Nichipet Air Multi-Channel Pipette

Overview

The Nichipet Air Multi-Channel Pipette is a precision-engineered manual liquid handling instrument developed by Nichiryo Co., Ltd., a Japanese manufacturer with decades of expertise in high-accuracy pipetting systems. Designed for repetitive, parallel dispensing across microtiter plates and multi-well assay formats, the Air series leverages air displacement technology — the industry-standard principle for volumetric accuracy in low-to-mid volume ranges (0.5–300 µL). Its core architecture integrates a low-resistance plunger mechanism, optimized spring dynamics, and thermally stable polymer components to minimize operator-induced variability and ensure consistent aspiration/dispense performance across all eight or twelve channels. Unlike electronic pipettes, the Air series delivers exceptional reproducibility without dependency on battery life or firmware updates — making it ideal for regulated environments where operational simplicity and audit-trail transparency are critical.

Key Features

• Ultra-low actuation force: Engineered plunger system reduces thumb pressure by up to 40% compared to conventional manual multi-channel pipettes, significantly lowering user fatigue during high-throughput plate filling.
• Interchangeable tip cones: Compatible with universal low-retention, filtered, and sterile-certified tips meeting ISO 8655-3 specifications; cone geometry ensures leak-free sealing across multiple tip brands.
• Volume adjustment lock: Dual-stage locking ring prevents accidental volume drift during transport or benchtop use — a critical safeguard for GLP/GMP workflows requiring traceable parameter integrity.
• Calibration-friendly design: Fully serviceable at the user level; includes dedicated calibration port and alignment tool for routine verification per ISO 8655-5:2022 protocols.
• Ergonomic grip and balanced weight distribution: Contoured polypropylene housing with textured surface enhances control during extended operation, particularly when working with viscous or volatile solvents.

Sample Compatibility & Compliance

The Nichipet Air series supports aqueous buffers, cell culture media, serum-containing solutions, and moderately viscous reagents (e.g., glycerol ≤20% v/v) within its specified volume ranges. It is not intended for use with highly corrosive, volatile organic solvents (e.g., chloroform, acetone), or high-density liquids (ρ > 1.2 g/mL) without prior validation. All models comply with ISO 8655-2:2022 for metrological performance, including gravimetric testing procedures for accuracy and precision. The device meets essential requirements for Good Laboratory Practice (GLP) and Good Manufacturing Practice (GMP) environments, supporting documented calibration records, user-defined maintenance logs, and traceable serial-number-based asset management. While inherently manual (non-electronic), it fully supports FDA 21 CFR Part 11-compliant workflows when integrated into validated SOPs that define operator training, calibration frequency, and tip compatibility matrices.

Software & Data Management

As a fully manual instrument, the Nichipet Air Multi-Channel Pipette does not incorporate embedded electronics or digital interfaces. Consequently, it generates no native electronic data streams, eliminating concerns related to firmware validation, cybersecurity, or software lifecycle management. This analog architecture aligns with laboratories prioritizing hardware-level reliability and regulatory transparency — especially in QC labs performing routine ELISA, PCR setup, or cell-based assays under ISO/IEC 17025 or CLIA frameworks. Calibration data, usage logs, and maintenance history are maintained externally via LIMS or paper-based records, ensuring full auditability without reliance on proprietary software platforms.

Applications

• High-throughput screening (HTS) plate preparation for drug discovery pipelines.
• Parallel sample dilution and standard curve generation in immunoassays (e.g., ELISA, MSD).
• qPCR and RT-qPCR reaction setup across 96-well and 384-well formats.
• Cell seeding and medium exchange in adherent and suspension cultures.
• Quality control testing in biopharmaceutical manufacturing, including fill-finish process validation support.

FAQ

Is the Nichipet Air series compatible with third-party pipette tips?
Yes — it accepts any ISO-standard conical tip (DN 100) with nominal inner diameter matching 0.5–300 µL volume classes. Performance validation is recommended for critical applications.
What is the recommended recalibration interval?
Per ISO 8655-5, initial calibration upon receipt, followed by quarterly verification under routine use; more frequent checks are advised after mechanical shock or exposure to extreme temperature/humidity cycles.
Can this pipette be used for reverse pipetting?
Yes — the adjustable plunger stop enables reliable reverse pipetting for viscous or foaming liquids, provided users follow validated technique protocols.
Does the device include a certificate of conformity?
Each unit ships with a factory-issued Declaration of Conformity referencing ISO 8655-2:2022 and JIS B 7902 compliance; optional NIST-traceable calibration certificates are available upon request.
How should the pipette be cleaned and sterilized?
Wipe external surfaces with 70% ethanol or isopropanol; never autoclave. Tip cones may be disassembled and cleaned ultrasonically in mild detergent; avoid immersion of the main body in liquid.
