Overview
The ZiQi DVP-10 Portable Diaphragm Vacuum Pump is an oil-free, compact vacuum source engineered for precision and reliability in routine laboratory applications requiring low-to-moderate vacuum levels. Based on positive displacement via a PTFE-coated elastomeric diaphragm and dual-valve architecture, the DVP-10 generates vacuum through mechanical oscillation—eliminating lubricants, minimizing maintenance, and ensuring contamination-free operation essential for analytical sample preparation. With an ultimate vacuum of 200 mbar (abs) and a nominal air displacement rate of 10 L/min at atmospheric pressure, the pump delivers stable suction performance suitable for intermittent duty cycles in controlled environments. Its lightweight (3.2 kg), ergonomic hand-carry form factor and minimal footprint (250 × 65 × 190 mm) make it ideal for benchtop mobility across multi-station labs, field-deployable QA/QC units, or teaching laboratories where space and portability are critical constraints.
Key Features
- Oil-free diaphragm design ensures zero hydrocarbon contamination—critical for solvent-sensitive applications such as HPLC sample prep or GC vial evacuation.
- PTFE-reinforced diaphragm and chemically resistant valve materials provide extended service life under non-corrosive load conditions.
- Thermally protected 80 W induction motor enables consistent torque delivery while limiting thermal drift during short-duration operation.
- Integrated vibration-damping feet and low-noise (<55 dB[A]) operation support use in shared lab spaces without acoustic interference.
- Single-port inlet configuration with standard 6 mm OD barbed fitting simplifies connection to filtration manifolds, SPE cartridges, or rotary evaporator traps.
- Designed for intermittent duty: rated for ≤30 minutes continuous operation per cycle, aligning with ISO 8573-1 purity class 0 compatibility for non-oiled compressed air systems.
Sample Compatibility & Compliance
The DVP-10 is validated for use with aqueous, polar organic, and halogenated solvents commonly employed in solid-phase extraction (SPE), gravity-assisted membrane filtration, and low-temperature vacuum concentration. It is explicitly not rated for use with oxidizing agents (e.g., chlorine, nitric oxide), flammable vapors above LEL thresholds, or strongly acidic/basic gases (e.g., HCl, NH₃). As a Class II laboratory auxiliary device, it complies with IEC 61010-1:2010 for electrical safety and meets CE marking requirements for electromagnetic compatibility (EMC Directive 2014/30/EU). While not certified for GMP or GLP environments out-of-the-box, its mechanical simplicity and absence of consumable oils facilitate audit-ready documentation when integrated into SOP-controlled workflows.
Software & Data Management
The DVP-10 operates as a standalone analog device with no embedded microcontroller, firmware, or digital interface. This architecture eliminates cybersecurity risks, software validation overhead, and firmware update dependencies—making it suitable for regulated environments where deterministic behavior and traceable manual operation are prioritized over automation. Vacuum level monitoring requires external instrumentation (e.g., analog vacuum gauge, digital pressure transducer), and all operational logs—including runtime duration, maintenance intervals, and buffer bottle inspection records—must be maintained manually per institutional GLP or ISO/IEC 17025 documentation protocols.
Applications
- Solvent-based membrane filtration of biological samples, environmental water extracts, or pharmaceutical suspensions.
- Conditioning and elution steps in solid-phase extraction workflows for pesticide residue analysis or clinical biomarker isolation.
- Support vacuum for cold trap condensation in rotary evaporation setups operating below 40 °C.
- Evacuation of desiccators and vacuum ovens used in gravimetric moisture determination (ASTM D1557, ISO 1189).
- Pre-vacuum priming of liquid handling systems prior to automated pipetting or dilution sequences.
FAQ
Can the DVP-10 be operated continuously for more than 30 minutes?
No. Thermal accumulation exceeds safe limits beyond 30 minutes of uninterrupted operation. Allow ≥15 minutes cooldown between cycles.
Is a vacuum gauge included with the pump?
No. The DVP-10 does not include an integrated pressure indicator. Users must supply a compatible analog or digital vacuum gauge calibrated to the 10–1000 mbar range.
What type of tubing is recommended for inlet connections?
Chemically inert, vacuum-rated tubing with minimum burst pressure ≥3× operating vacuum differential—e.g., reinforced silicone or fluoropolymer-lined PVC (ID 6 mm, wall thickness ≥1.5 mm).
Does the pump require periodic oil changes or filter replacements?
No. As an oil-free diaphragm pump, it has no lubrication system. However, inlet particulate filters (optional accessory) should be inspected before each use and replaced if clogged.
Can the DVP-10 be used in explosion-proof environments?
No. It lacks ATEX or IECEx certification and contains non-intrinsically safe electrical components. Use only in general-purpose laboratory areas compliant with NFPA 45 ventilation standards.
