- 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: 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.
(Detail With Image on Blog - Microscopes)
When light, which waves in all directions, goes through a grating placed in its course of travel, only the light wave that oscillates in the direction parallel to the bars of the grating passes through, Light waves that oscillate in other directions get blocked by the bars ...

- 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 ...

- 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.
When you bought your aquarium, you p ...

- 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. When I first started out as a new college graduate, the standard mode of operation for just about any business was making a product and then selling it. That is still being done to some extent, but in a global economy doing business is increasingly a matter of recognizing a need, locating the product to fill that need, and then setting up the appropriate way of making the product available on the market. Th ...

- The Days When Home Winemakers Were Mere Amateurs Are Behind Us
By: Don Saunders | - In the days of the Roman Empire 'amateur' meant 'lover' and referred to an individual who did something from a love of doing it, and not for any financial gain. Such individuals were thought of as the finest of experts because they honed their craft motivated by mere joy for their work.
Although wine professionals continue to fill their work with passion and skill, amateurs, assisted by modern technology and knowledge passed down over the centuries, can generally now produce simil ...
