Liquid Cell and Sample Plate

Overview 

The Keysight Technologies, Inc. versatile liquid cell is designed to provide easy setup, a clean imaging environment, and open-cell accessibility. Each cell is made of Kel-F®, which makes thorough cleaning easy and helps prevent cross-contamination when the cell is utilized for different experiments. The unique cell design enables scientists to perform a wide variety of STM/AFM experiments in liquids and/or under electrochemical and/or temperature control (Figure 2). The liquid cell can be used with aqueous, non-aqueous, or harsh (acid/base) solutions. A low-through option allows researchers to monitor real-time changes in surface chemistry or biological processes while exchanging solutions. The unique design of Keysight’s sample plates (Figure 3) delivers superior sample stability and ease of use. Magnetic suspension provides easy loading and eliminates mechanical drift. The standalone plate permits simple sample mounting and customization of the sample plate. A modular design allows the plate to be used with an unparalleled number of options, such as open liquid cells, low through cells, salt-bridge cells (for electrochemistry), Petri dishes (live-cell imaging), and glass microscope slides. Temperature control is available with heating up to 250°C and cooling down to -30°C. All options are available with MAC Mode, Keysight’s patented technique for high-resolution AFM imaging in fluid. The integrated electrode connection permits easy hookup for electrical measurements and electrochemistry applications. Additional sample plates may be added for multiple samples and rapid throughput.

Features and Benefits 

• Modular, symmetric plate design accommodates large sample size
• Magnetically suspended plate mounting minimizes mechanical drift
• Preset electrode connector allows quick, simple setup for electrical measurements and electrochemistry applications
• Superior thermal stability facilitates temperature dependent experiments
• Self-contained cell assembly provides easy sample loading and exchange
• Leak-proof cell design prevents damage to samples and instrumentation
• Flow-through cell capability lets researchers monitor real-time changes while exchanging solutions
• Inert, easy-to-clean cell helps prevent cross-contamination 

Temperature Control 

Keysight’s temperature controller uses a patented thermal insulation and compensation design to deliver precise temperature control and excellent stability for high-resolution scanning probe microscopy (SPM). It allows for imaging during temperature changes and is fully compatible with all imaging modes.
