Product news

Viscotek, the leader in advanced detectors, software and systems for characterisation of natural and synthetic polymers, copolymers, proteins and nanoparticles will be exhibiting its latest range of instrumentation at Pittcon 2006 in Orlando, Florida.

Visitors to booth 2138 will have the chance see and discuss the state-of-the-art Dynamic Light Scattering (DLS) instrument for biomolecular characterisation - the Model 802 DLS. Offering superior sensitivity, resolution and accuracy, born out of Viscotek's exclusive single mode fibre (SMF) technology, the Model 802 DLS delivers leading edge results for applications including screening protein constructs for crystallisation, characterisation of colloidal and nanoparticulate drug delivery systems, protein conformation analysis and measuring the stability and size of lipids and conjugates. Premiering at the show will be the new Model 802 DLS OmniSize 2.0 software that includes a range of new features including a unique regularisation algorithm.

Also on display will be the company's market leading multi-detector GPC/SEC systems including the Triple Detector Array (TDA), the GPCmax and the latest revision of OmniSEC software. Viscotek triple detection systems, which employ a concentration detector, viscometer and light scattering detector operating in concert, are today the defacto standard for the characterisation of natural and synthetic polymers and proteins in the petrochemical, specialty chemical, elastomers, adhesives, coatings, food, agricultural, academic, pharmaceutical and biotechnology markets.

For scientists looking to characterise and quantitate polymers in the production environment Viscotek will be showing its popular FIPA system and a new version of its Model 501 Dilute Solution Viscometer (DSV). To automate acquisition and processing of data Viscotek has consulted with industry users to produce new Automated Relative Viscometry software. Based upon Viscotek's patented Y501 viscometer design the Y501 ARV system measures solvent and sample viscosity simultaneously, avoiding errors due to temperature fluctuations and solvent variations. The system provides faster analysis, greater precision and less solvent exposure when compared to the traditional Ubbelohde or Cannon-Fenske glass tube viscometers that it replaces.

Founded in 1985, Viscotek's innovative products and technologies are backed in Europe, North America and Asia by superior technical service and analytical support.

Protein CrystallographyProtein crystallization is the process of crystallizing purified proteins for 3D structure analysis by x-ray crystallography. The main methods of protein crystallization include sitting drop, hanging drop and microbatch. It is important to control parameters such as pH, temperature and concentration. Following crystallization, detectors and software are used for data collection and analysis.NanotechnologyNanotechnology, or nanotech, is an engineering technique using molecular scale functional systems. Applications of nanotechnology include medicine and medical devices, electronics, air and water purification, food science and energy production.ViscometersViscometers are used to measure the viscosity of a fluid. Types of viscometer include rotational, vibrational and falling piston viscometers. Options for viscometers include modular, portable, benchtop and temperature compensation and density measurement features.Particle CharacterizationParticle characterization instruments are used to determine particle size distribution, shape, surface area, zeta potential, density and porosity of particles and materials. Multiple tecchniques are available for determining particle size, shape and count including dynamic light scattering (DLS), laser diffraction, electrozone (Coulter technique), imaging particle analysis and single particle optical sensing. Determine the density of your material with a gas pycnometer or examine its surface area and porosity with gas adsorption analyzers and mercury porosimeters.
