Sample Tube

Metal FlowThru tubes*

For use up to 850 ºC, 316 SS,

Sample size. 0.3 inches diameter (7.5 mm) by 1.5 inches (40 mm)

Material. Up to 1000 psia

Fused quartz FlowThru tubes

For use up to 1100 ºC

Sample size. Powders and pellets up to 9 mm in diameter

Material. Atmospheric pressure only

*   Published material specifications, which include design safety factors, limit these tubes to 650 ºC and 1000 psia. However, extensive testing at 850 ºC and 1000 psia of numerous tubes of identical design and material have resulted in no failures. Additionally, as a safety measure, the tube in operation is enclosed in a clam-shell furnace. The furnace incorporates a limit switch which cuts the current and releases the pressure if opened to the point of switch actuation. Reactive gases and reaction products, the nature of which cannot be anticipated by Micromeritics, can corrode or embrittle any steel. The user is advised to examine each tube after use and discard any that might appear questionable. It is also essential for maximum safety that, whenever tubes are at elevated pressure even at ambient temperature, the furnace be in place and closed should a failure occur.

Temperature System
Range

Standard pressure (up to slightly above atmospheric pressure) in quartz sample tubes:

  • -100 to 1100 ºC (with optional CryoCooler)
  • Ambient to 1100 ºC (without CryoCooler)


High Pressure (up to 1000 psia) in stainless steel sample tubes:

  • -100 to 850 ºC (with optional CryoCooler)
  • Ambient to 850 ºC (without CryoCooler)
Selection Digitally set, 1 °C increments
Ramp rates Up to 50 °C per minute within -70 to 500 °C range
Up to 30 °C per minute within 500 to 750 °C range
Up to 10 °C per minute within 750 to 1100 °C range

Wetted Materials

Standard System

  • Stainless steel
  • Gold plated nickel/iron (filaments)
  • Kalrez® or Chemraz® (most O-ring seals)
  • Quartz (sample tubes, thermocouple sheath)
  • Quartz wool (supports sample in tube)
  • Inconel® - sheathed sample thermocouple (can be placed outside tube or sheathed in quartz)
  • PEEK (Poly Ether Ether Ketone - some ferrules)
  • Teflon® tubing (most exhaust lines); TCD exhaust is stainless steel for connection of external devices
  • Copper (gas supply lines and BET delay path)
  • Nickel plated brass and steel (gas inlet valves)
  • Viton® (seals inside mass flow controllers)
  • Polyaryletherketone/PTFE composite (rotary valves seals)
  • Silicone/Teflon sandwich (septum)

System with Enhanced Chemical Resistant Option

Same as standard system except stainless steel manifolds are protected from corrosion with vapor deposited Silcolloy by Silcotek®, Stainless-steel tubing, fittings, ferrules and rotary valves are replaced by Hastelloy-C® versions, Kalrez is used for all O-ring seals and the seals inside the mass flow controllers, stainless-steel grade 316 gas supply lines, stainless-steel gas inlet valves with Kalrez or Chemraz seals.

Computer Requirements

  • Operating System. Windows 7 Professional or higher operating system is recommended for the best user experience.
  • Desktop Installation Required. The application should not be installed on a network drive with shared access. Multiple users cannot operate the application at the same time.
  • 10 Base T or 100 Base T Ethernet Port. If the computer is to be connected to a network, two Ethernet ports are required. If more than one Ethernet based unit is connected to the same computer, an Ethernet switch will also be required.
  • Read / Write Permissions.  All users of the application will need Read/Write permission to all directories and subdirectories where the application is installed.
  • Drives. CD-ROM drive and thumb drive.

In keeping with a policy of ongoing product improvement, specifications are subject to change without notice.
