How to Find a Lot/Batch Number for COA

Lot and Batch Numbers can be found on a product's label following the words 'Lot' or 'Batch'.

Aldrich Products

For a lot number such as TO09019TO, enter it as 09019TO (without the first two letters 'TO').
For a lot number with a filling-code such as 05427ES-021, enter it as 05427ES (without the filling-code '-021').
For a lot number with a filling-code such as STBB0728K9, enter it as STBB0728 without the filling-code 'K9'.

Not Finding What You Are Looking For?

In some cases, a COA may not be available online. If your search was unable to find the COA you can request one.

Precision and reproducibility of temperature response of a thermo-responsive membrane embedded by binary liquid crystals for drug delivery.

S Y Lin et al.

Journal of controlled release : official journal of the Controlled Release Society, 73(2-3), 293-301 (2001-08-23)

A thermo-responsive membrane embedding with the binary mixture of 36% cholesteryl oleyl carbonate (COC) and 64% cholesteryl nonanoate (CN) was successfully developed to achieve a rate-controlled and time-controlled drug release in response to the skin temperature (i.e., 32 degrees C)

Plasmon-Exciton Interactions Probed Using Spatial Coentrapment of Nanoparticles by Topological Singularities.

Paul J Ackerman et al.

ACS nano, 9(12), 12392-12400 (2015-11-17)

We study plasmon-exciton interaction by using topological singularities to spatially confine, selectively deliver, cotrap and optically probe colloidal semiconductor and plasmonic nanoparticles. The interaction is monitored in a single quantum system in the bulk of a liquid crystal medium where

Three-dimensional crystals of adaptive knots.

Jung-Shen B Tai et al.

Science (New York, N.Y.), 365(6460), 1449-1453 (2019-10-12)

Starting with Gauss and Kelvin, knots in fields were postulated to behave like particles, but experimentally they were found only as transient features or required complex boundary conditions to exist and could not self-assemble into three-dimensional crystals. We introduce energetically

Thermochromic Fibers via Electrospinning.

Jimmy Nguyen et al.

Polymers, 12(4) (2020-04-10)

Cholesteryl ester liquid crystals exhibit thermochromic properties related to the existence of a twisted nematic phase. We formulate ternary mixtures of cholesteryl benzoate (CB), cholesteryl pelargonate (CP), and cholesteryl oleyl carbonate (COC) to achieve thermochromic behavior. We aim to achieve
