  1. Which document(s) contains shelf-life or expiration date information for a given product?

    If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.

  2. How do I get lot-specific information or a Certificate of Analysis?

    The lot specific COA document can be found by entering the lot number above under the "Documents" section.

  3. What is the molarity of Phenol solution, Product P4557?

    The Molarity is ~10.6.  The density of the phenol is 1.05g/ml, and the molecular weight is 94.11.

  4. I see that there are two layers in the bottle Phenol solution, Product P4557. Which layer do I use?

    The top phase is Tris buffer, so use the lower/bottom phase.

  5. What do I do to equilibrate the Phenol solution, Product P4557, to around pH 8?

    This phenol solution (Product No. P4557) includes a separate bottle of equilibration buffer (Product No. B5658) to adjust the phenol phase to pH 7.9±0.2. After addition of the buffer to the phenol, it may take about 6 hours (mixture can be kept at 2-8 °C) until the bottom phase (phenol) becomes clear. Some of the haziness in the phenol phase may be due to some air bubbles caused by mixing by inversion. There could be a hazy interface between the phenol and aqueous phase which remains after the separation.  The entire contents of the bottle of the buffer should be added to the phenol. If buffering less than the complete bottle, use at a ratio of 6.5 mL buffer to 100 mL phenol. For 10 mL of phenol, use 650 μL of buffer. For 1 mL of phenol, use 65 μL of buffer.

  6. What is the final pH of Phenol solution, Product P4557, after adding the buffer?

    The pH is typically 8.0; the specifications state a range of 7.7-8.1.
