Process optimization made easy: design of experiments with multi-bioreactor system BIOSTAT® Qplus

The BIOSTAT® Qplus with up to 12 culture vessels represents the basis for a professional and time-saving process optimization.

22-10-2013

Design of experiments (DoE) is one of the most important techniques for systematic planning, execution and statistical evaluation of experiments. Although a DoE investigation is executable in one bioreactor, multi-bioreactor systems designed for parallel operation provide the optimal basis ...

VACUU•LAN® Vacuum Local Area Networks

The state-of-the-art alternative for central vacuum systems

08-04-2011

In modern chemical and pharmaceutical lab buildings vacuum supply has become a standard for each work station, just as water or gas supply. Therefore vacuum supply solutions are considered at earliest stage for new laboratory buildings and are fully integrated in the planning and layouting ...

Characterizing Biotherapeutics with HPLC

Smart Solutions for large Molecules

24-11-2010

As demonstrated here, there are a broad range of HPLC applications used in development, production, validation and release of protein therapeutics for human use. Some of the applications mentioned above are mandatory when submitting a new biopharmaceutical to approval at the regulatory agencies. ...

Analysis of water soluble polymers using linear size exclusion HPLC columns and a semi-micro SEC system

16-11-2010

One of the most widely used water-soluble polymers is Polyvinylpyrrolidone (PVP). For more than 70 years it is applied in a variety of applications in medicine, pharmacy, cosmetics and industrial production. PVP binds to polar molecules exceptionally well. It supports the solubility of tablets in ...

Field-Flow Fractionation - The Universal Separation Principle for Particle and Macromolecule Characterization

22-09-2010

High molecular weight polymers, bio molecules or particles in a range of a few nanometers up to several microns are more and more important in science and technology. Many applications are based on the specific properties of these materials. For this reason, an exact knowledge of the molar mass ...

Size and element specific determination of Ag nanoparticles in consumer spray products using asymmetric flow field flow fractionation (AF4) coupled to ICPMS

10-09-2010

The use of nanoparticles in consumer products shows a tremendous increase over the past years. A study of the Woodrow Wilson International Centre for Scholars reported that between 2005 and today the number of products based on nanoparticles increased almost twentyfold from 54 to 1015. As active ...

Absolute Molar Mass Characterisation

27-11-2009

Multi-angle light scattering coupled to SEC or other fractionation methods can provide an absolute means for measuring the molar mass, size and distribution of proteins, polymers and particles of all sorts. Wyatt Technology's MALS also enables the elucidation of additional data such as branching, ...

35 years' experience in "black gold"

High-quality bitumen for worldwide road construction provided by Viennese engineering company Pörner based on Biturox® technology

27-04-2009

There is a paradoxical consequence of the financial crisis: To produce bitumen is more attractive than ever. In the last six months prices for crude oil and, in particular, the consumption of heavy, sulfur-containing marine Diesel fuel (bunker oils) have dropped, while at the same time the need ...

Sensible and self-monitoring

Online process for soft water control

27-11-2007

For the generation of soft water are mostly used ion exchanging devices with generation of sodium chloride since the beginning of the Sixties. The generated soft water quality and soft water quantity are depending thereby on the static and dynamic characteristics of the softening plant in ...
