    Mounting Stage to Microscope with Dovetail Substage The following description is for mounting the 9542 curved clamps set stage on to microscopes which have a circular dovetail substage assembly (1). 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: Setting Up

    If you have purchased a Water Circulation Pump with your system, read the following to set up the pump with the LTS420 stage. Refer to the Water Circulation Pump User Guide for more details. When heating the stage above 300°C for more...

  • Page 10: Sample Preparation

    Loading a Sample The Microscope Slide Holder is fitted on to the LTS420 and the holder should not touch the silver heating/cooling block, it should hover just above Note: if necessary the Microscope Slide Holder can be bent into shape with a little force to help it to hold the microscope glass slide.

  • Page 11: Using The Heat Shield

    Using the Heat Shield If your temperature controlled experiment requires extra temperature stability, use the supplied Heat Shield to cover the heater. Use the Y-manipulator (1) to move the Microscope Slide Holder to the middle of the heating bock and use the X-manipulator (2) to move the Microscope slide holder to the home position (8mm from the edge).

  • Page 12: Cooling Connections

    Cooling Connections These connections need only be made if the experiments are to be carried out below room temperature using the LNP96 system. The Dewar siphon (1) is the thick white foam tubing and is attached to the liquid nitrogen Dewar.

  • Page 13: Filling The Liquid Nitrogen Dewar

    Filling the Liquid Nitrogen Dewar Please follow your health and safety user guide for directions on how to handle liquid nitrogen and ensure that you have the correct safety equipment including gloves and safety goggles. Fill the Dewar approximately 2/3 full and replace the lid with siphon attached.

  • Page 14: Purging The Stage Method 1

    Purging the Stage Method 1 Method 1 uses recycled nitrogen gas produced by the LNP96 from the Dewar. Make sure the stage lid is in place and the stage door is closed. Switch on the temperature programmer and set the limit to 40°C. Press the START button and wait until the temperature limit is reached.

  • Page 15: Purging The Stage Method 2

    Purging the Stage Method 2 This method uses an inert gas from a gas cylinder to purge the stage at temperatures above ambient when the LNP96 is not required. 1. Make sure the Stage Lid is in place and the Stage Door is closed.

    Appendix 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 17: Replacing The Microscope Slide Holder

    (1). Take out the Microscope Slide holder from the XY Manipulator Assembly (2). Do the reverse to replace the LTS420 with a new Microscope Slide Holder. Make sure the 2 holes on the holder are lined up with the two notches (2) on the XY Manipulator Assembly.

  • Page 18: Ltse420 With Internal Electrical Contacts

    LTSE420 with Internal Electrical Contacts Option Only read the following if the stage is supplied with internal electrical contacts for the LTSE420 or Liquid Crystal Pro Stage. LTSE420 Stage The stage is supplied with two internal electrical contact connectors (1) wired to an external Lemo connector (2).

  • Page 19: Using The Internal Electrical Contacts

    Using the Internal Electrical Contact The internal electrical contact has a self-closing spring loaded pin (1). Using a finger tip push in the pin to open the electrical contact and insert a wire into the contact (2). Release the finger when the wire is in place.

  • Page 20: Lemo Connector

    Lemo Connector Remove the Lemo plug by holding it firmly and pull it gently away from the Stage. Wire up the Lemo to your instrument. To reconnect the Lemo, line up the red dot on the Lemo plug (1) to the red dot on the Lemo socket (2) and push the Lemo firmly into place.

  • Page 21: Liquid Crystal Stage Pro

    Liquid Crystal Stage Pro Only read the following if your stage is a LTSE420 Liquid Crystal Pro Stage. The Liquid Crystal System Pro is supplied with a Liquid Crystal Slide Holder (1) and 5x Liquid Crystal Cells (5um gap, capillary fill, ITO coated and anti parallel aligned).

  • Page 22: Troubleshooting

    Troubleshooting Cooling fault diagnosis Ensure that all connections to the stage and Dewar are as described in the specific user guide 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.
