FAQs
1. What is the shelf life of this pH 4.01 buffer solution when unopened?
The unopened solution remains stable for 24 months from the date of manufacture when stored at room temperature in its original packaging.
2. Can this buffer be used with glass and epoxy-body pH electrodes?
Yes, the solution is compatible with both glass and epoxy-body pH electrodes, provided the electrodes are properly conditioned before use.
3. Is this buffer solution autoclavable for sterile applications?
No, autoclaving is not recommended as it may alter the pH value and compromise the solution’s integrity.
4. How should I dispose of expired or unused buffer solution?
Dispose of according to local chemical waste regulations; neutralize if required before disposal in designated laboratory waste streams.
5. Does this buffer contain any preservatives or stabilizers?
The Specpure® formulation is preservative-free to maintain purity, but the sealed packaging prevents microbial contamination during storage.
