Toei Kaisha starts import and sales of high-quality, low-cost PETG culture bottles

Toei Kaisha (Chuo City, Tokyo) has begun importing and selling polyethylene terephthalate glycol (PETG) culture bottles, a new product of Tarsons Products (headquartered in India) of which Toei Kaisha is the sole import agent. This new product is primarily used for the storage and transportation of culture media, serums, buffers, reagents, and active pharmaceutical ingredients, offering the same quality as that of products made by major manufacturers but at a lower cost.

In addition to not using recycled resin, the product is made entirely from virgin resin that contains no animal-derived components, and has excellent purity because no additives, such as plasticizers, are used in the molding process. The resin also complies with USP Class VI testing, the US Pharmacopeia's conformity criteria for plastic containers used for pharmaceuticals and is manufactured entirely in a clean room. It is DNase-, RNase-, and pyrogen-free, as well as non-cytotoxic and non-mutagenic, and complies with biological test standards such as USP37 <661> and ISO10993-3. Because the bottles are gamma sterilized, there is no need for cleaning, depyrogenation, or other purification processes.

PETG has excellent sealing and gas barrier properties and can suppress the permeation of oxygen and carbon dioxide gases that cause changes in the pH of the content liquid, thus enabling strict storage of the content liquid. Unlike borosilicate glass bottles, PETG bottles do not break and are cost effective. The new product line is available in 10 sizes, ranging from a minimum of 5 mL to a maximum of 2 L. The 5 mL to 20 mL sizes are round, whereas the 30 mL to 2000 mL sizes are square. The square type is supplied shrink-wrapped at the neck to prevent contamination with impurities. The company pays close attention to quality and expects demand mainly from the pharmaceutical and biotech industries.
