Linkam Large Sample Area Cooling and Heating stages (>22mm), -195°C to 420°C

 An Introduction to the Linkam LTS Stages

LTS420E-P

The LTS420 is an easy to use and very versatile heating and freezing stage. The stage consists of a large area temperature controlled element with a sensor embedded close to the surface for accurate temperature measurements in the range of < -195°C to 420°C (when used with LNP96 cooling pump).

The sample is easily mounted on a standard microscope slide in direct contact with the heating element and can be manipulated 15mm in both X and Y directions. The sample chamber is gas tight and has valves to allow atmospheric composition control. A humidity compatible version of the stage is also available as are a version with internal electrical connections and probes.

There is also the LTS120 range, featuring heating and cooling without liquid nitrogen, as well as a version for use with an inverted microscope. Please contact us for further details.

For information on transmitted light applications, please ask for CONDENSER EXTENSION LENS options.

LTS420E-P

The LTS420E-P is based upon the heating and cooling technology used in Linkam’s LTS420 stage. It has similar temperature control and range, and its dynamic heating and cooling performance ensures that most electrical component temperature control applications are covered.

The larger stage body allows up to 8 positional tungsten probes (other types can be used) to be attached to electrical connectors within the sample chamber and enables the user to make electrical measurements on the sample, while at the same time accurately controlling the temperature inside a gas tight environment.

The LTS420E consists of a large (53.5mm x 43mm) temperature controlled element with a platinum sensor embedded close to the surface for accurate temperature measurements. The sample is simply placed on the heating element and the probes moved manually to make contact at the appropriate points. Lemo connectors are supplied as standard, but BNC can be used instead.

LTS420E-P Specifications

• Temperature Range < -195°C to 420°C (add LNP95 cooling pump to cool sample below ambient)
• Sample area of 58x43mm
• Quick-release gas valves for atmospheric control
• Swing out lid for easy sample loading
• Can be used with transmitted or reflected light
• Mounts directly to microscope table or substage
• Stage body size - 169 x 110 x 25.8 mm
• 100 ohm platinum sensor
• Temperature stability & accuracy to 0.1°C
• Highly conductive metal for improved heat transfer
• Maximum heating / cooling rate of 30°C/min
• Response time of <1 second at 5°C/min at 50°C
• Objective lens minimum working distance 8.2mm
• Condenser lens minimum working distance 12.5mm

For automatic cooling the sample below ambient temperature down to -195C you will need the LNP96 - Liquid Nitrogen Cooling Systems.
