Linkam - Heating and Cooling Stages

THMS600 Heating and Freezing Stage
The THMS600 is one of the most popular heating and freezing stages on the market. Over 800 stages have been sold around the world to date, it is used in many applications where high heating/freezing rates and 0.1°C accuracy and stability are needed.

Liquid samples can be introduced into the stage with a quartz crucible through the side door without having to remove the lid.

Electrical connections within the sample chamber can be added enabling various electrical measurement to be made on the sample during precise heating or cooling rates.

LTS350 Heating and Freezing Stage

The LTS350 is an easy to use versatile heating/freezing stage, with simple microscope slide mounted sample loading. The stage is optimised for isothermal sample analysis applications where high speed heating and cooling are compromised by larger sample area with excellent thermal stability of less than 0.1C.

The stage consists of a large area temperature controlled element with a platinum resistor sensor embedded close to the surface for accurate temperature measurements.

Electrical connections within the sample chamber can be added enabling various electrical measurement to be made on the sample during precise heating or cooling rates.

LTS120 Analysa Peltier system

This peltier controlled system provides a turnkey solution for unrivalled temperature stability and control within a smaller temperature range than the LTS350 based Analysa systems. Although the LTS120 stage has a narrower range in temperature, the system does not require liquid nitrogen to cool and can reach temperatures as low as -40°C using just circulated cooling water to achieve significant delta T values.

Electrical connections within the sample chamber can be added enabling various electrical measurement to be made on the sample during precise heating or cooling rates.

BCS196 Cryobiology Microscope Cooling Stage

Liquid nitrogen is injected directly into the block by the LNP94/2 cooling pump automatically controlled by the temperature programmer. Temperature feedback is provided by a pt100 platinum resistor to give <0.01s response time.

By precisely controlling the rates of cooling and heating of the microscope stage, ice crystal morphology can be intimately controlled and investigated. Recycled nitrogen gas is used to purge the microscope stage of moisture and prevent condensation hence enable the capture of clear highly resolved images.For ice crystal seeding, a cold spot has been provided on one of the cooling pipes allowing nucleated freezing to be initiated.

Cryobiology Pro System

This system has been has been developed for the specialized field of cryobiology where extremely accurate temperature and position of the sample aswell as cooling rates of up to 5000°C/min are required.

The MDBCS196 is the ultimate in cryomicroscopy. High speed quench cooling is acheived by moving the sample from a copper 'warm post' onto a pre-cooled block, at high speeds. Because the speed can be varied from 5 to 5000µm/s it is possible to observe the effect of crystallisation at extremly high cooling rates.

Inverted Microscope Peltier Systems

These heating and cooling stages are designed to fit into the table or replace the table of your inverted microscope. The stage is then flush with the surface of the table enabling the use of standard sample manipulators to be used.

The planar design of the stage allow complete access to the sample and facilitates the use of petri dishes, well plates and microscope slides The table below shows the compatibility of the Linkam inverted peltier stages with specific microscopes.

PE120 Peltier Heating and Freezing Stage

The PE120 stage is a simple to use thermoelectrically cooled stage that accurately controls the temperature of microscope slides to +/-0.1C from -25 to 120°C. As a low cost turn key temperature controlled system this stage is ideally suited to basic temperature application work.

Sample area is 35x32 mm, with a 5 mm aperture. Minimum objective working distance is 0.1mm. Minimum condenser working distance is 5mm. Stage size is 115 x 76 mm.

Optical Rheology Heating and Cooling System

The Linkam Optical Shearing System (CSS450) allows structural dynamics of complex fluids to be directly observed via standard optical microscope while they are under precisely controlled temperature and various shear modes.

Using the optical shearing cell, it is possible to study the microstructure evolution of complex fluids in great details for many physical processes, e.g. coarsening of binary fluids during their phase separations, flow-induced mixing and demixing of polymer blends, defects dynamics of liquid crystals, aggregation of red blood cells and their deformation in flows etc

FTIR600 Heating and Freezing Stage (Infrared)

The FTIR600 stage has been adapted from our market leading high precision geology stage to allow infra red analysis of samples from -196 up to 600°C covering all applications from pharmaceutical to polymers.

The FTIR600 stage can be mounted horizontally as in IR microscopy setups and vertically for cabinet type IR spectroscopy. The silver block has a tapered hole to allow maximum transmittance of IR without interference. The angle admittance from the condenser is 85° and that of the objective is 116° .

GS120 Temperature Gradient System

With this peltier based temperature gradient stage it is possible to program extremely accurate gradients across the sample. Two heating elements are perfectly aligned to ensure uniform thermal contact between the temperature controlled surface and the sample media.

The heating elements are separated by a 2.5mm gap and can be controlled to 0.1°C from -25 to 120°C allowing significant temperature gradients to be set up. Linksys software enables the precision stepper motor to control the position and the speed of sample movement between the two elements and can be used to determine speed of crystal growth and allow the crystallisation front to remain in the field of view.

Freeze Drying Microscope System

Using the FDCS and light microscopy techniques such as phase contrast and polarized light, it is now possible to accurately determine collapse and eutectic temperature and intricately investigate freeze dried structure of complex samples. Both stage pressure and temperature can be accurately controlled and programmed to simulate industrial procedures and determine ideal drying parameters.

Temperature is measured to 0.01°C by a Pt100 resistor mounted close to the sample and controlled to 0.1°C even down to pressures as low as 10-3 mbar.

High Temperature System

This high temperature system is a turnkey solution complete with hotstage, programmer and water circulator.

The TS1500 stage is ideally suited to the study of ceramics, metallurgy, materials, geology and high temperature polymers at both high and low heating and cooling rates.

The body, lid and window are water cooled ensuring both the user and the lens are protected from the extreme temperatures inside stage.
