Per- and Polyfluoroalkyl Substances (PFAS), a family of more than 4,700 chemical molecules, are known for their non-stick and waterproof properties. These versatile compounds find their application in a variety of industries, including cosmetics, textiles, and automobiles. PFAS exhibit remarkable resistance to degradation, which has led to their pervasive distribution in the environment and consequent human exposure. The effects of such exposure are far-reaching, including adverse effects on fertility, developmental abnormalities, cholesterol levels, immune function, and an increased risk of certain cancers. In addition to their toxicological effects, PFAS have become a global concern as regulators and researchers strive to understand the extent of their impact and develop effective methods for detection and mitigation. This collection of articles brings together research on the contamination and effects of PFAS in air, soil, and water, shedding light on the complex challenges posed by these persistent substances in our environment. Overall, this collection of articles seeks to advance researchers' knowledge of the dynamics, effects, and detection of PFAS.

Cell or microbiological media and buffer preparation involve dissolving precise amounts of various salts, nutrients, and buffering agents in ultrapure water, followed by pH adjustment to suit specific organism requirements.

Sample preparation tools such as pipettes and lab water systems are vital for nucleic acid techniques (NAT), where high quality, contamination-free reagents and precise volume measurements are essential for reproducibility and accuracy.

Discover essential sample preparation tools for quality control, method development, and analytical excellence in chromatography, spectrometry and elemental analysis.

Bioassay techniques are pivotal in quantifying and characterizing the effects of substances on biological systems. Utilized extensively in biotherapeutics, diagnostics, and environmental sciences, these assays range from ELISA for protein and antibody detection to flow cytometry for cell health analysis. Bio-layer interferometry and cell-based assays further elucidate drug-receptor interactions.

Sartorius provides an extensive selection of lab essentials tailored for the initial stages of sample handling and preanalytical processes in quality assurance labs, catering to diverse characterization requirements. Our lineup includes accurate lab scales, high-purity water purification systems, superior filtering equipment, and comfortable pipettes and tips

The HPLC mobile phase impacts retention and selectivity of analytes. Therefore, mistakes in designing and preparing mobile phases will lead to considerable problems. This summary explains which areas of mobile phase preparation and design are most likely to result in method errors, ensuring you have the tools to recognize problems before they occur.

Ultrapure water is essential for accurate analyses because as analytical methods become more sensitive, they also become more vulnerable to interference. Maintaining consistently high water quality is crucial for ensuring reproducible results and avoiding the need for time-consuming repeat analyses:

Reliable and reproduceable liquid handling results depend crucially on the regular test and calibration of the instruments. The globally most accepted International Standardization Organization (ISO) standard that details requirements for producing and in-use control of piston-operated volumetric apparatus (POVA) is the ISO 8655. The aim of this white paper is to present the requirements for gravimetric calibration and testing of piston-operated volumetric apparatus (POVA) according to part 6 and part 7 of the ISO 8655 revised in 2022. This white paper presents the differences between calibration and testing according to chapters 6 and 7 , describes the testing method as well as testing environment, testing equipment and reporting requirements.

Bulb and graduated pipettes made of glass or plastic are common in the laboratory, especially when pipetting volumes greater than 1,000 µL. One example of graduated pipettes are serological pipettes. Plastic (disposable) serological pipettes are widely used in cell culture applications. There are multiple reasons to replace serological pipettes with Sartorius pipettes. Discover the three main reasons to switch to a Sartorius pipette.

ISO 8655:2022 contains updated requirements for producing and in-use control of piston-operated volumetric apparatus (POVA), replacing the 1st edition from 2002. ISO 8655:2022 consists of nine parts in total. Here, we describe the main points about Part 2: Pipette

Pipettes and pipette accessories are staples in most laboratory environments, from biochemistry to pharmaceuticals to beverage quality control. Because different assays have different needs in terms of equipment and technique, it is important to assess the particular set of needs required in your lab. Key requirements for most modern-day applications include: Accuracy, minimizing human errors, speed, easy-to-clean-instruments, precision, ability to decontaminate and avoiding contamination.

In this guide, Sartorius explores some factors to consider when choosing a manual or electronic pipette for microbiological analyses. Requirements for liquid handling in a microbiology lab might be different from other analytical laboratories. Here are some points to consider before committing to purchasing a pipette
