White Labs Analytical Laboratory banks private cultures for customers for their future uses. White Labs will test, isolate, store and propagate your organism using our proprietary methods.
Production lead time is 21 to 30 days.

Every Private Strain is analyzed for microbial organisms. The fermentation of the original culture is monitored to ensure optimal performance and then cryogenically frozen. Requires a minimum order of 1.75L for Saccharomyces strains and a minimum order of 1L unconcentrated for wild yeast and bacteria. Please fill out the Yeast Banking Form when a sample is sent in.
