Organic chemistry: How do you operate a rotary evaporator?
Organic chemistry is the branch of chemistry that is responsible for the study of the structure, properties, synthesis and reactivity of chemical compounds formed mainly by carbon and hydrogen, which may contain other elements, usually in small proportion as oxygen, sulfur, nitrogen, halogens, phosphorus, silicon. That is, organic chemistry is the study of organic substances and compounds, being the constituent compounds of the different forms of living beings on our planet.
What is the usefulness of a Rotavaporador in a laboratory?
A Rotavaporador is an equipment that in general has different uses in laboratories and other areas of application; it serves to separate the basic components of a solid, by distillation and subsequent condensation; it can also be used as a multifunctional system in combination with a vacuum pump, a vacuum controller and circulation coolers.
Rotavapor why is it fundamental in a laboratory?
A wide variety of examinations, experiments and endless chemical, medical and biological procedures are carried out in the laboratories; this characteristic of laboratories makes it essential to use certain equipment to facilitate the activities carried out; one of these teams is the rotavaporador; which are used in different areas and institutions such as: chemical industry, pharmaceutical industry, laboratories and hospital sector; they are also used in the manufacture and analysis of experiments to concentrate, dry and recycle.
What is a Tunnel Effect Microscope?
A tunnel microscope (STM) is a device for capturing images of atomic surfaces. The tunneling microscope allows the use practices of the current of electrons that originates between a very fine preceptor tip and a conductive prototype, when they are placed very close and a potential is used between both. The image that is collected is the electronic density on the conductive surface allowing atomic order resolutions. The sensitivity of this type of microscope is very high because the current of electrons decreases exponentially with the separation or increase of distance between the tip and the surface to be observed.
What is a Confocal Microscope?
Within the laboratory, the use of microscopes is necessary for conducting biological research. Basically, it is the use of light sources, light detectors and other elements that prevent luminescence from planes other than the focus of the sample. Its use has spread in different fields of science, specifically in biomedical.
What are the steps to use and calibrate a meter?
It is important to follow the instructions and recommendations of manufacturers for the use and calibration of a phmeter, since, to achieve a correct measurement with a phmeter must be calibrated correctly, remember that the pH measures the concentration of hydrogen ions, which determine the degree of acidity and basicity of a solution; in addition not only works to measure the degree of water contamination, but as a diagnosis of body diseases or when measuring pH of urine and blood.
PH meter, water pH, milk pH, and human body pH
PH is a parameter used to measure the concentration of the hydrogen ion [H +] in a solution. In definition pH, it is the negative logarithm of base 10 of the activity of the [H +]. PH values vary on a scale from 0 to 14, which indicates the degree of acidity or alkalinity of an aqueous solution.
How do I use a laboratory pH meter?
A pH meter or pH meter is a laboratory instrument used to measure the acidity or alkalinity of a solution, perform a fairly accurate analysis on these fluids, this is done through polarizable glass plates sensitive to hydrogen ions.
Importance of pHmeter in a laboratory
A pH meter is one of the most used equipment in a laboratory. It is used to measure the acidity or alkalinity of a solution and the information it provides expresses the degree of acidity of an acid or base in terms of the activity of hydrogen ions, so through the use of this equipment we can know the type of substance we are analyzing, as well as the type of treatment that should be given to it
PH meter or pH meter: How should it be used?
A pH meter is an instrument used to measure the acidity or alkalinity of a solution. The information provided by this equipment expresses the degree of acidity of an acid or base in terms of the activity of hydrogen ions.
