help with Hanna phosphate checker

[Maverick00]

Ive always had the same problem with the hanna regardless of wiping down the glass tubes or not. I havent used it because of this for quite awhile. Interested to hear what others say.

EDIT - 3 mins max? Hm that could have played a part, I dont remember if i was that fast or not.

And for C2:, be sure to hold the button until the 3 min timer appears. My results don't vary at all, usually the same or .01. That is if I do it right... As mentioned, have to get all the powder in cleanly, and needs to mix clear. And no fingerprints. Takes a little practice to get your routine dialed. But after that, very easy, actually.

I find the challenge is to get all the regent into the sample vial. Any tips?

I cut the top off and bend the middle of the package into a v type funnel and tap it in , also makes me feel like a scientist

Cut the packet, and shape a funnel on the side. Hold the vial at an angle, not straight up and down. Then gently tap the back of the packet with your finger. And be sure the insides of the packet are opened, too, so the powder doesn't get stuck coming out.

And I think someone said it before but clean the vials off with a cloth the finger prints or salt water on the outside will give you a false high
