Re: MTA products going downhill fast?

We have found Bill from MTA so good to work with. I simply send him a list of my requirements, he sends me back a quote for the items. I have had a few items that were not good quality, a phone call copy of invoice and replaced instantly. MTA are probably just like everywhere else at the moment and ...

Funny how it i...

Re: Best M.W. information

If in doubt, make your own calculations using the molecular weight of the chemical. I have to rush off to a meeting now but I'm sure someone else can explain. Once you do this, you'll wonder why you ever had to look it up! :thumbup: Yes i know how to do this but even these are different on differen...

Re: Phenolphthalein Agar

i know this is a old old post but i have just came across a great idea of how to prepare the squares for the diffusion experiment.
K mart have silicone ice-cube molds that are perfect for the 3cm square cubes then students can cut another one down to get a 2cm square and 1cm square.

Heat the solution in the microwave on high for 30 seconds. Remove to a heat-safe surface using a hot pad or oven mitts, ...

Re: Plastic dropper bottles

We use a mixture of both glass and plastic dropper bottles. The only chemical that is a must for me with the amber glass bottles is Silver Nitrate and Iodine Solutions. '
I have got my plastic bottles from both MTA and Westlab.
