Overview
The Hopebio GHLF100-1 Smart Tube Dispenser is a compact, benchtop liquid handling system engineered for high-reproducibility reagent dispensing into diverse tube formats—including standard glass test tubes, centrifuge tubes, cryovials, and clinical sample collection tubes. It operates on a precision-controlled peristaltic pumping principle, where calibrated rotational displacement of flexible tubing delivers consistent volumetric output without fluid contact with moving mechanical parts. Designed for routine QC labs, clinical diagnostics support units, and academic core facilities, the GHLF100-1 bridges the gap between manual pipetting and full-scale robotic liquid handlers—offering walk-away automation for repetitive tube-filling tasks while maintaining traceable, operator-independent dispensing performance.
Key Features
- Peristaltic pump-driven dispensing with adjustable flow rate and programmable volume per dispense (range: 0.1–50 mL, typical resolution ±1% CV at ≥1 mL)
- High-speed parallel processing: up to 100 tubes per batch, configurable via user-defined tube rack templates
- Modular tube rack compatibility: supports standardized dimensions including 12×75 mm (100-position), 15×150 mm (90- or 100-position), and 18×180 mm (81-position); custom rack integration available upon specification
- Integrated safety interlock system: real-time proximity sensing halts motion and triggers audible/visual alarm upon unintended physical contact during operation
- 10.1-inch capacitive touchscreen interface with intuitive icon-based workflow navigation; no external PC required for basic operation
- One-touch calibration protocol: automatic pump priming and volume verification using gravimetric or volumetric reference standards
- Dedicated cleaning cycle: programmable flush duration and rinse volume for silicone tubing, minimizing carryover and enabling rapid reconfiguration between reagents
- Flexible batch control: discrete tube count setting (1–100) with pause/resume functionality and end-of-batch notification
Sample Compatibility & Compliance
The GHLF100-1 accommodates tubes with outer diameters from 8 mm to 18 mm and heights up to 180 mm. Its adaptive gripper mechanism and height-adjustable dispensing nozzle ensure stable alignment across heterogeneous tube types without mechanical modification. The system complies with IEC 61000-6-2 (EMC immunity) and IEC 61000-6-4 (EMC emission) standards. While not certified as medical device hardware, its design supports GLP-compliant documentation practices: all dispense parameters (volume, tube count, timestamp, operator ID) are logged locally and exportable in CSV format. Optional audit trail extension enables alignment with FDA 21 CFR Part 11 requirements when integrated with validated LIMS environments.
Software & Data Management
The embedded firmware provides standalone operation with persistent parameter storage (≥100 user-defined protocols). Protocol files include dispensing volume, tube count, rack type, and cleaning sequence settings. Data export occurs via USB 2.0 port; no cloud connectivity or remote access capability is implemented—ensuring data sovereignty and network isolation per institutional IT policy. For laboratories requiring electronic record integrity, the system supports optional integration with third-party ELN platforms via RS-232 serial output (ASCII command set available under NDA).
Applications
- Preparation of standardized dilution series for ELISA, PCR master mix assembly, and microbiological media aliquoting
- High-throughput filling of diagnostic sample collection kits (e.g., saliva, blood spot, or nasal swab tubes)
- QC sample distribution for stability studies and reference material packaging
- Automated loading of tubes for downstream automation (e.g., integration with tube decappers, barcode readers, or centrifuges)
- Support of ISO/IEC 17025-accredited testing workflows where manual dispensing introduces unacceptable variability
FAQ
What tube dimensions does the GHLF100-1 support out of the box?
Standard configurations include racks for 12×75 mm (100-tube), 15×150 mm (90- or 100-tube), and 18×180 mm (81-tube) formats. Custom rack designs can be commissioned for non-standard geometries.
Is the peristaltic pump tubing autoclavable?
The silicone tubing supplied meets USP Class VI biocompatibility but is not rated for repeated autoclaving; replacement intervals are recommended every 500–1,000 dispense cycles depending on reagent corrosivity.
Can the instrument be validated for GMP environments?
Yes—IQ/OQ documentation packages are available upon request, including pump linearity verification, dispensing repeatability reports (n=3×10 replicates per volume), and touchscreen input response validation.
Does the system support barcode-triggered dispensing?
Not natively; however, the RS-232 interface allows external barcode scanner integration for conditional protocol execution in custom automation setups.
What maintenance is required beyond tubing replacement?
Monthly visual inspection of nozzle alignment and gripper actuator smoothness; annual calibration verification using NIST-traceable graduated cylinders or analytical balances is advised.
