Nanovoltmeter

Measure low noise voltage and characterize low resistance materials and devices. Higher measurement speed and great noise performance. It offers a simplified delta mode for making resistance measurements in combination with a reversing current source. Usually used in research to determine the transition temperature of superconductive materials or the ability of a material to absorb heat.

DC and AC Current Source

Measures and outputs both DC and AC. Source and sync programmable load 100fA to 100mA. 1014 output impedance ensures stable current sourcing into variable loads. Applications include replacement for lock-in amplifiers, optoelectronics, nanotechnology, differential conductance, pulsed sourcing, and measuring resistance with low noise.

Switch Control System

Measure temperatures with a thermocouple, control via internet, timestamp to see how temperature changes over time, measure 2 channels at once. Provides a convenient mechanical and programming environment for a variety of plug-in modules. With the appropriate plug-in modules, the Switch/Control System provides high density/high speed switching and digital I/O capability.

Hotplate / Stirrer

This device is used to make a stir bar, immerse in a liquid, quickly spin, or stirring or mixing a solution. At the same time, the plate can be heated up to 500°C. Applications involve chemical reactions and heating up samples.
