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'.

Parasitology international, 62(5), 464-470 (2013-06-19)

Haemonchus contortus is a hemophilic nematode which infects sheep and causes anemia and death to lambs. Benzimidazole drugs are used to remove these parasites, but the phenomenon of resistance has arisen worldwide. A sensitive test to detect resistance before treatment

Embedding Ultrafine Metal Oxide Nanoparticles in Monolayered Metal-Organic Framework Nanosheets Enables Efficient Electrocatalytic Oxygen Evolution.

Wang Zhang et al.

ACS nano, 14(2), 1971-1981 (2020-01-31)

The development of highly efficient electrocatalysts to reduce overpotentials is vital for accelerating the sluggish oxygen evolution reaction (OER) processes. Herein, we demonstrate ultrathin heterogeneous nanosheets as a promising OER electrocatalyst, which are composed of ultrafine CoFeOx nanoparticles and a

A 2-(2-hydroxyphenyl)-1H-benzimidazole-manganese oxide hybrid as a promising structural model for the tyrosine 161/histidine 190-manganese cluster in photosystem II.

Dalton transactions (Cambridge, England : 2003), 42(4), 879-884 (2012-11-28)

In this communication, we report the synthesis, characterization, and electrochemistry of a 2-(2-hydroxyphenyl)-1H-benzimidazole-manganese oxide hybrid. Our results suggest that this compound is a promising model for the manganese cluster together with tyrosine-161 and histidine-190 in photosystem II of plants, algae
