IKA PETTE Manual Single-Channel Pipette

Overview

The IKA PETTE Manual Single-Channel Pipette is a precision-engineered liquid handling instrument designed for reproducible, traceable, and ergonomically optimized pipetting in regulated and research-intensive laboratory environments. Built upon the ISO 8655-6 standard for piston-operated volumetric apparatus, the PETTE series employs a gas-tight, low-friction piston system with a diamond-like carbon (DLC)-coated plunger — a surface treatment proven to reduce adhesion, minimize hysteresis, and extend service life under repeated chemical exposure. Unlike conventional air-displacement pipettes, the PETTE’s sealed drive mechanism ensures consistent aspiration and dispensing across viscosity gradients and temperature fluctuations, delivering accuracy within ±1% of nominal volume and precision below 0.5% coefficient of variation (CV) across its full 5–1000 µL range. Its modular architecture supports seamless integration into GLP/GMP workflows through factory-issued calibration certificates and compatibility with routine in-house verification protocols.

Key Features

• Ergonomic tri-grip system: Includes three user-swappable handles — soft-touch thermoplastic elastomer (TPE), micro-textured polymer, and low-thermal-conductivity composite — enabling optimal hand fit and minimizing thermal transfer from operator to pipette body.
• Large, bottom-aligned volume display: High-contrast engraved scale positioned at the base of the adjustment dial ensures parallax-free reading without repositioning the hand or wrist.
• Mechanical volume lock: Prevents accidental volume drift during transport, storage, or multi-step protocols requiring fixed dispensing volumes.
• Full autoclavability: Entire pipette assembly withstands standard steam sterilization cycles (121 °C, 20 min, 1 bar) without degradation of sealing integrity or metrological performance.
• DLC-coated conical tip interface and piston: Provides exceptional resistance to corrosion from organic solvents, dilute acids/bases, and oxidizing agents — critical for applications involving DMSO, ethanol, acetone, or sodium hypochlorite.
• Tool-free maintenance: Modular design allows complete disassembly, cleaning, and recalibration using only the included hex key — no specialized technicians or proprietary tools required.
• Intuitive multifunction button: Single actuation toggles between volume locking, fine-tuning, and tip ejection — reducing repetitive motion and improving workflow continuity.
• Color-coded volume identification: Each fixed-volume model (5–1000 µL) features standardized color bands aligned with international pipette coding conventions for rapid visual selection in shared lab environments.

Sample Compatibility & Compliance

The IKA PETTE pipette is validated for use with standard conical polypropylene tips (DNF/ISO 8655-compliant), low-retention tips, and filtered barrier tips. It maintains metrological stability when handling aqueous buffers, cell culture media, serum-containing solutions, and low-viscosity organic solvents (e.g., methanol, acetonitrile). All models are certified compliant with ISO 8655-2 (volumetric performance), ISO 8655-5 (calibration methods), and ISO 8655-6 (certification requirements). Factory calibration reports include uncertainty budgets traceable to national metrology institutes (PTB, Germany). The device meets mechanical durability requirements per ISO 8655-3 and is suitable for laboratories operating under FDA 21 CFR Part 11–aligned data integrity frameworks when paired with IKA’s optional calibration management software.

Software & Data Management

While the manual PETTE pipette operates independently of software, its calibration history and verification records integrate seamlessly into electronic lab notebook (ELN) systems via standardized CSV export from IKA’s free CaliSoft desktop application. CaliSoft supports audit-trail-enabled calibration logging, user access control, expiration alerts, and automatic generation of ISO/IEC 17025-compliant calibration certificates. All calibration events — including as-found/as-left data, environmental conditions, and technician signatures — are timestamped and digitally signed. The pipette’s physical design also facilitates barcode labeling for asset tracking within LIMS environments.

Applications

The PETTE single-channel pipette is routinely deployed in molecular biology (PCR setup, restriction digests, library preparation), clinical diagnostics (ELISA, immunoassays, sample dilution), pharmaceutical QC (potency testing, dissolution sampling), and academic research (cell transfection, metabolite extraction, microfluidic loading). Its low dead volume (<1 µL) and minimal carryover make it ideal for precious sample handling, while its robust construction ensures long-term reliability in high-throughput core facilities. Fixed-volume variants (e.g., PETTE fix 100 µL) are preferred for SOP-driven processes where volume consistency and operator error reduction are paramount.

FAQ

Is the entire pipette autoclavable?
Yes — all components, including seals and internal springs, are rated for full-cycle autoclaving at 121 °C, 20 minutes, 1 bar without performance loss.
Does it comply with ISO 8655 certification requirements?
Yes — each unit ships with a manufacturer-issued ISO 8655-6 calibration certificate, including measurement uncertainty, traceability statement, and environmental test conditions.
Can I recalibrate it in-house without external service?
Yes — the tool-free design and built-in adjustment screw allow full recalibration using a certified gravimetric method and analytical balance, following ISO 8655-5 guidelines.
What tip types are compatible?
Standard conical tips meeting ISO 8655-3 geometry specifications (DNF type), including low-retention, filtered, and extended-length variants.
How does the DLC coating improve longevity?
The diamond-like carbon layer reduces surface energy and wear on both the piston and tip cone, significantly extending functional lifespan in corrosive or high-cycle environments.
