Tubing Borosilicate Glass, 5mm x 0.5m pk/10

Thanks. Haines doesn't seem to have any with capillary size inner diameter. I think I want about 1mm internal diameter.

Glass pasture pipettes would do the job, snap off the end bit

We use the glass pasture pipettes

My register/stocktaking document is off the Vic ed dept site. It is in alphabetical order, it tells you chemical/substance, room for amount, container size, strength, hazardous substance, dangerous goods, dangerous goods class with description, sub catergory and packaging group. eg Acetic acid glac...

Going through ours ATM There are Hydrogen Peroxide ones for 3% ,6%,9% and 35% . (LOL all from Chemwatch of course ) I see they are stored in the fridge . Now it seems that the lower strength ones are in Risk assess labeled bottles and presumably made from diluting down the 35% solution . I was unde...

As a basic rule , if you have a litre of 1M HCl you can pretty well neutralise most of it with 1litre of 1M NaOH . If you have 1litre of H2SO4 1M it will take 2litres of 1M NaOH or 1Litre if 2M NaOH .(because Sulphuric has twice as many Hydrogens ) But …….. iff’n you are going to sit there and test...

wow... just checked out the Flinn science thing you posted... full on. Basically we have ours in their DG cabinets and segregated where needed. All the rest that are class 9 or no class are done alphabetical. Powders and dry chemicals on higher shelves, all liquids down lower and in bunding incase o...

Ciderhouse tech...... so much fun to play with

Soak them in a bucket with nappysan overnight at least, then throw in the machine. What comes out comes out and what doesn't - depends how fussy your school is. President lab coats sell theirs for a pretty good price and great quality if you need to replace. These ones are brand new! This was the f...

How did they go today ?

We use 1M for the Gal cell prac, works a treat, any lower and sometimes it's hard to see a change unless using digital multimeters.

Not sure about hard and fast rules....but we have removed all mercury from school. It came in about 10 years ago that mercury was being banned in research laboratories. Follow their lead, chuck it all. There is no reason you need it, so reduce your risks.

We get our rats from the pet store. Snake food, already dead and frozen, don't stress.

Ahh yes I know exactly the ones... the other one I know that broke was just your standard old Winchester. I think it stored acetonitrile before can't comment on age though. Personally I think someone was cleaning in the fumehood a little to hard and knocked the bottle against something, then a littl...

That's 2 winchesters I have heard this happening to in the last 3 months... never in my life as a lab tech has that happened before. I would suggest everyone check their old bottles. Maybe they are not as good as they used to be. I'm also going to be checking each new bottle before it gets put into...

I can find out... please stand by

I'd chat to Westlab first then go from there

We use a laminated cards with little circle on it that we made up. We also use food dye with a little bit of Glycerol in it so it doesn't run all over the place with surface tension. You can have a few different cards with different volumes. We also have a lot of old well plates that we roll out and...

It is quiet here I think that means we are all organised and haven't forgotten how we do our roles after such a long break

I'd be going with what @melsid said... perfect
