Where to get PH buffer solution for PH meters?

[chongj88]

Sorry if this has been asked before... Can some kind soul please let me know where I can get them?

Thanks in advance!

you are referring to the PH4 and PH7 solution?

that would be Rainbow, C328, Petmart, Havelock, Pet Safari, Nature (you need to call first),.....

Rainbow only have those $30 over one i remembered...
Saw those $8 one there but was told not for sale...

Thanks for the quick replies. Yeah, I meant the PH 4 and PH 7 buffer solutions. I sent my Eutech PH pen in for servicing and had my probe replaced. But the pen is still not working properly. Thought I should calibrate it again then see what happens.

For pH test pens...some only require pH 7.0 buffer solution to calibrate. Refer to your manual to see if you need both or just pH 7.0. C328 only has dennerle(branded) types I think...quite expensive as compared to what Chan at NA is selling(not dennerle).

you can get quite a big bottle at $15 from kings aquatic supplies . but I think they are out fo stock.

(supplier for the eutech ph pen. at jelan besar plaza I think).. search for it. I posted the address before.

You can check lab supplies. They may have them cheaper.

Appreciate all who replied. I managed to get hold of the buffer solutions from C328. The problem now is my Eutech pen... Still not working after sending it in for servicing. The Ph 7 buffer solution's reading was 15!! I am frankly getting a little frustrated by it all. Makes me wonder about the quality of products they make...

Anyway, I am giving them one more chance. Will be sending it in for servicing again next week. Argh
