If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.

Will dispensing small quantities and resealing the container lead to air dissolving in the water? I intend to use 50ml-100ml for my experiments.
1 answer-
Opening a container that is not isolated from the atmosphere could results in ambient air dissolving in the water remaining inside the container. The rate of of air introduction would need to be monitored for a given set of conditions such as temperature, air exchange in the laboratory, and relative humidity.

How is shipping temperature determined? And how is it related to the product storage temperature?
1 answer-
Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf

How is this water purified? is it distilled?
1 answer-
The water purification process involves several steps:
• The water initially passes through a carbon exchange tank to remove organic compounds.
• It is then filtered using a 1μm PE cartridge filter to remove any remaining impurities.
• Inorganic compounds are eliminated through deionization tanks, ensuring high purity. The resistivity of the water is checked during this stage.
•The water undergoes sterilization using UV light to eliminate any microorganisms.
• Finally, the water is filtered through a 0.2μm cartridge filter, and the resulting HPLC grade water is packaged in glass bottles.
Note: This information provides an overview of the typical water purification process and may vary depending on specific applications or systems.Helpful?
