Kieselguhr is a natural diatomaceous earth that can be used for the separation of polar or moderately polar compounds. For the mixed layer plates a combination of classical silica gel 60 and kieselguhr is used, providing favorable properties for certain applications such as separations of inorganic ions, herbicides or steroids.

The Milli-Q® SR 240 water purification system delivers pure reverse osmosis (RO) water to a mobile SQ Switch 3,5 L tank. This tank is easily transferred to the Milli-Q® SQ 200 Purification System to produce fresh ultrapure water anywhere in the lab. Thanks to the mobile SQ Switch tank, this water system adapts to any lab configuration: the RO water production unit is placed next to a potable water source, while unlimited ultrapure dispensing modules can be positioned anywhere in the lab or building with an electrical outlet. This allows for a flexible installation that can be easily adapted and scaled according to changing lab requirements.

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 minimise the gradient effect of the solvent involved.

In hematoxylin-eosin staining (H&E), the most widely used histological staining technique, nuclear staining is achieved using ready-to-use staining solutions, such as Mayer’s hemalum solution or Hematoxylin solution modified according to Gill III. These solutions do not need to be filtrated prior use and the dye is oxidized in a controlled manner, which renders the results robust and allows a brilliant differentiation of the stained structures. Counterstaining of i.e. for proteins, collagen, keratin, intercellular substances. can be performed with alcoholic or aqueous Eosin Y solution 0.5 %. It is registered as IVD and CE certified product and can be used for clinical diagnostics.

Ascentis® Express C8 high-speed, high-performance liquid chromatography columns are based on the highly efficient Fused-Core® particle design.

Supplier: Merck

TLC plates, that feature a smooth and extremely dense plate coating, ensuring narrow bands and maximum separation efficiency with the lowest background noise. Flexible plastic sheets can easily be cut to match individual separation requirements.

Supplier: Merck

MQuant® (MQ) test strips can be considered as a mobile laboratory on a few square millimeters of plastic strip. As a screening method they provide the user with a rapid overview of the situation, which helps in making the choice of what, and perhaps if, further analysis is required, thereby leading to potentially substantial savings in time and analytical resources. The strip is a biologically-degradable polyester foil and the low reagent content, in the reaction zones, assists problem-free waste disposal.

PLC (Preparative Layer Chromatography) plates are based on the same proven Merck silica-binder technology as analytical TLC plates. Plates are available with layers of unmodified silica gel or RP-18 modified silica gel in several layer thicknesses, ranging from 500 to 2000 µm, with or without fluorescent indicator.

The LuxPlate® range of high fluorescence TLC plates contains an increased amount of fluorescent dye making it easier to identify small amounts of isolated material. Furthermore, the amount of binder added is elevated, resulting in a significantly brighter TLC plate with an even more stable and robust surface.

Merck TLC aluminium oxide plates use neutral or basic aluminium oxide of 60 or 150 Å pore size with or without fluorescent indicator to suit different application needs. Under aqueous conditions, basic compounds can be best separated on basic aluminium oxide plates, while neutral compounds are best separated on neutral plates.
