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.

Application
- Bioflocculant produced by Bacillus velezensis and its potential application in brewery wastewater treatment: Diese Studie untersucht die Produktion eines Bio-Flockungsmittel durch Bacillus velezensis und bewertet seine Anwendung bei der Aufbereitung von Brauereiabwasser. Als Koagulationsmittel wurde Magnesiumsulfat eingesetzt, was die Ausflockung signifikant verbesserte (Agunbiade et al., 2022).
- Evaluation of the automated micro-solid phase extraction clean-up system for the analysis of pesticide residues in cereals by gas chromatography-Orbitrap mass spectrometry: In dieser Studie wird ein automatisiertes Festphasenmikroextraktionssystem für die Analyse auf Pestizidrückständen evaluiert. Zur Probenreinigung wurde Magnesiumsulfat verwendet, um die Effizienz und Genauigkeit der Extraktion zu verbessern (Hakme und Poulsen, 2021).
- Online supercritical fluid extraction and chromatography of biomarkers analysis in aqueous samples for in situ planetary application: In diesem Artikel wird eine Methode beschrieben, bei der die Extraktion mit überkritischen Fluiden und die Chromatographie für die Biomarker-Analyse kombiniert werden. Magnesiumsulfat spielte eine entscheidende Rolle im Extraktionsprozess und erleichterte die Trennung von Zielverbindungen (Abrahamsson et al., 2019).
- Bioremediation of oily hypersaline soil and water via potassium and magnesium amendment: Diese Studie untersucht die Bioremediation von öligen hypersalinen Umgebungen unter Verwendung von Magnesiumsulfat und Kalium, deren Zusatz die mikrobielle Aktivität und den Abbau von Kohlenwasserstoffen verbesserte (Al-Mailem et al., 2013).

How is shipping temperature determined? And how is it related to the product storage temperature?
1 Antwort-
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
