KJ Scientific SMT-100C Manual Vacuum Pick-and-Place Pen

Overview

The KJ Scientific SMT-100C Manual Vacuum Pick-and-Place Pen is a precision-handling tool engineered for non-contact, static-free manipulation of fragile, micron-scale substrates—particularly quartz crystal microbalance (QCM) sensors, thin-film wafers, piezoelectric crystals, and other electrochemical transducer elements used in analytical and thin-film research. Unlike mechanical tweezers or adhesive-based transfer methods, this device employs controlled pneumatic vacuum generation via manual squeeze-actuated diaphragm pump action, eliminating shear stress, surface scratching, and electrostatic discharge risks during placement or repositioning. Its design integrates core principles of low-pressure fluid dynamics and compliant interface mechanics, ensuring repeatable, contamination-minimized handling across cleanroom-compatible workflows in QCM sensor fabrication, electrochemical cell assembly, and surface science sample preparation.

Key Features

• Manual vacuum actuation with ergonomic aluminum body (Ø12 mm × 98 mm), enabling one-handed operation without external power or compressed air sources.
• Six interchangeable vacuum tips (3.2 mm, 6.4 mm, 9.5 mm, 12.5 mm, 16 mm, and 19 mm nominal diameters), each calibrated to deliver predictable holding forces ranging from 3 g to 500 g under standard ambient conditions (23 °C, 50% RH, 101.3 kPa).
• Dual-tip-material system: Class A tips formulated from chemically inert, high-temperature elastomers (resistant to HCl, NaOH, acetone, IPA, and temperatures up to 120 °C); Class B tips fabricated from carbon-black–loaded conductive elastomers suitable for grounding-sensitive QCM electrode handling and high-temperature superconducting substrate alignment.
• Tip geometry options include straight and 45° bent configurations to accommodate confined-stage access and angled deposition geometries common in sputtering, evaporation, and spin-coating setups.
• Modular construction allows rapid tip replacement and cleaning; all components comply with ISO 14644-1 Class 5 cleanroom compatibility when handled using lint-free gloves and isopropanol wipe protocols.

Sample Compatibility & Compliance

The SMT-100C is routinely deployed in laboratories performing ASTM E2527-22 (Standard Practice for Handling Piezoelectric Quartz Crystal Sensors) and ISO/IEC 17025-accredited QCM calibration workflows. It supports safe handling of AT-cut quartz blanks (0.5–5 MHz fundamental frequency), gold- or platinum-coated electrodes (5–200 nm thickness), polymer-coated resonators (e.g., PMMA, PEDOT:PSS), and biofunctionalized surfaces without compromising mass-loading integrity or interfacial adhesion uniformity. Tip selection follows documented risk assessment per GLP Annex 13 guidelines for instrument qualification in regulated electrochemical assay development. No lubricants or volatile residues are introduced during operation, satisfying USP Analytical Instrument Qualification requirements for Category B instruments.

Software & Data Management

As a purely manual, non-electronic handling tool, the SMT-100C does not incorporate embedded firmware, data logging, or software interfaces. Its operational parameters—vacuum onset threshold, hold time stability, and release repeatability—are validated through documented operator qualification (OQ) protocols aligned with FDA 21 CFR Part 11 Annex A expectations for manual instrumentation. Users maintain traceability via logbook entries referencing tip lot numbers, calibration verification dates (per internal SOP-QCM-HANDLING-07), and environmental monitoring records (temperature/humidity logs). Integration with LIMS is achieved through standardized metadata tagging of handling events within sample tracking workflows.

Applications

• Placement and alignment of QCM-D (Quartz Crystal Microbalance with Dissipation) sensor crystals onto temperature-controlled liquid cells.
• Transfer of fragile metal-organic framework (MOF)-coated resonators between glovebox chambers and electrochemical workstations.
• Positioning of sub-2 mm diameter electrochemical reference electrodes during microfluidic chip integration.
• Relocation of sputtered gold electrodes prior to dielectric passivation in humidity-controlled probe stations.
• Handling of lithographically patterned piezoelectric substrates during flip-chip bonding alignment sequences.

FAQ

Is the SMT-100C compatible with ISO Class 4 cleanrooms?

Yes—when used with certified cleanroom gloves and cleaned per SOP-CLEAN-04 (isopropanol sonication + nitrogen purge), it meets particle generation limits for ISO 14644-1 Class 4 environments.

Can Class B tips be sterilized using autoclaving?

No—Class B material is rated for continuous use up to 80 °C; autoclaving (121 °C, 15 psi) degrades conductivity and dimensional stability. Dry-heat sterilization at 70 °C for 2 hours is acceptable.

What vacuum pressure range does the manual pump generate?

The squeeze-actuated diaphragm delivers −40 to −65 kPa (gauge) depending on operator technique and tip seal integrity; no external vacuum source is required.

Are replacement tips supplied with lot-specific test reports?

Yes—each tip batch includes a Certificate of Conformance listing nominal OD tolerance (±0.05 mm), durometer (Shore A 45–55), and chemical resistance validation per ASTM D471.
