Lakeshore Cryotronics 7407-S Material Test

Vibrating Sample Magnetometer.
Lake Shore’s fully integrated vibrating sample magnetometers
(VSMs) are used to characterize the DC magnetic properties of
materials as a function of magnetic field, temperature, and
time. Sensitive, low-noise floor electromagnet-based VSMs that
feature a broad temperature range capability—4.2 K to
1,273 K (-269 °C to 1000 °C).
These systems measure a wide range of sample types,
making them ideal tools for the most demanding
materials research applications as well as quality control of
magnetic materials.
Combines high sensitivity, precision electronics,
flexible software, and variable magnetic field and
temperature into the most advanced electromagnet-
based VSM.
Includes Lake Shore 74034 High Temperature oven enables
the Model 7400 series VSM system to be used to investigate the
magnetic properties of materials at high temperature.
This option consists of an electrically heated outer tube
assembly with efficient thermal insulation to
permit sample-zone temperature from 100 °C to 1000 °C
(373 K to 1273 K). Temperatures from 30 °C to 1000 °C
(303 K to 1273 K) are also possible, however,
below 100 °C (373 K) measurement time increases.
Also includes the Janis Research 74018A
Variable Temperature Cryostat designed for
rapid sample cooling with either LHe or LN2 as
well as easy sample insertion and interchange.
It allows you to take measurements from 5.5 K to
450 K using LHe and from 85 K to 450 K using LN2.
A single-point measurement can be taken at 4.2 K (LHe) and
at 77.6 K (LN2). The sample is suspended in
a proprietary insulated tube constructed of
nonmagnetic material.
