The Reagents & Supplies module has some specific search features. 


You can find items with the original product barcode using a barcode reader. 

If the barcode reference is different for each lot, enter the barcode reference of the new lot on the lot’s reference field. 


Then you can find lots directly from the module’s keyword search field (you need to place the cursor in the keyword field then point the barcode reader to the product’s barcode).
