HI I realise its the last day of term and I am sooo ready to be gone already but I just recieved my new autoclave and it is one that requires and external heat source, any suggestion as to what I should be using/ getting ?

well I did think of that but pyrex doesnt melt does it? becasue it's high hest resistant. I may be wrong

Yeah I got a bunch of beakers about a month ago think I ordered about 4 dozen. Have lost about two dozen they crack when heated and the lips keep chipping leaving sharp edges and so I have to toss em. picture in the catalouge showed SCHOTT DURAN brand what I got was BOMEX and it's S%#T. This didn't ...

I only keep bunsen burner, heat mat, tri pod, gauze mat, retort bosshead and four prong clamp under our benches. Even this is annoying because the kids NEVER put them back where they got them and instead of getting the kids to look under all the benches teachers always come and complain to me that t...

My prep room is a bit of a mess now. I taped a plastic petri dish on the top of it and put some wood shavings and some polysyrene balls in it hehe MESSSY Did I mention I'm excited?

In my excitment I didn't see the big heading in the manual that said RUN THE MACHINE FUN IS GOOOOOOOooooo

Hi all WE JUST GOT A VAN DE GRAAF GENERATOR!!!!!!! :clap3: :w00t: :clap3: EEeeeeeeeeeeeeeeeee sooooo excited !!! BUt I have no idea how to use it safely!

wow Kel you know what teacher are planning week one next term!

I work in an independant school. ALL staff have their first aid certificates (paid for by the school) but I'm pretty sure one or two of the office ladies are the designated First Aid Officers (the one's that get paid the extra). I think it's a good idea to that every one has their certificate becaus...

I have these botles and they are fantastic!!!I keep all my indicators and stains in them. I have a food prac tomorrow and they need benedicts solution, ethanol, NaOH and copper sulfate, sooooooooooo much neater and easier to use that stock bottle and droppers ! I got a big pack of 50 75ml ones for o...

on further investigation it's not the actucal probe at al it is the unit itself. I switched the probes from one of the working ones and it's still not working, hmmm will have to track down a supplier.

That's the thing I don't know where they came from! They were ordered befor I started here last year ( by a teacher whos nolong working here) hmmmm
Lol

calibrated with a mallet

ok so after some research im gunn just guess that the probe is stuffed, by the looks of it the meter I have has replaceable probes so i will have to go looking for a replacement

Hi all, Im having a bit of a problem with one of my pH meters. I was calibrating them all befor a prac today and one of them is doing some weird stuff! when placed in the pH7 buffer it quickly goes to a pH -0.8 where all the other meters go to pH 7.1. does anyone have any idead whats going on and if...

Wea ll have them but not everyone wears em and they are all the same colour just have the school logo with your position and your name

The maintenance man just came to se me and had informed me that the tap was fixed two weeks ago and wanted to know if anyone had bothered to check it, hmmm we shall see at recess if it works or not. Hmmm would have been nice o have been told that it had been looked at , comunication break down much?

Yep! but thats because I dont go to the morning meetings with the teaching staff (most of it is irrelevant i.e. which student is on detention/suspension, when reports are due etc) and i rarely venture down to the front office.

Thanks for the handbooks Kiah! might have to suggest something like this for my school!
