Open Source Heating Mantle

Basics

• Part of the Open Source Laboratory Construction Set
• A Device with a Semispherical Cavity in the Top
• Open Source Round Bottomed Flasks can be placed in this cavity
• When the temperature setting is changed, or temperature drops below a certain threshold, the coil of wire around the cavity is turned on and the flask is heated
• It is cleaner than a Open Source Heated Labratory Bath, yet more efficient+consistent than the Open Source Hotplate making it preferable for many use cases

Used For

• The Open Source Laboratory Construction Set

Industry Standards

• This model by Thermo Scientific

Existing Open Source Designs

• This instructtable needs some improvements, but it could be useful

Minimum Viable Product

• Safe (IE no exposed mains power, or exposed heating elements)
• Have the first on built to a 1L Capacity Round Bottom Flask, but have the desigm be scalable
• AC or DC Power Inputs
• Fast
• Efficient (As Possible of Course)

Basic Design

Power Supply

• Takes in the AC or DC power and converts it down to what the circuit works off of

Control Panel

• Arduino/Rasberry Pi can monitor the temperature and adjust accordingly
• Add dials and a cheap LCD for interface

Heating Componets

• Nichrome wire around some sort of insulator
• Custom Ceramic, or a Fiber Ceramic, maybe both?

Shell

• 3D Printed Box all the above componets fit in
