ROCKER L100-Basic Vacuum Liquid Aspiration Pump

Overview

The ROCKER L100-Basic Vacuum Liquid Aspiration Pump is an engineered solution for precise, contamination-controlled liquid handling in bioscience and cell culture laboratories. Designed around a brushless DC motor and integrated vacuum generation system, it operates on the principle of controlled negative pressure to enable rapid, consistent aspiration of supernatants, culture media, and buffer solutions—without compromising sterility or workflow integrity. Its compact footprint (265 × 130 × 210 mm) allows direct placement inside laminar flow hoods or biosafety cabinets, eliminating the need for external vacuum lines or centralized systems. Unlike conventional vacuum pumps requiring oil lubrication or complex plumbing, the L100-Basic delivers maintenance-free, quiet operation with a maximum flow rate of 1000 mL/min and an ultimate vacuum level of 347 mbar (equivalent to ~500 mmHg), sufficient for routine filtration and aspiration tasks across tissue culture, molecular biology, and quality control applications.

Key Features

• Compact, benchtop-integrated design optimized for Class II biosafety cabinets and laminar airflow workstations
• Dual-function capability: simultaneous support for vacuum-assisted liquid aspiration (e.g., spent media from Petri dishes or microplates) and vacuum-driven filtration (e.g., sterile clarification of growth media or buffers)
• Autoclavable accessories—including POM pipette tip holders, PP bottle caps, and optional stainless-steel tip ejectors—validated for steam sterilization at 121°C for 20 minutes under ISO 17665-1 conditions
• Ergonomic one-handed tip ejection mechanism with tactile Lock key to prevent accidental activation during sensitive procedures
• Brushless DC motor ensures long service life, low electromagnetic interference (EMI), and stable performance across variable load conditions
• Universal AC input (100–240 V, 50/60 Hz) with regulated DC 12 V output for consistent motor torque and thermal stability

Sample Compatibility & Compliance

The L100-Basic is compatible with standard laboratory consumables including 500 mL GL45 glass filtration bottles, 25 mm disc filters (0.2 µm pore size), and both reusable PES filtration funnels (LF3a/LF5a) and disposable Autofil units (15 mL, 50 mL, and 500 mL formats). All wetted components comply with USP Class VI biocompatibility requirements. The system meets CE marking directives for electrical safety (2014/35/EU) and electromagnetic compatibility (2014/30/EU). While not intrinsically rated for hazardous environments, its sealed motor housing and absence of oil or volatile lubricants make it suitable for ISO 5 (Class 100) cleanroom operations when used with appropriate PPE and procedural controls per ISO 14644-1.

Software & Data Management

The L100-Basic is a standalone, hardware-only instrument with no embedded firmware, touchscreen interface, or digital connectivity. It does not generate electronic records, nor does it support audit trails, user authentication, or data export—making it inherently compliant with environments where regulatory simplicity is prioritized over digital traceability. For laboratories operating under GLP or GMP frameworks requiring documented operational parameters, external process logs (e.g., manual timestamps, operator initials, and batch-specific usage records) are recommended. Its mechanical reliability and lack of software dependencies reduce validation burden during FDA 21 CFR Part 11 assessments where electronic records are not mandated.

Applications

• Aspiration of supernatant from adherent or suspension cell cultures in T-flasks, multiwell plates, and Petri dishes
• Vacuum-assisted sterile filtration of serum-containing media, PBS, HEPES buffers, and enzyme solutions using 0.2 µm or 0.22 µm PES membranes
• Clarification of lysates or conditioned media prior to centrifugation or chromatography steps
• Routine removal of wash buffers during ELISA, immunostaining, or Western blotting workflows
• Integration with centrifuge tube filtration adapters for scalable sample processing (e.g., 15 mL or 50 mL conical tubes)
• Support of aseptic technique in stem cell labs, hybridoma facilities, and vaccine development suites where cross-contamination risk must be minimized

FAQ

Can the L100-Basic be used inside a CO₂ incubator?
No—the unit is designed for ambient temperature operation only and lacks environmental sealing for humid, elevated-CO₂ atmospheres.
Is the main pump housing autoclavable?
No—only accessories (bottle caps, tip holders, stainless-steel ejectors) are rated for autoclaving; the ABS housing and motor assembly must not be exposed to steam or high humidity.
What is the expected service life of the brushless DC motor?
Under typical laboratory use (≤4 hrs/day, intermittent duty cycle), the motor demonstrates ≥20,000 hours of operational endurance per IEC 60034-18-41 accelerated life testing protocols.
Does the system include a vacuum regulator or pressure gauge?
No—the L100-Basic operates at fixed vacuum output; users requiring adjustable vacuum levels should consider the ROCKER L100-Pro or L200 series models.
Are replacement filters and bottles available through global distribution channels?
Yes—GL45 glass bottles, 25 mm disc filters (0.2 µm), and Autofil disposable units are stocked by authorized ROCKER distributors in North America, EMEA, and APAC regions under catalog numbers 197000-60, 197100-43, and 1152-RLS respectively.
