Injection refers to sterile solutions (including emulsions and suspensions) made from drugs, as well as sterile powders prepared into solutions or suspensions before use.

Eye drops have strict filtration requirements. Some eye drops have high viscosity and are very difficult to filter. Some eye drops contain very low level of preservatives and are easily adsorbed by normal cartridge filters.

Cobetter provide a comprehensive filtration solution from raw material extraction to injection, including depth filters, nanofiber PP filters and absolute-rating PES filters.
