Agilent Seal Piercer Microplate Sealing Film Perforator

Overview

The Agilent Seal Piercer is a precision-engineered microplate sealing film perforator designed for high-integrity, repeatable puncturing of heat-sealed films across 96-well and 384-well microplates. Operating on a deterministic mechanical piercing principle—rather than thermal or ultrasonic methods—the device delivers controlled, non-destructive penetration of polyolefin, aluminum-laminate, and foil-based seals without compromising well integrity or generating particulate debris. With a fixed cycle time of ≤4 seconds per plate, the Seal Piercer is optimized for integration into regulated laboratory workflows where throughput, reproducibility, and operator safety are critical. It functions either as a standalone benchtop unit or as a modular component within Agilent’s PlateLoc thermal sealing ecosystem—enabling seamless transition from sealing to perforation in automated liquid handling or assay preparation lines.

Key Features

• Dual-Format Interchangeable Piercing Heads: Field-replaceable 96-pin and 384-pin piercing modules feature hardened stainless-steel needles with precisely calibrated tip geometry and depth control (max. 3 mm penetration), ensuring consistent film breach across variable seal thicknesses and plate well depths—including deep-well formats (e.g., 2 mL storage plates).
• Hardware-Interlocked Front Access Door: Electromechanical interlock system halts all actuation upon door opening, meeting IEC 61000-6-2 and ISO 13857 safety requirements for laboratory equipment. Status LEDs provide real-time visual feedback on door state, sensor readiness, and cycle completion.
• Flexible Integration Architecture: Equipped with RS-232 and TTL-compatible I/O ports for bidirectional communication with host controllers (e.g., LIMS, robotic orchestration software). Supports both manual operation via tactile keypad and fully automated plate handling via articulated robotic arms—no compatibility with BenchCel platforms, as confirmed by Agilent’s system interoperability documentation.
• Minimal Maintenance Design: Needle alignment is factory-calibrated and sealed; no user recalibration required. All wetted surfaces comply with USP Class VI biocompatibility standards, and the housing meets IP20 ingress protection rating for standard laboratory environments.

Sample Compatibility & Compliance

The Seal Piercer accommodates ANSI/SBS-standard microplates (including low-profile, skirted, and full-skirt formats) sealed with thermoplastic films (e.g., polyester-backed polypropylene), aluminum laminates, and foil composites. It does not support adhesive-based or pressure-sensitive seals. Device firmware and mechanical design conform to ISO/IEC 17025 calibration traceability frameworks, and operational logs—including cycle count, timestamp, and door-open events—are retained internally for GLP/GMP audit readiness. While not FDA 21 CFR Part 11–certified out-of-the-box, the instrument supports electronic record export (CSV) compatible with validated data management systems under controlled validation protocols.

Software & Data Management

No embedded operating system or proprietary GUI is included; control logic resides in firmware-level microcontroller code. All operational parameters (e.g., pierce dwell time, head selection, error recovery mode) are configured via ASCII command protocol over serial interface. Audit-trail-capable systems may capture command logs and status responses for compliance reporting. Agilent provides technical documentation—including electrical schematics, mechanical drawings, and firmware revision history—under NDA for qualified integrators performing IQ/OQ/PQ validation.

Applications

• Pre-injection sample access for LC-MS, GC-MS, and HPLC autosamplers using sealed microplates
• Enabling post-seal reagent addition or dilution in HTS assay development workflows
• Facilitating gas-phase equilibration (e.g., headspace analysis) through controlled venting of sealed plates
• Supporting stability-indicating studies requiring long-term storage under inert atmosphere followed by periodic sampling
• Integration into Agilent BioTek Cytation or Synergy multimode reader workflows where sealed plate integrity must be preserved until measurement initiation

FAQ

Is the Seal Piercer compatible with non-Agilent microplate sealers?
Yes—provided the seal film type and thickness fall within the specified range (25–125 µm); however, optimal performance and warranty coverage require use with Agilent PlateLoc thermal sealers due to synchronized thermal profile and dimensional tolerancing.
Can the piercing depth be adjusted by the user?
No—penetration depth is mechanically fixed at 3.0 ± 0.1 mm per needle to ensure repeatability and prevent well wall contact; adjustment requires factory recalibration.
Does the device generate aerosols or particulates during piercing?
Independent SEM-EDS analysis confirms negligible particulate generation (<0.1 µg per 96-well cycle); no filtration or exhaust coupling is required under standard ISO Class 5–7 lab conditions.
What maintenance intervals are recommended?
Visual inspection every 1,000 cycles; needle head replacement every 10,000 cycles or when visual wear exceeds 5 µm tip erosion (measured via optical profilometry).
Is remote diagnostics supported?
Diagnostic mode is accessible via serial command ‘DIAG?’, returning real-time sensor states, motor current draw, and EEPROM checksums—intended for Agilent Field Service Engineers only.
