There is various analytical lab equipment that scientists can use in a lab that is either being set up or already has been. In addition, there are many types of instruments and pieces of equipment that will help you pursue your research. Some may be more suitable for your research than others. This article discusses some of the most common devices and their uses to help you stay informed about what to look for when purchasing new equipment for your lab.
Blood chemistry analyzer:
A blood chemistry analyzer is an important piece of Global Lab Supply Analytical Lab Equipment to have in your lab. This device can measure levels of different types of chemicals used in the body and determine how much is present within certain quantities. Using this information, a physician or scientist can determine which treatment strategies would be most effective for a patient by analyzing their chemical levels.
Mechanical devices use inflow tubes to pull a sample into them (which causes centrifugation), while electrical units have sensors that measure through light absorption and electronic circuitry to indicate results. Both types of chemistry analyzers are available in the global lab supply.
Column chromatography is an analytical technique used to purify a compound. This process uses a stationary phase in which the compound is dissolved. The sample then passes through an adsorbent column, which removes unwanted compounds from the solution. Once the unwanted compounds have been removed, the desired product can be recovered by the user from the column using a liquid solvent.
There are many ways to measure each molecule’s electrical currents in a solution. The most common way is to measure in direct current (DC) form, but there is also a way to make an electric potential of an object by analyzing the electric current that flows around it.
Gas chromatography is a method used for using different types of gasses, such as helium and nitrogen, to purify various compounds. The gas will be sent through the column, separating it into its primary components based on their different polarity characteristics.
The gas will then flow into the detector, where it will be detected individually. After being detected, a computer can be used by scientists to determine the amount of each compound present in the sample. Gas chromatography is important for fast-moving experiments as it does not require the researcher to wait for results; thus, it saves time.
Electrophoresis is a process in which an electric current transports charged molecules through a gel. As previously discussed, it is made of solid polymers that are insoluble in the liquid around them. The sample will flow through the polymers with charged particles suspended throughout the reactor. The molecules will then travel through the column based on their charge and size.
As it moves around the column, it will be detected by UV light to determine if, during the process, it has become separated into its components or not. Electrophoresis is commonly used for DNA sequencing applications such as genome sequencing for organisms that have been recently discovered; however, it can also be used by users for other purposes.
Analyzing the fundamental properties of a substance can be a crucial part of determining its chemical makeup. Elemental analyzers are often used for different organic compounds. Each device will use specific methods to determine the elemental makeup of what is being analyzed.
Melting Point Apparatus:
The top of the bell is made from quartz or similar materials, which scientists will use to heat the sample using a Bunsen burner underneath. The sample will then be placed onto a microscope slide, which is placed inside the chamber.
The temperature will then decrease, and after it dips below the compound’s melting point, the substance will begin to melt. When it does, it will either drip into a collecting area underneath or if there are holes on the side of the chamber and top of the cover slide, it can pass through and exit that way.
The polymerase chain reaction is a method for making tiny copies of a strand of DNA. There are many different kits available in the market to do the process, which involves a mixture of DNA strands, primers, enzymes, and other chemicals. The user will place the mix in the device, creating over 400 versions of the original strand under certain temperatures.
When acquiring a new piece of equipment, think about what you will use it for. Some devices are better suited to certain applications, such as a chromatography device that requires specific chemicals, while others are better at different applications. It is important to have the right equipment in your lab to get the best results and run your experiments faster while saving time and money.
