General description

EMD Millipore bietet EMPARTA Lösungsmittel für Routineaufgaben in analytischen Laboratorien an. EMPARTA Lösungsmittel haben zwar weniger Testparameter als EMSURE, sind aber dennoch von hoher Qualität. EMPARTA Lösungsmittel bieten absolute ACS-Konformität, wodurch sie sich ideal für eine Vielzahl von analytischen Anwendungen eignen.
Wir verpflichten uns, Ihnen umweltfreundlichere Alternativprodukte anzubieten, die mit einem oder mehreren der „12 Prinzipien der Grünen Chemie“ im Einklang stehen. Dieses Produkt ist bioerneuerbar und eine Alternative zu petrochemischen Lösungsmitteln. Ethanol ist ein unter ökologischen Gesichtspunkten vorzuziehendes Lösungsmittel und steht deshalb im Einklang mit den Prinzipien „Sicherere Lösungsmittel und Hilfsmittel“ sowie „Nutzung nachwachsender Rohstoffe“. Weitere Informationen finden Sie hier
EMPARTA solvents are designed for routine chemical synthesis, drying, purification, and critical labware cleaning in quality control environments. Engineered for precision, they deliver consistently reproducible results essential for rigorous validation and documentation.

Exceptional Quality Standards: These solvents meet or exceed ACS specifications, providing assurance of high quality that is crucial for accurate testing and analysis in quality control.

Consistent Reproducibility: Designed for precision, the solvents ensure that results can be reliably reproduced, which is vital for maintaining compliance and integrity in quality control processes.

Versatile Applications: Suitable for a variety of QC tasks, including analytical testing, method validation, and testing USP/NF monographs, these solvents support a comprehensive approach to quality assurance in laboratory settings.

Application

Ethyl alcohol, pure can be used as a solvent in many cleaning and research applications including extraction and preparation of samples:
  • To prepare a homogeneous dispersion of ZnO-Ts powder for effective separation by differential centrifugation.
  • In the extraction of capsaicinoids in pepper sample.
  • To purify and fractionate corn-stover lignin, enhancing molecular weight for improved carbon fiber production.

Questions

1–2 of 2 Questions  
  1. How can I determine the shelf life / expiration / retest date of this product?

    1 answer
    1. 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.
      For more information, please refer to the Product Dating Information document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/418/501/product-dating-information-06-25-mk.pdf

  2. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 answer
    1. 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
