DLAB SmartVac 1L Benchtop Vacuum Aspirator

Overview

The DLAB SmartVac 1L Benchtop Vacuum Aspirator is an engineered solution for precise, contamination-controlled liquid aspiration in regulated laboratory environments. Operating on the principle of controlled negative pressure generation via a brushless DC motor-driven vacuum pump, the SmartVac delivers consistent aspiration performance without reliance on central vacuum systems or compressed air infrastructure. Its fixed vacuum output of 600 mbar (≈450 Torr) is optimized for safe handling of aqueous, buffered, and low-viscosity biological solutions—ensuring reliable removal of supernatants, culture media, wash buffers, and reagent residues without cell shearing or aerosol generation. Designed for ISO 13485-aligned workflows and GLP-compliant sample preparation, the device supports traceable, repeatable liquid handling across academic research labs, QC/QA facilities, and GMP-manufacturing support zones.

Key Features

• Compact benchtop footprint (127 × 144 × 244 mm) minimizes spatial demand while maintaining full aspiration functionality—ideal for biosafety cabinets, laminar flow hoods, and mobile lab carts.
• Integrated rechargeable lithium-ion battery enables up to 12 hours of continuous operation per charge, eliminating cord constraints during multi-step protocols or field-deployed applications.
• Hydrophobic PTFE membrane filter (0.2 µm pore size) installed upstream of the pump prevents aerosol ingress and liquid backflow, safeguarding both internal components and operator safety per ISO 15195 and CLSI EP25-A guidelines.
• All fluid-path components—including collection bottle, tubing connectors, and suction nozzle—are constructed from autoclavable polypropylene and medical-grade silicone, validated for repeated sterilization at 121°C, 2 bar for 20 minutes (EN 285 compliant).
• Single-button activation with tactile feedback ensures intuitive operation; no software setup or calibration required prior to use.
• Low-noise operation at ≤53 dB(A) meets WHO occupational exposure thresholds for continuous use in shared laboratory spaces.

Sample Compatibility & Compliance

The SmartVac accommodates standard 1 L borosilicate glass or autoclavable PP collection bottles (optional 500 mL and filter flask configurations available), compatible with common sterile filtration setups (e.g., 0.45 µm or 0.22 µm membrane filters). It is routinely deployed in workflows requiring adherence to USP , , and ISO 14644-1 Class 5–7 environments. All wetted materials comply with USP Class VI biocompatibility testing and EU Regulation (EC) No 1935/2004 for food-contact safety. Device documentation includes Declaration of Conformity to CE (2014/30/EU EMC Directive and 2014/35/EU Low Voltage Directive) and RoHS 2011/65/EU compliance.

Software & Data Management

As a stand-alone, non-networked instrument, the SmartVac does not incorporate embedded firmware, touchscreen interface, or data logging capabilities. Its design follows IEC 61010-1:2010 safety architecture for laboratory electrical equipment, prioritizing mechanical reliability over digital integration. For laboratories implementing 21 CFR Part 11-compliant electronic records, usage logs may be maintained externally via lab notebook entries or LIMS-integrated task tracking—consistent with FDA guidance on “simple devices without audit trail functionality.”

Applications

• Cell culture maintenance: rapid aspiration of spent media from T-flasks, multiwell plates, and roller bottles without cross-contamination risk.
• Molecular biology workflows: removal of ethanol washes post-DNA precipitation, buffer exchange in column-based purification, and gel electrophoresis tray cleaning.
• Clinical diagnostics: processing of urine, serum, and CSF samples prior to centrifugation or automated analyzer input.
• Pharmaceutical manufacturing: in-process sampling line clearance, filter integrity test effluent collection, and environmental monitoring swab fluid recovery.
• Food microbiology: membrane filtration of water or rinse samples followed by direct colony transfer to agar surfaces.

FAQ

Is the SmartVac compatible with vacuum manifolds or multi-well plate adapters?
Yes—standard Luer-lock and 8-mm barbed fittings allow seamless integration with commercially available manifold systems and 96-well aspiration heads.
Can the collection bottle be used under positive pressure or as a pressurized filtration vessel?
No—the SmartVac is designed exclusively for vacuum aspiration; it lacks pressure-rated seals or burst protection for pressurized operation.
What is the recommended maintenance interval for the hydrophobic filter?
Replace the 0.2 µm PTFE filter after every 50 hours of cumulative use or immediately following aspiration of viscous or protein-rich fluids.
Does the device support continuous duty cycle operation?
Yes—rated for uninterrupted operation up to 12 hours on a full battery charge, with thermal cutoff protection activated above 65°C internal temperature.
Are spare parts such as tubing, nozzles, and batteries available through DLAB’s global distribution network?
Yes—original equipment manufacturer (OEM) replacement kits (P/N SV-ACC-KIT) include autoclavable nozzles, silicone tubing, and certified Li-ion battery modules with CE-marked chargers.
