One-Timer Disposable Cylinders
We realize there are situations where a refillable cylinder may not be feasible, therefore we provide a line of disposable calibration type cylinders called One-Timers.

One-Timers are available in various sizes. We offer a 17 liter and 29 liter CGA-600 steel cylinder along with a 105 liter C-10 version. The aluminum 29 liter and 58 liter cylinders are offered for reactive blends with a C-10 valve connection.

One-Timers are perfect for all your calibration applications.

These designs cover a broad range of applications from industrial hygiene to petrol chemical. One-Timers provide outstanding quality, performance and value. One-Timers eliminate cylinder rental and demurrage charges, plus the added portability of these cylinders makes them perfect for specific small jobs. With the proven stability of our products, improper positive monitor readings are eliminated. Accuracy and dependability are what One-Timers deliver.

Calibration gas regulators are for use with disposable cylinders. These regulators are designed for non-corrosive gas service and are single state, piston style regulators. The control valve permits constant gas flow and easy on/off.

Each regulator comes with a cylinder pressure gauge and is available in four preset flow models. This series of regulators is recommended for use with disposable cylinders of non-corrosive gas using a CGA 600 valve.

CGA 600 Features

  • Piston type construction
  • Preset flow ratings
  • On/off valve
  • 1 1/2" x 700 psig gauge

CGA 600 Specifications

  • Maximum Inlet Pressure - 500 psig
  • Outlet flow settings
  • 0.25 LPM
  • 0.50 LPM
  • 1.00 LPM
  • 1.50 LPM
  • Inlet fitting - CGA 600
  • Outlet fitting - 3/16" hose barb
  • Temperature Operating Range - 0-140o F (17oC to -60oC)

Materials of Construction

  • Body - Brass Bar Stock
  • Spring housing cap - Chrome-plated brass bar stock
  • Seat - Teflon
