Overview
The BIO-DL Genex-1 Multi-Channel Pipette is an engineered solution for high-throughput liquid handling in molecular biology, clinical diagnostics, and quality control laboratories. Designed around precision volumetric displacement principles—consistent with ISO 8655-2 (piston-operated volumetric apparatus)—the Genex-1 delivers reproducible delivery across its full operational range (0.5 µL to 1000 µL) without requiring recalibration between volume settings. Its modular architecture integrates a corrosion-resistant polymer piston and an asymmetric O-ring sealing system to minimize dead volume, reduce carryover risk, and maintain long-term accuracy under repeated thermal and mechanical stress. Unlike single-channel alternatives, the Genex-1 enables parallel transfer of identical volumes into multi-well plates (e.g., 96-well or 384-well formats), directly supporting workflows such as nucleic acid extraction, ELISA setup, PCR master mix preparation, and cell culture passaging.
Key Features
- Ergonomic handle with textured anti-slip grip pattern—optimized for extended use and reduced operator fatigue during repetitive pipetting cycles
- 360° rotatable multi-tip interface—enables flexible positioning for angled plate access and improved alignment with well geometry
- Lightweight construction using high-tensile thermoplastic elastomer—resistant to autoclaving (up to 121°C, 20 min), chemical exposure (including 70% ethanol, dilute acids/bases), and mechanical abrasion
- Universal tip compatibility—mechanically and dimensionally aligned with ISO 8655-3 specifications for conical tip interfaces; validated with tips from Eppendorf, Gilson, Thermo Fisher, and Rainin
- Modular channel configuration—available in 8-, 12-, and 48-channel variants to match common microplate layouts and throughput requirements
- Tool-free maintenance design—piston assembly and seal components are accessible without disassembly tools, facilitating routine cleaning and verification per GLP-compliant lab SOPs
Sample Compatibility & Compliance
The Genex-1 is validated for aqueous solutions, buffers, diluted organic solvents (e.g., ≤10% isopropanol in PBS), and viscous biological matrices including serum, plasma, and lysates—provided viscosity remains below 10 mPa·s at 20°C. It complies with ISO 8655-2 (volumetric accuracy), ISO 8655-5 (repeatability testing protocols), and EN ISO/IEC 17025:2017 requirements for measurement traceability when used with certified reference standards. While not FDA 21 CFR Part 11–validated out-of-the-box, the device supports audit-ready documentation when integrated with compliant LIMS or electronic lab notebook (ELN) systems that record operator ID, date/time stamps, and calibration history.
Software & Data Management
The Genex-1 operates as a standalone mechanical instrument with no embedded firmware or digital interface. However, its consistent mechanical performance enables reliable integration into automated workflows via third-party liquid handling platforms (e.g., Tecan Freedom EVO, Hamilton STAR). For manual operation, users may document usage logs, calibration events, and maintenance records using standardized templates aligned with ISO/IEC 17025 Annex A.3 and CLSI EP15-A3 guidelines. Traceable calibration certificates can be generated using gravimetric methods per ISO 8655-6, with uncertainty budgets calculated according to EURACHEM/CITAC Guide CG4.
Applications
- Nucleic acid isolation workflows—simultaneous addition of lysis buffer, binding solution, and wash reagents to deep-well plates
- High-throughput screening (HTS)—uniform dispensing of assay reagents into 384-well plates for drug discovery pipelines
- Quality assurance in biomanufacturing—preparation of reference standard dilutions for HPLC or UV-Vis quantification
- Vaccines and diagnostics development—replicate sample distribution for antigenicity or sensitivity testing
- Academic research labs—efficient setup of dose-response curves, CRISPR transfection mixes, or microbiological susceptibility panels
FAQ
Is the Genex-1 suitable for handling viscous or volatile liquids?
Yes—within defined limits. Accuracy is maintained for liquids up to 10 mPa·s viscosity (e.g., glycerol solutions <15% v/v); for volatile solvents (e.g., acetone, chloroform), reverse pipetting technique is recommended.
Can the Genex-1 be sterilized in an autoclave?
The lower body (tip cone and piston housing) withstands standard autoclaving cycles (121°C, 15–20 min, saturated steam); however, the upper handle assembly should be wiped with 70% ethanol only.
What calibration frequency is recommended?
Per ISO 8655-6, quarterly verification is advised for routine QC use; monthly checks are required in regulated environments (e.g., GMP labs performing release testing).
Does it support positive displacement tips?
No—the Genex-1 is air-displacement only and is not compatible with positive displacement tip systems.
How is tip ejection force controlled?
A dual-stage mechanical ejection lever provides adjustable pressure: light press for standard tips; firm press for high-retention or filter tips.
