The solutions are intended for use as a certified reference material or calibration standard for the analysis of these elements in petroleum products or other organic matrices using inductively coupled plasma optical emission spectroscopy (ICP-OES), inductively coupled plasma mass spectrometry (ICP-MS), rotating disc electrode atomic emission spectroscopy (RDE-AES), flame or furnace atomic absorption spectroscopy (AA or GFAA), and other techniques for elemental analysis.

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.

Supplier: MERCK LIFE SCIENCE

The product range includes a full line of pre-poured 90 mm or 150 mm Petri dishes for a wide range of different applications, such as enumeration, isolation, detection and cultivation of bacteria as well as yeast and moulds. In order to choose the best packaging for each kind of use, both small packs of 20 plates and bulk packs of 100 plates are available for each kind of plate.

This solution is intended for use as a certified reference material (CRM) calibration standard, for ion chromatography (IC) and techniques using other modes of aqueous ion detection.

Supplier: Corning

PP, sterile or non sterile.

Supplier: Dr. Möller & Schmelz

These sterile ready-to-use media are filled in autoclavable and break-proof polycarbonate bottles (50 and 250 ml). The composition of the various types of media, comply with the formulations specified in the pertinent standards and regulations. Whereas the liquid media can be used immediately, the agar media first have to be remelted in a water bath at 90 to 100 °C. Once they have cooled down to around 50 °C you can pour agar plates in different sizes and thicknesses to meet your individual demands.

Supplier: Hach

Standard solution for accuracy checks in copper determinations.

Supplier: Dr. Möller & Schmelz

These sterile ready-to-use media are filled in autoclavable and break-proof glass tubes (20 ml). The composition of the various types of media, comply with the formulations specified in the pertinent standards and regulations. Whereas the liquid media can be used immediately, the agar media first have to be remelted in a water bath at 90 to 100 °C. Once they have cooled down to around 50 °C they can be poured as agar plates in different sizes and thicknesses to meet individual demands.

Supplier: Hach

Standard solution for chloride determination by argentometric burette titration.

Supplier: Merck

This medium conforms to the ALOA (agar Listeria acc. to Ottaviani and Agosti) medium, a selective medium for the isolation of Listeria monocytogenes in food (AFNOR-validated method). It also enables the testing, sampling and enumeration of Listeria monocytogenes and Listeria spp. in foodstuffs and other source materials. The rich base of the Chromocult® Listeria selective agar encourages excellent growth. The supplement of inhibitors stops most of the bacteria, yeast and fungi from growing. In contrast, Listeria is uninhibited in its growth, producing blue-green colonies; L. monocytogenes also form an opaque halo.

Supplier: Thermo Fisher Scientific

These standards are applicable for the determination of elements as dissolved elements in ground waters, surface waters, and drinking water, and total recoverable elements in these waters as well as wastewaters, sludges, and soils samples.
