Re: Acetic Acid 1M to 0.1M
For the 1M, just dilute it ten times. ie take 100mls and put it in a 1000mL measuring cylinder, then add water to the 1L mark.
The 2M would be diluted 20 times. So take 50mLs and add water to the 1L mark.
cheers, Ellice.

Re: spreading infection
Where do you buy this thing called 'Glitter bug'?
Sounds like a cool experiment!

Re: split pea DNA
We always use split peas, blend for about 15secs with water. I'm sure the recipe is on here somewhere.

Graph paper suppliers.
Hi all,
I normally buy graph paper pads from OfficeMax, but the last lot came without the 1cm grid lines.It is difficult for the students graphing, and I am looking for another supplier. Anyone have an alternative?

Carbon electrodes
Hi all in labbie land,
I have a stack of carbon electrodes coated in copper. A casualty of 'that' experiment. Any hints on how to tidy up.
Thanks in advance for any help.

Thanks for the suggestions. In the end we broke up some plates, and the kids had to put them back together (not glued, just in place). Went well.

Re: prac class
We put air locks (with limewater) on top of the flask. The air locks can be purchased from the home brew shops. Weigh the whole set up before and after.

Re: Help Please- pH solutions for enzyme pracs
Every year we seem to try something different, and each year results are interesting! This year I'm going to give them the Hydrogen Peroxide with either HCl or NaOH added to desired pH as recommended. But, would that affect the Hydrogen Peroxide?

Pulse Oximeter
Hi all in Labbie land,
One of our Bio Teachers is keen to purchase a pulse oximeter. Is anyone familiar with these, and where to buy one? I'm thinking medical suppliers.
