Overview
The IKA Pette Multi 12-channel manual pipette is a precision-engineered liquid handling instrument designed for high-throughput, reproducible dispensing across 12 parallel channels in microtiter plates, deep-well plates, and other multi-well formats. Based on positive displacement air-cushion technology, it delivers consistent volumetric accuracy and repeatability within ISO 8655-compliant tolerances—specifically ±0.8 % relative error and ±1.6 µL absolute error at the 200 µL setting. Engineered in Germany and manufactured to stringent DIN EN ISO 9001 quality standards, this pipette integrates ergonomic functionality with metrological reliability for routine QC, assay development, ELISA, cell culture seeding, and nucleic acid workflows where inter-operator variability must be minimized.
Key Features
- Ergonomic tri-grip system: Interchangeable handles in three distinct shapes and materials accommodate left- and right-handed users, as well as varying hand sizes—reducing grip force by up to 40 % compared to conventional designs.
- DLC-coated conical tip and piston: Diamond-like carbon (DLC) coating ensures long-term chemical resistance against ethanol, DMSO, acetonitrile, and common lab solvents, while minimizing friction and wear over >100,000 pipetting cycles.
- Air-gap thermal isolation: Dual-layer housing incorporates an insulating air cavity between the outer shell and internal mechanism, preventing heat transfer from the operator’s hand and mitigating temperature-induced volume drift (critical for viscous or temperature-sensitive samples).
- Tool-free calibration & maintenance: Full disassembly of the piston/seal assembly requires only three steps—no specialized tools needed. Each of the 12 cone tips is independently replaceable, extending service life and reducing total cost of ownership.
- Single-hand volume adjustment: A coaxial rotary dial allows precise, tactile volume setting without repositioning the hand; volume lock prevents accidental changes during plate handling or transport.
- Mechanical large-digit display: High-contrast, non-electronic volume readout with oversized numerals remains legible during active pipetting—even at oblique viewing angles or under low-light hood conditions.
Sample Compatibility & Compliance
The IKA Pette Multi supports universal compatibility with standard conical tips (including low-retention, filtered, and sterile options) and maintains performance across aqueous buffers, serum-containing media, glycerol solutions (<30 % v/v), and diluted organic solvents. All models are certified for autoclaving at 121 °C / 2 bar for 20 minutes (full-instrument sterilization supported per IKA PETTE fix/vario/multi design). Device conformity includes CE marking per Directive 2014/30/EU (EMC) and 2014/35/EU (LVD), and compliance with ISO 8655-2 (volumetric performance), ISO 8655-5 (calibration), and ISO 13485 (medical device QMS). Documentation supports GLP/GMP audit readiness, including traceable serial-number-based calibration records.
Software & Data Management
IKA provides proprietary calibration management software compatible with Windows 10/11, enabling scheduled calibration planning, automated data capture from gravimetric tests (ASTM E542, ISO 8655-6), and electronic signature support per FDA 21 CFR Part 11 requirements. Calibration reports include uncertainty budgets, environmental condition logging (temperature/humidity), and pass/fail status against user-defined acceptance criteria. The software interfaces natively with IKA’s robotic calibration platforms “Pit” and “Patty”, which perform fully automated, ISO/IEC 17025-aligned verification of all 12 channels simultaneously—including tip ejection force validation and seal integrity diagnostics.
Applications
This 12-channel pipette is routinely deployed in pharmaceutical QC labs for dissolution testing sample preparation, clinical diagnostics for multiplex immunoassays, academic genomics cores for PCR master mix distribution, and biomanufacturing environments for upstream process sampling. Its 20–200 µL range makes it especially suited for applications requiring intermediate-volume precision—such as serial dilution in 96-well plates, protein concentration normalization prior to SDS-PAGE, and high-density cell plating in stem cell differentiation studies. The mechanical design eliminates battery dependency and electromagnetic interference concerns common in sensitive electrophysiology or imaging setups.
FAQ
Is full-instrument autoclaving supported?
Yes—the entire pipette body, including piston, spring, and tip cones, is rated for repeated autoclaving at 121 °C / 2 bar for 20 minutes.
Does the pipette comply with ISO 8655 calibration standards?
Yes—each unit ships with a factory calibration certificate traceable to PTB (Physikalisch-Technische Bundesanstalt), and the included software enables full ISO 8655-5 compliant recalibration.
Can individual channels be serviced without affecting others?
Yes—each of the 12 conical tips mounts independently; worn or contaminated tips can be replaced without disassembling adjacent channels.
What is the recommended recalibration interval under GLP conditions?
Per ISO 8655-5 and typical laboratory SOPs, recalibration is advised every 3–6 months, or after 10,000 pipetting cycles, whichever occurs first.
Is the volume display readable during active pipetting?
Yes—the mechanical, high-contrast digit display is positioned for direct line-of-sight visibility without requiring wrist rotation or device reorientation.
