About this material

What it is

The two most commonly paired reference materials in cosmetic-science screening work, supplied together in a sealed tray. Component certificates travel with the kit. Both compounds are light-sensitive and both ship in amber glass; the tray is opaque for the same reason.

Laboratory handling

Storage and material handling

  1. 01Check the kit seal before opening. A broken seal voids component traceability.
  2. 02Both components are light-sensitive. Keep the tray closed between withdrawals.
  3. 03Each vial retains its own component lot number.
  4. 04Dispose of unused material and rinsate according to your institution's chemical waste procedure.

Laboratory storage and material handling only. No dose, concentration, route, frequency or administration guidance is provided for this or any other item, for humans or animals.

Ordering

Purchase order went through without a phone call

Our accounts team needs an itemised quote with catalogue numbers before anything gets approved. The order sheet exported exactly that, including the lot numbers, so it went through procurement on the first pass. First time this year.
