A glovebox (or glove box) is a sealed container that is designed to allow one to manipulate objects where a separate atmosphere is desired. Built into the sides of the glovebox are gloves arranged in such a way that the user can place their hands into the gloves and perform tasks inside the box without breaking containment. Part or all of the box is usually transparent to allow the user to see what is being manipulated.It allows manipulation of substances that must be contained within a very high purity inert atmosphere, such as argon or nitrogen. It is also possible to use a glovebox for manipulation of items in a vacuum chamber.
Thermogravimetric Analysis (TGA) measures weight changes in a material as a function of temperature (or time) under a controlled atmosphere. Its principal uses include measurement of a material's thermal stability and composition. Thermogravimetric Analysis instruments are routinely used in all phases of research, quality control and production operations.
Differential Scanning Calorimeters (DSC) measures temperatures and heat flows associated with thermal transitions in a material. Common usage includes investigation, selection, comparison and end-use performance evaluation of materials in research, quality control and production applications. Properties, measured by DSC include glass transitions, "cold" crystallization, phase changes, melting, crystallization, product stability, cure / cure kinetics, and oxidative stability.
Dynamic Mechanical Analysis measures the mechanical properties of materials as a function of time, temperature, and frequency. In addition to basic material properties, DMA also quantifies finished part characteristics, reflecting the important contribution that processing has on end-use performance. DMA is commonly used to measure glass transition temperatures and secondary transitions, orientation caused by processing, cold crystallization, cure optimization, filler effects in composites, and much more. DMA provides an accurate measure of material stiffness (modulus) but also other important mechanical properties such as damping, creep, and stress relaxation.
A thermomechanical analyzer measures sample dimensional changes under conditions of controlled temperature, time, force, and atmosphere.
The Viscotek TDAmax is a complete stand-alone, research grade, temperature controlled, multi-detector GPC/SEC system suitable for the molecular weight and molecular size determination of proteins, natural and synthetic polymers, copolymers and other macromolecules.
Fourier transform infrared spectroscopy (FTIR) is a technique which is used to obtain an infrared spectrum of absorption or emission of a solid, liquid or gas. An FTIR spectrometer simultaneously collects high spectral resolution data over a wide spectral range. This confers a significant advantage over a dispersive spectrometer which measures intensity over a narrow range of wavelengths at a time.
Twin-jet UV-VIS unit, range of wave length 190-1100 nm, spectral frequency range 1 nm;
UV/Vis spectroscopy is routinely used in analytical chemistry for the quantitative determination of different analytes, such as transition metal ions, highly conjugated organic compounds, organic compounds, and biological macromolecules. Determination is usually carried out in solutions.
The Zetasizer Nano ZSP is used for the measurement of size, electrophoretic mobility of proteins, zeta potential of nanoparticles and surfaces, and optionally the microrheology of protein and polymer solutions.
The exceptional performance also enables the measurement of the molecular weight and second virial coefficient, A2, of macromolecules and kD, the DLS interaction parameter.
The SpectraMax® M2e Systems from Molecular Devices are multidetection microplate readers with dualmonochromators, dual-mode cuvette ports, and top- and bottom-reading capability. Detection modalities include absorbance (UV-Vis Abs) and fluorescence intensity (FI). Endpoint, kinetic, spectrum and area-well scanning read types and the PathCheck® Sensor allow homogeneous and heterogeneous microplate assays to be performed in one flexible system.
The TriStar II Plus is a an automated, three-station, surface area and porosity analyzer that delivers excellent performance and speed of analysis. With three available analysis ports, the TriStar II Plus provides high sample through-put and advanced data analysis features to the user. The unique stainless steel analysis manifold is corrosive resistant and designed for highly accurate gas management for confident and repeatable results.
Rapid Resolution Liquid Chromatography (RRLC) allows both fast (minute range) and ultra-fast separations (seconds range) with short columns as well as high-resolution separations with correspondingly long columns.
One of the core features of the RRLC, besides optimizing the LC instrumentation (for example with regard to pressure and dead volume), is the use of extremely small particle sizes (2 microns). For small particles, the mass transfer between and in the particles is optimized by a reduction of the diffusion paths so that the highest separation step numbers, ie the lowest peak widths, can be achieved. Separation capacities of 12,000 trays and more for 50 mm long columns are reality and correspond to the separation efficiency of a 150 mm long column packed with 5 μm particles.
The UltiMate® 3000 Nano LC systems have been designed to optimize low flow separations and facilitate easy coupling to mass spectrometry to provide the best resolution, sensitivity, and selectivity for nano LC and proteomics applications. Nano HPLC is a technique that generally involves the application of columns with an internal diameter of 75 µm and low flow rates of around 300 nL/min. These configurations are ideal for analysis with limited sample starting amounts, due to the sensitivity enhancement of the smaller column inner diameters.
The objective of preparative high-performance liquid chromatography (HPLC) is to isolate and purify a desired product from a compound, as opposed to an analytical HPLC run during which the qualitative and quantitative properties of a compound are determined.
The microscope is designed for all polarization microscopic investigations of mineral and microstructural characterizations up to conoscopic investigations in the extreme range. Its magnifying lenses can be used in a range from 2.5-fold to 100-fold magnification.
Compact, high-performance tabletop unit for effective lyophilisation of specimens in your everyday lab activities. The LDplus user interface makes the work very easy. You can choose from a wide range of configurations to adapt the freeze dryer optimally to your specific needs. The condenser temperature of -55 °C enables the drying of aqueous products. Ice condenser-, capacity 2,5 kg, performance 2 kg/24 h.
Easy, Safe, and Fast way to dry and dispense solvents. These systems operate by pushing the solvents through a series of drying columns resulting in moisture levels down to the ppm range. Dried solvents can then be either dispensed into a collection vessel directly at the system and/or into an integrated glovebox system.
