Dried Yeast (Active) – LR Grade, 100g

Dried Yeast (Active), also described as fermentative yeast, is supplied in a 100g pack and produced to Laboratory Reagent (LR) grade. This biologically active material is widely used in educational science settings, particularly for demonstrating fermentation and respiration processes in a safe and engaging way.

With no assigned UN number and no specific CAS number, active dried yeast is not classified as hazardous for transport when used appropriately. It reactivates quickly in warm water and sugar solutions, making it ideal for repeated classroom experiments and clear, observable results.

Easy to store, measure, and prepare, this dried yeast is well suited to routine school laboratory use and supports both biology and chemistry teaching across multiple key stages.
