This
high temperature system is a turnkey solution complete with
stage, programmer and water circulator.
The 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.
The sample can be placed on either the standard 7mm sapphire
window or inside a platinum crucible. Both sample mounting
methods are placed inside the 2.5mm deep ceramic sample cup
so that the sample is heated from underneath as well as from
the sides.
There are two gas valves at the sides of the stage body so
that the environment within the stage can be controlled.
The temperature is accurately controlled by the TMS94/1500
programmer via the S-type platinum/rhodium thermocouple. The
PSU connected to the TMS94 enables the TS1500 to heat up to
1500°C from room temperature at an incredible 130C/min.
The programmer contains a d.c power supply - to eleminate
electromagnetic interference- and solid state heater protection
to prevent accidental damage to the stage. Thermocouple linearisation
(linearized to 0.1°C and displayed to 1°C) and cold
junction compensation are performed inside the TMS94/1500.

TS1500 Options
There
are a few TS1500 modifications that can be made in order to
suit more specific high temperature applications:
TS1500E (electrical connections)
TS155V (vacuum ports)
TS1500EV (both electrical and vacuum)
TS1500-6 (6mm deep sample cup)
The TS1500 stage can be fitted with vacuum ports to create
a vacuum inside the chamber as low as 10-3mbar. The image
seen here shows a single vacuum port with the space for a
second blanked off. This second port can be used to attach
a vacuum gauge.
The
image also shows an electrical connector. Inside the stage
chamber are two electrical spring clips that allow various
electrical sample measurements to be made during a heating
profile.
