DPD powder storage

I can see how you like the bottles. Similar to the Taylor ones that you can hold in one hand and flick open the lid with your thumb without it flying away. I do prefer this design over the Clear Choice Labs bottles with a screw on lid, and I think the Tftestkits ones are similar.

I buy in bulk and after a few refills or if the lid fails the powder clumps. So as soon as i see that happen i change to a new bottle.

Maybe store the bulk supply container in a sturdy zip-lock baggie or a large wide-mouth bottle?

Yes the large bulk bottle is stored properly in a cool-dark-dry place. Its not the large bottle that clumps, its the little re-fill ones. Probably people dont realize that the lining on the small bottles of DPD powder is a desiccant agent and like any desiccant it will get full with humidity and stop working, hence my TIP to use leftover bottles from blood testing strip, and just like that. Its a Tip.
