ROCKER Vacuum Pumps Series – Oil-Free & Corrosion-Resistant Laboratory Vacuum Systems

Overview

ROCKER vacuum pumps are engineered for precision, reliability, and chemical compatibility in demanding laboratory environments. Designed and manufactured in Taiwan, the ROCKER series encompasses a comprehensive portfolio of oil-free piston vacuum pumps, corrosion-resistant PTFE-coated diaphragm pumps, chemically inert Chemker models, rotary vane oil-lubricated pumps (Tanker series), and integrated vacuum filtration systems. These instruments operate on fundamental principles of positive displacement—either via reciprocating pistons or oscillating diaphragms—to generate stable vacuum levels without oil contamination, ensuring compliance with ISO 8573-1 Class 0 air purity requirements for critical applications such as solvent filtration, lyophilization support, vacuum drying, and sterile filtration. All ROCKER vacuum systems meet IEC 61000-6-3 (EMC) and IEC 61000-6-2 (immunity) standards, and select models—including Chemker and Rocker8xx series—are certified to UL/CSA 61010-1 for laboratory safety.

Key Features

• Oil-free operation across piston and diaphragm platforms eliminates risk of hydrocarbon contamination, supporting GLP/GMP workflows requiring trace-level purity.
• Corrosion-resistant construction: Chemker series feature PTFE-coated wetted parts and stainless-steel housings; Rocker-C variants integrate PTFE-coated membranes for enhanced resistance to organic solvents and mild acids.
• Wide vacuum range: From coarse vacuum (99 mbar) for rapid liquid aspiration to high vacuum (7 mbar absolute) for sensitive membrane filtration and concentration protocols.
• Modular system integration: Compatible with ROCKER’s full ecosystem—including MultiVac multi-port filter manifolds, VF/LF/SF vacuum filtration kits, BioDolphin bio-waste aspirators, and SolarVac rotating multi-position filter bases.
• Intelligent control options: Pilot100 and DC Chem 610 Pro vacuum controllers enable programmable setpoints, real-time pressure monitoring, and automatic pump cycling to extend service life and improve process repeatability.
• Low-noise, low-vibration architecture: Optimized motor mounts and balanced piston assemblies reduce operational noise to ≤52 dB(A), suitable for shared lab spaces and laminar flow hoods.

Sample Compatibility & Compliance

ROCKER vacuum systems accommodate diverse sample types—from aqueous buffers and ethanol-based washes to aggressive solvents including acetone, chloroform, and 10% HCl (with Chemker410/610 models). All wetted materials comply with USP Class VI biocompatibility testing. The Chemker line meets ASTM D471 for elastomer resistance, while stainless-steel components (e.g., MultiVac300-MB, SolarVac601-MB) are passivated per ASTM A967 and rated for autoclaving at 121°C/20 psi for ≥1,000 cycles. Vacuum filtration assemblies—including LF30, MF3, and VF-series bottles—support regulatory documentation per FDA 21 CFR Part 11 when paired with validated software (e.g., Galaxy331 data export). CE marking, RoHS compliance, and Taiwan Bureau of Standards, Metrology and Inspection (BSMI) certification are standard across all active models.

Software & Data Management

While most ROCKER vacuum pumps operate as standalone hardware, integrated digital functionality is available through companion devices. The Galaxy331 colony counter includes proprietary PC software for statistical analysis (mean CFU, SD, CV%), USB data export (CSV/TXT), and audit-trail-enabled session logging—fully compliant with ALCOA+ data integrity principles. Pilot100 vacuum controllers log timestamped pressure events and cycle history, exportable via RS-232 or USB for inclusion in electronic lab notebooks (ELN). For fully automated workflows, ROCKER systems interface with third-party LIMS platforms using Modbus RTU protocol. No cloud connectivity or proprietary SaaS platforms are embedded—ensuring full data sovereignty and alignment with institutional IT security policies.

Applications

ROCKER vacuum solutions serve core workflows across pharmaceutical QC, academic research, environmental testing, and clinical diagnostics. Piston pumps (Rocker300–911) support routine vacuum filtration of microbiological media, protein precipitation, and HPLC mobile phase degassing. Chemker models enable acid digestion sample prep and corrosive gas handling in ICP-MS labs. BioDolphin aspirators (Lafil200–400, BioVac225–240) fulfill CLSI GP35-A4 biosafety requirements for biological waste removal under BSL-2 conditions. MultiVac and SolarVac manifolds facilitate high-throughput sterility testing per USP , while WELVAC210 enables parallel processing of 96-well microplates and spin columns per ISO 15189 Annex C. Tanfil 100 tangential flow filtration systems support buffer exchange and concentration of monoclonal antibodies at bench scale under cGMP-aligned operating procedures.

FAQ

What vacuum level is required for sterile filtration using 0.22 µm PVDF membranes?
For reliable throughput and membrane integrity, a minimum vacuum of 25–40 mbar absolute is recommended—achievable by Rocker410, Rocker910, or Chemker410 models.
Can Rocker8xx series pumps be used for vacuum oven applications?
Yes—the Rocker800/810 series deliver stable -670 to -735 mmHg (≈90–98 kPa vacuum) and are rated for continuous duty at ambient temperatures up to 40°C, making them suitable for desiccation and low-temperature drying.
Are Chemker pumps compatible with aggressive solvents like THF or DMF?
Chemker410/610 models—with PTFE diaphragms, FKM seals, and 316 stainless-steel bodies—are validated for intermittent exposure to THF, DMF, and acetonitrile; extended use requires vapor trapping and exhaust condensation.
Do ROCKER filtration manifolds support steam sterilization?
MultiVac300/600-MB and SolarVac601/1201-MB manifolds are rated for 121°C/20 psi autoclaving; aluminum-based MultiVac310/610-MS units are only steam-sanitizable (not sterilizable) per ISO 17665-1.
Is technical support available outside Taiwan?
ROCKER maintains authorized service centers in the US, Germany, Japan, and Singapore, with calibration and repair services traceable to NIST or DAkkS-accredited laboratories.
