How to Repair a Refractometer

A refractometer is a laboratory device -- or sometimes a field device, in the case of handheld versions -- which is used to measure the index of refraction. Modern refractometers, such as brix refractometer ,salinity refractometer, give out detailed readings which are based on the tightest parameters, and reliant on sufficient power reaching the system to facilitate the unit to work. Any number of things could go wrong with the process -- some of which will require the unit to be sent for servicing, but some which you could carry out yourself if you have the expertise.


What Are Critical Control Points in the Wine Making Process?

There are slight differences to how people make wine at home, according to their personal preference. However, there are several points that are critical for the wine making process to be successful. Also, it is important to remember to use equipment, containers and bottles that are thoroughly sanitized.The refractomers such as grape refractometer,alchol refractometer and brix refractometer are the important tool.


Instructions for the Use of a Refractometer

A refractometer such as brix refractometer or salinity refractometer is a laboratory device used to measure the index of refraction of light as it passes through a solution. This measurement allows the concentration of a solution to be calculated; also, any foreign substances can be identified.


How to Cycle a 24 Gallon Salt Water Tank

The nitrogen cycle is the life support system of an aquarium. The cycle is a chain of chemicals and bacteria that are responsible for keeping the aquarium free of organic waste. Without an effective cycle, the tank becomes a toxic soup of chemicals that will harm or kill the inhabitants. To get a new aquarium ready for fish, it is essential to biologically mature the filter by encouraging the growth of highly specialized bacteria in the filter system. This process is vital for the safety and welfare of all aquatic animals.The salinity refractometer , aquarium refractometer or seawater refractometer is a important tool.


How to Calculate Hydration Levels

Knowing your body's hydration level is important for maintaining a normal level of water. Water makes up for 60 percent of body weight and the body uses it to monitor temperature, protect organs and joints, transport oxygen to cells and eliminate waste. If body fluid is lost and not replaced quickly, dehydration occurs. You lose water through perspiration, urination and respiration. Calculating body hydration can ensure you are maintaining a healthy water intake amount. There are three common methods  such as refractometer, Sweat Patches, Urine Color Chart to measure body hydration levels.


How to Make a Pinhole Refractometer

Distinguishing an aquamarine gem from a blue topaz or a synthetic blue spinel is not easy. The trouble is aquamarine is by far the most valuable gem. So if you can't distinguish it from inferior stones, you could be in for an expensive and disappointing mistake. The same problem arises with other precious stones. Gemologists have a selection of tools to help them identify the type of stone they are examining, which you can also learn to use. Among them is the refractometer. Refractometers test a stone's ability to bend light by measuring the angle created by a ray of light's path before and after it passes through a gem. Every stone has a unique refractive index, so if you can measure the refraction index, you can identify the stone.


How to Identify Colored Gems

Colored gemstones can appear as similar stones of different colors, but the chemical properties of these gems give them each their unique characteristics. Therefore, identifying a colored gemstone is not just about matching the color with a name, but also about determining whether a colored gemstone is natural or man-made. Synthetic gemstones are made to resemble real gemstones, but the chemical properties of synthetic and real gemstones are inherently different. With the proper equipment such as refractometer and knowledge of gemstones, you can differentiate between natural and synthetic gems.


Refractometer Gem Identification

Each type of gem has its own refraction index, a measurement calculated with a refractometer. The instrument can help you identify what kind of gem or stone you have.


How to Make a Refractometer for Kids

A refractometer measures the angle of light as it hits the surface of a reflective surface, for example, that of a gemstone. Make a refractometer that a child can use to differentiate one type of gemstone from another. Supplies from around the home will be supplemented with supplies from an electronics store. Inexpensive gemstones, including artificial ones, can be acquired from a hobby store or a crafts supply house.


How to Use an Atago Refractometer

A handheld digital refractometer measures the refractive index of a solution, based on how light bends, or refracts, when traveling through the solution. This allows the user to determine the concentration of sugars, salts, proteins or minerals in a sample. One of the most common applications for a refractometer is checking sugar levels in drinks at beverage plants and breweries. The Atago refractometer can measure hot and cold samples on its prism surface. The percentage displayed on its digital readout shows the total concentration of soluble solids in the sample.
