Merck: a leading brand in laboratory science and technology

The history of Merck

Merck traces its origins to 1668, when Friedrich Jacob Merck took over the Engel pharmacy in Darmstadt, Germany. From a traditional pharmacy it grew step by step into a science and technology group operating worldwide. Across more than 350 years, Merck has maintained a culture of innovation, with research and applied science directed at challenges in healthcare, life science and materials technology.

The company works in three main areas today:

• Life Science
• Healthcare
• Electronics — materials and electronic technology

Of these, Life Science supplies many of the products and solutions essential to research, analysis, testing, drug development and biomanufacturing.

Merck Life Science in the laboratory

Merck Life Science offers an ecosystem of products and services covering the whole research and production process, from sample preparation and chemical analysis through to drug development and pharmaceutical manufacturing. The catalogue serves fields including:

• Chemical analysis and quality testing
• Pharmaceutical and biotechnology research
• Food and beverage testing
• Environmental and water analysis
• University and institutional research
• Chemical, pharmaceutical and cosmetic manufacturing
• Microbiology, molecular biology and cell culture
• Quality control in industrial production

The breadth of the catalogue lets customers select a solution matched to a particular test method, analytical standard or quality-control requirement.

Key Merck product groups

Laboratory chemicals

Merck supplies a wide range of chemicals for research, analysis and production, including inorganic acids, bases and salts; organic solvents; analytical reagents; synthesis chemicals; standard solutions; indicators and specialised reagents; and chemicals for biology and microbiology. Products are available in a range of purity grades, so a laboratory can choose the right chemical for the intended purpose.

Analytical solvents

Merck solvents are used widely in modern analytical techniques including HPLC, UHPLC, LC-MS, GC, spectroscopy, residue analysis, and sample preparation and extraction. The specialised solvent lines are tightly controlled for purity, water content, evaporation residue and any impurity capable of affecting an analytical result.

Reference standards and standard solutions

Reference standards are essential to instrument calibration, calibration-curve construction and verification of method accuracy. Merck offers standards and standard solutions for ion analysis, titration, pH and conductivity measurement, metals analysis, chromatography, food testing, pharmaceutical testing, and environmental monitoring. Depending on the product, standards may be supplied with quality documentation and traceability information for testing purposes.

Microbiology products

In microbiology, Merck supplies products for the detection, isolation and enumeration of microorganisms, including culture media, ready-prepared media, contact plates, microbiological membrane filters, rapid test kits, sterility-testing products, and sampling and environmental-monitoring devices. These are applied in pharmaceuticals, food, beverages, cosmetics, clean water and many other manufacturing sectors.

Filtration and purification consumables

Merck offers filtration and purification solutions for the laboratory and for production, including membranes, syringe filters, vacuum filtration units, ultrafiltration devices, microbiological filtration systems, protein and nucleic acid purification products, and sample handling and preparation solutions. Choosing the right membrane material and pore size limits sample loss, reduces impurities and improves the reliability of results.

Purified laboratory water

Water is among the most heavily used materials in any laboratory, and water of unsuitable quality can compromise reagents, instruments and results. Merck develops purified and ultrapure water solutions for preparing solutions and reagents, for HPLC and LC-MS, for molecular biology, for cell culture, for trace analysis, and for cleaning laboratory glassware.

Why laboratories choose Merck

Consistent product quality

Merck products are controlled against quality criteria appropriate to each application — an important factor in reducing error and improving the repeatability of test results.

A broad catalogue

From basic chemicals, chromatography solvents and reference standards through to culture media and filtration consumables, Merck provides many solutions within a single product ecosystem. This makes it easier for a laboratory to standardise its consumables and to simplify selection and supplier management.

Clear technical information

Many Merck products come with supporting documentation, including the certificate of analysis (COA), the safety data sheet (SDS), product specifications, storage instructions, product code and lot number, and chemical safety warnings. These documents support quality assessment, chemical management and the requirements of a quality-management system.

Suited to a range of analytical methods

Merck develops dedicated product lines for individual applications, from routine analysis to techniques requiring high sensitivity. Users can select the appropriate product grade rather than applying one chemical to every method.

Support for research and production

Beyond supplying chemicals, Merck builds solutions covering each stage of the work, from early research and process development through to quality control and manufacturing.

Merck products in practice

Pharmaceuticals and biotechnology

Merck chemicals, solvents, filtration consumables and microbiology products are used in active-substance research, formulation development, raw-material testing, quality control and production-environment monitoring.

Food and beverage

Testing laboratories use Merck products to analyse composition, additives, metals, microorganisms and other food-safety parameters.

Environment and water treatment

Merck reagents, standard solutions and analytical products support the determination of physicochemical parameters in drinking water, wastewater and environmental samples.

Education and research

Universities, research institutes and science centres use Merck chemicals in teaching, practical work, research and method development.

Industrial manufacturing

Merck products are used to check incoming materials, monitor production processes and assess finished-product quality across many industries.

Choosing the right Merck product

To select the correct product, define clearly: the chemical or active substance required; the CAS number; the product or catalogue code; the purity grade; the analytical method; the pack size; the storage conditions; the COA and SDS requirements; and the standard or procedure being applied.

For methods such as HPLC, GC or LC-MS, choose the solvent line designed for that technique. Going by the chemical name alone, without checking the product grade, can affect both the instrument and the analytical result.
