It makes a difference when it comes to the heating mantle. If it's for a practical using a flammable chemical with a low boiling point (as is the case where we don't use bunsens) there are other ways of heating it. It may not be a big issue if it's 1 heating mantle but a set of 6 would set you back a bit!I have no idea. The teacher in question is a chemist so fully capable of doing it. Just wanted an idea if I'm pricing up one set or six.
Could you tell my teachers that please ?!Joint clips (not to be used when bunsens are used for heating)
Our 6th form do it as a PAG and work on their own but we also have lower year groups that have it as a demo. One of the teachers has a lesson just letting them set it up so that the students get familiar with it as it can be a bit fiddly the first time they use it.Perhaps you can answer my other question. Is this normally done as a demo or could it be done in groups If you have enough sets.
you can get metal ones.
The teacher asking for said equipment is also the teacher who melted the joint clips whilst doing distillation.Other things that will be useful: Joint clips (not to be used when bunsens are used for heating) PTFE joint sleeves are useful if you are doing things like refluxing with NaOH or other corrosives that love to attack ground glass joints.
Mantles are safer for heating when using a flammable solvent, which is often (but not always) the case when carrying out refluxing or distillation.Didn't even realise you could do distillation with the mantles. Ive been a tech for three years and have only been told to set it up with bunsens but that's more to do with my senior not wanting to change her ways.
