The Colorimeter in the Food Industry
Precision is key when it comes to manufacturing and producing food and drink. Consumers have high expectations regarding the quality of the products they buy, and companies must meet these expectations to maintain a successful business.
Determination of pH by means of the Colorimeter
A colorimeter is a device used to measure the pH of a solution. It is based on the fact that the pH of a solution affects the color of the solution. The device measures the color of the solution and, from that measurement, calculates the pH of the solution.
How does the Transparent Water Bath work in the Lab?
Transparent water bath is a common piece of equipment in many laboratories. It is used for a variety of tasks, including culture incubation, serologic sample testing, and warm-up reagents. The bathroom uses a heating element to maintain a constant temperature, usually between 37 and 60 degrees Celsius. The water is kept circulating by a pump, and the level is maintained by a float switch.
Using Water Baths to Conserve Serologic Tests
Biopreservation is the science of protecting biological samples for future use. Samples may be retained for a variety of reasons, including scientific research, legal evidence, or historical record. There are many different ways to store samples, but one of the most common ways is to use water baths.
How is the filter change performed in the water purification system in the laboratory?
Water production and maintenance of a water purification system should be simple processes. However, if proper maintenance practice has not been followed, they may become a problem. In particular, the aspect related to water production is important, because the water quality standards for the laboratory are strict. Water purification systems need to be able to meet the requirements of these standards, consistently and at the appropriate volume.
How to store water from the water purification system in the laboratory?
The amount of water produced by the purification systems of the laboratories is sometimes insufficient for the demand that must supply, so the storage of pure water (type II) is used for the production of ultra pure water (type I).
The Rotary Evaporator in the Biology Laboratory
A rotary evaporator is laboratory equipment designed to facilitate the evaporation of liquids at high temperatures. It is an essential tool in the biology laboratory, where it is used to concentrate samples and perform other tasks related to research. The rotary evaporator consists of an evaporation tank, a heating unit, a condensing unit and a vacuum pump. All these elements are connected to each other by a series of pipes and hoses.
Why is the Rotary Evaporator the most used distillation equipment?
The rotary evaporator is a very useful tool in laboratories, since it allows the elimination of volatile solutions efficiently and safely. The equipment can also be used to distill liquids and extract essential oils from plants. Since its invention in 1950, this equipment has been perfected and is now one of the most used tools in many laboratories. Technology has allowed miniaturization, making it easier to use in more compact applications.
Why is it more efficient to use a Rotary Evaporator to concentrate laboratory samples?
A rotary evaporator is a very useful and efficient instrument for concentrating samples in the laboratory, since it allows the solvent to be evaporated in a controlled way and leaves the sample in the container without damaging it. This is very important, as it prevents the loss of the sample and ensures a correct concentration.
Maintenance of Rotary Evaporators: how to extend the service life?
Rotary evaporators are an essential part of laboratory equipment, and their proper maintenance is crucial to ensure optimal operation and extend their life. It is a device used to remove solvents from mixtures by evaporation. A boiling V-shaped flask with a capacitor above is used. A vacuum is created in the flask which causes the liquid to boil at a lower temperature. This allows the solvent to be withdrawn without damaging the other ingredients in the mixture.
