New VSM series from Lake Shore: Introducing the 8600

The new 8600 Series VSM from Lake Shore Cryotronics raises the bar for magnetometer performance and convenience by combining high sensitivity, rapid measurement speeds, and ease of operation for faster and more accurate measurements.

The entire 8600 Series system has been re-imagined with a focus on a clean, ergonomic design that simplifies the 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.

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

  • 0.33 × 10-7 emu noise floor at 10 s/pt
  • 10 ms/pt data acquisition rate
  • 5000 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.


The new 8600 Series VSMs will be available from April 2017 onwards. Please contact us with regard to pre-orders.


Lake Shore’s 7400 Vibrating Sample Magnetometer is the most sensitive available today

VSM_SQLake Shore’s Vibrating Sample Magnetometer systems (VSM) can measure all types of magnetic materials in bulk, powder, thin film, single crystal, and liquid form, and the latest 7400 series Vibrating Sample Magnetometer is the most sensitive VSM available today.

This VSM features a noise floor of 1 x 10-7 emu at 10 seconds/point sampling, 4 x 10-7 emu at 1 second per point and 7.5 x 10-7 emu at 0.1 seconds per point. In addition to providing the lowest noise floor, the 7400’s patented technology leads to a stability of 0.05% per day which surpasses the stability of any other commercial VSM.

Under full software automation it can measure and record hysteresis M(H) loops, torque curves, isothermal and DC demagnetisation remanence curves, and temperature dependent magnetic properties.

Models based on variable gap 4″, 7″ and 10″ electromagnets are available, providing field strengths to above 3 T. While variable gap magnets allow for easy reconfiguration of the magnet gap to accommodate large samples of up to 1″.
