- 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.
The prism in a refractometer has a greater refractive index than the sample solution. Measurements are read ...

- 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.
A refractometer has a wide variety of uses such as measuring sugar concentrations and liquid concentrations. Refractometers are sometimes called Sugar concentration meters or Density mete ...

- Used Microscopes
By: Kathy Brasch | - Remember back to your school days when you first saw amoeba swimming around in pond water? You thrilled to seeing the microscopic organisms moving around, bumping into each other. Now you want to share that memory with your children or grandchildren as they grow. But you dont want to spend their college money on a new high-priced microscope, so what can you do? No problem you can now find many microscopes that are either used or demo models at a much more reasonable price. But first ...

- 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 ...

- How A Polarimeter Works
By: Kathy Brasch | - The Simple Explanation
Imagine tying a piece of thick rope to a hook in a wall, and then shaking the rope vigorously. The rope will be vibrating in all possible directions - up-and-down, side-to-side, and all the directions in-between - giving it a really complex overall motion. Now, suppose you passed the rope through a vertical rectangular hole, like this: []. The rope has a really tight fit in the hole. The only vibrations still happening at the other side of the hole will be v ...

- Choosing A Microscope: Compound Or Stereo Microscope?
By: Kathy Brasch | - to see and what you want to do with that image will determine what kind of microscope you need. Microscopes typically come in two types: compound or stereo microscope.
The most common is the compound microscope. It is the one most people visualize when they think about microscopes. A microscope with one eyepiece is called a monocular microscope; with two eyepieces it is called a binocular microscope, or it might have an additional camera tube and is called a trinocular microscope. The c ...
