Polished 1″ Quartz Crystals for Liquid QCM Systems – SRS QCM100/QCM200 Compatible

Description

Designed specifically for liquid-phase QCM applications, these 1″ AT-cut quartz crystals deliver stable, precise frequency response in submerged or electrochemical environments. Polished and flat in profile, each crystal features a wraparound electrode to allow full electrical contact from one side—making them ideal for sensor heads that are immersed in liquids.

Manufactured by Phillip Technologies, these crystals are fully compatible with:

• Stanford Research Systems: QCM100, QCM200, EQCM

• Maxtek: PM 700 series, RQCM

• PLO-10i and other commercial liquid QCM heads

What Makes These Crystals Ideal for Liquid Monitoring?

Compared to vacuum-deposition QCM crystals, these are built specifically for stability and cleanliness in liquid-phase use:

• 1″ diameter: Larger surface area provides greater resonance stability

• Flat geometry: Eliminates curvature for clean oscillation in viscous or aqueous media

• Double-sided polishing: Minimizes drag from water or electrolyte during oscillation

• Wraparound electrode design: Enables single-sided electrical contact—essential for immersion

• Submersion-ready: Designed to work with O-ring seals in liquid QCM holders to prevent electrical shorts

Technical Specifications

• Pack Size: 4 crystals per box

Please select your desired frequency option when ordering.

Packaging

Each pack of four crystals is enclosed in a cleanroom-compatible tray that preserves surface quality and prevents contact with the active sensing area:

• Top Shell: Rigid, pharmaceutical-grade PETG

• Base Tray: Hand-cleaned polystyrene

• No anti-static agents that can leach onto quartz surfaces

• Designed to ensure zero contact within 3 mm of the resonating center

You get precision crystals—delivered clean, dry, and ready for immediate lab use.

Typical Applications

These crystals are trusted worldwide for research in:

• Electrochemistry and redox reactions

• Protein adsorption and biomolecular interactions

• Immunosensors and biosensors

• RNA/DNA hybridization studies

• Biofouling/antifouling evaluations

• Langmuir-Blodgett films, SAMs, MIPs

• Thin-film plating (CIGS, PVD, CVD)

• Corrosion and surface oxidation testing
