What does “Erlenmeyer flask” mean in chemistry? Kumar Jeetendra | March 11, 2023 Laboratory flasks with a flat base, conical body, and cylindrical neck are known as Erlenmeyer flasks. They are also sometimes called conical flasks or titration flasks. Emil Erlenmeyer (1825-1909), a German chemist, developed it in 1860 and gave it his namesake. Whether you call it a conical flask, Erlenmeyer flask, or something else entirely, it’s …
What to watch out for and how to use laminar flow hoods in the lab ? Kumar Jeetendra | March 11, 2023 Examples of laminar flow hoods are biological safety cabinets and clean benches (a.k.a. cell culture hood or tissue culture hood). These are HEPA-filtered laboratory enclosures that are carefully aimed. Several of these hoods guard against contamination of objects put on the work surface. Others shield the user from pollutants in the working environment. A laminar …
Everything You Need to Know About Design of experiments Kumar Jeetendra | March 11, 2023 Design of experiments (DOE) is a field of applied statistics that involves the planning, execution, analysis, and interpretation of controlled tests to determine the factors that govern the value of a parameter or set of parameters. Design of experiments DOE is a potent instrument for data collecting and analysis that can be utilised in a …
Did you know? Multivariate data analysis(mvda) in pharma industry Kumar Jeetendra | March 11, 2023 In today’s society, we have access to enormous amounts of data, therefore, it is of the utmost importance to evaluate and manage this data in order to make use of it for anything meaningful. The terms “data” and “analysis” are often used interchangeably because the two processes are interdependent. Data analysis and research are also …
What makes a peak broad in gas chromatography? Kumar Jeetendra | March 6, 2023 An analytical technique known as gas chromatography (GC) is used to identify, separate, and quantify the chemical components of a sample mixture. Often, these chemical components are gases or organic compounds. These components must be volatile, typically with a molecular weight below 1250 Da, and thermally stable to avoid degradation in the Gas Chromatography system in …
Benocyclidine: Everything you need to know Kumar Jeetendra | March 5, 2023 Benocyclidine is a recreationally used psychoactive substance that is related to phencyclidine. Benocyclidine is a member of the arylcyclohexylamine class of drugs. It is also known by the acronym BTCP, which stands for benzothiophenylcyclohexylpiperidine (PCP). In 1997, a patent application authored by Marc Caron and colleagues at Duke University included the first description of the …
What does a spectrophotometer measure? Did you know? Kumar Jeetendra | March 4, 2023 A spectrophotometer is a piece of apparatus that measures the amount of light that is absorbed by a specimen. In more depth, spectrophotometer techniques are most commonly used to measure the concentration of solutes in solution. This is accomplished by determining the amount of light that is absorbed by the solution in a cuvette that …
5 Key Differences of Spectrophotometry vs Spectroscopy Kumar Jeetendra | March 4, 2023 Spectrophotometry is a method for determining the amount of light a chemical substance absorbs by measuring the intensity of light as a light beam passes through a sample solution. The fundamental idea is that each substance absorbs or transmits light within a specific wavelength range. This measurement can also be used to determine the concentration …
HPLC calibration curve: Everything You Need to Know Kumar Jeetendra | March 4, 2023 In analytical chemistry, the concentration of an unknown sample solution can be found out using a calibration curve. It is an experimentally generated graph with the concentration of solution plotted on the x-axis and the observable on the y-axis. Calibration curves are primarily used to determine the concentration of an unknown sample. Standard solutions with …
Is NH4OH soluble in water? Everything you need to know Kumar Jeetendra | March 4, 2023 Ammonia dissolved in water has the chemical formula NH4OH. This liquid goes by several other names, including ammonia water, ammonium hydroxide, ammonia liquor, and aqueous ammonia. “NH3 (aq)” is a common shorthand for NH4OH. Ammonia dissolves in water because each water molecule gives the NH3 molecule one of its proton. This results in the creation …
Lab Safety Rules in Pharmaceuticals : All you need to know Kumar Jeetendra | March 3, 2023 The safe usage of a lab and its related equipment are referred to as lab safety. Chemical maintenance, hazard control, risk evaluation, and occupational injury prevention are all important parts of lab safety. The golden rule for lab safety is to be ready to handle a crisis before it occurs as prevention is always better …
Eppendorf Centrifuge 5910 Ri is the first My Green Lab ACT-labeled centrifuge Kumar Jeetendra | March 2, 2023 The Eppendorf refrigerated Centrifuge 5910 Ri has been certified with an “ACT®” Environmental Impact Factor Label by the “My Green Lab®” non-profit organization. By emphasizing Accountability, Consistency, and Transparency (ACT) around manufacturing, energy and water use, packaging, and end-of-life, the ACT label makes it easier for labs to choose more sustainable products. ACT-labeled products are independently …
