Which problem are you trying to solve?

Inability to measure the melting point of a substance immediately after the analysis of another
Shortage of electricity
which interferes with the lab periods in developing countries.

How are you going to solve the problem?

I am proposing a new model of melting point apparatus that would have a mini solar panel, as an alternative energy
source and a thermostat to cool the temperature.

What is the impact of your project?

It will shorten the time taken to analyse the melting point of substances.
Students in these countries will have the
luxury of having an uninterrupted accurate analysis than that of the parafin wax.

How can the project be manufactured in the OpenLab?

Hardware prototype- with any 3-D printer that suites it, e.g. The BigRep One 3D printer
Electrical part- With Proma
Vacuum UV exposure box to make PCBs

Describe your project in detail

A melting point apparatus is an electrical apparatus used for the determination of the melting point of solid
substances.
It is used for qualitative studies in Science.
It works by supplying heat via a variable heater. This heat
melts the solid in the capillary tube gradually until liquid.
The temperature at that point is recorded. The temperature
is displayed on a digital screen. There is also a rapid heat switch and a hold display switch. At the top of the
apparatus, there are 3 circular holes in which capillary tubes are placed, it is then viewed from an internal magnifying
glass.
However, when one substance is analysed, it takes time for the temperature to drop so another can be analysed (
since we are not sure of the unknown's melting point, we cannot just place it in a hot environment).
My idea is
basically the addition of a thermostat to help regulate temperature , so another substance can be analysed almost
immediately
A thermostat is a component of a system that maintains/ regulates the temperature of the system at a
particular desired state.
Hence, to achieve my goal, I will employ the use of a thermostat.
However, as good as the idea
seems, many students in developing countries cannot harness this without abrupt power interruptions. Therefore, there
should be an alternative energy source that would also favour the ecosystem- Solar energy; it is renewable and unlike
batteries, are not toxic to the environment. So, each apparatus can alternatively run on solar energy trapped by
affordable solar cells that converts the solar energy into the use able electrical and heat energy.

Excite more the audience , try to clear it more , good luck !!

Thanks @yassineaskri.
The aim of the project is to provide a faster solution to melting point analysis and also create a
model that runs on alternative power. I have worked with a model that took time to cool and so I couldn't analyse
another substance immediately. This affects a lot of students in some countries.

Great idea .. It is also possible to put a segment that focuses the sun rises at one point and that helps to increase
the speed of heating and this could be an alternative if the device is exposed directly to the sun rises

@Omarhasayn89, thanks a lot. That's an awesome contribution. Since one of the foci of my project is time saving, we
wouldn't want to waste time on charging, hence your idea is really in line with my aim. I believe the mechanism
will be similar to that of a condenser in the microscope to fix as much rays as possible to a point.
Thanks a lot!!!
