Overview
The DLAB HiPette 8-Channel Adjustable Manual Pipette is an ergonomically engineered precision liquid handling instrument designed for high-throughput, multi-well plate workflows in life science and analytical laboratories. Operating on the air displacement principle, it delivers consistent volumetric delivery across all eight channels simultaneously—enabling reproducible transfer of aqueous and low-viscosity solutions into 96-well or 384-well microplates. Its fully autoclavable construction (121 °C, 20 min, saturated steam) supports strict aseptic protocols required in cell culture, molecular diagnostics, and GLP-compliant assay development. Unlike fixed-volume multichannel pipettes, the HiPette offers continuous adjustability within four discrete volume ranges, allowing users to maintain optimal accuracy across diverse experimental scales—from sub-microliter PCR setup to 300 μL reagent dispensing.
Key Features
- Ergonomic lightweight design with contoured grip and optimized center-of-mass distribution—reduces operator hand fatigue during extended pipetting sessions (validated per ISO 7250-1 anthropometric guidelines).
- Color-coded volume range identification system (e.g., yellow for 0.5–10 μL, blue for 30–300 μL), enabling rapid visual differentiation without label reading.
- Dual-stage volume lock mechanism prevents accidental adjustment during plate handling or transport—critical for maintaining calibration integrity between runs.
- Four-digit digital volume display with 0.001 μL resolution provides real-time feedback; digits remain legible under standard lab lighting and hood illumination.
- 360° freely rotating tip ejector lever accommodates varied benchtop orientations and ergonomic wrist positioning—minimizing repetitive strain risk.
- Spring-assisted tip attachment technology ensures uniform seal pressure across all eight channels with single-light-touch engagement—eliminating need for excessive downward force or “tapping”.
- Full-body autoclavability (including plunger assembly and tip cone) complies with ISO 13485 medical device sterilization requirements; also compatible with UV-C (254 nm) exposure for surface decontamination.
Sample Compatibility & Compliance
The HiPette 8-channel pipette is validated for use with standard conical polypropylene tips (DNase/RNase-free, low-retention, filter-equipped options recommended). It maintains performance consistency with aqueous buffers (PBS, Tris-HCl), ethanol/water mixtures (15%), volatile (e.g., chloroform), or corrosive liquids (e.g., strong acids/bases). Complies with ISO 8655-2:2022 (volumetric accuracy testing), ISO 8655-5:2022 (gravimetric verification procedures), and supports traceable calibration per ISO/IEC 17025 requirements. Meets essential safety provisions of IEC 61010-1 for laboratory equipment.
Software & Data Management
As a manual mechanical pipette, the HiPette does not incorporate embedded electronics or connectivity features. However, its design facilitates integration into regulated environments: volume settings are mechanically recorded via engraved scale indicators; calibration logs—including date, technician ID, and gravimetric test results—can be maintained in paper or LIMS-compatible electronic formats. For labs operating under FDA 21 CFR Part 11 or EU Annex 11, the instrument’s passive architecture eliminates software validation burden while supporting audit-ready documentation of maintenance history, sterilization cycles, and periodic verification records.
Applications
- High-throughput screening (HTS): Parallel dispensing into microplates for cytotoxicity assays, reporter gene assays, and dose-response profiling.
- Molecular biology: Simultaneous setup of 8× PCR/qPCR reactions, cDNA synthesis arrays, and restriction digestion plates.
- Immunoassays: Uniform coating and detection reagent addition in ELISA, MSD, and lateral flow assay development.
- Cell-based assays: Seeding of adherent or suspension cells across multiwell plates with minimized well-to-well variability.
- Quality control testing: Replicate sample preparation for HPLC, LC-MS, or spectrophotometric analysis where inter-channel consistency directly impacts CV%.
FAQ
Is the entire pipette body autoclavable?
Yes—the complete unit, including internal piston assembly and tip cone, is rated for repeated autoclaving at 121 °C for 20 minutes under saturated steam conditions.
What tip types are compatible?
Standard universal-fit conical tips (10–300 μL nominal capacity); compatibility confirmed with major OEM and third-party low-binding, filtered, and sterile options.
How often should calibration be performed?
DLAB recommends initial calibration upon receipt, after any impact or disassembly, and at least every 3–6 months in routine use—aligned with ISO 8655-6 frequency guidance.
Does the pipette support GLP/GMP documentation?
Yes—its mechanical design enables straightforward generation of calibration certificates, sterilization logs, and usage records compliant with GLP Annexes and GMP Annex 15 expectations.
Can individual channels be adjusted independently?
No—volume is set uniformly across all eight channels; this ensures inter-channel consistency and simplifies SOP adherence in regulated workflows.
