General description

Hellmanex III significantly reduces the surface tension of water. The removal of dirt particles is also assured by the good wetting action of a Hellmanex III aqueous solution, while its high emulsifying and dispersing capabilities prevent the redeposition of the loosened particles. Special surface-active substances facilitate the residue-free rinsing of the optical components once they have been cleaned.
Hellmanex III is filtered to 1 μm and is therefore virtually free of solid particles.

Application

The optimal dilution (usually 0.5 to 2 vol-%) depends on several factors, such as the hardness of the water, the degree and type of contamination, the temperature, etc. The use of demineralised water improves the cleaning characteristics.
An increase in temperature speeds up the cleaning process. However, at high temperatures it is necessary to avoid thermal shock. The cells should be pre-warmed before being submerged into hot cleaning solutions.
Hellmanex III, when diluted to its working concentration of 2%, is suitable for use with glass, quartz, sapphire, porcelain, ceramics, plastics, and ferrous metals. It can also be used, with some limitations, on metals that are sensitive to corrosion such as aluminium and other non-ferrous metals. In such cases, avoid prolonged application. In the case of materials not listed here, suitability tests should be carried out or enquiries directed to Hellma.
The concentrate can be stored in vessels made of stainless steel, PE, PP, PVC, FPM, or NBR.

The movement of a molecular motor protein along a cytoskeletal track requires communication between enzymatic, polymer-binding, and mechanical elements. Such communication is particularly complex and not well understood in the dynein motor, an ATPase that is comprised of a ring

Questions

1–2 of 2 Questions  

  1. 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

  2. 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.
