Ready-to-use 2mL ampoule Wallerstein Broth (WL) is a liquid culture growth media that can save time and money by shortening prep time and minimizing possible contamination. The 2mL ampoules contain enough media to saturate a standard absorbent pad in a petri dish.
WL Nutrient Broth is for the cultivation and enumeration of yeast and WL Differential Broth is for determination of bacterial count. Use of the medium at pH 5.5 and incubation at 25°C will give reliable counts for brewer’s yeast. Adjustment of the pH to 6.5 and incubation at 30°C allows for the selective growth of baker’s and distiller’s yeast.

Don’t buy for restaurant industry
Size: 10.5, Color: Black, Size: 10.5, Color: Black
Good looking shoes, fairly comfortable and good value based on the description shared, so I don’t feel it’s fair to rate them lower than 4 stars. I had high hopes for them based on previous reviews from others saying they wore them in the food and beverage industry that mentioned their quality and durability, however I strongly recommend looking elsewhere if you do. I purchased these to wear working in a full service upscale restaurant and in less than two months have managed to have torn the material on the middle exterior section and the bottoms of the shoes are already completely worn down. Good design, but the durability needs to be improved if they’re to hold up for that industry.

DO NOT BUY (lasted less than 7 months)
Size: 11, Color: Black, Size: 11, Color: Black
I bought these for work as a bartender in August of 2025. By December, the tops were scuffed, frayed, and peeling beyond repair, and by February, the soles were coming off. I’ve never had a pair of shoes with such low quality.
