  • Page 16: Adjusting The Probe

    Adjusting the Probe Probe orientation: The probe has a magnetic base (3) and can be placed in any orientation inside the LTSE420-P stage using the metal base plate. Note: be extra careful when placing the Probe near to the PT100 platinum temperature sensor (4), the PT100 is very fragile and can be easily be damaged.

  • Page 17: Change The Angle Of The Needle

    Adjust the length of the needle: Pull end of the needle to the desired length and use a wire cutter to cut the needle shorter. Bend the tip of the needle: Use a pair of flat pliers to bend the tip of the needle.

  • Page 18: Sample Preparation

    Sample Preparation For accurate results it is most important that the surface of the block is extremely clean, since air gaps between the heating block and the sample will result in temperature errors. Use a soft cloth and IPA (iso-propyl alcohol) to clean.
  • Page 19 Or place a standard microscope glass slide (26 x76mm) on top first and then place your sample on top of the microscope glass slide. Arrange the Probes around your sample as re- quired by your experiment. Note: make sure the yellow wires are not touching the silver block.

  • Page 20: 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 connector on the stage.

  • Page 21: Purging Procedure

    Purging Procedure Before starting a cooling experiment, you will need to purge air from the stage chamber with dry nitrogen. This will remove the water in the air which would otherwise condense and freeze on the sample disrupting your image quality. Before you can start purging, the LNP95 must be set to manual mode.

  • Page 22: Purging The Stage Method 1

    Purging the Stage Method 1 There are two methods for purging the stage. Method 1 uses recycled nitrogen gas produced by the LNP95 from the 2L 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.

  • Page 23: 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 LNP95 is not required. 1. Make sure the Stage Lid is in place and the Stage Door is closed.

  • Page 24: Appendix

    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 25: Use Linkpad To Set The Lnp95 To Manual Mode

    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.
