FNG here and after lurking and learning for a few months I have a couple of questions that I haven’t been able to get answers to yet.
1) What form is better for longer term storage (say 1-2 years)? Powder or finished product? Any substantial difference? After seeing lots of posts swearing to never use syringe filters again I’m going bottle top filters but it seems like a waste to push just 100ml through a 500ml filter.
2) I’ve noticed minimum order limits on suppliers and wonder if there’s a weight limit at which you should keep your order under? I would think a kg total package order would get more attention than a 200g order. Suggestions?
3) Pharma test that I’ve seen has always used CSO as the carrier yet it seems GSO is vastly preferred/discussed. Anyone know why? I would think pharma uses CSO for a good reason over anything else.
Thanks!
