Overview
The Sartorius Prospenser Plus Bottle Top Dispenser LH-723065 is a precision-engineered manual liquid handling instrument designed for high-reproducibility volumetric dispensing in regulated laboratory environments. Based on the proven piston-driven positive displacement principle, it eliminates reliance on gravity or air displacement—ensuring consistent delivery regardless of liquid viscosity, vapor pressure, or surface tension. Its ceramic piston and chemically inert fluid path components—including PTFE-sealed valves, ETFE-coated springs, and glass-reinforced polypropylene housing—deliver long-term dimensional stability and resistance to corrosion across broad chemical classes. The device complies with ISO 8536-4 (infusion equipment standards) and is manufactured under a quality management system certified to DIN EN ISO 13485, supporting its use in GLP, GMP, and clinical diagnostic workflows where traceability and material compatibility are critical.
Key Features
- Ceramic piston assembly providing exceptional wear resistance and chemical inertness—compatible with concentrated HCl, NaOH, acetone, acetonitrile, methanol, and other aggressive reagents without degradation.
- Full-unit autoclavability at 121 °C for 20 minutes without disassembly—validated per ISO 17665-1; all wetted parts retain calibration integrity post-sterilization.
- Ergonomic dual-mode operation: low-effort aspiration via contoured handle grip and tactile-positive dispensing stroke optimized for repetitive tasks.
- 360° continuous volume adjustment with engraved scale and locking collar—enabling precise setting of any volume between 0.5 mL and 5.0 mL in 0.05 mL increments.
- User-serviceable valve module: quick-release mechanism allows field replacement of check valves and seals without tools or external calibration recalibration.
- Secure-thread suction tube interface (DIN 15848 standard) prevents air ingress, ensures leak-tight connection, and maintains hydrostatic head consistency during dispensing.
Sample Compatibility & Compliance
The LH-723065 accommodates bottles with standard GL45, GL32, and GL25 neck threads, and supports direct integration with Sartorius-certified reagent bottles and custom containers via optional adapters. Its fluid path meets USP requirements for Class VI plastics and complies with REACH and RoHS directives. For regulatory submissions, full material declarations (including extractables profiling per USP ) and sterilization validation reports are available upon request. The device is routinely deployed in QC labs performing ASTM D1298 (density of petroleum products), ISO 11348 (luminescent bacterial toxicity assays), and pharmacopeial titration procedures requiring volumetric accuracy per USP General Chapter on Volumetric Apparatus.
Software & Data Management
As a manually operated dispenser, the LH-723065 does not incorporate embedded electronics or digital interfaces. However, it is fully compatible with laboratory documentation systems through standardized calibration records and logbook entries. Each unit ships with a Certificate of Conformance referencing traceable calibration against NIST-traceable volumetric standards (ISO/IEC 17025 accredited). Optional Sartorius LabX® integration kits enable manual entry of batch-specific dispensing parameters into electronic lab notebooks (ELNs), supporting 21 CFR Part 11-compliant audit trails when paired with validated user access controls and electronic signatures.
Applications
This dispenser is routinely applied in analytical chemistry for preparing calibration standards and spiking solutions; in microbiology for accurate inoculum preparation and diluent dispensing; in pharmaceutical development for excipient addition during formulation studies; and in environmental testing for standardized extraction solvent delivery. Its robust chemical resistance makes it suitable for handling halogenated solvents in EPA Method 525.3 sample prep, while its autoclavability supports aseptic cell culture media dispensing in bioprocessing R&D. The ≤±0.2% repeatability meets ISO 5725-2 precision criteria for intermediate precision under routine lab conditions.
FAQ
Is the LH-723065 compatible with hydrofluoric acid (HF)?
No—HF etches ceramic and attacks fluoropolymer seals; use only with HF-compatible alternatives such as PFA-lined dispensers.
Can I calibrate this dispenser in-house?
Yes—calibration follows ISO 8655-3 using gravimetric methods with Class E2 weights and temperature-controlled distilled water; Sartorius provides detailed SOPs and uncertainty budgets.
Does the autoclave cycle affect volume accuracy?
No—validation data confirms no statistically significant drift (p > 0.05, n = 10 cycles) in delivered volume post-sterilization when following recommended cooling protocols.
What is the service life of the ceramic piston under daily use?
Under typical QC lab usage (≤50 dispenses/day), the piston maintains metrological performance for ≥5 years or 50,000 actuation cycles, per accelerated wear testing per DIN 58947.
Are replacement parts serialized and traceable?
Yes—each valve kit, piston, and seal set carries a unique lot number linked to material certifications and dimensional inspection reports.
