Pre-Clean & Sterilization
Pre-cleaned products have the high needs in various industries, such as semiconductor, medicine and pharma, etc.
Pre-clean plastic containers with pure water, acid and pyrogen-free water and remove particles(※1), trace metal ion and pyrogen attached to containers. After cleaning in clean rooms below class 1000, they are specially double-packaged.
※1:Fine dust and powder dust
Pure Water Cleaning
Separate the foreign materials from the plastic container with ultrasonic vibration and wash it off with pure water. It can remove particles attached to the containers.
We wash the plastic containers with acid such as hydrochloric acid, nitric acid, or hydrofluoric acid to remove particles, metal ions, fats and oils that adhere to the surface of the containers.
Cleaning with Pyrogen-Free Water
We wash the plastic containers with pyrogen-free water (※2) to remove pyrogen (※3) and particles that adhere to the container surface. Materials that cannot be sterilized by electron beam sterilization, gamma-ray sterilization, or autoclaving can also become pyrogen-free. Also, it is double packaged, so it can be brought into CPC facility (※4).
(※2) Washing water that meets the endotoxin standard 0.002EU/ml (actual value)
(※3) Pyrogen: a generic name for substances that cause a temperature increase in the body.
(※4) Cleanroom in cell processing center
We are pleased to receive any cleaning requests with pure water, acid and pyrogen-free water to bottle, beaker and tube,etc. We will suggest the optimal cleaning method according to intended use.
We sterilize the plastic containers with electron beam or EOG (Ethylene oxide gas). The sterilized products are used in a wide range of fields, including the food field, medical field, sample containers for water quality analysis, and cosmetic containers.
Electron Beam (EB) Sterilization
Electron beams are highly permeable, allowing internal objects to be sterilized while still in the package. It is commonly used for medical devices, pharmaceutical containers, drinking water containers, and culture-related consumables. Electron beam irradiation is a high-throughput sterilization method that produces no harmful residues.
This is a low-temperature sterilization method using EOGs (Ethylene oxide gas). The residual chlorine gas after sterilization treatment can be safely used by properly degassing. Gamma-ray, electron-beam, and autoclave sterilization may denature or deform the material. However, EOG sterilization, which is low-temperature sterilization, has little effect on the material.
