Wow Bigmack, I hope your school appreciates you!!!
That is a fantastic set up, especially for the cost!

Hear Hear!

Anybody know of an affordable drying oven? From what I can see, starting price is about $2 000, ouch. It is to be used for drying out chemical samples, we would carry on using our incubator for agar plates, etc.

who would blindly follow a document that is so out of date I could not agree more - I managed to get it in writing (indirectly) from my HT that he prefers me to follow RiskAssess, especially when it comes to health risks. I also prefer my old-fashioned diary and prac book for orders and scheduling....

Thanks Alice!

Two things - Firstly, the old grey trays are photographic trays, not cheap, but, yes very durable. Try your visual arts teacher to see if they have a photography catalogue. Secondly, the ABS trays aren't dishwasher proof. Found out the hard way :-( I must be lucky then, mine have gone through the d...

Even if a school is an account customer, we do require proof of ID of the contact person for each order. This is forwarded through to the Police Dept. Note that different states have different regulations regarding End User Declarations. Alice/Westlab - is there a link to all the products (chemical...

We have bought ABS trays from Haines, been about 4-5 years ago, they've lasted well. We've also got the same grey ones, they are indestructible!

We went with Pasco, represented by Ciderhouse. We've bought a lot of equipment, mostly sets of 8, thanks to the funding from the P&C. The Bluetooth connectivity is life changing for the students, it has created so much enthusiasm. Apart from the pH probes which have been a bit problematic, we're...

So sad.....

I haven't tried it, but if you go to YouTube and search for "How to Get a Cork Out of an Empty Wine Bottle" it shows a method using a plastic bag. Let us know if it works!

Yes - I diligently take it all home and drop it off at Woolies when I eventually get there... I think my staff room thinks I am absolutely crazy but so what! All the little things count much more than the big things that politicians promise but never deliver!

Great suggestion, thanks kimmy!

I've got a lot of teachers wanting to do the Baggie Science experiment - CaCl2 or DampRid mixed with Bicarb soda and Universal indicator in a Ziploc bag. Any ideas on how I can reduce the plastic bag footprint? Last year I washed out all the bags and reused them as many times as possible but some te...

That's why I am wondering as well, Merilyn1! Turns out there are quite a number of these drawers scattered around the old building, they've been stacked neatly so the lead was invisible. Sometimes I'm too scared to open unused cupboard doors, a treasure trove of headaches! Bigmack, I'm relieved I'm ...

Can anyone enlighten me? I have no idea why these trays/drawers were designed like this. The bottom half is empty and the top half is lined with lead. They are part of custom-made shelving and one is in my chem store room, holding lead nitrate bottles on porcelain saucers. They are also very heavy! ...

Nice, Macca!

Has anyone had any experience with Sustainable School Shop?

Oh bigmack - that's dreadful.... Stay safe and good luck! To you and everyone else

I think I should go into the Silver Nitrate black market. I have been here 20 years and have NEVER purchased a new bottle of Silver nitrate. I have 475gms of silver Nitrate still left At $100 + for 25 gms I am sitting on a fortune! Even at around $400 for 100gms its worth a lot. :w00t: That is one ...

This morning Bob Death came to the North Shore and spent a couple of hours repairing and assessing equipment for me. I don't know how much it will come to, but I have a large pile of back-to-life equipment! So much cheaper than buying new, and so much better for the environment :clap3: I'm sure thos...
