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.

Freeze dryers find use in a variety of research and manufacturing environments and are commonly used for material storage, food and pharmaceutical processing, as well as for less common applications such as taxidermy and document recovery. With a wide variety of options available, there is much to consider when purchasing a new freeze dryer.

For the past 40 years scientists from all over the world have trusted Labconco Freeze Dry Systems to lyophilize and protect their assets. With sizes ranging from 1L to 18L and over 17 drying accessories available, FreeZone Freeze Dry Systems can be customized to lyophilize almost any type or size of sample. Don’t settle for just any lyophilizer, order a freeze dryer that you have selected specifically for your samples.

The aim to achieve ultrafine and nano-sized materials is becoming of great importance as effort in nanotechnology is a key driver in the development of innovative products.  To attain particles in this region, many techniques can be used such as synthesizing such materials as well as high energy milling. 

Nimbus analytical and precision balances from Adam Equipment feature a compact footprint and easy operation. With readabilities from 0.1mg to 0.1g, capacities from 80g to 22kg, plus USB and RS-232 connections, the Nimbus provides a streamlined weighing experience for discerning professionals worldwide.

Abstract: Persistent organic pollutants (POPs) can cause long term damage to the environment. Two classes of organic molecules have come to the attention of regulators and water treatment authorities in recent years; iodinated X-Ray contrast media (XCM) and artificial sweeteners (AS). These molecules, by design, have a high degree of stability. Aware of the increased abundance of these molecules in waste water, the IWB Water Laboratory set out to develop a robust, simple method to analyse levels of these molecules in water from the river Rhine, ground water and drinking water.
