Please advise the expiration date for biopharm buffer calibration solution kit 3-pack of 250 ml (8oz) each ph 4, 7 and 10 calibration standards color

The buffer pH 4 and 7 have a shelf life of 2 years when unopened. The buffer pH 10 has a shelf life of 18 months when unopened. These expiration dates are assigned before they head to the amazon warehouse so you will have slightly less than that.

What would be the shelf life after the biopham calibration solution is opened?

I think each bottle lists it’s expiration date on it, which we treat as it’s expiration date whether it is opened or not. How long that is depends on how long it was between manufacture and shipping. I think most of the time this probably has about a year shelf life once you get it, but that would be variable.
