Can you send me the spreadsheets you use i am very interested as chemwatch has been very unhelpful

Hi, Having fallen into the job like a fair few labbies in school world i took on the job nearly 2 yrs ago. We have just a WHS audit and have done pretty ok out of it all considering what the area was like when i started working. One if the few things that i did know had to be done but wasnt was a Ch...

Hey guys, Just a quick question... How often do you clean your chem store?? I have 2 Chemical stores on in the senior upstairs part of my building then one all the way down in the middle school. Time seems to get away from me some days but I know its a job I should be doing, I just wish we didn't ge...

We use the matrix too

Hi guys, Like many others I was unaware of the GHS labelling compliance stuff. I work 16 hours a week in a high school of about 500 students. So if I am printing my labels off of Chemwatch for things like dropper bottles and it doesn't have a pictogram that makes it non-compliant? Sorry for the lack...

Hi guys, hope you are all well with the last rush before the holidays, 1.5 wks to go for us. My HOD has approached the robotics teacher and I about a SASTA grant for the national science week with the theme of ‘Drones, droids and robots’. We are currently running a robot program in year...

Hi, I had a teacher do a demo of iodine sublimation while i was away, with the aftermath left for me to clean up with a note attached that says sorry i didnt know what to do with this...?? do i write it off and pout in chem disposal or i think i read somewhere sodium thiosulphate sol until clear and...

Oh I feel for you all without air-conditioning! it seems crazy that in this day and age you don't have any and the weather here has been consistently hot. All my labs and prep rooms have A/C. I think every room in the school does. Id push the chemicals getting too hot opinion and see what they say

Hi guys, We have just signed up for risk assess for our high school or about 550 students. I run 7 labs with 3 prep areas. I have scanned the pdf briefly that they send out but I want your tips or tricks for something that I hope will change the way pracs are done in this school. Is there a way to c...

hey,

Yes back into it, we had week zero last week but mostly staff and faculty meetings with some very boring IT stuff. Hope you all have a great first week back and I look forward to hearing all your great advice this year.

best option to clean up said beaker after amazing sugar and acid reaction?? I am currently soaking hoping this will help but the teacher did the prac while I was away and it was pretty crisp when I go back

thanks guys,

yes thinking the board with nails I have seen a picture of it

We have just inherited a 4ft tank and was wondering what you thought about some uses for this.
Keeping in mind if its alive I will have to feed it during the holidays

Thoughts??

yes unfortunately the labs are used as general classrooms more often then they should be so I don't leave anything in the labs at all.
the trolleys are always ready to go and kept in the labs store that sit in between each set of labs. I have downstairs, upstairs and middle school.

Hi guys, Just wondering how you store your Bunsen burners? We currently have 3 separate sets that sit in a tub on a trolley in-between each lab area and im slightly worried that they may get put away when the are hot even though common sense would say not to. Any suggestions? I have seen a peg board...

Just wondering what qualifications you have. I have taken over this lab tech position nearly 18 months ago it was only meant to be for a term but have been put on a contract ( hopefully permanent soon) and am looking at doing some training i did science at school and started a science based degree b...

im a sso2 in a school of about 500 but only working 16 hours a week and the only technician at this site, train by the person who was in the job prior to me. Im not sure there are many from SA on the chemtalk website even though it is a great tool

the hydrogen peroxide will start to break down esp in light, put in your chem store in the dark. You may also get a bit of gas produced and this can cause the tops to 'pop' off your flasks if they are tight. Just leave a little gap with your stopper and dont put them on to tight.

it would work with just distilled water and your acid ( the hydrochloric) and your base (sodium hydroxide) to put the pH up or down without the hydrogen peroxide though a fair bit of fiddling

yes, Is this the prac you are doing? the enzyme one?
