Feature(may vary by option.)

●5 bottles of high purity, high density and high penetration CO2 cylinders (2.5 oz/40 L) for industrial use. To use, a regulator or adapter (such as gas injection nozzle, high pressure hose) is required to control gas pressure according to the application. High purity gas is sealed in a JIS standard container that adheres to regulators and seals of various materials, sizes and shapes to prevent leakage.

●The 74g/40L CO2 gas canister contains approximately 400 times higher purity of 99.99%, and 2000 ml impurity gases that are 500 times purity at 99.9%, and 95% purity. In general, the purity of the purity of the purity is less impurity and it has a higher permeability to solids and liquids, for example, in aquatic tanks, when combined with a light that can be irradiated to the bottom, photosynthesis will promote and lead to oxygen saturation
●Even if you get gas for a cheaper price, you may not get the effect you expect from a low purity. In addition, when the gas is leaked, the gas unit price will be greatly increased
●(Feature 1) Gas and Container (JIS Standard) are made in Japan for quality and stability and safety. (Feature 2) High purity and high density liquid carbon dioxide with very little impurities
●(Feature 3) Raised mouth design to seal with various gaskets to prevent gas leakage. High pressure gas varies. The higher the purity of the purity of the gas is generally the higher the price. Even if you get a gas cylinder at a cheaper price, a little gas leakage will pop up the unit price of the gas canister. Gas leaks will occur when installed easily and after hard to notice use (gas leakage due to loose screws due to lower internal pressure of the cylinder). The main cause of gas leakage is due to "tightening when attached", "quality of gasket", "shape of gas cylinder", and "nature of gasket" and "gasketing and gas cylinder". There are many types of packing bags in combination of material types (silicone, plastic, rubber), elasticity, thickness, and hole size. This product is designed with a raised mounting port to ensure a tight seal for a wide variety of gaskets
●(IMPORTANT #1) To use a regulator, gas injection nozzle or adapter depending on the application to control the gas output. The diameter of the cylinder is 5/8 18 UNF, size is 4 φ x 13 cm, material JIS G3141, surface treatment JIS H8610, container breaking pressure 50 - 90 MP. (Important Note 2) No instruction manual is included. Recommended for those who are used to handle inflators (regulators) and mini cylinders
●(Important Note 3) We will ship in very simple packaging to reduce the price. We cannot accept returns after shipment, so please kindly understand. (Important note 4) Since it is not applicable to the high pressure gas security law, handling such as inventory and disposal after use is relatively easy. After use, gas cylinders are discarded in many areas as metal waste (non-flammable). Garbage disposal rules vary in region, so please check in your region
