Lactose Broth is a liquid medium used for the detection and/or verification of the presence of Salmonella and other coliform organisms in water, foods, dairy, and pharmaceutical products. This medium is also used as a pre-enrichment in the analysis of food, milk products, and water for Salmonella. Lactose Broth also provides good growth characteristics for coliforms and fermentation is observed by gas bubbles present in an inverted fermentation tube. The concentration of media prepared for the test should be adjusted to accommodate a volume of sample greater than 10mL. Pancreatic Digest of Gelatin and Beef Extract provide nitrogenous, carbon and vitamin sources, being Lactose the fermentable carbohydrate. There is a choice of 3 sizes - 500g, 2kg, and 10kg.
PREPARATION: Mix 13 grams of the medium in one liter of purified water until evenly dispersed. Heat with repeated stirring and boil for one minute to dissolve completely. Distribute and autoclave at 121°C for 15 minutes.

Description not clear
So these are like exfoliation sponges - with a handle. I throughly they were cloths. I was surprised to see that when it arrived. Also, it said “assorted colors,” so I expected 3 different colors. We got 2 orange and 1 green. Also, I’m not sure how to keep these clean. We ran one through the wash, but it got soft and exfoliated less. But, it is like a sponge, so I don’t completely trust it to stay clean.
It works, though. I like the handle especially. It exfoliates nicely, without feeling like sand paper. A couple other brands I tried are either way too rough or too soft. This was just right. Can be used on the face. Just wish the description was clearer
