Microscopes – types of condensers
The microscope is an instrument that increases the size of an image and allows you to see more details than would be possible to perceive with the naked eye. The condenser of a microscope is a key part of a microscope, it focuses the light that passes through the stage of the microscope where the sample is placed, thus providing illumination, contrast and clarity in a uniform way to the sample.
Electrophoresis: steps for a run of gels
Electrophoresis is a molecular biology technique where controlled electric current is used to separate biomolecules according to their size-to-electric charge ratio, using a gelatinous matrix (gel) as a base.
What is a laboratory magnetic stirrer?
A magnetic stirrer is laboratory equipment that uses a rotating magnetic field to mix one or more solutes with a solvent in an automated way. It is considered the most widely used type of stirrer, since it is silent, efficient and does not have direct contact with the sample.
Thermal Cycler Protocols (PCR)
A thermal cycler is a laboratory equipment that allows to carry out the polymerase chain reaction (PCR) efficiently and quickly, by means of the automatic and cyclical realization of the temperature changes that are required for the amplification of a chain. deoxyribonucleic acid (DNA), from a thermostable enzyme. PCR enables a small number of DNA molecules to be amplified many times, exponentially.
What is a BOD incubator?
A BOD (Biodemand Oxygen) incubator is a laboratory incubator used with the objective of maintaining the appropriate temperature for the growth of cell cultures, storage of bacterial cultures and the types of incubation where a high degree of temperature precision is needed.
Importance of the photo documentation in molecular biology
The photograph has played a decisive role in the history of science. Since its inception, it has become a powerful research tool, education and disclosure of science in all its branches. Through the record of images of different technological instruments it has been possible to represent and analyze many results product of years of research.
Types of warming blankets
The heating blanket is a laboratory equipment used mainly in chemistry and biology laboratories, whose main function is to apply heat, evenly, to several containers with samples inside. This equipment is designed for use with difficult to position flasks and funnels and offers an alternative to thermoregulated baths.
Features and care of a laboratory ovens
The ovens are composed of two chambers: an internal and an external one. The outer chamber is made of steel sheet, covered with an electrostatic protective film. The internal chamber is usually made of aluminum or stainless material to better transmit heat; It has a set of shelves or shelves manufactured in stainless steel wire, so that air circulates freely, there are placed the elements that require dried or sterilized by dry heat. It is isolated from the outer chamber by an insulating material that maintains the high temperature conditions internally and delays the heat transfer abroad.
What is a magnetic stirrer used for?
A magnetic stirrer is a laboratory equipment that uses the force of the magnetic field produced by a magnet, which generates a vortex in the solutions with the help of a magnetic bar, at the rate of the rotating magnetic field. In many cases, a shaker is essential for laboratory research and testing that requires mixing, shaking, or pooling solutions.
Recirculation Cooler: How Does It Work?
Chillers are used in many laboratories for a wide variety of important purposes, from improving the precision of experiments to improving the safety of laboratory personnel. They are teams with many uses and important benefits. Depending on the needs of the laboratory, there are different types of chillers that can be used. In this article, we will focus on recirculating coolers.
