Applications of Peristaltic Pumps in the Laboratory

Peristaltic pumps from Golander offer a host of advantages, including minimal shear force, high transmission accuracy, exceptional cleanliness, and unwavering performance. As a result, they stand as trusted allies in the laboratory, assisting researchers in achieving their scientific goals with precision and confidence.

Let's uncover the various pivotal roles that peristaltic pumps can effectively undertake.

Chromatography

Chromatography stands as a cornerstone in mixture separation technology, finding widespread use in analytical chemistry, organic chemistry, biochemistry, and beyond. It serves diverse purposes, such as determining protein molecular weights, facilitating protein separation and purification, as well as assessing polysaccharide molecular weights and their separation and purification.

In chromatography, the fluid's permeation rate within the chromatographic column often necessitates the application of external pressure to enhance liquid flow. Concurrently, it is imperative to maintain a contamination-free liquid transport process. Here, the Golander peristaltic pump comes into play, providing precise fluid pressure to facilitate the smooth passage of liquid through high-resistance chromatography columns. These pumps ensure the necessary flow accuracy for achieving desired chromatographic outcomes. Moreover, their low shear force minimizes the potential damage to active components in large molecule solutions like proteins.

Culture Medium Handling

Culture medium, a nutrient-rich matrix supporting the growth and reproduction of microorganisms, plants, or animals (including tissues), requires meticulous preparation and precise measurements. This medium serves as the foundation for cell nutrition, proliferation, and a conducive environment for cellular growth.

Golander peristaltic pumps excel in meeting the exacting demands of culture medium handling in laboratories. They offer precision, making them indispensable not only in medium production but also for tasks like medium sampling and packaging. These pumps boast a wide flow range and exceptional transmission accuracy. Additionally, they feature time-related functions such as timed measurement, allocation of specific intervals, and timed start-stop capabilities. When transporting culture medium, the medium only comes into contact with the hose, ensuring that the liquid remains untainted by the pump body, resulting in a higher cleanliness standard.

Tissue Perfusion

Tissue perfusion represents a critical experimental technique employed by medical colleges and research institutions for pharmacological and physiological studies. For instance, in the examination of neuronal distribution within isolated brain tissue, a continuous supply of oxygen-containing culture medium to isolated tissues or organs is imperative to maintain their physiological activity.

In vitro tissues or organs rely on the delivery of external nutrient solutions to sustain their vitality. Golander peristaltic pumps allow precise adjustment of the flow rate and total delivery volume, guaranteeing a continuous supply of nutrients to the perfusion tank, thereby ensuring the well-being of tissues or organs during experimentation. Simultaneously, these pumps efficiently remove waste liquid from the perfusion tank, maintaining optimal nutrient solution levels. Thanks to their reliable quality and stable performance, Golander peristaltic pumps facilitate swift fluid replacement in the perfusion tank, preserving the physiological integrity of isolated tissues and organs and facilitating seamless experimental progress.
