Hi, I hope to be fine Aly

The Best and cheap company is  Sigma-Aldrich Company . Its  pure natural products are Reliable and had references and for  high analytical chem..

Dear Dr Nehal,

Thank you for positive response. However, my student contacted Sigma but the price is very expensive for her, imagine 10mg cost more than L.E 2000!! if you know someone else cheaper than this price  we will be happy.

Best regards

Aly

I think for your laboratory / Department there must be some suppliers who supplies not only routine chemicals but also specialized chemicals. Why don't you ask this question to them rather than using the clipboard of Researchgate.

A nice day to you

Thank you for your question we have a cheaper place to buy so please contact me.

Best regards

Thank you for help
