A magnetic stirrer is a tool that creates a stir bar submerged in liquid using a revolving magnetic field to aid in blending any solution. A rotating magnet combined with another revolving field beneath the vessel or stationary electromagnets can produce a rotating magnetic field. There are various magnetic stirrers, such as mini stirrers , magnetic stirrers & timers, etc. Are available in the market. This kind of equipment is among the easiest to produce combinations. Magnetic stirrers' primary use is to stir liquids to hasten reactions or improve mixes. For sample preparation and analysis, magnetic stirrers are frequently employed in chemistry and biology studies. These stirrers should only be used with glass or non-metallic beakers to prevent interference with the magnetic field. A hot plate is frequently part of a magnetic stirring system to heat the liquid and maintain the conditions necessary for the mixing solution. The temperature of the magnetic hot plate that warms th...

Demand for an easy test to assess milk quality emerged in the late 19th century in response to a growing interest in nutrition, pure foods, and truth in labeling. During that time, milk was sold by its weight. As a result, some farmers began to dilute their products or remove the cream from the top, punishing the sincere ones while introducing unpredictability into the milk supply for consumers. Professor Stephen M. Babcock (1843–1931) of the University of Wisconsin was tasked with coming up with a solution to this problem, and in 1890 he published the Babcock test with the help of Babcock bottles . Older tests, however accurate in detecting milk-fat levels, were too time and money-consuming to be extensively used. Dairymen immediately adopted Babcock's test's straightforward, cost and time-efficient answer. The test served as an effective method for establishing fair milk pricing based on quality and a helpful tool for animal breeding. Farmers could breed their herds for bette...

Western blotting is a method for identifying a specific protein with the help of blotting paper in a sample that contains other proteins. Each western blot experiment uses a specific antibody against a particular protein. These antibodies attach to the target protein and aid in its later quantification. The study method known as western blotting is widely used in molecular biology, immunology, and allied sciences. Western blotting is essential for students who want to work in these fields. However, novice students learning about it could find the lessons frightening. Fortunately, there are numerous approaches to making it more interesting and approachable. Here are five suggestions for educators to make the subject more engaging based on students' challenges when learning about Western blotting. Each item of guidance addresses a specific issue that students encounter. Explore Real-World Applications HIV-AIDS diagnosis can be made via Western blotting. The method is specifically us...

Labs use electrophoresis to examine medicines, vaccinations, forensics, DNA profiling, or other life science applications. The method is also employed in fields like food science and mining with the help of electrophoresis accessories . In gel electrophoresis, proteins or nucleic acids move across a porous gel matrix. Proteins and nucleic acids both have a net-negative electrical charge, which is used to help the target molecule move more easily across the medium. Proteins and nucleic acids can be separated using gel electrophoresis according to their size. Horizontal Gel Electrophoresis During horizontal gel electrophoresis, a horizontally cast gel is immersed in a running buffer inside the gel box. The ionic running buffer creates a charge gradient when a current is delivered. A layer of agarose gel divides the two chambers in the gel box. A cathode is situated at one end, and an anode at the other. The gel, which warms up as a charge is applied, is cooled by the buffer. The running ...

Once you have invested in a lab centrifuge, you want to ensure it continues functioning effectively for as long as possible. Maintaining your device properly can help with that and ensure your safety and the seamless operation of your application. We look at how to keep your lab centrifuge in great shape through regular maintenance, such as cleaning with centrifuge brushes , etc., in this blog, including: Examining components for damage Getting regular maintenance done Lubricating and cleaning the apparatus Let's take a deeper look at each of these. Check for Damaged Parts Periodically inspect the device for any indications of damage. It is not advisable to utilize damaged rotors, adapters, buckets, lids, tubes, or plates. Here are some illustrations of what you might see: Parts exposed to salts, moisture, and harsh chemicals, such as the rotor and buckets, have corroded over time. There may be minor surface blemishes, cracks, or holes in the rotor or buckets. Damage to the lid gas...

The beaker is one of the lab's most often-used pieces of equipment. Beakers are used in experiments that produce liquid products to collect the liquid. Beakers can hold samples of anything you're researching at the most fundamental level. They can serve various other purposes because they come in multiple sizes, including sustaining a minor chemical reaction. Plastic beakers are frequently used in research, instruction, and industry. They are also employed in tests using chromatography. The Advantages of Plastic Beakers Cost   Glass is far more expensive than plastic, and plastic laboratory supplies like beakers can be thrown away without meticulously cleaning. In addition, unlike glass, plastic may be twisted and squeezed. Durability Plastic has the unique benefit of being less delicate and breakable compared to glass. Glass lab equipment frequently breaks while being cleaned and prepared for use. However, it becomes even more crucial when glass breaks while conducting an ex...

Research is crucial to our being as it uncovers answers to long-due questions. According to UNESCO.org, there were 7.8 million researchers in 2013, which has positively increased to a great capacity. Finding solutions to existential questions fills the knowledge gaps that the human race has been facing for many years. Different kinds of research take place worldwide – some are related to health, diseases such as cancer and Parkinson's, others are about neurology or physics, and so on. We cannot hinder the significance of any research; all of them are equally important and hold massive significance to evolution and scientific advancement. For research, scientists take samples, which must be kept safe and secure until they are required. Some of them need to be kept for months and years even. This is where the usage of desiccator cabinets comes into the light. Before we embark on what desiccator cabinets are – it is of significance that the definition of it is clear and easy to grasp...
