ChromaBLOGraphy: How do I order a dip tube?

  A dip tube (also known as an outage tube) provides vapor space above liquefied gases in a sampling cylinder so that if expansion occurs with an increase in temperature, the pressure is not significantly increased. Basically, the length of the dip tube is used to determine the filling capacity of the cylinder. Outage is expressed as […]
