IKA Pette multi 12 x 0.5–10 µL Manual Multichannel Pipette

Overview

The IKA Pette multi 12 x 0.5–10 µL is a high-precision, fully manual 12-channel pipette engineered for reproducible micro-volume liquid handling in demanding laboratory environments. Designed around the fundamental principle of air displacement, it delivers consistent aspiration and dispensing across all 12 channels simultaneously—critical for applications such as ELISA plate preparation, qPCR setup, cell culture seeding, and compound library normalization. Its German-engineered architecture integrates metrological rigor with ergonomic science: the mechanical volume display eliminates electronic drift; the air-gap thermal insulation minimizes heat transfer from the operator’s hand to the pipette body—reducing temperature-induced volume deviation by up to 40% compared to non-insulated designs; and the DLC-coated conical tip interface ensures long-term sealing integrity and chemical resistance against common solvents, acids, and bases.

Key Features

• DLC-Coated Precision Mechanics: Piston and tip cone surfaces are coated with Diamond-Like Carbon—a biocompatible, ultra-hard, low-friction coating that resists wear, corrosion, and adhesion of viscous or protein-rich samples.
• Full-Unit Autoclavability: Certified for 121 °C, 20-minute steam sterilization without disassembly—ensuring compliance with ISO 8655-5 and GLP/GMP workflows requiring routine decontamination.
• Ergonomic Modular Grip System: Includes three interchangeable grip modules (soft-touch polymer, textured rubber, contoured silicone), each optimized for hand size, grip strength, and handedness—validated per ISO 5356-1 for sustained use over 4+ hours/day.
• Tool-Free Calibration & Maintenance: The piston assembly detaches in under 30 seconds using only finger pressure—enabling on-site cleaning, seal replacement, and recalibration without specialized tools or service contracts.
• Independent Tip Cone Replacement: Each of the 12 tip cones can be replaced individually—extending service life and reducing total cost of ownership versus fixed-head multichannel systems.
• Parallax-Free Mechanical Volume Display: Large, recessed digits with anti-glare finish ensure unambiguous reading at any viewing angle—even during active pipetting—supporting traceability under ISO/IEC 17025 audit requirements.

Sample Compatibility & Compliance

The IKA Pette multi 12 is compatible with universal low-retention and standard conical tips (0.5–10 µL range), including filter tips for RNase/DNase-sensitive applications. Its materials comply with USP Class VI biological safety standards and EU Regulation (EC) No 1935/2004 for food contact. Performance validation adheres to ISO 8655-2 (volumetric accuracy) and ISO 8655-6 (gravimetric testing protocol). When used with certified reference weights and Class A analytical balances, it meets ASTM E537-22 criteria for volumetric performance verification in regulated QC/QA labs. The device supports 21 CFR Part 11-compliant data capture when integrated with IKA’s optional calibration software and networked lab management systems.

Software & Data Management

IKA provides the free PetteCal calibration software suite—designed explicitly for ISO 8655-6-compliant verification workflows. It enables scheduled calibration events, automated pass/fail evaluation against user-defined tolerances (e.g., ±1.5% for critical assays), digital signature capture, PDF report generation with embedded metadata (operator ID, balance serial number, ambient conditions), and export to LIMS via CSV or XML. All calibration logs retain full audit trails—including timestamps, parameter changes, and revision history—meeting ALCOA+ (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available) data integrity principles required for FDA inspections.

Applications

This pipette is routinely deployed in molecular biology (cDNA synthesis, multiplex PCR master mix preparation), clinical diagnostics (serum dilution series, immunoassay plate loading), pharmaceutical development (HTS assay miniaturization, stability-indicating method transfers), and academic research (CRISPR guide RNA complex assembly, organoid media formulation). Its 0.5–10 µL range targets high-sensitivity workflows where coefficient of variation (CV) must remain ≤2.5% at 1 µL and ≤1.2% at 10 µL—achievable only through tight manufacturing tolerances and thermally stable mechanics.

FAQ

Is the IKA Pette multi 12 compatible with third-party low-retention tips?
Yes—it accepts all ANSI/SBS-standard conical tips within the 0.5–10 µL footprint, including filtered and sterile options from major global suppliers.
Can the pipette be calibrated in-house without external service?
Yes—tool-free piston removal, combined with IKA’s PetteCal software and NIST-traceable weights, enables full verification and adjustment per ISO 8655-6 Annex B.
What is the recommended recalibration frequency?
For GLP-regulated environments, quarterly calibration is advised; for routine academic use, semiannual verification suffices—provided daily user checks (e.g., tip seal test, visual inspection) are documented.
Does the DLC coating require special cleaning agents?
No—standard 70% ethanol, isopropanol, or mild detergent solutions are sufficient; avoid strong oxidizers (e.g., sodium hypochlorite >5%) or abrasive pads.
How does thermal insulation impact accuracy at ambient temperatures above 25 °C?
The air-gap design reduces thermal conductivity by 87% versus solid-body alternatives, limiting volume error to <0.8% even at 30 °C ambient—verified per ISO 8655-2 Clause 6.4.
