Many factors in materials impact foods and beverages. These range from safety issues, such as microbiological contamination, to texture issues, such as the smoothness of peanut butter.

Centrifuges used in blood banks and clinical settings are identical in function to those found in chemistry or biology labs, but methods and objectives may differ significantly depending on the end use.

Exosomes purification and analyses comprise a fast evolving research area; more than 70% of published research on exosomes has been done within the last six years.

Demand for trace metals analysis in the environmental laboratory is growing strongly due to stricter  environmental regulations. ICP has previously been the standard for metals analysis, but as demand for lower detection levels grows, labs are experiencing a significant transition to ICP-MS. This transition is placing increased emphasis on the sample preparation method.

Renewed interest in cell biology has created the need for techniques that efficiently disrupt cells’ outer membranes while sparing their contents.

Evaporators have for decades been staples in labs and industries performing chemistry, including labs in the chemical, environmental, materials, life science, and forensics industries. Key applications include sample concentration, solvent recycling, extractions, and separation of solvent mixtures.

When a scientist needs to concentrate a sample that’s in a volatile liquid—like acetone, acetonitrile, or methanol—a nitrogen evaporator can do the job. As a result, scientists use this technology in sample preparation in environmental, polymer science, quality control, and toxicology labs, plus others.

Some scientific and even industrial stirring applications seem no more complex than mixing milk in your coffee, but others demand much more control. In fact, some of the most demanding stirring applications might not even sound so complicated, including dissolving powdered milk in water, combining oil and water, incorporating pigments in a base coat of paint, and so on.

Microwave digestion in concentrated acid reliably eliminates sample matrix while rendering metals to species appropriate for analysis by inductively coupled plasma-mass spectrometry or atomic absorption.

Floor-standing ultracentrifuges and high-performance centrifuges are vital to many bioproduction  processes. Instruments are run in Good Manufacturing Practice (GMP) environments, and must support compliance with these regulations. Innovative features built into Optima XPN and Avanti JXN Series centrifuges support GMP compliance while eliminating much of the administrative work of other systems.

Genevac, a world leader in solvent removal technologies, has released a new 24-page guide ‘Introduction to Evaporation.’

Laboratory shakers come in a variety of configurations, including orbital, horizontal, incubator, tumbling, roller, overhead, rotator, and the subject of this article, rocking shakers. Within these categories, numerous
variables are possible: physical size and sample capacity, speed adjustment, shaking direction, sample pitch, direct temperature control through heating or cooling coils, and environment control through enclosures or use within incubators.
