Efficient, safe, and precise fluid removal is critical for laboratories focused on cell culture, molecular biology, diagnostics, and automated workflows. ARES Scientific offers a wide selection of benchtop aspiration systemsโalso known as vacuum aspiration systems, lab vacuum aspirators, and fluid waste aspiration stationsโdesigned to streamline liquid aspiration, supernatant removal, media exchanges, wash steps, and waste capture while protecting samples, users, and equipment.
Our aspiration system portfolio includes units with adjustable vacuum control, quiet or oil-free pumps, autoclavable components, hydrophobic/bacterial filters, and ergonomic handpieces suitable for both biosafety cabinets and open benches. Whether you are aspirating from microplates, multi-well plates, centrifuge tubes, conical tubes, flasks, culture dishes, or reservoirs, the right system improves throughput, reduces contamination risk, and integrates smoothly with your liquid-handling and sample-preparation processes.
Aspiration systems are essential in workflows such as cell culture media changes, wash steps in ELISA and immunoassays (coordinate with microplate washers for automated plate processing), DNA/RNA extraction supernatant removal (following centrifugation), protein purification, and biosafety-level waste disposal. They are particularly important for live-cell cultures maintained in COโ incubators. During routine media changes, wash steps, and feeding cycles, aspirators remove spent media and wash buffers without disturbing attached cell layers, helping maintain culture viability and reducing contamination risk. Proper pairing of a benchtop vacuum aspirator with a COโ incubator environment ensures consistent handling of sensitive iPSC, primary, and adherent cell lines.
At ARES Scientific, we help you compare key criteria such as vacuum range, flow rate, collection bottle size, filtration type, system footprint, noise level, and compatibility with biosafety cabinets, laminar-flow hoods, or clean-bench environments. Support for cell culture labs, high-throughput screening facilities, molecular diagnostics labs, microbiology and immunology labs, and general research media handling ensures that our aspiration systems deliver reliability, ease of use, ergonomic operation, and biosafety-focused performance.
A benchtop aspiration system is a compact, self-contained vacuum-based fluid removal system designed to quickly and safely remove liquidsโsuch as supernatant, wash solutions, and spent mediaโfrom laboratory vessels. These systems combine a controlled vacuum source, waste collection bottle, filters, and ergonomic handpieces for convenient use on the bench or inside a biosafety cabinet.
Manual pipetting is slow, ergonomically demanding, and increases the risk of spills or inconsistent liquid removal. A vacuum aspiration system standardizes fluid removal, improves throughput, reduces repetitive strain, minimizes aerosol formation, and helps maintain clean, reproducible workflowsโespecially in high-volume cell culture or assay labs.
Yes. Many aspiration systems are specifically designed to operate inside biosafety cabinets and laminar-flow hoods, featuring compact footprints, quiet pumps, autoclavable parts, and hydrophobic filters that block aerosols. This makes them ideal for microbiology, virology, and tissue-culture workflows that involve biohazardous liquid waste.
Live-cell culture requires frequent media changes, wash steps, and feeding cycles. Aspiration systems remove old media and wash solutions gently, helping prevent detachment of adherent cells and preserving monolayers. Their controlled vacuum, sterile filters, and autoclavable components support sterile technique during transfers between the COโ incubator, biosafety cabinet, and bench.
Consider the vessels you use most (microplates, flasks, culture dishes, tubes), the total daily volume of liquid waste, your biosafety level, and workspace layout. For small-scale or microplate-focused work, a compact portable aspirator may be sufficient. For high-throughput or multi-user labs, choose a system with higher flow rates, larger waste bottles, robust filtration, and multi-channel accessories that can keep up with intensive cell culture and assay workloads.
Most aspiration systems use hydrophobic aerosol-blocking filters (0.2โ0.45 ยตm) that prevent contamination, protect the pump, and reduce aerosol exposure. Labs operating under BSL-2 or BSL-3 conditions require validated, replaceable filters for safe waste handling. Coordinate aspiration system filtration with environmental monitoring programs verifying contamination control effectiveness.
Some aspiration systems are compatible with mild chemical or buffer waste, but corrosive solvents require chemical-resistant vacuum systems. Always check compatibility of tubing, bottle materials, and filters before aspirating solvent-containing waste. For specialized chemical handling, explore ductless fume hoods with integrated aspiration capabilities.
Waste bottles should be capped, autoclaved if biohazardous (coordinate with autoclaves or decontamination systems), and disposed of according to institutional biosafety or chemical-waste procedures. Autoclavable bottles and quick-release lids simplify safe disposal and decontamination.
High-throughput labs processing plates or multiple samples benefit from aspirators with higher flow rates, large waste bottles, multi-channel aspiration heads, and compatibility with automation platforms or robotic liquid handlers coordinating with microplate readers, microplate washers, and liquid handling workstations.
Yes. Filters, tubing, and waste bottles require periodic replacement or sterilization. Pumps should be checked regularly for performance, cleaned as needed, and maintained according to manufacturer recommendationsโespecially in biosafety environments where contamination control is critical.
