Bio-Based Ethanol
Instead of synthetic ethanol, we use bioethanol produced from grain or sugar cane. High quality, affordability, and ready availability make our bioethanol an obvious choice for a sustainable future.

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 minimises the gradient effect of the solvent involved.

Supplier: Merck

Potassium iodine paper is used for the determination of oxidising agents.

Supplier: Merck

Test kits for quick, semi-quantitative analysis in situ, without the expense of transporting samples to the laboratory. Simple step by step illustrated instructions mean the kits can be used without special chemical training.

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.

Supplier: Merck

For calibration of pH meters.

Supplier: Merck

EMSURE® grade solvents are suitable for a broad spectrum of classical lab applications, and are frequently used in regulated and highly demanding lab applications. The EMSURE® range are in compliance with the ACS, with the reagent part of the European Pharmacopoeia (Reag. Ph Eur) and also with the ISO standards.

Supplier: Merck

1,4-Dinitrobenzene for synthesis, Sigma-Aldrich®

Supplier: Merck

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.

Supplier: Merck

Glyoxalbis(2-hydroxyanil), GR for analysis, Supelco®

Supplier: Merck

Chromolith® Prep monolithic stationary phases are new ultrapure silica phases which gain their special properties from a bimodal pore structure. This structure is a property of the new 'Sol-Gel' technology and consists of macropores and mesopores. The mesopores with an average diameter of 12 nm, form the fine porous structure of the column interior and create a very large surface area on which adsorption of the target compounds occurs.
