Sieve range is the focused answer to all typical sieving tasks in the laboratory. The sieve shakers are well-conceived instruments for dry, wet and micro-precision sieving from 0.05 g up to 15 kg. Thanks to various sieving motions (throw action, horizontal, tapping, sonic, etc.) and sieve sizes it is possible to select the ideal instrument for practically any bulk material. The instruments produce exact and reproducible results and comply with the requirements for the test materials monitoring according to international standards. All sieves are carefully tested prior to delivery.
Knowing the sound level is important since harmful levels can cause sound-induced hearing loss and, therefore, create a vast damage to people’s hearing if in the near vicinity of loud sounds. A sound level meter or sound meter is an instrument that measures sound pressure level, commonly used in noise pollution studies for the quantification of different kinds of noise, especially industrial, environmental and aircraft noise. A range of hand-held sound level meters and accessories is offered to cover all possible requirements, from level checks to in-depth analysis.
Lab reactors are the ultimate systems when it comes to optimizing and reproducing chemical reaction, mixing, dispersing, and homogenization processes on a lab scale. The lab reactors can be individually customized to perform numerous tasks ranging from casual high pressure catalytic hydrogenation to production of cr?mes and lotions, grinding and disintegrating of solids and fibers in liquids or polymers. Durable, safe and reliable single-walled or double-walled vessels made from borosilicate glass or stainless steel are available, each with or without bottom discharge valve.
Moisture analysis covers a variety of methods for measuring moisture content in both high level and trace amounts in solids, liquids, or gases and is used in many fields from food to polymer industry. Classic moisture analyzers use loss-on-drying (LOD) measurement technique while more advanced machines may employ spectroscopic methods. In LOD technique a sample of material is weighed, heated in an oven for an appropriate period, cooled in the dry atmosphere of a desiccator, and then reweighed. Moisture analyzers integrate all of the necessary components into a single convenient machine.
In laboratories, production, and quality control, as well as schools, universities, and specialty stores, modern balances are renowned as premium quality, high-precision weighing instruments for weighing to the nearest 0.0000001 g up to several hundred metric tons. Computer interface that is present in many modern balances allows to easily track and document measurements while internal and external calibration systems ensure that the measurement results are as close to real values as possible.
Conductivity is a parameter used to measure electrical properties of a solution. Conductivity measurements are used for applications such as in the production of ultrapure water or determining the salinity of saltwater. It is evaluated by making a direct measurement of the electrical resistance. The more ions in the solution, the greater the current which flows between the electrodes. The instrument measures the current and uses Ohm’s law to calculate first the conductance of the solution and then – by taking the cell data into account – the conductivity.
The viscosity of a fluid is a measure of its resistance to gradual deformation by shear stress or tensile stress and its measurements are performed using viscometers or rheometers. Rheometer is used for those fluids which cannot be defined by a single value of viscosity and therefore require more parameters to be set and measured than is the case for a viscometer. Classic viscometers are simple glass capillary devices while modern automatic machines use falling ball, oscillating piston, vibrating plate, rotational or other measurement method and perform calculations providing user with processed data.
Spectrophotometry is the quantitative measurement of the reflection or transmission properties of a material as a function of wavelength. Meet analytical and educational challenges with the complete line of Ultraviolet-Visible (UV-Vis) spectrophotometers from innovative microvolume machines for life scientists, to breakthrough solid sampling accessories for high-end materials research. It is certain that there is a UV-Vis spectrophotometer that meets even the most specific, strict teaching and analytical needs.
