Heating and Cooling stages

HCP621G Hot/Cold Plate

The HCP621G gas tight plate is designed for applications where both thermal and atmospheric control is critical. Using a silver heating and cooling block, this plate provides a wide temperature range with exceptional thermal uniformity. The gas tight chamber creates a closed environment to eliminate oxidation, aid in humidity studies, or conserve expensive reacting gases. Additionally, up to 8 optional feedthrough leads are available for sample connection and probing.

According to heating and cooling stages temperature-based studies on samples with microscopes, spectrometers, there is need for a reliable, stable stage that can work under thermal and atmospheric conditions such as low temperature, high temperature and sub-zero temperatures. The stage should be thermally stable, leak tight to allow vacuum or gases and should be simple to use. The thermal block needs to be a good conductor typically a silver or similar metal body. The seal should be good enough to allow vacuum and / or gas to be held for a long period without leakage. The temperature controller with Liquid Nitrogen should be able to set temperatures quickly without any overshoot. The size of the stage needs to be small to suit the sample space in microscopes and spectrometers. Optical window material decides the wavelength that can pass thru for irradiation of sample. Typical window materials include Fused Quartz, Glass and Sapphire. Other materials can be quoted on request.

KEY FEATURES

Compact Design

Suited for use on upright microscopes, optical benches, and other instruments with limited space.

Wide Temperature Range

-190°C to 600°C (with optional LN2 cooling accessory)

Rapid Heating Rates

+150°C per minute max rate

Gas Tight Chamber

Allows for gas purging for defrosting and prevents condensation and oxidation. Also allows for a controlled atmosphere around sample. Features quick connect and release gas ports

Accuracy and Stability

A pt100 platinum RTD sensor is embedded into the sample heating and cooling block to guarantee high temperature accuracy and stability. The RTD sensor is calibrated to measure the temperature of the surface of the sample heating block – giving the closest and most accurate reading of sample possible. Additional sensor option and alternative sensor, such as a thermistor, option is also available.

Additional Features

• Includes standalone mK2000 temperature controller
• Includes ‘InstecApp’ Windows compatible software for optional operation via PC
• Comes standard with optical glass windows that can be easily replaced with IR or UV transparent glass.

OPTIONS

Controlled Cooling

Extend lower temperature limit to -190°C with LN2-P cooling accessory; includes tubing and dewar (2L, 10L, or 30L). Enables active cooling with rates of up to -50°C per minute (at 100°C).

Frame Cooling

Safety always comes first – keep the frame of the HCP621G cool and safe to touch with an optional water circulator. (see C100W chiller) Frame cooling option allows thermal control of frame independent of sample thermal block and aids in preventing frost buildup when cooling sample is being cooled below freezing temperatures.

Spacer Set

Increase chamber height with fitted spacer kit to allow fitment of taller samples, while maintaining the gas tight capability with the top cover.

XY Sample Positioning

Position sample while maintaining a sealed chamber with the optional XY positioner (see HCP621GXY). With greater flexibility, sample area accessibility, and precision control, this option is optimal for use with a rotational stage on a polarizing microscope due to the directional nature of polarization

Inner Cover

The chamber height is the distance between the top surface of the thermal block and the bottom surface of the outer cover. With an optional inner cover, the distance is minimized in design to allow for just enough eight for intended samples (slides, slipcovers, wafer pieces, etc.) and to decrease the minimum objective working distance. By closing the distance, the vertical temperature gradients are also significantly reduced.

Electrical Feedthroughs

Add up to 8 electrical feedthroughs for applying electric field to sample.

Vacuum Tight Chamber

Can be both gas purged and evacuated to low pressures to protect sensitive samples from moisture and oxygen as well as to study vacuum processes such as freeze drying. (see HCP621V for vacuum compatible model)

Microscope

Entry-level polarizing microscope offering superior performance for a variety of research applications with specifications to satisfy a wide range of demanding observational requirements. (see TPM310-TR)

Camera

Integrate digital image acquisition with sample temperature overlay. Includes software (WinDV thru InstecApp) USB 2.0 connection, 1.92-megapixel resolution, C-mount microscope connection standard. (see MITO2)

Mounting Adapter

Various mounting adapters are available for most microscope models and/or instruments. Custom mounting adapter may also be made to fit each and every application.

Windows

Additionally available windows are Sapphire, BaF2, CaF2, ZnSe (see HCS601GXY-IRM for IR applications).
