2024-08-21

Cell culture, as an important technical means in the fields of bioengineering, biomedicine and other fields, is widely used in scientific research, drug research and development, clinical treatment and other aspects. With the rapid development of biotechnology, higher requirements have been put forward for cell culture technology. Traditional cell culture methods have certain limitations in terms of operation complexity, production scale and cost control. In recent years, wave bioreactor technology, as a new type of cell culture technology, has gradually received widespread attention. In this paper, wave bioreactor technology and its application in cell culture field will be introduced in detail.



Overview

1. Principle of the technology

The Wave Bioreactor technology is a cell culture technology based on wave agitation. The technology is based on the installation of a wave agitator at the bottom of the culture vessel, which creates a wave-like flow of the culture solution, thus realizing a thorough mixing of cells and nutrients. Compared with traditional stirred bioreactors, Wave Bioreactor has the following advantages:

(1) gentle stirring process with little damage to cells;

(2) high oxygen mass transfer efficiency, which is favorable to cell growth;

(3) Small footprint, convenient for laboratory and industrialized production;

(4) Simple operation, high degree of automation.


2. Composition of the equipment

mainly consists of the following parts:

(1) Culture vessel: generally disposable, made of plastic or glass;

(2) Wave stirrer: located at the bottom of the vessel, responsible for generating wave-like flow;

(3) Control system: including temperature, pH, dissolved oxygen and other parameters monitoring and regulation;

(4) Gas supply system: to provide the necessary oxygen and carbon dioxide for cell growth.


Applications in the field of cell cultivation
