#1 Science Forum For Lab Technicians

It would get my dogs pretty excited if I left a chunk of meat out in the back yard. Years ago when my daughter was doing her undergraduate degree, she had a job working in the entomology department looking after the flies. It was very stinky!

I asked our local mineral club. They were quite happy to come out and help me with identification.

Wow those are fantastic!

I am wondering how well the egg white, or agar would come out of the silicon trays? (I've never used silicon trays). Does it come out easily and smoothly?

I bought a bunch of the photography trays a couple of years ago. Unfortunately they differ in size from the old grey ones. However the colours are pretty and I can use the colours intentionally to differentiate different groups. They seem to be lasting well although I doubt they will last as long as ...

Hi all
We have one high voltage power supply which is used by teachers only. After an incident a couple of weeks ago, when the teacher forgot to turn it off before removing the leads and consequently suffering a shock, (he puts it down to tiredness as he has young kids who were unwell) we now are ...

Its not just the excessive number of test tubes, but also the amount of horrible chemicals that you then have to dispose of. Are they doing the experiment individually, or with partners?

Not sure why the picture won't open - I tried my best!

They are for glass pipettes eg 25ml, 50ml size.

If you would like them RosalieL can you message me your address.

Hi
Is anyone interested in these pipette racks we no longer want? I think they come apart so could be posted.

I ordered one and it is already on it's way. They were super helpful.

We've also used Cane toads from Dissection Connection

Good morning
We are hoping to purchase a Rubens Tube but I am having trouble sourcing them. Has anyone purchased one recently and if so, where did you get it from?
Thanks

I use one but I guess I'm a bit old fashioned and I like to be able to easily see the day/week/month. (I still use a paper calendar for personal use). I use an everyday diary which works fine.

Good morning
How do you store your pH meters? Currently I have them sitting upright in their little bottles of storage solution in a bigger container. I have just found one in the container but not inside it's bottle of storage solution :mad: Wanting to look at other ways to store them so that is ...

I'd be reluctant to have bromine around - bromine water is horrible enough.

Hi all

Has anyone bought micropipettes recently? If so, where did you buy them from, what brand, are they good?

Thanks in advance

Sodium benzoate papers are apparently safer.
My teachers are doing a taste test with brussel sprouts!

Think I would be giving the teacher a list of chemicals that you actually have - only buy new things in if they are going to be used regularly.

Ohh those wheels from Bunnings look good especially for the price.

Has anyone bought a trundle wheel recently? If so are you happy with it? We bought 2 a year ago. When I got them out to use recently I discovered both of them have lost the clicking mechanisms. No idea where or when - no doubt down on the field somewhere, and not reported at the time.
