What is “Search by Lot Number”?

Prismatic identifies most of its products by printing the following information on them:

  • Product Description (alphanumeric characters) provides an easy method for the user to identify the product.
  • Lot Number is the serial number printed after the “#” and is assigned to a batch of products. It identifies the product and important traceability information of products in that batch.
  • Wherever space permits, “Prismatic” or “PEPL” is also printed on the product.

 The Lot Number Search option on our Homepage allows you to find out the product code and description from the Lot Number provided. You may use this information while requesting a quote or sample. Lot Numbers of very small parts may be obtained from the labels affixed on the packing boxes.


Why is the “Search by Lot Number” returning an error message or not identifying the product?

The lot number provided by you does not exist, or is a custom part as clarified below.

Prismatic has many products developed to customer's specifications. We do not share details of such custom products, unless permitted by the customer. We will similarly safeguard your interests on all products developed against your specifications.
