Overview
The DLAB DispensMate Manual Bottle Top Dispenser is an ergonomically engineered, chemically resistant liquid handling solution designed for precise, repeatable volumetric dispensing from reagent bottles in analytical, quality control, and research laboratories. Based on positive displacement piston mechanics, the DispensMate operates without reliance on gravity or bottle orientation—ensuring consistent delivery across viscosity ranges and container positions. Its modular architecture enables rapid interchange between four calibrated volume ranges, covering 0.5–50 mL in discrete, user-selectable increments. The device complies with ISO 8655-3 (2022) for piston-operated dispensers and meets functional requirements for routine use under GLP and GMP-aligned workflows where traceability and mechanical reproducibility are critical.
Key Features
- Chemically inert fluid path constructed from PTFE, FEP, borosilicate glass (BSG), and polypropylene (PP), ensuring compatibility with aggressive solvents, acids, bases, and organic media.
- Full autoclave compatibility: all wetted components withstand steam sterilization at 121°C for 20 minutes—validated per ISO 17665-1—supporting aseptic applications and cross-contamination prevention.
- Four interchangeable volume models (0.5–5 mL, 1–10 mL, 2.5–25 mL, 5–50 mL), each calibrated to ±0.2% accuracy and ≤0.5% coefficient of variation (CV), traceable to national standards.
- Tool-free disassembly design: piston assembly, valve block, and dispensing tip separate cleanly for visual inspection, ultrasonic cleaning, and replacement of wear-prone seals—reducing downtime and extending service life.
- Ergonomic handle geometry and low actuation force (<12 N) minimize operator fatigue during high-frequency dispensing tasks over extended shifts.
- Integrated volume lock mechanism prevents accidental setting changes during transport or storage.
Sample Compatibility & Compliance
The DispensMate accommodates standard laboratory reagent bottles with neck threads conforming to common international specifications—including S40 (DIN 13), GL25, GL28, GL32, and GL38. Each unit ships with five universal adapters, eliminating the need for custom fittings in multi-vendor lab environments. All materials comply with USP Class VI biological safety testing and EU Regulation (EC) No. 1935/2004 for food contact substances. The device supports compliance with FDA 21 CFR Part 11 when used in conjunction with validated electronic logbooks or LIMS-integrated documentation systems, as its mechanical operation generates no digital audit trail but permits manual entry of batch, lot, and calibration records.
Software & Data Management
As a fully manual, non-electronic instrument, the DispensMate does not incorporate embedded firmware, connectivity protocols, or onboard data logging. However, its calibration certificates—including serial-numbered reports with uncertainty values, test conditions, and reference standard traceability—are provided in English and digitally archivable. Laboratories implementing electronic recordkeeping may assign unique asset IDs and link calibration history to internal QA databases. For regulated environments, users are advised to maintain a physical calibration logbook with entries documenting date, operator, verification method (e.g., gravimetric check per ISO 8655-6), and pass/fail status—consistent with ISO/IEC 17025:2017 clause 7.7.
Applications
- Preparation of calibration standards and QC samples in environmental testing labs (e.g., EPA Method 502.2, ISO 11843).
- Accurate dispensing of hazardous or expensive reagents in pharmaceutical development, minimizing waste and exposure risk.
- Serial dilution workflows in microbiology and molecular biology, where sterility maintenance and inter-bottle consistency are essential.
- Formulation support in cosmetics and fine chemical manufacturing, particularly where batch-to-batch repeatability impacts stability testing outcomes.
- Teaching laboratories requiring robust, low-maintenance tools for student training in volumetric technique fundamentals per ASTM E2757.
FAQ
Is the DispensMate compatible with hydrofluoric acid (HF)?
Yes—when equipped with FEP and PTFE components only; avoid BSG (borosilicate glass) parts in HF applications. Consult the chemical resistance guide included in the user manual before exposure.
Can I recalibrate the DispensMate in-house?
Yes—gravimetric recalibration is supported using certified weights and Class A volumetric flasks per ISO 8655-6. DLAB provides a downloadable calibration protocol and uncertainty budget template.
Does the device meet ISO 8655 certification requirements?
Each model is factory-calibrated and certified to ISO 8655-3:2022 Annex A performance criteria. Full certification documentation is shipped with every unit.
What is the recommended maintenance interval?
Inspect seals and piston lubrication every 200 operating cycles or quarterly—whichever occurs first. Replace O-rings annually or after autoclaving >50 times.
Are replacement parts available globally?
Yes—DLAB maintains authorized distribution channels in North America, EMEA, and APAC. Critical spares (piston kits, valve assemblies, adapter sets) carry standardized part numbers and ship with CoA.
