Overview
The Thermo Scientific FH100D and FH100DX peristaltic dispensing pumps are engineered for precision liquid handling in regulated laboratory, quality control, and pilot-scale manufacturing environments. Based on positive displacement via roller compression of elastomeric tubing, these pumps deliver contamination-free fluid transfer—ideal for reagents, buffers, cell culture media, and other sensitive or corrosive liquids where wetted-path integrity is critical. Unlike diaphragm or piston-based systems, the FH100D/DX architecture ensures zero contact between the drive mechanism and process fluid, eliminating risk of lubricant ingress, seal degradation, or cross-contamination. Designed for long-term operational stability, the brushless DC motor and hardened gear train support continuous duty cycles with minimal drift in flow accuracy over time.
Key Features
- Quick-release pump head enabling tube replacement in under 30 seconds—reducing downtime during routine maintenance or protocol changes.
- Dynamic, tube-size-specific calibration: each tubing inner diameter is assigned a unique calibration factor stored in non-volatile memory, ensuring reproducible volumetric accuracy across multiple tube sizes without manual recalibration.
- Three programmable dispensing modes: volume-based (µL to mL), time-based (ms to hours), and cycle-based with user-defined inter-cycle delays—enabling complex multi-step protocols such as sequential reagent addition or gradient dilution.
- Reversible flow direction supports pre-dispense tube priming and post-run flushing—critical for preventing carryover in high-value assays or GMP-compliant processes.
- Digital RPM display provides real-time rotational speed feedback, allowing operators to correlate setpoints with actual flow performance under varying backpressure conditions (up to 60 psi).
- Integrated safety interlock automatically cuts power to the motor when the pump head is opened—meeting IEC 61000-1-2 functional safety expectations for operator protection during tube servicing.
- Compact, stackable chassis (W × D × H: 185 × 220 × 245 mm) optimizes benchtop space in crowded analytical labs or modular cleanroom installations.
Sample Compatibility & Compliance
The FH100D/DX accommodates a wide range of peristaltic tubing materials—including PharMed® BPT, Norprene®, Viton®, and silicone—supporting compatibility with aqueous, organic, and mildly aggressive solvents. Tubing selection determines both flow rate range (from ~0.01 mL/min to >120 mL/min) and chemical resistance profile. The system complies with CE marking requirements under the Low Voltage Directive (2014/35/EU) and Electromagnetic Compatibility Directive (2014/30/EU). UL recognition confirms conformance with UL 61010-1 for laboratory equipment safety. All firmware and hardware design elements adhere to principles supporting GLP and GMP traceability, including audit-ready calibration history retention and secure parameter lockout options.
Software & Data Management
While the FH100D/DX operates as a standalone instrument with front-panel controls, it supports analog (0–10 VDC) and digital (RS-232) interfaces for integration into automated workflows. Optional Thermo Scientific LabConnect™ software enables remote configuration, batch log export (CSV), and synchronization with LIMS or MES platforms. All calibration data, dispense logs, and error events are timestamped and stored locally; firmware updates preserve historical calibration records. For regulated environments, the system supports 21 CFR Part 11–compliant electronic signatures when paired with validated host software and access-controlled user accounts.
Applications
- Automated sample preparation for HPLC, IC, and ICP-MS analysis—ensuring consistent dilution and standard addition.
- Cell culture bioreactor feed and harvest control in upstream processing.
- Pharmaceutical QC testing where USP and require documented dispensing repeatability.
- Environmental lab water analysis workflows involving acid digestion reagent delivery.
- Food & beverage quality assurance—precise metering of preservatives, enzymes, or flavorings in pilot-scale formulation trials.
FAQ
What tubing sizes are supported by the FH100D/DX?
Standard configurations accommodate tubing inner diameters from 0.13 mm to 3.2 mm (e.g., Cole-Parmer Masterflex L/S series), with flow ranges scalable accordingly.
Can the pump be integrated into a PLC-controlled production line?
Yes—via RS-232 serial communication or 0–10 V analog input/output, enabling start/stop, direction, speed, and status monitoring in industrial automation architectures.
Is firmware validation documentation available for GxP environments?
Thermo Scientific provides IQ/OQ protocol templates and firmware version release notes upon request for qualified customers engaged in validation projects.
How often does calibration need verification?
Per ISO/IEC 17025 guidance, calibration verification is recommended before each critical use or at defined intervals (e.g., daily or per shift), using gravimetric or volumetric reference standards.
Does the pump meet IP rating requirements for humid laboratory spaces?
The unit carries an IP20 rating; for splash-prone areas, optional enclosure kits with IP54-rated housings are available through authorized distributors.
