Rainin Pipet-X™ Electric Pipette

Overview

The Rainin Pipet-X™ Electric Pipette is an ergonomically engineered liquid handling instrument designed for high-precision, high-volume manual pipetting in regulated and demanding laboratory environments. Unlike traditional air-displacement pipettes, the Pipet-X™ employs a brushless DC motor-driven piston mechanism coupled with intelligent pressure-sensing feedback to deliver consistent aspiration and dispensing across its full 0.1–100 mL range. Its core architecture integrates modular components—including a sterilizable adapter interface, hydrophobic filtration, and vapor-exhaust ventilation—to mitigate cross-contamination risks and ensure long-term mechanical integrity during extended use. Engineered for reproducibility under variable thermal conditions (10–35°C operating range), it supports routine QC workflows, cell culture preparation, reagent bulk transfer, and sample dilution protocols where volumetric accuracy, operator fatigue reduction, and biosafety compliance are critical.

Key Features

• Ergonomic lightweight design: Total mass of only 190 g minimizes wrist strain and repetitive motion injury risk during prolonged operation—validated per ISO 11228-3 ergonomic assessment guidelines.
• Autoclavable adapter interface: Fully compliant with DIN EN 285 for steam sterilization at 121°C and 2 bar pressure, enabling seamless integration into aseptic workflows without disassembly.
• Hydrophobic 0.2 µm filter: Pre-sterilized, integrated filter prevents aerosol ingress and protects internal drive mechanisms from liquid intrusion and corrosive vapors.
• Vapor exhaust system: Actively vents aspirated aerosols outward through a dedicated channel, reducing internal condensation and preserving electronic component longevity.
• Extended battery runtime: Rechargeable 2.4 V / 700 mAh NiMH battery supports up to 8 hours of continuous operation when paired with standard 10 mL serological pipettes—ideal for high-throughput labs with limited charging infrastructure.
• Thermal resilience: Stable performance across 10–35°C ambient conditions; storage-rated up to 50°C, ensuring reliability in non-climate-controlled environments such as cold rooms or warm incubator suites.

Sample Compatibility & Compliance

The Pipet-X™ accommodates all standard conical-tip serological pipettes (0.1–100 mL), including those made from polystyrene, polypropylene, and low-binding treated plastics. Its sealed motor housing and filtered airflow path meet IEC 61000-6-2 electromagnetic immunity requirements and are compatible with biosafety level 2 (BSL-2) containment practices. The autoclavable PX-SA adapter and PX-020 filter comply with ISO 8573-1:2010 Class 4 purity standards for compressed-air–free aspiration systems. Device documentation supports audit readiness for GLP and GMP environments, with traceable calibration records aligned to ISO/IEC 17025 principles. While not inherently 21 CFR Part 11–compliant (as it lacks embedded electronic signature capability), its operational logs—when captured via optional Rainin LiteTouch™ software—can be archived within validated LIMS platforms meeting FDA regulatory expectations.

Software & Data Management

The Pipet-X™ operates as a standalone instrument but interfaces seamlessly with Rainin’s LiteTouch™ PC software suite (sold separately) for protocol configuration, usage logging, and preventive maintenance scheduling. LiteTouch™ generates timestamped activity reports—including total aspirated volume, cycle count, and battery health metrics—which may be exported in CSV or PDF formats for internal quality review. All firmware updates are delivered via USB-C connection and include cryptographic checksum verification to ensure integrity. Software-generated logs support retrospective analysis for root cause investigations in deviation events, aligning with ALCOA+ data integrity principles (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available).

Applications

• Preparation of media and buffers in cell culture and microbiology laboratories
• Serial dilution of clinical specimens in diagnostic testing workflows
• Transfer of viscous or volatile solvents in analytical chemistry sample prep
• High-volume reagent dispensing for ELISA, PCR setup, and NGS library construction
• Environmental water sampling and wastewater analysis requiring field-deployable sterility assurance
• Teaching laboratories emphasizing ergonomic best practices and contamination control fundamentals

FAQ

Can the Pipet-X™ be used with positive displacement pipettes?
No—the Pipet-X™ is specifically designed for air-displacement serological pipettes. Positive displacement tips require direct piston contact and are incompatible with its adapter geometry.
Is the PX-NIMH battery replaceable by the end user?
Yes—the PX-NIMH battery module is field-replaceable using standard Torx T5 tools; no soldering or factory recalibration is required post-installation.
Does the device require routine calibration per ISO 8655?
While the Pipet-X™ itself is not classified as a “volumetric instrument” under ISO 8655 (which applies to fixed-volume pipettes), its performance must be verified periodically using gravimetric methods per ISO 8655-6 when used in regulated applications.
What is the expected service life of the PX-020 filter under normal lab use?
Under typical BSL-2 conditions with aqueous solutions, the PX-020 0.2 µm filter maintains integrity for approximately 200–300 aspiration cycles before replacement is recommended.
Can the PX-SA adapter be sterilized repeatedly without degradation?
Yes—DIN EN 285 validation confirms ≥50 autoclave cycles at 121°C, 2 bar without measurable loss of dimensional stability or sealing performance.
