Drummond Portable Pipet-Aid XP Electric Single-Channel Pipette

Overview

The Drummond Portable Pipet-Aid XP is an engineered solution for precise, fatigue-free manual liquid handling in dynamic laboratory environments. Unlike traditional bulb or pump-assisted pipetting systems, this motorized single-channel pipette operates on the principle of controlled positive-pressure air displacement—delivering consistent aspiration and dispensing across its full 1–100 mL volume range. Designed specifically for compatibility with standard serological pipettes (including 1, 2, 5, 10, 25, 50, and 100 mL formats), it eliminates hand strain associated with repetitive thumb actuation while maintaining full tactile control over flow rate and endpoint precision. Its ultra-portable architecture—measuring just 14 cm in length and weighing only 230 g—enables seamless integration into biosafety cabinets, laminar flow hoods, field-deployable labs, and teaching laboratories where bench space and mobility are constrained.

Key Features

• Lightweight ergonomic design (230 g) optimized for extended use without operator fatigue
• Rechargeable 9 V nickel-metal hydride (Ni-MH) battery with tool-free replacement capability and >8 hours of continuous operation per charge
• Integrated locking chuck mechanism that secures pipettes firmly across the entire 1–100 mL range; prevents slippage during vertical or angled handling
• Nine independently selectable speed settings—calibrated for both rapid bulk transfer and slow, dropwise dispensing under laminar airflow or low-volatility conditions
• Modular wall-mountable stand with sleeve-style bracket for hands-free storage and immediate access; compatible with standard lab wall rail systems
• Hydrophobic filter protection included (4 units supplied) to prevent aerosol contamination of internal drive components
• CE-marked construction meeting essential requirements of the EU Electromagnetic Compatibility (EMC) Directive 2014/30/EU and Low Voltage Directive 2014/35/EU

Sample Compatibility & Compliance

The Pipet-Aid XP interfaces exclusively with Class A and Class B glass or polypropylene serological pipettes conforming to ISO 648 and ASTM E537 specifications. It does not support volumetric or graduated cylinders, nor does it accommodate non-standard tip geometries. The device’s mechanical interface has been validated for repeated engagement with pipettes featuring conical, tapered, or straight-shaft designs up to 100 mL capacity. For regulated environments—including GLP-compliant analytical labs and clinical QA/QC workflows—the unit supports audit-ready documentation when paired with Drummond’s optional Gravity Drain accessory (model 4-000-202), which enables passive liquid recovery in accordance with USP guidelines for pipette performance verification.

Software & Data Management

As a standalone electromechanical instrument, the Pipet-Aid XP operates without embedded firmware or digital connectivity. All operational parameters—including speed selection and pipette clamping force—are adjusted manually via tactile rotary dial and mechanical latch. This analog control architecture ensures zero risk of electromagnetic interference in sensitive instrumentation zones (e.g., near NMR spectrometers or electrophysiology rigs) and eliminates dependency on software updates, driver installations, or network authentication. Calibration verification is performed using gravimetric methods per ISO 8655-2, and routine maintenance logs may be maintained in accordance with FDA 21 CFR Part 11–aligned laboratory notebooks where electronic signatures are not required.

Applications

• Cell culture passaging and media preparation in biosafety level 2 (BSL-2) containment
• Pre-analytical sample dilution and aliquoting in clinical chemistry and microbiology labs
• Reagent dispensing for ELISA, PCR setup, and immunoassay workflows
• Field-based environmental sampling where AC power is unavailable
• Undergraduate and graduate teaching labs requiring intuitive, low-maintenance liquid handling tools
• QC testing of raw materials in pharmaceutical manufacturing facilities operating under cGMP Annex 1 guidelines

FAQ

Is the Pipet-Aid XP compatible with plastic disposable pipettes?
Yes—it accepts all standard 1–100 mL serological pipettes made from borosilicate glass or autoclavable polypropylene, including major OEM brands compliant with ISO 648.
What is the expected battery life under typical usage?
With moderate use (approx. 300 pipetting cycles per day), the Ni-MH battery delivers ≥8 hours of active operation before requiring recharge via the included 220 V adapter.
Can the device be sterilized or cleaned with ethanol or isopropanol?
The external housing is chemical-resistant to 70% ethanol and isopropanol; however, submersion or ultrasonic cleaning is prohibited. Wipe-down with lint-free cloth is recommended.
Does Drummond provide calibration certification with purchase?
No factory calibration certificate is included by default; users must perform initial gravimetric verification per ISO 8655-2 and document results internally for compliance purposes.
Is the Gravity Drain accessory required for regulatory compliance?
Not universally—but it is strongly recommended for labs conducting USP -aligned pipette performance qualification (PPQ) studies where passive drainage validation is mandated.
