Hirschmann Pipetus-Junior Rapid Manual Pipette

Overview

The Hirschmann Pipetus-Junior Rapid Manual Pipette is a precision-engineered single-channel liquid handling instrument designed for high-volume, repetitive manual pipetting tasks in regulated laboratory and production environments. Unlike conventional air-displacement pipettes—limited to volumes below 10 mL—the Pipetus-Junior operates on an optimized positive-displacement principle integrated with a high-efficiency piston-driven aspiration mechanism. This architecture enables accurate, consistent transfer of viscous, volatile, or temperature-sensitive liquids across its full 0.1–200 mL range without reliance on electronic components or external power sources. Its design addresses ergonomic fatigue commonly associated with bulk liquid handling, particularly during titration, buffer preparation, media dispensing, or QC sampling workflows where repeated use of glass or plastic volumetric pipettes introduces variability and operator strain.

Key Features

• Ergonomic, lightweight construction (130 g) minimizes hand and wrist fatigue during extended operation.
• Full autoclave compatibility: withstands repeated sterilization cycles at 121 °C / 2 bar for 20 minutes—validated per DIN EN 285 and ISO 17665—ensuring sterility maintenance in aseptic applications including cell culture and pharmaceutical manufacturing.
• Positive-displacement–enhanced aspiration delivers performance comparable to motorized pipettes in terms of speed and reproducibility, particularly for high-viscosity solutions (e.g., glycerol, agarose, serum-containing media).
• No battery or electrical components required—ideal for use in explosion-proof zones (ATEX Zone 2/22), cleanrooms with strict EMI control, or field laboratories lacking stable power infrastructure.
• Chemically resistant polyamide (PA 6.9) housing provides mechanical durability and resistance to common laboratory solvents, acids, and bases.
• Each unit is individually calibrated and certified; includes a traceable full-inspection quality report bearing a unique serial number—fully compliant with ISO 8655-3 requirements for verification documentation.

Sample Compatibility & Compliance

The Pipetus-Junior accommodates aqueous buffers, organic solvents, suspensions, and moderately viscous liquids (up to ~500 mPa·s) without significant deviation from nominal volume delivery. It is validated for use with standard conical or cylindrical receptacles, including volumetric flasks, titration vessels, bioreactor feed bags, and large-bore tubes. Regulatory alignment includes adherence to ISO 8655 (volumetric accuracy and precision standards for piston-operated pipettes), DIN EN ISO 9001 quality management system integration, and support for GLP/GMP audit readiness through documented calibration history and lot-specific certification. While not inherently compliant with FDA 21 CFR Part 11, its paper-based traceability package supports hybrid electronic record systems when paired with validated LIMS or ELN workflows.

Software & Data Management

As a fully manual device, the Pipetus-Junior does not incorporate embedded firmware, connectivity protocols, or onboard data logging. However, its serialized certification documentation is structured to integrate seamlessly into digital quality management systems (QMS). Each unit’s inspection report contains metrological parameters (aspiration/dispense accuracy, repeatability, linearity across five volume points), environmental test records (temperature/humidity stability), and signature-verified release by Hirschmann’s certified metrology lab. Laboratories may import these PDF reports directly into document control modules aligned with ISO 9000 or Annex 11-compliant validation frameworks.

Applications

• Titrations requiring rapid, repeatable delivery of standardized reagents (e.g., NaOH, HCl, EDTA) into burettes or reaction vessels.
• Preparation of culture media, fermentation feeds, or dilution series in microbiology and bioprocessing labs.
• QC sampling and bulk transfer in pharmaceutical manufacturing under GMP conditions.
• Environmental testing labs handling soil extracts or wastewater samples where solvent exposure precludes electronic instrumentation.
• Educational settings emphasizing hands-on technique development with real-world volume ranges beyond typical benchtop pipettes.

FAQ

Is the Pipetus-Junior suitable for sterile applications?
Yes—its fully autoclavable construction (121 °C, 20 min) and absence of seals or lubricants susceptible to thermal degradation ensure sustained sterility assurance in aseptic processes.
How is accuracy verified across the 0.1–200 mL range?
Per ISO 8655-3, each unit undergoes gravimetric verification at five defined volume points (0.1, 1, 10, 100, and 200 mL) using Class A analytical balances traceable to national standards.
Can it be used with corrosive solvents like concentrated HNO₃ or acetone?
The PA 6.9 body exhibits broad chemical resistance; however, prolonged exposure to strong oxidizers or halogenated solvents is not recommended—consult Hirschmann’s chemical compatibility chart prior to deployment.
Does it require routine recalibration?
No scheduled recalibration is mandated, but periodic user verification (e.g., daily or per-shift gravimetric checks) is advised in GLP/GMP environments to maintain documented measurement confidence.
Is there a service program available for international users?
Hirschmann-certified service centers operate globally; all repairs and recalibrations follow ISO/IEC 17025-accredited procedures with full traceability documentation.
