Using CryoLab to measure Seebeck coefficients: Video from DEMCON kryoz explains

The Seebeck effect is the direct conversion of temperature differences to electric voltage and vice versa. A thermoelectric device creates voltage when there is a different temperature on each side. Conversely, when a voltage is applied to it, it creates a temperature difference.

By using the CryoLab from DEMCON kryoz, it is possible to measure the Seebeck coefficient of a material sample, wire or thin film from 373 Kelvin down to cryogenic temperatures. In this informative video, DEMCON kryoz demonstrate how such measurements are made using their equipment. For more information, please contact us.




The Model 155 MeasureReady™ power source offers unprecedented simplicity and intuitive operation as video shows

Lake Shore’s new Model 155 MeasureReady™ precision I/V source is ideal for demanding scientific applications requiring a precise low-noise supply of current or voltage, for example electronic material characterisation. Supplying 1 W maximum from DC to 100 kHz over a broad output range, these power supplies deliver a solid foundation for I/V curve, Hall effect, and other fundamental measurements.

The clutter-free touch display with a unique TiltView™ screen presents a natural and engaging user interface. No confusing buttons or long learning curves make the Model 155 as easy to use as a smartphone. With similar connectivity – Bluetooth, Wi-Fi, USB, plus LAN – it offers convenient remote operation via LabVIEW™, a custom PC interface, or mobile app.


  • Bipolar, 4-quadrant I/V source
  • DC and AC modes supported up to 100 kHz
  • Full scale ranges from 10 mV to 100 V (1 µA to 100 mA)
  • 0.001% programming resolution
  • Low peak to peak noise: from 1 µV at 10 mV full scale
  • Manual and autorange function
  • Smartphone-based touchscreen user interface

R&D Magazine declares the 8600 VSM from Lake Shore Cryotronics a winner

The 8600 Series VSMs from Lake Shore Cryotronics [ @LakeShoreCryo ] has been recognised as one of “100 most technologically significant new products in 2017” at an awards ceremony organised by R&D Magazine.

The VSM was re-imagined, focusing on a clean ergonomic design that would simplify a researcher’s interaction with the system. For example, a motorised head brings the sample to a comfortable height for easy, one-handed exchange of the sample rods.

This superior magnetometer, through both performance and convenience, offers very high sensitivity and a super-fast magnetic field ramp rate. Temperature options include a cryostat, high-temperature oven, and single stage variable temperature insert. The combined temperature range of the options is 4.2 to 1273 K, and all three options quickly slide into place and are auto-detected by the system’s software – video demonstration.

8600 Series Features

  • 0.25 × 10-7 emu noise floor at 10 s/pt
  • 10 ms/pt data acquisition rate
  • 10,000 Oe/s field ramp rate
  • Rapid, repeatable temperature option exchange
  • High stability—±0.05% per day
  • Fields to 3.26 T
  • Widest available temperature range—4.2 K to 1273 K

The magnet poles are also easily adjusted with a specially designed indexed positioning system that allows the pole gap to be set at one of six repeatable positions, eliminating the need to recalibrate after each change.

5 electronic measurement pitfalls you’ve probably forgotten about…

Kevin Carmichael, of Lake Shore Cryotronics, has authored a paper outlining common errors that can be made during precision electronic measurements. Whether you are new to electronic device measurements or a pro, you’ll want to avoid these pitfalls to prevent:

  • Voltage errors
  • Current leakage
  • Ground loops
  • Field-induced interference
  • Source-related noise

Lake Shore’s temperature sensor data is now online

Lake Shore is now offering all their temperature sensor information in one convenient online page. The new Sensors’ page contains links to:

  • Datasheets
  • Installation instructions
  • Application notes
  • Catalogue pages

Lake Shore logoOver the coming months, Lake Shore will migrate away from shipping calibration data CDs with calibrated sensors and will instead only offer this data via a portal accessible from the new page.

Data is currently available online for sensors shipped since the beginning of 2016, so if an existing CD is lost or damaged, the calibration data can be quickly downloaded providing you have the serial number of the relevant sensor on hand. Alternatively, contact Lake Shore Service for archived curves.

Lake Shore space-qualified sensors were on the hugely successful Cassini Huygens mission to Saturn that ended earlier this month.

Nearly twenty years of gathering temperature information in an extreme environment is a good advert for their sensors, and Elliot Scientific often supplies them to the aerospace industry and space scientists in the UK and Ireland.
