Overview
The RAININ BenchSmart™ 96 Semi-Automatic 96-Channel Pipetting System is an engineered solution for high-throughput, precision liquid handling in life science laboratories. Unlike fully automated robotic workstations or manual multichannel pipettes, the BenchSmart 96 operates on a semi-automatic principle—combining motorized actuation with user-directed workflow control via an integrated capacitive touchscreen interface. Its core architecture leverages positive-displacement and air-displacement pipetting principles, optimized per tip range to ensure volumetric fidelity across its full 0.5–1000 µL span. Designed specifically for 96-well and 384-well microplate formats, the system supports standardized SBS footprint compliance and integrates seamlessly into existing lab workflows without requiring dedicated robotics infrastructure or extensive validation overhead.
Key Features
- Three interchangeable pipetting heads—calibrated for distinct volume ranges: 0.5–20 µL (low-volume precision), 20–200 µL (routine assay preparation), and 100–1000 µL (bulk reagent transfer and purification workflows)
- Capacitive touchscreen interface with intuitive icon-driven navigation—enabling one-touch execution of preloaded protocols or real-time parameter adjustment
- Seven programmable pipetting modes: Basic Pipetting, Advanced Mode (user-defined step sequencing), Serial Dilution, Continuous Dispensing, Reverse Pipetting, Variable Volume Transfer (Sequence Range), and Mix/Repeat Cycles
- Integrated tip loading and ejection mechanism—reducing operator-induced variability and minimizing repetitive strain injury (RSI) risk
- Four-reservoir well layout support—optimizing deck space usage and reducing tip and source plate changes; enables dual-solution transfer in as few as four pipetting actions versus nine on conventional two-deck systems
- Motor-driven vertical Z-axis control with adjustable speed profiles—ensuring consistent tip immersion depth and blow-out dynamics across viscosity gradients
Sample Compatibility & Compliance
The BenchSmart 96 accommodates standard ANSI/SBS-compliant 96-well and 384-well plates—including PCR plates, cell culture plates, ELISA strips, and deep-well storage plates—as well as universal reservoirs and tube racks (up to 15 mL conical format). All pipetting heads are certified for use with RAININ LTS (Low Retention Tips) and compatible third-party filtered tips meeting ISO 8655-2 specifications. The system complies with IEC 61000-4 electromagnetic compatibility standards and meets UL/CSA safety requirements for laboratory equipment. While not classified as GMP-grade instrumentation, its repeatable performance, audit-ready protocol logging, and traceable calibration records support GLP-aligned workflows and internal QC documentation per ISO/IEC 17025 Annex A.5 guidelines.
Software & Data Management
The onboard firmware supports protocol creation, modification, and storage directly via the touchscreen—no external PC required for routine operation. Each protocol retains metadata including date/time stamp, operator ID (optional login), tip type used, and executed volume parameters. Exportable CSV logs capture cycle-by-cycle aspiration/dispense events for post-run analysis. For labs operating under regulated environments (e.g., clinical diagnostics or pharmaceutical development), the system can be integrated into broader LIMS or electronic lab notebook (ELN) ecosystems via USB mass storage mode or optional RS-232 serial output. Though not natively compliant with FDA 21 CFR Part 11, its deterministic behavior, non-volatile memory retention, and immutable log timestamps facilitate alignment with ALCOA+ data integrity principles when deployed within validated SOP frameworks.
Applications
- High-throughput screening (HTS) assay setup—including cell-based assays, enzymatic activity profiling, and receptor binding studies
- Genomic workflow support: cDNA synthesis, qPCR master mix preparation, NGS library normalization, and CRISPR guide RNA complexing
- Proteomics sample prep: buffer exchange, desalting, and fraction collection from spin columns or 96-well filter plates
- Quality control testing in biomanufacturing: potency assay dilution series, reference standard preparation, and stability-indicating method transfers
- Educational and core facility use—where ease of training, low maintenance burden, and cross-user reproducibility are prioritized over full automation scalability
FAQ
Is the BenchSmart 96 considered a fully automated liquid handler?
No—it is a semi-automatic system requiring operator initiation of each step but eliminating manual plunger actuation and tip handling.
Can it be used with 384-well plates?
Yes, when equipped with the optional 384-well head adapter and corresponding tip configuration.
Does it support calibration verification per ISO 8655?
Yes—each pipetting head includes a documented calibration certificate traceable to NIST standards; users may perform periodic gravimetric verification using certified weights and Class A volumetric glassware.
What file formats does it support for protocol import/export?
Protocols are stored internally in proprietary binary format; export is limited to timestamped CSV logs of execution history.
Is remote monitoring or network connectivity available?
No native Ethernet or Wi-Fi capability exists; connectivity is restricted to USB host/device and RS-232 serial interfaces.
