    • Mannitol Salt Agar

      Mannitol Salt Agar

      In order to grow a bacterial culture in a lab, a growth medium has to be used to provide the right environment. Mannitol salt agar is a popular bacterial growth medium that biologists use to grow halphile bacteria (these grow fast in high salt concentrations) and can tell the difference between non-pathogenic and pathogenic Staphylococcus

    • Magnesium Anodes

      Magnesium Anodes

      Sacrificial anodes are used in cathodic protection systems in order to protect the primary metallic component(s) from corrosion. A magnesium anode is a type of metal used on boats and ships in order to protect the vessel’s other metallic parts. It first protects the area’s less active metal and acts as a corrosion barrier. How

    • Brookfield Viscometer

      Brookfield Viscometer

      The Brookfield Viscometer makes it possible to measure viscosity by employing techniques in viscometry. Viscometers (which can also be called viscosimeters) can measure viscosity through the varying flow conditions of the sample material being tested. They employ a spindle on a shaft that is designed to be dipped or immersed into a liquid that is

    • Adhesive Removers

      Adhesive Removers

      An adhesive remover is a chemical that can break the chemical bonds of adhesives. There is a wide variety of adhesive removers because there are many different types of adhesives. Each adhesive on the market has a slightly different formula/chemical structure. Therefore, an adhesive remover must be specifically formulated to break down each adhesive. Adhesive

    • What is Phosphorescence?

      What is Phosphorescence?

      Phosphorescence is an effect in which some chemicals re-emit light that they absorb. It is similar to fluorescence, except that the chemical reactions within phosphorescent materials happen less often, thus they take longer to emit light. Phosphorescent materials can be recharged by being exposed to light and may store light for several hours before it

    • Vibration Dampeners

      Vibration Dampeners

      A vibration dampener is any material that is designed to absorb vibration. People come in contact with vibration dampeners on a daily basis. Some examples are carpeting, foam, rubber, and grass. Vibration dampeners are exceptionally useful in situations where heavy machinery is repeatedly colliding with itself or another surface, especially a floor. Vibration dampeners can

    • How Does the Biuret Test Work?

      How Does the Biuret Test Work?

      The biuret test is one in which a researcher can determine whether a mixture has peptide bonds in it or not. By using the biuret test, in seconds an individual knows if they are there. Once they know that the peptide bonds are, in fact, there, they can then attempt to measure the amount of

    • What is a Plasma Cutter?

      What is a Plasma Cutter?

      A plasma cutter is a device that directs an ionized gas at an object under extreme temperatures. Plasma cutters are often used for industrial purposes, such as cutting metal, and are dependent on plasma, an extremely hot state of matter. Plasma cutters are essentially a type of plasma torch meant for cutting metal rather than

    • What is a Polyolefin?

      What is a Polyolefin?

      One of the largest classes of organic thermoplastic polymers is polyolefin. Polyolefin is an odorless, non-polar, and non-porous material that is used in structural plastics, consumer goods, industrial products, and food packaging. Polyolefin means “oil like” and is commonly referred to as a thermoplastic or polyalkene since polyolefin has a waxy texture. This substance is

    • ESR Spectroscopy

      ESR Spectroscopy

      ESR Spectroscopy (Electron Spin Resonance Spectroscopy or Electron Paramagnetic Resonance Spectroscopy) is a technique used for studying chemical species that have one or more “free radical” or unpaired electrons. Most stable molecules only have paired electrons without any free radicals, so ESR Spectroscopy is used less often than NMR (Nuclear Magnetic Resonance) Spectroscopy, the usual
