I've got these long glass rods that I would like to cut/snap into shorter length rods for a heat conductivity experiement. The thing is these rods are about approximatley 1cm think are quite hard to snap. Does anyone know an easier (and safe) way to cut or snap glass? //EDITED by adam. Reason: make ...

Silver nitrate test is halogens, mainly chlorides, bromides and iodides.

Have a fun and safe holiday everyone!

I'll be attending a seminar on physics, admin and afew other topics that I can't remember. It's held at Bass Hill High School.

I have a few specimens that are still stored in formaldehyde (most of them need topping up). I have been asked to replace the formaldehyde with 50% enthanol solution but the head teacher is abit concerned with the handling of formaldehyde. Does anyone know of a place that will do the solution change...

thanks Juliem

I have a storeroom that has an extraction unit but this room is used to store general equipment. I have 2 prep rooms, though 1 is not in the same main science building. Since space is a problem I think that's why the previous lab asssistant aranged the chemicals in that way. Thanks for sheding some ...

Hi All! I've just started this job and I have all chemcials stored in the same cupboard in alphabetical order. :? I have left it the way it is for now since I have very limited space. I want to sort them but I'm sure about the regulations with chemcials. I do have the CSIS package but I haven't real...

Thanks Rae

I'm in the process of making a set of laboratory rules that I would like to print as posters for all the labs and also give a copy to the junior students. I was wondering if anyone else has done this? If so what are the rules in your labs?

Conc. HCl worked like a charm.

Thanks for the help guys.

Once again, gotta love this site!

Does anyone know an easy way how to remove rust? I have a whole heap of test tubes that have rust stains inside them that I can't seem to remove. I've tried soaking them in 50% acetic acid solution then dilute HCl and they are pretty much the same. It would be such a waste to throw out all these tes...

I totally agree with you Mother. I have previously worked as a chemist but I've only been a lab assistant for about 6 weeks and I sometimes wonder how people without a science background cope with the job.

I was very surprised with level of pay. I assumed it would have been alittle higher.

i just have my sodium metal stored in a glass jar with a glass lid with some kerosene inside to prevent it getting exposed to moisture in the air.

I stumbled across this website about gloves. I think you should check it out.

I hope this helps marilynm.

If you have allergies then I would recomend using low powdered gloves and also cotton gloves underneath.
