    ASSEMBLY The following instructions are to install the 40K cell. Use the exploded diagrams in Figures 11 and 12 to reference the parts of the cell. Please take careful note of the precautions as they can prevent future damage to the cell. Only the PC-435 o-ring style flow valve assembly can be used to 40,000 psi PRECAUTION: For the 40K, the valve should be finger tight.
  • Page 21 Verify the contents of the package with the parts list. PRECAUTION: It is imperative to protect the piston from foreign matter at all times. Collected granules (e.g., sand, glass, dirt, etc.) will irreversibly damage the cell. Figure 13 The 40K cell in filling position Assemble the Cell Table Stand (see Figure 13).

  • Page 22: Installation

    NOTE: The tube may be bent to accommodate sample flow. Note that excessive bending may break the tube. Simultaneously push and rotate the piston into the opening at the top of the cell. There may be some resistance to pushing in the piston. Simultaneously push and rotate the closure plug into the opening at the bottom of the cell.

  • Page 23: Operation

    OPERATION Figure 14 Rod extensions for the 40K Cell Position the piston for the amount of sample you want to process. Do not, however, withdraw the piston further than the top MAX FILL. If you do, you could cause the piston and cell body to misalign and damage each other.
  • Page 24 PRECAUTION: The aligning pins, on the lower platen of the FRENCH Pressure Cell press, center the cell directly above the pressure actuating cylinder. Forces other than in a straight line through the cell cause scoring of the piston and possible damage to the inner wall of the cell body. Be sure the cell clamp of the laboratory press is properly and securely fastened to ensure that the cell cannot escape the press if improperly positioned or overpressurized.

  • Page 26 Loosely install the liquid inlet valve onto the valve mounting bracket using the two ½-20 hex head screws, lockwashers and the retaining plate. The valve needs to be loose to properly fit the tubing into the liquid inlet valve. Install the closure plug in the bottom of the cell body. Remove the high pressure plug (gland nut/plug) from the rear of the closure plug.

  • Page 27: Installation

    INSTALLATION Remove the cell clamp support rods from the lower platen on the press and install the two support rod extensions. Replace the support rods by attaching them to the rod extensions. Place the cell on the lower platen between the aligning pins. Secure in place with the press cell clamp.

  • Page 28: Operation

    OPERATION Install the rapid-fill pressure cell in the press. See the 40K cell installation section in this chapter. Be sure the cell clamp on the laboratory press is properly fastened to ensure that the cell cannot escape the press if improperly positioned or over-pressurized. Lower the platen by placing the three-position control lever to DOWN.
  • Page 29 WARNING: DO NOT OVERPRESSURIZE. BEFORE APPLYING PRESSURE TO THE CELL, DETERMINE THE GAUGE PRESSURE REQUIRED TO PRODUCE THE DESIRED PRESSURE IN THE CELL. IF THE MAXIMUM WORKING PRESSURE OF THE CELL IS EXCEEDED, THE SEALS AND/OR THE CELL ITSELF COULD RUPTURE CAUSING INJURY TO THE OPERATOR (SEE FIGURES 8 &...

    ASSEMBLY The following instructions are to assemble the min-cell. Use the exploded diagram (Figure 17) to reference the parts. Please take careful note of the precautions as they can prevent future damage to the cell. Verify the contents of the package with the parts list. PRECAUTION: It is imperative to protect the piston from foreign matter at all times.

  • Page 32: Installation

    INSTALLATION Place the mini-cell spacer between the aligning pins on the press platen. PRECAUTION: It is imperative to protect the piston from foreign matter at all times. Collected granules (e.g., sand, glass, dirt, etc.) will irreversibly damage the inside of the cell. Place the assembled mini-cell on the spacer using the pins on the spacer as a guide.
  • Page 33 Holding the closure plug tightly against the cell body, invert the cell to its normal position and place in a press, carefully centering it on the press platen. WARNING: THE AREA OF THE CELL PISTON IS 0.11 OF AN INCH; THEREFORE, ONLY 2,200 LBS OF COMPRESSIVE FORCE ON THE PISTON CREATES 20,000 PSI (MAXIMUM WORKING PRESSURE) IN THE CELL.

  • Page 37: The French Pressure Cells

    THE FRENCH PRESSURE CELLS DO NOT STORE THE PRESSURE CELLS ASSEMBLED. Clean and dry the pressure cells thoroughly after each use. Components can be autoclaved if required. All metal parts are made of 400-series stainless steel (specially heat-treated) and are susceptible to surface corrosion if not properly cleaned and dried. A light coating of mineral oil should be applied to all surfaces to prevent corrosion during periods of non-use.

    THE RAPID FILL KIT DISASSEMBLING AND CLEANING THE RAPID-FILL KIT Disconnect all tubing and remove the flow valve assembly from the Rapid-Fill Kit. Figure 18 Remove screw from the bracket that encircles the large nut at the base of the flow valve handle (see figure 18).
  • Page 41 When the threads of the large nut are clear, firmly but gently pull the handle and stem straight out. NOTE: DO NOT WIGGLE THE HANDLE ASSEMBLY IF THE ASSEMBLY IS TOO TIGHT TO REMOVE EASILY! This is designed to handle high pressures without leakage, and therefore, has very tight tolerances.
  • Page 42 REASSEMBLING THE RAPID-FILL KIT Ensure that the handle is turned completely counterclockwise. Holding the handle and the large nut, gently insert the stem into the body of the valve (see Figures 19-23). (Make sure that the bracket is in place). Manually rotate the handle and the large nut clockwise until the nut is hand-tight.
