？ economic effect

- The only endoscopic disinfection device in Korea that follows the notice that hypochlorite should be generated and used at the site of use

- Most competitors use peracetic acid and hydrogen peroxide, which costs about 1,600 to 3,500 won per disinfection, while we use purified salt by electrolysis, so the cost per disinfection is low compared to existing products

- Where you use a recycled disinfectant, you should use a daily concentration check strip to check the effectiveness of the disinfectant, which is to be purchased separately from the disinfectant.

- OCTA-SELL is not subject to test strip use to generate and use new disinfectant each time

- Recycled disinfectant should be treated with medical waste along with used containers

- The more you use this medical waste as a progressive agent, the more expensive it is to throw away, but the disinfection solution is liquid, so the cost of medical waste is high

- In addition, we are selling additional subscriptions and leases to ease the burden on consumers, and there are no additional costs other than subscriptions and leases paid by consumers

？ hygienic effect

- Excellent efficacy of endoscopic scope disinfection enables eco-friendly disinfection devices that other companies have not implemented

- Hypochlorite produced by electrolysis of purified salt can be treated with sewage, so it can be treated immediately after the disinfection process, which is very effective in generating medical waste
