CO2 Regulator System

CO2 Regulator System

The CO2 Regulator System provides fast, safe delivery of carbon dioxide for a variety of purposes. The system consists of a new, aluminum Type E cylinder filled with ULTRA HIGH PURITY USP Carbon Dioxide with a Minimum purity of 99.99%. A research grade high purity CO2 regulator with a stainless steel diaphragm preset at 25 psi., a push-button operated safety fill valve, a male Luer lock fitting, submicron sterile hydrophobic filters, and a cylinder cart.

System purity begins with the new aluminum CO2 cylinder. Aluminum is non-corrosive and not subject to interior rust, a condition common to steel cylinders. Since CMD supplies a new cylinder, there is no danger of the cylinder having previously been contaminated by other industrial gases, moisture, etc. Each individual CO2 cylinder is analyzed by mass chromatography to ensure purity. A certificate of analysis is supplied with each cylinder.

The regulator is a high purity research grade gas regulator intended for primary pressure control of high purity no corrosive, research gases. Each regulator has been set at 25 psi. to ensure a proper gas flow rate.

We offer the regulators with ether a CGA320 nut cylinder connection or a medical CGA940 yoke cylinder connection. The preset regulator has one gage that shows pressure of the cylinder and is preset to 25 psi.. The adjustable regulator has two gauges, which indicates pressure in the cylinder and the set pressure. The regulator pressure is adjustable 0 to 40psi.

All cylinders purchased from CMD, Inc. are new aluminum type E cylinders. Cylinders come with a CGA320 diaphragm valves for use of ultra pure grades of CO2, All cylinders are individually tested to insure purity and certificate of analysis are provided. A full cylinder of carbon dioxide will read about 840 psi. . Full cylinders contain approximately 1.3 million cc of CO2. A refill should generally be ordered when the cylinder reaches approximately 600 psi. When you order a refill you simply put your empty exchange cylinder in the box that the refill came in, and place the provided UPS return labels on the shipping box and take it to your shipping /receiving department.

Used cylinders are supplied only when a customer requests a refill rather than purchasing a new cylinder, and have only been filled with high purity USP Co2. Many facilities purchase an additional cylinder initially to ensure always having a gas supply. We now offer a second cylinder at a reduced cost.

On the low pressure end of the system is a push button fill valve. This push-button must be manually depressed to release the gas flow. This is a safety feature designed to prevent the user from opening the cylinder valve to release gas flow, and then neglecting to turn it off quickly enough to prevent waste, or even overflowing or bursting whatever device is being filled with the CO2. Additionally, the use of this valve allows the user to more precisely deliver the amount of CO2 desired.

The final components of the system are the luer lock fitting and sterile submicron filters. The luer lock fittings are standard catheter/syringe type components, and are available in either male or female connections, with male being standard on the system. Screwing onto the luer fitting is a .2-micron filter, which also has a dual luer connection. Although purity of gas flow is assured throughout the system, the filter provides a sterile barrier. 25 individually blister packed, sterile filters are included with the system. The filters and the CO2 itself are the only disposable components of the system.

The CO2 Regulator, has been carefully put together, to provide the user with maximum assurances of safety, as well as ease of operation. The user can rest assured that the CO2 flow from the low-pressure end of the regulator passing through the filter is of the same purity as the gas in the cylinder. Any operator will be able to set up this system and have it operational in minutes.

Standard USP Carbon Dioxide only has to have a Minimum Purity of 99.0%. Only one cylinder per batch of cylinder filed has to be tested for minimum requirement to be USP Carbon Dioxide

Every cylinder we stock is filled with USP Carbon Dioxide and has been individually analyzed and provided with its certificate of analysis. With a minimum purity of 99.99%
