Buffers and media are the highest-volume materials in a biomanufacturing facility, and they are made by hand from a recipe. A weighing error, a wrong salt lot, or a buffer used past its hold time is a batch deviation, and nobody finds it until the batch is affected.

Solution prep sits between materials management and production and usually belongs to neither system, so no single record shows whether a given lot of buffer was made to recipe, checked, and still within hold when it was used. The recipe is a document, the prep is a form, and the expiry is a label.

Labbit runs preparation from a controlled recipe with balance-integrated check-weigh at every addition, releases the solution on pH and conductivity results, tracks filter integrity and hold time, and blocks expired solutions at the point of consumption in any batch.
