2) Make sure the thermometer feedback mechanism is inside the liquid. SUPER DUPER IMPORTANT !!! (explained below)
Thermometer feedback mechanism (or probe)

Thermometer feedback mechanism

This instruments goes in pair with the heating plate II. It will sense the liquid's temperature and communicate with the plate to increase or stop heating. It is important to correctly dip it in the liquid. Failing to do so will lead to the thermometer "thinking" the plate is not heating enough, causing the heating plate to increase the temperature to the max. This can cause the liquid and its component to be degraded, the plate to be damaged and in the worst case scenario something to catch fire.

Functions

A) Current temperature
B) Set-up temperature
C) Adjustment buttons

How to operate

1) Make sure the probe is plugged in the back of the plate
2) Make sure the probe is dipping in the liquid (at least 5cm deep)
3) Turn the plate on. The device will turn on.
4) Set on the probe the safety temperature (The temperature it should shutdown if the liquid would reach it. 20°C above the temperature you want to reach is good enough). Wait some seconds.
5) Set on the probe the temperature you want to reach.
6) Turn the heat button on the plate 30°C above the temperature you want to reach.
7) Wait and keep an eye on it until it reached the desired temperature.

You can always adjust the temperature during the operation but you can't change the safety temperature.

Tips

It's always better to use a "bain-marie" (or hot-liquid bath). It will keep the temperature inertia and heat homogeneously your solutions. You can use water if you plan to heat under 100°C. You can use oil if you want to heat above 100°C.
