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.
Brix Refractometers By: Kathy Brasch | - You often hear the term brix and brix refractometer when testing samples for sugar content. Just what is a refractometer? A refractometer is an instrument that measures the refraction of light through a substance. The refractive index becomes higher in a substance of higher concentration.

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
How A Polarimeter Works: A More Detailed Explanation By: Kathy Brasch | - Light waves as it travels. As shown in Figure 1, light may seem to travel unidirectionally. In actuality light travels in all directions as shown in Figure 2.

Basics In Tropical Fish Care By: Anika Woods | - Giving you tips on how to take care of every single one of the 20,000 fish that are out there would be impossible. But I can give you basic tips on taking care of an aquarium. While animals are usually protected by their coat, fish don't have that option. That's why they need the temperature of the water to be just right for them. If the temperature is high, the supply of the oxygen is minimized. If it's low, then their health can be affected.
Import Measuring Instruments And Other Precision Testing Equipment From Japan By: Chris Robertson | - It never ceases to surprise me how business has changed over the course of my own career.
