Product description Linkam Optical “Shearing” System
The Linkam Optical Rheology CSS450 for Life Sciences, Food Research and Plastics.
The CSS450 internship was developed in collaboration with the University of Cambridge. It is a unique optical instrument that creates unique images of samples under different shear conditions and temperatures. The images are of very high quality and resolution and suitable for various applications: Life Sciences, Food Research, Plastics and Polymers:
The Linkam CSS450 Optical Shearing System allows the user to examine the complex rheological properties of liquids under a microscope, controlling the temperature between -50°C and 450°C and varying the shear rates. The distance between the plates is adjustable between 5 and 2500 µm, the speed of the change of the plate distance can also be set.
Life sciences: The CSS450 is being used by several researchers to advance groundbreaking research on biological materials, from blood analysis to artificial muscle characterization. The CSS450 stage can also be used to observe “stress” or “stretching” of biomaterials, as well as fluid flows and mixing of fluids.
Many well-known food and beverage manufacturers and food scientists use the CSS450 to simulate and image the mixing behavior, emulsion formation and temperature stability of frozen foods.
Plastics and polymers
Within the field of materials testing, the CSS450 is ideal for testing emulsions and polymer melting points, composite materials and rubbers. It provides insight into shear properties through image analysis.
Wide temperature range
The temperature range ranges from –50°C (with the addition of an optional LNP96-D) to 450°C for a versatile range of experiments.
To study the microstructural changes of complex fluids there are several shear options oscillating, stable and step by step.
Variable Spacing Settings
The distance between the plates (top and bottom) can be varied between 5μm – 2500μm allowing different sample sizes and textures to be measured.
Complete heated stage and lid
The stage and lid are independently equipped with heating units ensuring a uniform temperature between stage and lid.
The CSS450 has been used successfully with SAXS/WAX or synchrotron equipment to characterize samples undergoing shear stress. Linkam can supply Kapton or Mica windows instead of quartz (standard).
