DLAB MicroPette Plus Fully Autoclavable Adjustable Manual Pipette

Overview

The DLAB MicroPette Plus is a high-precision, fully autoclavable manual pipette engineered for reproducible liquid handling across academic, clinical, and industrial laboratories. Designed around the fundamental principles of air displacement volumetric measurement, the MicroPette Plus delivers consistent aspiration and dispensing performance across its broad volume range—from ultra-low volumes (0.1 µL) to high-capacity transfers (5000 µL). Its robust stainless-steel and chemically resistant polymer construction ensures long-term dimensional stability under repeated sterilization cycles, while the integrated ergonomic architecture minimizes operator fatigue during high-throughput workflows. Unlike disposable or semi-disposable alternatives, the MicroPette Plus is built as a serviceable precision instrument—capable of full recalibration and component-level maintenance using standardized tools and documented procedures.

Key Features

• Ergonomic design with low-force plunger activation and extended finger rest for reduced hand strain during extended use
• Full autoclavability at 121 °C, 1 bar for 20 minutes—no disassembly required; also compatible with UV-C irradiation (254 nm) and exposure to common laboratory disinfectants (e.g., 70% ethanol, 0.5% sodium hypochlorite)
• Digitally indexed volume adjustment with large, glare-free display window—enabling rapid, parallax-free reading of setpoint values
• Modular construction with field-replaceable piston, seal, and tip ejector assemblies—supporting in-lab calibration and repair per ISO 8655-6 guidelines
• Multi-channel variants (8- and 12-channel) optimized for 96-well microplate compatibility, featuring synchronized tip ejection and independent channel volume locking
• Fixed-volume models available for critical applications requiring zero user-set variability (e.g., reagent dispensing, QC standards preparation)

Sample Compatibility & Compliance

The MicroPette Plus is validated for use with aqueous solutions, buffers, organic solvents (including acetonitrile, methanol, and DMSO), and viscous reagents (up to 50 cP). Its PTFE-coated internal surfaces and fluoropolymer seals resist adsorption and degradation, ensuring minimal carryover and long-term accuracy retention. All models comply with ISO 8655 Parts 1–6 (Piston-operated Volumetric Apparatus), and are certified to ISO 9001:2008 (Quality Management Systems) and ISO 13485:2003 (Medical Device Quality Management). Documentation packages include factory calibration certificates traceable to NIM (National Institute of Metrology, China) standards, supporting GLP and GMP audit readiness. While not FDA 21 CFR Part 11–compliant out-of-the-box (as a standalone mechanical device), its calibration logs and service records meet ALCOA+ data integrity principles when maintained manually or via DLAB’s optional web-based calibration portal.

Software & Data Management

DLAB provides a free, browser-based calibration management platform accessible via registered account. Users may upload calibration results, generate PDF-certified reports, schedule maintenance intervals, and archive historical performance data—including accuracy and precision verification at three volume points (10%, 50%, and 100% of nominal range). The system supports CSV export for integration into LIMS or ELN environments. No proprietary software installation is required; all calibration workflows adhere to ISO/IEC 17025–recommended uncertainty estimation methods, incorporating repeatability, temperature drift, and operator influence factors. Firmware updates for future smart-capable accessories (e.g., Bluetooth-enabled volume logging modules) are delivered through the same portal.

Applications

The MicroPette Plus serves as a foundational tool in molecular biology (PCR setup, restriction digests, library prep), clinical diagnostics (ELISA, immunoassays, sample dilution), pharmaceutical QA/QC (standard curve preparation, dissolution testing), and environmental testing (extraction solvent dosing, wastewater spike recovery). Its low-volume capability (0.1–2.5 µL range) supports single-cell genomics workflows, while the 1000–5000 µL configurations enable bulk buffer preparation and cell culture media dispensing. Multi-channel variants significantly reduce inter-well variability in high-content screening assays and CRISPR gRNA transfection experiments—where tip-to-tip consistency directly impacts statistical power and assay reproducibility.

FAQ

Is the entire pipette body compatible with standard steam autoclaving cycles?
Yes—fully assembled units withstand 121 °C, 103 kPa (15 psi), 20-minute cycles without seal deformation or calibration shift. Post-autoclave verification at three volume points is recommended before resuming critical work.
Can I perform in-house calibration without sending the unit to a service center?
Yes—DLAB supplies ISO 8655–compliant calibration kits (gravimetric balance, Class A distilled water, temperature-controlled environment protocol) and step-by-step video guides. Calibration records must document ambient temperature, humidity, water density correction, and repeatability (n ≥ 10).

What is the expected service life under routine lab use?
With biannual preventive maintenance and proper handling, typical service life exceeds 10 years. Piston wear is monitored via plunger resistance and tip ejection force; replacement kits extend functional longevity beyond OEM warranty periods.

Are spare parts and consumables available globally?
Yes—DLAB maintains regional distribution hubs in North America, EMEA, and APAC. All components (seals, springs, plungers, tip ejectors) are cataloged with universal part numbers and shipped with lot-specific traceability documentation.

Does DLAB offer training for multi-user labs?
Yes—certified application specialists deliver virtual or on-site workshops covering ISO 8655 compliance, ergonomic technique, error source analysis, and audit-ready recordkeeping. Training materials align with CLSI EP15-A3 and EUROLAB Technical Guide No. 08/2021.
