Freeze dryers in pharmaceutical companies
Freeze drying has become a standard practice in the pharmaceutical industry, since the beginning of its first applications around the 40’s. Since then, the freeze dryer has gone from being a simple vacuum drying equipment to become a highly sophisticated system and integrated, which combines a series of processes to guarantee a systematic production according to technical and biological specifications.
Laboratory freezers at Kalstein
Freezers are refrigeration equipment that is composed of a thermally insulated compartment, which allows it to keep cold and thus avoid damage or degradation of substances. These equipments maintain the cold by compression or by absorption, being able to maintain temperatures below 0 ° C, usually between -30 ° C and -4 ° C, although more modern frerzers can reach temperatures of -80 ° C .
Kalstein Turbidimeters
Turbidimeters are equipment that through optical analysis measure the turbidity of a liquid. That is, they are devices capable of measuring the size and concentration of particles in a suspension by diffusing light at 90 ° in a tube. It can be portable or fixed.
What are the types of homogenizers?
There are many models of laboratory homogenizers on the market. Below we will show you different models, tips and information so that your homogenizer is the most suitable for your processes and you feel satisfied with your purchase.
What is a laboratory water bath?
A water bath is laboratory equipment that is designed with a container filled with hot water. This equipment is used to incubate samples in water at a constant temperature for a long period of time. Among its uses we have the heating of reagents, fusion of substrates or incubation of cell cultures.
Turbidimeter – Units of Measurement
A turbidimeter is a laboratory device used to measure the turbidity of a liquid. These equipments can also establish the size and concentration of the particles that are placed in suspension through the diffusion of light in a tube.
What is a recirculation bath?
A recirculating bath is ideal laboratory equipment for any application that requires the placement of multiple samples in a water bath. They are useful equipment when a constant and reliable temperature is necessary, since they move the liquids while providing the set temperature. For example, in microbiological research, continuous shaking will allow cell cultures growing in the liquid to mix with air.
Vortex types: volumes
A vortex is a device commonly used in laboratories to mix small vials of liquid. It consists of an electric motor with a vertically oriented drive shaft attached to a slightly mounted recessed rubber part. It is an ideal instrument for gently mixing and forceful resuspension of cells and components of chemical and biological liquids in tubes using an eccentric mechanism.
Hyponatremia in primary care
Hyponatremia is the most frequently observed electrolyte abnormality; its mild form is associated with cognitive deficit and falls, but in hospitalized patients it is associated with increased mortality.
Acute adrenal insufficiency
It is a life-threatening episode that continues to occur despite preventive interventions. New solutions are needed for this problem. The survival of patients with acute adrenal insufficiency, also called the Addisonian crisis, was prolonged as of the year 1950 by means of glucocorticoid replacement therapy. However, many patients still suffer episodes of acute adrenal insufficiency, which are life-threatening emergencies. These events seem to be on the rise despite preventive strategies.
