Hi Ali.  They have flat probes for this.  You can find them at any of your pH meter suppliers or large distribution companies.

Subject: [PMFLIST] pH of Agar Medium

Hi Members;



I have a question regarding culture media pH, in USP (62) states that the pH of different media, if necessary, adjust before sterilization and after sterilization it is within specific medium pH range at 25 C... My question here is, how we can measure the pH of agar medium at 25 C whereas it is solidified below 45 C... How we can use electrode to measure the pH of agar medium at 25 C...



Kindly guide me in this matter...



Thanks...
