Vector Laboratories is closed for the President’s Day on Monday, February 19th. We will be back in the office on Tuesday, February 20th.
We will respond to emails upon our return. Have a wonderful day.


We are excited to announce that Fluoroprobes is now part of Vector Laboratories. Together, these companies combine dye synthesis expertise with conjugation capabilities, offering you a broad selection of products and custom manufacturing under one brand. 

Please note the following important account and ordering changes:

  • The complete Fluoroprobes product portfolio can be found at
  • Catalog numbers (product numbers) for Fluoroprobes have been updated:
    • Catalog numbers now have a “FP-” prefix. Example: 1300 has become catalog number FP-1300.
  • If you previously purchased products online from Fluoroprobes your account has been migrated to Vector Labs and you will need to reset your password at to place an online order.  (If you have already established a Vector account, no action is needed.)
  • Fluoroprobes products will be shipped in Vector Labs branded packaging. The box and the product label of a given product may appear different, but the contents are identical to what you have purchased previously from those companies. Vector’s shipping policies, which can be found at apply to all Fluoroprobes orders.

If you have any questions about this transition, please contact us at (Tel) 1-800-227-6666 ext 2 or via email [email protected].
