General description

Aldrich® Negative Photoresist Kit I consists of materials for photolithography. The photoresist can be spin coated on the glass substrate for the formation of electrode arrays. The kit also provides masking and patterning on the glass surface.[1]

Application

Aldrich® Negative Photoresist Kit I has been used in the fabrication of microelectrodes by photolithography.[2] It can also be used to fabricate the droplet-based microfluidic device, microfluidic chips, glass optical waveguides, and integrated grating couplers.[3][4]

Questions

1–4 of 4 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/449/386/product-dating-information-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

  3. Can this negative photoresist be used directly on glass substrate for maskmaking followed by vaccum deposition of any metal with good adhereness .

    1 answer

    1. The photoresist in this product can be spin coated on the glass substrate. The kit also provides masking and patterning on the glass surface. However, there is no guarantee of good adherence to any metal. Please see the link below to review the kit technical bulletin:

  4. Please let me know if your Negative Photoresist 651796 is water free and send any information you have on use including the compounds other than the remover in the Kit 654892,

    1 answer

    1. Product 651796 refers to the kit component negative photoresist 1. The product is a solution of polyisoprene in a mixture of organic solvents. The reagent is not tested for water content on a batch-wise basis per the product specification. Water may exist, but only in very trace amounts.

      Please see the product datasheet located in the 'DOCUMENTATION' section for more information:
