Re: egg membrane

We use 6M HCl - it is fast - needs to be watched , eggs need to be moved so time intestsive. they work better that way than using vinegar or 1M HCl overnight - the vinegar makes the eggs swell and reduces the effectiveness of the osmosis (the point of the prac).

Re: Finding Items in Officemax

I agree their site is not user friendly - if you know the cat numbers it is a treat if not - grrr time wasting in my opinion.

i get a hard copy sent to me each year of the cat and get the numebrs i need from there and then go to the order section and order that way - not as time consuimg trust me :)
