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.

General description
Methode: kolorimetrisch mit Teststreifen 10 - 40 - 80 - 180 - 400 mg/L (SO32-), MQuant®
Die MQuant® Sulfitteststreifen sind zur Lebensmittelanalyse geeignet, insbesondere zur Prüfung von Wein und Fruchtsäften, schwefelhaltigen Lebensmitteln (z. B. frischem und getrocknetem Obst), Fisch, Schalentieren, Krebstieren und Hackfleischprodukten. Die Sulfitionen reagieren mit einem Gemisch aus Kaliumhexacyanoferrat(II), Zinksulfat und Natriumnitroprussid und bilden eine rote Verbindung. Die Sulfitkonzentration wird durch Sichtvergleich der Reaktionszone des Teststreifens mit den Feldern einer Farbskala semiquantitativ gemessen. Die Teststreifen eignen sich ideal für die kostengünstige und schnelle Voruntersuchung einer Probe, um die Sulfitkonzentration und den potenziellen Verdünnungsfaktor zu bestimmen, bevor eine quantitative Methode wie der Reflectoquant® oder Spectroquant® Sulfittest angewandt wird.
Design für Nachhaltigkeitsvorteile:
Wir setzen uns für Umweltschutz und Nachhaltigkeit ein und suchen ständig nach Möglichkeiten, um die Produkte in unserem Portfolio zu verbessern. Kürzlich haben wir untersucht, wie wir die Umweltauswirkungen der Produktreihe der MQuant®-Teststreifen minimieren können, ohne die Produktleistung zu beeinträchtigen.
Dieses Produkt hat von folgenden Änderungen profitiert:
- Verringerung der Teststreifenbreite
- Recyceltes Aluminiumröhrchen
- Digitale Bedienanleitung

We produce canned food, and sometimes our products contain Mata-Bi-sulfite as preservative. I would like to to verify that products produced after the mentioned allergenic products, contain less than 10 PPM sulfite. Will these strips do the job?
1 answer-
These test strips have a measuring range of 10 - 400 mg/L or 10 - 400 ppm Sulfite. This product would not be suitable for concentration of less than 10 ppm. Please see the links below to review more sensitive tests available:

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

For wine, How It work? We buy for wine, but we dont find the instructions
1 answer-
Sulfite ions react with a mixture of potassium hexacyanoferrate(II), zinc sulfate, and sodium nitroprusside to form a red compound. The sulfite concentration is measured semiquantitatively by visual comparison of the reaction zone of the test strip with the fields of a color scale. Please see the link below to review the product instructions:
