  • Page 4: Important Notice

    Important Notice Please check that your Linkam equipment has not been damaged during transit. If there is any evidence of external damage DO NOT SWITCH ON ANY ELECTRICAL ITEMS. Contact LINKAM SCIENTIFIC or their appointed distributor immediately. Your warranty may be impaired if Linkam is not informed of any transport damage within 7 working days of delivery.

  • Page 5: Safety Precautions

    Safety Precautions 1) Read this guide before using the equipment. Save these instructions for later use. 2) Follow all warnings and instructions which may be placed on the stage. 3) Never use the equipment if any cables have been damaged. Do not allow any heavy objects to rest on the cables.

  • Page 6: Introduction

    Aperture hole: 1.3mm Weight: 0.6Kg FDCS196 System The system consists of a FDCS196 stage, a T95- LinkPad System Controller, LNP95 liquid nitro- gen cooling pump system, Pirani vacuum gauge and LINK software. The FDCS196 Pro System has an additional 1.5L Vacuum Pump and MV196 motorised vacuum valve control System.

  • Page 8: Mounting Stage To Microscope With Dovetail Substage

    Mounting Stage to Microscope with Dovetail Substage The following description is for mounting the stage on to microscopes which have a circular dovetail substage assembly. Attach the curved stage clamps (part no. 9542) to the base of the stage using the supplied hex screws and the outer most holes in the base plate.

  • Page 9: Vacuum Tweezers

    Vacuum Tweezers The vacuum tweezers are used to manipulate the glass sample slides onto the silver block to prevent fingerprints on the glass and scratching the surface of the silver block when using standard fine tip metal tweezers. The System is supplied with a Vacuum Tweezers Kit which consists of a Vacuum Pump (1) and tweezers (2).

  • Page 10: Connecting The Pirani Gauge

    Connecting the Pirani Gauge The surfaces where the O-ring (1) sits should be completely free of dirt. The O-rings should be smeared with a small amount of vacuum grease before loading in between the Pirani Gauge (2) and the Stage Vacuum Connector (3). Ensure that the O-ring is correctly seated in the gauge and vacuum connector before tightening the Clamping Bracket (4) screw (5).

    Clamping Bracket (4) screw (5). Connect the other end of the Flexible Stainless Steel Vacuum Tube to a Vacuum Pump. Vacuum Pump Note: the FDCS196 is tested with a vacuum of mBar. Do not use a vacuum lower than this.

  • Page 12: Fdcs196 Pro System Setup

    Mounting the MV196 The MV196 has an vacuum flange just like the vacuum ports on the sides of the FDCS196 Stage. Use a small amount of vacuum grease to coat a thin layer on the surface where the O-ring will sit.

  • Page 13: Sample Preparation And Loading

    Sample Preparation and Loading The stage chamber must first be prepared for vacuum. Ensure that the chamber is completely clean and dry inside. Finger grease and dirt must be cleaned off with IPA (isopropanol). Sample Loading Using G16.3 Sample Holder A Freeze Drying Sample is prepared using a G16.3 Sample Holder (1).
  • Page 14 At standard atmospheric pressure the contact between the sample and the silver block is enough to establish good thermal contact as the air molecules in any minute scratches will conduct the heat, but when pulling a vacuum these are drawn out of the stage. Objective immersion oil (supplied) has the same refractive index as quartz and ensures an almost perfect thermal seal between block and crucible.
  • Page 15 Pipette 2μl of sample on the Quartz Sample Win- dow inside the Shim Spacer. Use the supplied Vacuum Tweezers or a pair of tweezers place a clean W13G, (13 x 0.17mm) Glass Sample Window on top of the sample, ensuring it touches the Shim Spacer. Use the XY manipulators to move the Sample Holder so the edge of the sample sits across the aperture hole of the silver block.

  • Page 16: Sample Loading Using Fdcs196/Cc Crucible Carrier And Quartz Crucible

    Sample Loading Using FDCS/CC Crucible Carrier and Quartz Crucible This method is used if you are preparing the sample away from the FDCS196 stage. The crucible carrier has two spring clips to hold the crucible flat against the silver block. This is to ensure good thermal contact.
  • Page 17 Pipette 2μl of sample inside the Shim Spacer. Use the supplied Vacuum Tweezers or a pair of tweezers to place a clean W13G, (13 x 0.17mm) Glass Sample Window on top of the sample, ensure it touches the Shim Spacer. Before loading the Crucible Carrier the silver block must be prepared with silicon oil to provide a good thermal contact between the crucible and...
  • Page 18 Load the Crucible Holder with the prepared sample into the FDCS196 stage. Unscrew the Y manipulator (the one screwed into the stage door) so that when you close the door, the FDCS/CC doesn’t push the crucible right off the edge of the block and the silicon oil with it.

  • Page 19: Cooling Connections

    Cooling Connections These connections need only be made if the experiments are to be carried out below room temperature. The Dewar Siphon (1) is the thick white foam tubing and is attached to the liquid nitrogen Dew- ar. The thin black capillary tube inside the white foam tube must be inserted into the liquid nitro- gen cooling connectors on the stage.

    “click” when the two parts are connected properly. To remove the Gas Insert, just push back the outer sleeve of the Gas connector toward the base of the FDCS196 Stage and the Gas Insert should drop out.

  • Page 21: Window Assembly

    Window Assembly Lid Window Assembly To replace the windows in the Stage Lid (1) use the Window Tool (2) and align the two wide spacing pins to the Tube Clip Holder holes and unscrew the Lid Insert (3). The Stage Lid and Lid Insert should be turned upside down as shown in the diagram opposite and reassembled in the order indicated.

  • Page 22: Troubleshooting

    Troubleshooting Cooling fault diagnosis Ensure that all connections to the stage and Dewar are as described in the specific manual and that the stage lid and top windows are properly sealed. 1. The cooling rate is less than programmed. There can be several causes of this problem, the most likely being that one of the connectors has become blocked or damaged.
