Ready-to-use, pre-prepared growth media in flasks

Sigma-Aldrich now offers flasks containing different types of popular growth media, both broths and agars, in a convenient, readyto- use form. The new product line saves an enormous amount of time in both preparation and sterilisation. They are also much safer to use since they require no autoclaving. To use, simply melt the flasks of solid media in a microwave without losing or changing any promotional growth characteristics. Flasks of liquid media can be used without any further steps. The flasks and metallic caps are completely microwave safe (Figure 1).

Ready-to-use, pre-prepared agar plates in blister packs

As a further way to help microbiologists save time, we now offer pre-cast, readyto- use agar plates. The formulations follow pharmacopeial and ISO regulations for testing the microbial content of liquid samples, like water and beverages, using the membrane filtration technique. The plates have a diameter of 55 mm and contain 10 mL of medium for accurate results after longer incubation times. Each box contains 30 plates in five blister packs (Figure 2).
