I learnt a good trick from some colleagues in Queensland schools.
Bundle 5 or 6 test tubes together with a rubber band and only use one dishwasher spike to hold all of them. It works a treat!!

No luck
I removed the pack panel and cleaned inside and still nowhere even approaching 100%.
I think it's a dead duck.

Thanks, Richard. It's good to be back (most of the time). I made sure the tube is totally clean and no blemishes but didn't think to check the light path. There is no mudwasp in there :crazy: and you can definitely see the light source but even with nothing in there I can't get 100%. I'll give the s...

Here are the instructions.

Hi to the Brains Trust. Yes I'm back at my old school but that's a story for another day. Can anyone help me with this colorimeter please? I hope I have attached the photo properly. I have followed the instructions a couple of times using fresh solutions each time but I cannot get it to read 100% tr...

Thank you for the good wishes.
Good luck, Laverne - I wish I was retiring but still need to keep working for now.

Thanks guys. That means a lot to me.

So after about 26 years in this position, I am heading to Queensland to work and be closer to family :clap3: :thumbup: :wub: I have part time work and hoping to pick up some casual as well. [-o< :beg: It's the strangest feeling, as I have been here for so long I feel like part of the furniture. Than...

The dentist sounds like a great alternative.

I am planning a move to the Toowoomba area and will be looking for school lab work there, so if anyone has any connections it would be appreciated.
Thanks

Only because I had a clean out not long ago and bought some shiny new ones!
I have the old grungy, bent and dodgy ones stored away for various metal experiments. They come in handy sometimes.

Thanks, Richard.

I was looking for some the other day and I think I found the right ones on Bunnings website. I haven't bought any yet. They were hard to find!!

I had a flask with something in it that I was not going to let beat me. I ended up putting some smallish gravel in it, swirled it around a bit and it came off YAY!!! That was after soaking it to loosen it up a bit.

Our SAM is our supervisor and I'm attending some training with her next month. Until then just keeping up with what comes out in emails and in Schoolbiz.

I used to put it in one of those tubes that you filter fish tank water through and pump the water through it. It would go green and slimy and I would throw it out. No question of reusing it.

Same here. We have some really old ones. I have thrown out the worst of the yellow ones and the broken or unidentifiable ones. I wouldn't be concerned about them deteriorating in 12 months or even 5 or 10 years. Store them safely and they'll be fine for many years.

I used to use it to filter fish tank water years ago when I had smelly fish tanks and yabby tanks in the labs. Thank goodness we don't have them any more!!

Welcome, Donna.
Yes the labbies in Tamworth really are amazing, and a great bunch to have on your side. You can't go wrong following their advice.

I have a stash of slightly blue slides that I reuse.
