Harvard Apparatus Pump 11 Elite Glucose Clamp Syringe Pump

Overview

The Harvard Apparatus Pump 11 Elite Glucose Clamp Syringe Pump is a precision-engineered, programmable infusion system specifically designed for dynamic, bidirectional glucose clamp studies in preclinical metabolic research. Built upon the proven Pump 11 platform and developed in collaboration with endocrinology and diabetes research laboratories, this pump implements real-time, closed-loop control algorithms that enable simultaneous infusion and withdrawal of glucose and insulin solutions—critical for maintaining euglycemia during hyperinsulinemic-euglycemic clamp procedures. Its operation relies on high-resolution microstepping motor control and calibrated syringe detection, ensuring volumetric accuracy traceable to NIST standards. The system supports both single- and dual-syringe configurations, allowing flexible experimental design while maintaining strict compliance with GLP-aligned data integrity requirements.

Key Features

• Bidirectional programmability: Full injection-and-withdrawal capability per syringe channel, essential for glucose clamp protocols requiring real-time feedback-driven titration.
• High-precision dosing: ±0.5% volumetric accuracy and ±0.05% repeatability across the full operating range—from picoliter-scale infusions (1.26 pL/min) to milliliter-per-minute delivery (up to 88.4 mL/min).
• Intelligent syringe recognition: Automatic detection and calibration for plastic or glass syringes (0.5 µL–60 mL capacity), minimizing setup error and operator dependency.
• Integrated glucose clamp mode: Preloaded firmware algorithm enabling automated glucose infusion rate (GIR) calculation and adjustment based on continuous blood glucose monitoring inputs (compatible with external glucometers via TTL-triggered I/O).
• Robust mechanical architecture: 16 kg maximum linear force ensures reliable operation with high-viscosity solutions and extended-duration clamps (>6 hours) without stalling or positional drift.
• Human-centered interface: 4.3″ WQVGA color touchscreen with intuitive graphical workflow navigation, multi-language support, and on-device protocol storage (up to 100 user-defined methods).

Sample Compatibility & Compliance

The Pump 11 Elite Glucose Clamp Syringe Pump accommodates standard Luer-lock syringes made of borosilicate glass or medical-grade polypropylene, supporting volumes from 0.5 µL (e.g., Hamilton 1001TLL) up to 60 mL (e.g., BD Plastipak). It is validated for use with aqueous glucose solutions (5–50% w/v), human/animal insulin formulations (U-100 to U-1000), and saline-based vehicle controls. All firmware and hardware components meet CE marking requirements under Directive 2014/30/EU (EMC) and 2014/35/EU (LVD). For regulated environments, the pump supports audit-trail-enabled operation when integrated with compliant data acquisition systems adhering to FDA 21 CFR Part 11 and ISO/IEC 17025 guidelines.

Software & Data Management

Control and method development are supported via Harvard Apparatus’ proprietary Pump Control Software (v5.2+), compatible with Windows 10/11 (64-bit). The software enables synchronized multi-pump coordination, time-stamped event logging, and export of CSV-formatted infusion logs with metadata (timestamp, volume delivered/withdrawn, flow rate, syringe ID, error codes). Raw data streams can be routed via RS485 or USB to third-party platforms including LabChart, MATLAB, or Python-based acquisition suites using provided SDKs (C/C++, .NET, Python APIs). All configuration changes and run records are timestamped and user-logged—enabling full traceability for internal QA reviews or regulatory submissions.

Applications

• Hyperinsulinemic-euglycemic clamp studies in rodents, non-human primates, and large animal models.
• Insulin sensitivity quantification (M-value derivation) and hepatic glucose production assessment.
• Pharmacodynamic evaluation of novel antidiabetic compounds (GLP-1 analogs, SGLT2 inhibitors, dual agonists).
• Metabolic phenotyping in genetically modified mouse strains (e.g., ob/ob, db/db, liver-specific knockouts).
• Integration into automated metabolic cages or IVIS-compatible surgical setups requiring TTL-synchronized bolus triggers.

FAQ

Does the Pump 11 Elite Glucose Clamp model support dual-syringe independent control?
Yes—models 70-4505GC and 70-4506GC provide fully independent, synchronized control of two syringes, enabling concurrent glucose infusion and insulin withdrawal within a single clamp session.
Can the pump interface with continuous glucose monitoring (CGM) systems?
It does not natively integrate CGM hardware but accepts TTL-level trigger signals from external glucometers or analog-to-digital converters, allowing external glucose values to modulate infusion rates via custom scripts or third-party control software.
Is firmware update capability available in the field?
Yes—firmware updates are distributed via Harvard Apparatus’ secure customer portal and installed through USB or RS485 connection; version history and release notes comply with IEC 62304 Class B software lifecycle requirements.
What documentation is supplied for regulatory validation?
Each unit ships with a Factory Calibration Certificate (traceable to NIST), IQ/OQ protocol templates, and a Device Master Record summary aligned with ISO 13485:2016 and FDA QSR 21 CFR Part 820.
