Why is a microplate washer important?
A microplate washer is a laboratory instrument used to perform washing operations during the ELISA technique. Washing is one of the crucial stages during the realization of the ELISA technique, because, to obtain the best results, i.e. the maximum relationship between the specific signal and the background signal, careful washing is essential.; special solutions are used, among the most used is the phosphate buffer solution or PBS.
How does electrophoresis work molecularly?
Functionally electrophoresis is a technique that consists of proportional migration of molecules through a gel or other type of porous matrix, depending on their molecular weight or size; movement generated by the electric field, i.e. we apply an electric current to molecules whether biological, DNA, protein or RNA, and they are separated according to whether they are larger or smaller.
Spectrophotometers: care and maintenance
A spectrophotometer is an instrument used in laboratories to measure the absorbance of a sample, as a function of the wavelength of an electromagnetic radiation, and thus to know the concentration of the substances in a solution. This team consists of 4 main parts: a source, a monochromator, a beam splitter, a sample area, and a detector. It also has optical elements such as lenses or mirrors, which transmit light throughout the entire equipment.
Importance of Recirculation Baths in a Laboratory
They are essential equipment in a laboratory, because they are used to contain water and with a fixed temperature that can be regulated; its importance lies in its use, since they allow to maintain a constant temperature while moving liquids; and according to the needs of the sample the recirculation baths can heat or cool the water; are the best solution for any application that requires placing multiple samples in a water bath, where it is necessary to ensure precise and effective temperature control directly from the samples submerged in the water, from the ambient temperature to 105 °C.
Why is a water bath essential in a laboratory?
This equipment has varied and indispensable applications in the laboratories, thanks to its hot water container, where samples are incubated in water at a continuous temperature over a long period of time, among other useful applications is heating reagents, fusion of substrates or incubation of cell cultures; because of its high temperatures it allows certain chemical reactions to occur, and heat flammable chemicals instead of an open flame to prevent ignition.
What is the pharadic effect?
The pharadic effect consists of neuromuscular stimulation when frequencies are applied below 100,000 Hz, which can generate an electric shock in the patient and become life-threatening. This occurs because the low or medium frequency alternating current causes stimulation in muscles and nerves, which can cause tetany, ventricular fibrillation, extrasystoles and even death.
How is phototherapy measured?
Phototherapy, is the treatment used to decrease bilirubin levels in neonates, based on photo degradation resulting in treatments under light UZ to easily depose. The effectiveness of the treatment will depend on the intensity of the light, regulated by filters of 400 and 550 nm, approaching as close as possible to the blue light. It also influences the intensity of the radiation, regulated by controls of light intensity towards the patient, taking into account the distance between the patient and the light.
How do I use a Turbidity Meter?
A turbidity meter is a laboratory device used to measure the turbidity of a liquid. This equipment has the property of measuring the size and concentration of particles in a suspension by diffusing light into a tube.
What is the optical surgical navitation function?
Computer-assisted surgery are methods of computer technology for the realization and planning of a surgical intervention. Optical surgical navigation is considered, the passage of computer surgery as a traditional basic element resulting in touch control, stereoscopic vision, manual dexterity and complete visual control of the surgical field.
How is an ultrasound scanner used?
An ultrasound scanner is a specialized medical device that uses ultrasonic waves, i.e. waves with frequencies above the human ear threshold (more than 20,000 cycles per second or 20 kHz) to obtain images of most soft tissues. This instrument provides diagnostic images from the echoes obtained by the emission of these waves.
