Acetonitrile, LiChrosolv®, Isocratic Grade for liquid chromatography, Supelco®

Supplier: Merck

With their high degree of UV transmittance, low particle count, low acidity and alkalinity and low evaporation residue level, LiChrosolv® solvents are ideal for reproducible separations. Since separations are normally carried out under gradient conditions in analytical HPLC, we offer solvents in "gradient grade" as well as "isocratic grade". This enables to minimize the gradient effect of the solvent involved.

Dehydrated culture media, TOS-propionate agar (base)

Supplier: Merck

In combination with the selective supplement Lithium-Mupirocin (MUP) the TOS Propionate agar allows the direct detection of viable bifidobacteria in starter cultures and various milk products like fermented and unfermented milk, milk powder and baby food. The growth of other lactic acid bacteria is very much inhibited so that a confirmation of presumptive bifodobacteria is in most cases not necessary.
