Overview
The Sartorius Prospenser LH-723064 is a high-precision manual bottle top dispenser engineered for reproducible, safe, and contamination-free liquid handling in analytical, quality control, and research laboratories. Based on positive displacement piston technology, it delivers consistent volumetric delivery across its full range of 0.2–2.0 mL without reliance on gravity or liquid density—ensuring reliable performance with viscous, volatile, or low-surface-tension fluids including concentrated acids (e.g., HNO₃, HCl), caustic bases (e.g., NaOH), and organic solvents (e.g., acetone, chloroform). Its all-glass syringe barrel, PTFE-coated piston, and chemically inert polypropylene housing provide long-term stability and resistance to aggressive reagents. Designed for direct mounting onto standard GL45, GL32, and GL25 threaded reagent bottles, the LH-723064 eliminates intermediate transfer steps—reducing exposure risk, evaporation loss, and cross-contamination.
Key Features
- Full autoclavability: Entire unit withstands sterilization at 121 °C, 2 bar for 20 minutes—validated for use in GLP/GMP environments requiring routine decontamination.
- Tool-free disassembly: Glass syringe barrel detaches from base for thorough cleaning and visual inspection; no hidden crevices or trapped residues.
- Two-stage precision adjustment: Coarse volume setting via rotary dial + fine-tuning knob enables sub-microliter resolution (0.02 mL increments) and repeatability ≤ ±0.2% RSD.
- Integrated anti-drip safety valve: Automatically seals fluid path upon release of dispensing lever—preventing post-dispense drips and ensuring operator safety during hazardous liquid handling.
- Chemically resistant fluid path: Borosilicate glass barrel, PTFE piston seal, and PP body resist corrosion from strong oxidizers, halogenated solvents, and alkaline solutions per DIN ISO 17025 compatibility guidelines.
- Universal bottle interface: Adjustable collar accommodates GL25, GL32, and GL45 neck threads; optional adapters available for non-standard containers.
- ISO 8655-3 compliant calibration: Built-in two-point user calibration protocol aligns with international standards for piston-type dispensers—traceable documentation supports audit readiness.
Sample Compatibility & Compliance
The LH-723064 is validated for use with aqueous, organic, and corrosive liquids commonly encountered in pharmaceutical QC (e.g., USP analytical instrument qualification), environmental testing (EPA Method 3500 series), and academic synthesis labs. Its materials comply with EU Regulation EC No. 1935/2004 for food-contact safety and USP Class VI biocompatibility requirements. All dispensing components meet ISO 8655-3 mechanical accuracy specifications and are compatible with laboratory quality management systems adhering to ISO/IEC 17025, FDA 21 CFR Part 11 (when paired with Sartorius LabX software), and GMP Annex 11 data integrity expectations.
Software & Data Management
While the LH-723064 operates as a standalone mechanical device, its calibration records and usage logs integrate seamlessly into Sartorius LabX Liquid Handling software (optional). LabX provides electronic calibration workflows, digital signature capture, automatic report generation (PDF/CSV), and secure audit trails meeting ALCOA+ principles. All calibration events—including date, operator ID, reference standard used, and deviation values—are timestamped and stored with role-based access control, supporting regulatory inspections under FDA, EMA, or PMDA frameworks.
Applications
- Preparation of calibration standards and reference solutions in ICP-MS, HPLC, and titration workflows.
- Accurate dosing of hazardous reagents (e.g., HF, bromine, pyridine) in synthetic chemistry labs.
- QC testing of raw materials and finished products per pharmacopoeial monographs (USP, EP, JP).
- Environmental sample dilution prior to GC-MS or IC analysis per ISO 17294-2 protocols.
- Cell culture media preparation where sterility and batch-to-batch consistency are critical.
- Teaching laboratories requiring robust, serviceable equipment aligned with ISO/IEC 17025 pedagogical standards.
FAQ
Can the LH-723064 be calibrated by the end user?
Yes—using the integrated dual-point calibration procedure outlined in the operator manual, users can verify and adjust volume delivery against certified traceable standards without external tools.
Is the glass syringe barrel replaceable?
Yes—the borosilicate glass barrel is a field-replaceable component (Sartorius P/N 723064-001); replacement maintains metrological equivalence and does not require recalibration.
Does it support integration with LIMS or ELN systems?
When used with LabX software, dispensing events, calibration data, and maintenance logs export directly to LIMS/ELN via ODBC or REST API—enabling full digital workflow traceability.
What is the recommended maintenance interval?
Visual inspection before each use; full disassembly and cleaning after every 500 dispenses or when handling viscous/suspended samples; annual verification against ISO 8655-3 tolerances is advised for regulated environments.
Are spare parts and service documentation available globally?
All consumables, seals, and technical manuals are distributed through Sartorius’ authorized service network across >120 countries—with multilingual support and certified technician dispatch available within 72 hours in major markets.
