Laboratory Hoods: Differences
Laboratory hoods are fundamental pieces in the operation of this space to maintain air quality. The variety of hoods in the industry responds to the needs of scientists. Laminar flow hoods, biological safety hoods, and fume hoods all serve a purpose.
Differences between analytical and electronic balances
Balances are instruments whose purpose is to measure masses of bodies in greater or lesser quantity. They are characterized by their accuracy, their precision and their sensitivity. The first quality refers to the property that any physical instrument possesses to supply the result of a measurement with a value coinciding with the true one; this implies that the error is as small as possible. The term accuracy is often taken to mean precision.
How does a phase contrast microscope work?
The phase contrast microscope is a type of microscope that allows you to observe live samples without using staining techniques. This microscope is based on the existence of a phase difference between the different light waves that pass through the sample to generate the image of the observation.
How to use an analytical balance correctly?
The balance is a piece of equipment that measures the mass of a specific body, providing accurate data about its weight. Among the many existing models, the analytical balance that has a high power of rigor stands out, since with it great precision can be obtained.
Types of balances in the laboratory
The most common types of laboratory balances and scales are ultramicrobalances, microbalances, semi-microbalances, analytical balances, and precision balances.
Applications of Autoclave N, S and B
An autoclave is a piece of equipment that uses a combination of high pressure and steam in order to transfer heat to the items placed inside it. This device is made up of a thick-walled metal container and hermetic closure, which allows high pressure sterilization. , ensuring maximum disinfection of all clinical materials.
Processes for water purification
At present there are several equipment for the treatment and filtration of water. The choice of the most suitable one depends on the user’s need, since each one will leave the water adequate for different uses and processes.
What Biosecurity cabinet choose to work with COVID-19?
The biological safety cabinet represents a primary containment barrier that allows working safely with biological agents such as the virus that causes COVID-19. It is equipment designed to prevent the escape of bioaerosols from the work area and, therefore, protects people and the environment from possible exposure to these agents. There are three types, known as: class I, class II and class III.
What is a water purifier?
A water purifier is an equipment or device that removes (eliminates) the impurities present in the water, consider that, for the most part, this dirt is invisible to the human eye. In other words, we can say that water purifiers aim to eliminate impurities and organic and inorganic elements such as germs, bacteria and metals.
What is a microtome for?
Microtomy is the discipline that deals with obtaining fine serial sections from tissues included in paraffin blocks for their subsequent study under optical and / or electronic microscopy, which makes it one of the basic pillars of procedural techniques of Pathological anatomy.
