Overview
The BRAND accu-jet® S Electric Pipette Controller (Model 26350) is an ergonomically engineered motorized pipetting aid designed for precise, repeatable, and fatigue-free handling of volumetric and graduated glass or plastic serological pipettes ranging from 0.1 mL to 200 mL. Unlike manual bulb or pump-based systems, the accu-jet® S operates on a brushless DC motor-driven vacuum principle—generating controllable negative pressure via an integrated, sealed air path—to enable accurate aspiration, dispensing, and blow-out functions across its full volume range. Its architecture adheres to ISO 8655-8 (pipette controllers) performance benchmarks and supports traceable liquid handling workflows in regulated environments where consistency, operator safety, and contamination control are critical—such as QC laboratories, bioprocessing facilities, and academic core facilities performing media preparation, cell culture maintenance, or reagent dilution.
Key Features
- Two-Mode Precision Control: Dual operational modes—Rapid (fixed high-speed aspiration) and Fine (pressure-sensitive variable-speed control)—allow users to fully fill a 25 mL pipette in ≤3 seconds or perform sub-microliter endpoint adjustments with fingertip pressure modulation.
- Ergonomic Single-Hand Operation: Balanced weight distribution, soft-grip textured housing, and strategically placed tactile buttons (aspirate, dispense, blow-out) eliminate wrist strain during extended use—validated per ISO 11228-3 guidelines for repetitive manual handling tasks.
- Integrated Liquid Protection System: A dual-stage barrier comprises a hydrophobic PTFE membrane filter (0.2 µm pore size) and a non-return silicone valve, preventing liquid ingress into the motor and electronics—even during accidental over-aspiration or tip immersion errors.
- Corrosion-Resistant Air Path Design: The internal airflow pathway contains no dead-volume chambers or moisture-trapping zones; vapor-free operation minimizes condensation risk and extends service life in humid or solvent-rich lab environments.
- Smart Rechargeable Power Management: High-capacity Li-ion battery supports ≥8 hours of continuous operation under typical usage (e.g., 50× 10 mL aspirations/hour). Dual-color LED indicator displays charge status; device remains fully functional while charging via included USB-C adapter.
- Bench-Friendly Rest Position: Integrated stable cradle allows the controller—with pipette inserted—to stand upright on the work surface without tipping, enabling hands-free pauses between sequential transfers.
Sample Compatibility & Compliance
The accu-jet® S is compatible with all standard Class A and Class B borosilicate glass pipettes (ISO 648, ISO 1042), polystyrene and polypropylene serological pipettes (including sterile, filtered, and low-retention variants), and reusable calibrated transfer pipettes. It meets CE marking requirements under the EU Medical Device Regulation (MDR 2017/745) Annex I essential requirements for non-invasive laboratory equipment. While not classified as a medical device, its design supports GLP-compliant documentation through consistent performance records and is routinely deployed in labs maintaining ISO/IEC 17025 accreditation. Filter cartridges comply with ASTM F2100 Level 3 fluid resistance standards.
Software & Data Management
As a standalone electromechanical instrument, the accu-jet® S does not feature embedded firmware, cloud connectivity, or digital data logging. However, its mechanical repeatability and defined accuracy specification (≤±0.5% at nominal volume) support integration into paper-based or LIMS-linked SOPs requiring documented pipetting parameters. Optional branded calibration certificates (traceable to NIST standards) are available upon request for audit readiness. Battery runtime logs and filter replacement intervals may be manually recorded in lab notebooks to satisfy FDA 21 CFR Part 11 “electronic record” expectations when used in GMP-regulated settings.
Applications
- Preparation and dispensing of culture media, buffers, and reagents in microbiology and cell biology labs
- High-volume serial dilutions in ELISA, PCR setup, and quality control testing
- Accurate filling of flasks, bottles, and reservoirs during upstream bioprocess development
- Safe handling of hazardous, viscous, or volatile liquids (e.g., organic solvents, acids, phenol-chloroform) where manual pipetting poses inhalation or splash risks
- Training environments—reducing learning curves for new technicians by eliminating variability inherent in thumb-controlled aspiration
FAQ
What pipette types and sizes is the accu-jet® S compatible with?
It supports all standard 0.1–200 mL glass and plastic serological pipettes meeting ISO 648 or ASTM E969 dimensional tolerances.
Is the device suitable for use with corrosive or organic solvents?
Yes—the sealed air path, PTFE filter, and chemically resistant housing materials (ABS + TPE) ensure safe operation with common lab solvents including ethanol, acetone, and diluted acids/bases.
How often should the filter cartridge be replaced?
Replace after every 500 mL of total aspirated volume or immediately following any visible liquid breakthrough; maximum interval is 3 months under light-use conditions.
Can the unit be sterilized or autoclaved?
No—autoclaving is prohibited. External cleaning only with 70% isopropanol or 10% bleach solution; never immerse in liquid.
Does BRAND provide calibration services for this model?
Yes—accredited third-party calibration with NIST-traceable documentation is available through authorized BRAND service centers in APAC and EMEA regions.
