Automatic Bench Top Digital Refractometer For Testing Beverages By: Kathy Brasch | - The soft drink industry produces beverages such as fruit juice, energy drinks and carbonated drinks. One of the key factors in producing these beverages is maintaining consistency between batches of their product for quality control and process control. In order to keep this consistency the manufacture needs to test the product to determine the total concentration of water-soluble solids (Brix value). For practical purposes the Brix value is generally interpreted as sugar content because soft ... Tags:salinity solution, pal refractometers, PAL carrying case
Salinity Measurement By: Kathy Brasch | - Measurement of the level of salinity in soy sauce, ketchup, dressing, soup, seasonings, pickled juices of vegetables, etc. is indispensible for quality control. One of the key factors in producing these products is maintaining consistency between batches of their product for quality control and process control. In order to keep this consistency the manufacture needs to test the product to determine the total concentration of salt. Highly concentrated samples such as soy sauce need to be dilut ...

Refractometer Applications By: Kathy Brasch | - In the world of refractometers there are many different models and styles. They can measure a wide variety of products from many different industries. Products include, but are not limited to:
Immersion Oil Use In Compound Microscopes By: Kathy Brasch | - As magnification increases on a compound microscope the correction in refractive index is a requirement for finer resolution and brightness. As the light cone passes through the different layers of glass, sample mounting media and air light tends to bend at different angles. In most cases the sequence of the light leaving the substage condenser is glass (1.515nD), air (1.00nD), glass slide (1.515nD), sample, mounting media, cover slip (1.515nD), into the objective lens which is approximately 1 ...

Properly Setting Up Koehler Illumination By: Kathy Brasch | - You have heard of the term Koehler illumination. What is it and what does it do for the microscope?
Koehler Illumination is a process which provides optimum contrast and resolution by focusing and centering the light path and spreading the light evenly over the field of view. All microscopes do not have the ability to be setup for Koehler. They must have a field diaphragm and controls to adjust the substage condenser to complete the alignment.
Digital Cameras For Microscopes By: Kathy Brasch | - Since the introduction of digital photography with a microscope, many techniques have been developed regarding image enhancement or modification, information extraction and the procedural ease of which to accomplish capturing extremely high resolution photographs with computers and software.
The days of using 35mm film, capturing many images of delicate volatile samples only to find out you had a setting wrong, the lighting was incorrect or the film was too old and all the pictures ... Tags:microscope camera, digital microscope camera
Stereo Microscope By: Kathy Brasch | - Stereo microscopes or dissecting microscopes are one in the same instrument the name is often used interchangeably. They are used for looking at specimens with a three dimensional view. In reality stereo microscopes are like having two compound microscopes looking at the focus point of reference at slightly different angles, thus creating a three dimensional image. The magnification level is much less than that of a standard upright compound microscope. Magnification for stereo microscop ... Tags:microscopes, stereo microscopes, microscope camera
Abbe Refractometers By: Kathy Brasch | - Refractometers are measuring instruments which put the phenomenon of light refraction (bending) to practical use. They are based on the principle that as the density of a substance increases (such as when sugar is dissolved in water), its refractive index rises proportionately. Refractometers were devised by Dr. Ernst Abbe, a German/Austrian scientist in the early 20th century.
Principals Of Refractometers By: Kathy Brasch | - Water is placed in a reservoir. When a pencil is dipped into the water, the tip appears bent. Now put concentrated sugar water into a cup and try the same thing. The tip of the pencil should appear even more bent. This is the phenomenon of light refraction. Refractometers are measuring instruments in which this phenomenon of light refraction is put to practical use. They are based on the principal that as the density of a substance (e.g. when sugar is dissolved in water), it's refractive index r ... Tags:refractometers, abbe refractometers, brix refractometers
