Matheson has
99 Gas Regulators Engineered for your specific requirements Specialty Gas Handling Equipment is our business. To handle a gas properly you must have the proper regulating device. Matheson has 99 engineered regulators, each for a specific use. For example:
Corrosion Resistant
General Purpose These regulators have earned their excellent reputation in many years of dependable ser vice. They are basic regulators suitable for most laboratory applications. Available in two stage (Series8and9) and single stage (Series 1) models; they provide accurate, stable de livery pressures, and excellent no-flow shut-off capabilities. Delivery pressure ranges of 2-15, 4-50, 10-100, and 20-250 psi are available.
Models 11 through 16. The Matheson Catalog lists 21 regulators to handle, specific corro sive gases. Our Models 11-14 are designed to withstand gases that attack copper bearing alloys. They have an anodized aluminum body, with AISI 316 internal parts and inert plastics for diaphragm and seat surfaces. Our Models 15 and 16 for acid forming gases (e.g. halo gens) have a chemically coated nickel body with internal parts of Monel, Kel-F, and Tef lon, with a seat closure for added safety should minor corrosion develop. Delivery pressure ranges of 4-35, 4-50, 4-60 and 50650 psi are available. CIRCLE 1 4 4

High Purity
These versatile regulators are used to elimi nate pressure fluctuations in plant lines or to provide pressure control at selected stations. Their large diaphragm areas provide sensi tive, accurate low pressure control. Some models can be adopted for use on low pres sure gases in cylinders. In all we have 13 regulators in a variety of pressure ranges and construction materials. Delivery pressure ranges of 2"-12" of water, 0.5-5, 0.5-8, 5-10, 5-12, 0-20, 4-25, 4-90, 5-100, and 20-200 psi are available.
Designed for the most exacting applications. These regulators prevent the diffusion of at mospheric gases into your system. They have metal diaphragms to eliminate out-gassing of hydrocarbon type compounds. Of our 18 high purity regulators, nine are all stainless steel; nine are brass. All of them can pass a 5 min ute helium leak rate test of < 2 χ 10-'° ces. Series 3800, 3500, 3100, 19, 3451. Delivery pressure ranges of 0-15, 0-20, 0-25, 4-50, 0-75, 4-90, 4-100 and 10-150 psi are available. CIRCLE 147

Vacuum Regulator
Lecture Bottle Regulators Matheson created the lecture bottle. These regulators were specificalty engineered for use with lecture bottles. They can also be fitted with standard CGA connections for use on larger cylinders. With 3 models for noncorrosive service and 7 for corrosive gases, there is a model for your application. Delivery pressure ranges of 0-18" of water, 1-6, 2-15 and 4-60 psi are available.
This vacuum regulator allows gas to bleed into a system under constant evacuation to maintain a desired vacuum (2-655 torr.). Maxi mum inlet pressure 50 psig. Use it with air or any non-corrosive gas. We have not found the vacuum pump that can beat our regulator.

Custom Engineered Some requirements cannot be met by standard regulators. Matheson will review your needs and modify a standard regulator or develop a new one to suit your purpose. Pre-set de livery pressure, tamper-proof adjustments, and special characteristics are only a sample of what we can do. Send us your specifications today.
