GelRed Nucleic Acid Gel Stain

Hi Everyone,

My year 12 Chemistry teacher has asked me to purchase some GelRed Nucleic Acid Gel Stain - 10 000X in Water. Trial size (0.1ml).

Can anyone advise me on where I can purchase this. I have sent several emails to various companies with no results.

Thank you.

Hi Everyone,

I have been asked to buy a Mole Box. I had to google it first as I had never heard of one. They do exist, but where do I buy one from? Anyone know? The ones I have seen online look like they have been hand made.
