Most of these kits are currently out of stock. is there an eta or more stock, please? thanks.

I don’t have any information you can call apera instruments they should be able to help you with your inquiry.

Why can't i bay this calibration kit and get it delivered to silkeborg denmark, when i can bay the apera pc60 and get it delivered. it doesn't make se

Perhaps this company doesn't have an export license?

Does refrigeration after opening extend life of solutions?

I never had and it's been fine.

Would the buffer solutions and storage solution work with the Extech pH meter?

I would think it would work with your meter providing what you are trying to buffer falls within that range. The storage solution should work with all meters. I would contact Extech and confirm with them to be 100% certain.
