In cell culture, contamination is a 'stumbling block' for scientific researchers - ultra-clean bench disinfection, aseptic operations, and expensive culture media and serum are all available, but the cells are still in poor condition, the data is biased, and the entire batch is even scrapped. Most people only check the operations and reagents, but ignore the key 'invisible killer' - contaminated experimental consumables.

core background
As the direct 'home' of cells, details such as sterilization, endotoxins, surface treatment, production environment and materials may all be sources of pollution. Today we dismantle these overlooked details to help you avoid risks from the source.
Cell culture contamination can easily lead to data deviation or cell scrapping. Traditional inspections focus more on operating specifications and reagent quality, but often ignore the risks of consumables. As the direct carrier of cell growth, the quality of consumables is a key link in pollution prevention and control and needs to be strictly controlled from multiple details.

Key details of the four major consumables and Aijin’s plan
1
Sterility guarantee: more than 'irradiation', the key is the level of sterilization
The core of the problem:
Different sterilization methods (steam, EO, radiation, low temperature) have their own advantages and disadvantages. Incomplete sterilization or residual sterilization may cause contamination.
Aijin plan:
Using radiation sterilization, the sterility assurance level (SAL) reaches 10⁻⁶, that is, the probability of microbial survival does not exceed one in a million, which meets high quality standards.
2
Endotoxin Prevention and Control: Beware of Invisible 'Cell Killers'
The core of the problem:
Endotoxins (lipopolysaccharide from Gram-negative bacteria) are difficult to remove and will activate immune responses, damage the culture environment, lead to cell growth retardation and apoptosis, especially affecting sensitive cells.
Aijin plan:
Strictly control the endotoxin content of consumables to ensure no residue and provide a clean and stable growth environment for cells.
3
Surface treatment: In addition to smooth, it needs to match the cell type
The core of the problem:
Rough surfaces tend to harbor dirt and evil, and different cell types (adherent/suspended) have different surface treatment requirements. Adherent cells require TC treatment (introducing hydrophilic factors) to adhere and grow.
Aijin plan:
Except for the triangular culture shake flask, all other cell experiment consumables are available in TC-treated and untreated types to adapt to different culture needs.
4
Production environment and materials: eliminate pollution from the source
The core of the problem:
Low cleanliness of the production environment and insufficient purity of raw materials can easily lead to secondary contamination of consumables or initial defects.
Aijin plan:
It has a 26,000m² base and has passed ISO13485 and other certifications; it is equipped with 5,500m² 100,000-level and 500m² 10,000-level dust-free workshops; the raw materials are USP VI medical grade PS (medical PC for triangular shake flasks), ensuring cleanliness from the source.
