Spotlight Microtehnology & Nanotechnology The Perfect Solution for Particle Size Measurements
The Laser Particle Sizer ANALYSETTE 22 MicroTec plus from Fritsch fascinates with an unachieved union of extra-wide measuring range 0.08 µm (80 nm) up to 2000 µm, high resolution, consistent reproducibility, marginal space requirements and a reasonable price. Any particle size measurement is only as good as its dispersion. For this reason, we place great importance on this aspect and bring all our experience to bear. Perfectly conceived dispersion units - Fritsch developed the ANALYSETTE 22 MicroTec plus as an especially practical modular system with perfectly conceived units for dry and wet dispersion, for dispersion in a free jet or for combination with a small volume wet dispersion unit. When switching between wet and dry measurement, the measuring cell, which is located in a practical cartridge, can be easily exchanged – without changing any hoses or modifying the instrument. The cartridge you are not using now, can be easily stored within the dispersion unit.
Variable measuring range - with the ANALYSETTE 22 MicroTec plus, users can easily and fully automatically choose between two individual measuring ranges or combine the two into a third option offering maximum flexibility and a total measuring range of 0.08 µm – 2000 µm in a single instrument with an outstanding resolution of up to 108 measuring channels. Full programmability - due to the especially flexible MaS control software, the entire measuring process of the ANALYSETTE 22 MicroTec plus can be selected via Standard Operating Procedures SOPs or can be fully custom-programmed to perfectly satisfy your requirements. The analysis of the measuring data takes place fully automatically according to standard reports or via the freely editable Fritsch report generator, which offers flexible options for displaying the measuring results according to your individual needs. The ANALYSETTE 22 MicroTec plus makes particle size measurement to the simplest thing in the world and this with extremely short analysis times, consistently reproducible and reliably comparable results in all fields of application for wet or dry measurement of particle size distributions.

Small, Smaller, Ministat
Huber Ministats are the smallest cooling thermostats in the world. Despite their size Ministats have enough power to thermoregulate photometers, refractometers, viscosimeters, distillation apparatus, reactor vessels and mini plants and their compact form allows them to be placed in areas where space is at a premium, for example laboratory extraction hoods. Ministats can be used to control externally closed applications or alternatively objects can be thermoregulated directly within the bath.
The Ministat range consists of 3 models, which are available as either air or water cooled versions. Depending on the model, working temperatures are from -45°C to +200°C and cooling capacities of 600 watts can be achieved. The maximum admissible environmental temperature for continual operation is +40°C. A powerful variable speed pressure/suction pump allows optimum circulation and can be controlled using an optional pressure sensor, which protects delicate glassware. For energy saving and reduced heat dissipation all models have active cooling control, which regulates cooling in the event of a temperature rise or drop and ensures Ministats use only the energy they need. The professional CC-Pilot controller comes as standard with TFT Display, six language options, RS232, sensor calibration, calendar and clock function, Auto-Start, adjustable safety limiting values and alarm signals. Available in three software options, the CC-Pilot can be easily electronically upgraded to extend functionality and activate further features such as: programmer, cascade control, ramp function, user menus, calendar start and graphic display. Analogue connections according to NAMUR are available via the optional Com.G@te module, which enables integration into plants and process control systems.

Linkam Scientific Instruments announce the use of their temperature controlled tensile stage by the Mather Group at Syracuse University. Patrick Mather is Professor of Biomedical and Chemical Engineering at Syracuse University. His research group focuses on functional materials: in particular, the development of polymeric and hybrid materials with prescribed functionality beyond traditionally passive mechanical roles. The applications range from medical to structural materials technology. Utilising the core experimental strengths of Syracuse Biomaterials Institute, such as polymer synthesis, rheology and processing, morphological analysis, quantitative thermal analysis and mechanical testing, the group pursues the development of these functional polymeric systems.
Professor Mather selected the Linkam TST350 tensile stage for his micro/nanoscale mechanical property studies because it provided accurate temperature and torque control while having open architecture for modification for more advanced measurements. With graduate students Erika Rodriguez and Xiaofan Luo, protocols for the evaluation of self-healing polymeric films were developed. Typically, the stage is used with a 200N load cell to uniaxially stretch samples to a displacement of 10 mm (corresponding to a strain of 60% at a displacement rate of 0.1 mm/s (0.6%/s) at RT. The study is repeated after thermal annealing of the sample, which causes the sample to fully recover its original shape. This is to analyse whether the mechanical properties of the sample were compromised from the first stretch. Further custom experiments are also performed using a double edge notch punch. The Linkam TST350 enables the study of the tensile properties of samples relative to their temperature. Mounted on an optical microscope or Linkam Imaging Station, it is possible to capture high-resolution images of the structural changes. The TST350 is built with two precision ground stainless steel lead screws to maintain perfect uniform vertical and horizontal alignment. Sample jaws move in opposite directions to maintain sample in both reflected or transmitted microscope fields of view. This also means other transmitted techniques such as x-ray, needed for internal observation of sample structure can be used. Importantly for environmental control, the sample chamber is gas sealed and can be controlled with various gases via the gas valves built onto sides of the stage.
