Overview
The WIGGENS ChemVak C300 is a chemically resistant, oil-free diaphragm vacuum pump engineered for reliable operation in aggressive laboratory environments where exposure to corrosive vapors, acidic or basic condensates, and organic solvents is routine. Based on positive displacement principle, the pump employs a PTFE-coated diaphragm and valve system to isolate the drive mechanism from the gas stream—ensuring zero oil contamination, minimal maintenance, and extended service life under sustained chemical stress. Unlike rotary vane or water aspirator systems, the C300 eliminates disposal of hazardous waste oil and conserves water resources while delivering stable vacuum performance up to 100 mbar (75 Torr). Its sealed dual-chamber architecture physically separates the pneumatic cavity from the motor and transmission components, preventing corrosion-induced mechanical failure and supporting compliance with ISO 8573-1 (compressed air purity) and GLP-aligned lab infrastructure requirements.
Key Features
- Full wetted-path construction using chemically inert polytetrafluoroethylene (PTFE), including diaphragm, valves, gaskets, and internal tubing—validated for compatibility with HCl, HF, HNO₃, NaOH, acetone, chloroform, and other aggressive media per ASTM D543 and DIN EN ISO 1746.
- Integrated thermal cut-off protection: automatic shutdown at elevated motor temperature (>85 °C), followed by self-restart upon cooling—enhancing operational safety and long-term reliability in unattended applications.
- Low-noise operation (<50 dB[A]) achieved via precision-balanced eccentric drive and vibration-dampening elastomeric mounting—suitable for shared lab spaces and laminar flow hoods.
- Compact footprint (233 × 110 × 210 mm) and lightweight design (6 kg) facilitate benchtop integration with rotary evaporators, filtration manifolds, and vacuum ovens without structural reinforcement.
- Single-stage diaphragm configuration optimized for moderate vacuum demands (100 mbar), offering high volumetric efficiency at low power draw (60 W, 0.8 A).
Sample Compatibility & Compliance
The ChemVak C300 is validated for continuous duty with vapor-phase and condensed-phase challenges typical in pharmaceutical synthesis, analytical sample preparation, and fine chemical processing. It meets IEC 61000-6-3 (EMC emission standards) and carries CE marking under the EU Machinery Directive 2006/42/EC and Low Voltage Directive 2014/35/EU. While not intrinsically safe for Zone 1/2 explosive atmospheres, its PTFE-wetted path conforms to USP guidance for equipment qualification in regulated QC labs. The pump is compatible with ISO-KF 10 mm vacuum fittings and supports installation of optional inlet filters (e.g.,订货号 169311-06) to capture particulates and regulate vacuum pressure—critical for reproducible solid-phase extraction and gel drying protocols.
Software & Data Management
As a standalone mechanical vacuum source, the C300 operates without embedded firmware or digital interfaces. However, it is fully interoperable with third-party vacuum controllers and monitoring systems via analog or digital signal inputs. When paired with the optional DVM150C digital vacuum gauge (PTFE-ceramic sensor, 0.1 mbar resolution, 0.1–1000 mbar range), users gain traceable, audit-ready vacuum logging compliant with FDA 21 CFR Part 11 when integrated into validated LIMS or ELN platforms. The DVM150Pro variant (Pirani sensor, 0.001 mbar resolution) enables precise mid-vacuum process control during solvent removal or freeze-drying pre-conditioning stages.
Applications
- Vacuum-assisted filtration of aggressive filtrates (e.g., acidic leachates, alkaline hydrolysis mixtures)
- Rotary evaporation of halogenated solvents and low-boiling organics under controlled vacuum
- Reduction-pressure distillation of thermally sensitive compounds in API manufacturing
- Gel electrophoresis apparatus drying and vacuum desiccation of hygroscopic standards
- Sample concentration via centrifugal vacuum evaporation (e.g., SpeedVac®-compatible workflows)
- Replacement of water-jet aspirators in sustainability-focused laboratories seeking ISO 14001-aligned resource conservation
FAQ
Is the C300 suitable for pumping hydrogen chloride (HCl) gas?
Yes—the entire gas path is constructed from PTFE and FKM elastomers, which exhibit excellent resistance to anhydrous and aqueous HCl per NACE MR0175/ISO 15156 assessments.
Can the pump be used continuously for 24/7 operation?
It is rated for intermittent duty (up to 8 hours/day); for continuous operation, thermal management and inlet filtration must be verified per application-specific risk assessment.
Does the C300 require periodic oil changes or lubrication?
No—it is a true oil-free diaphragm pump; no lubricants contact the gas stream or moving parts.
What is the expected service life of the diaphragm under standard lab conditions?
Typical diaphragm lifetime exceeds 10,000 operating hours when used within specified vacuum and temperature limits and protected by an inlet filter.
Is the C300 compatible with vacuum-controlled reactors or automated synthesis platforms?
Yes—its stable flow profile and electrical interface (IEC 60320 C14 inlet) allow integration with PLC-controlled vacuum manifolds and PID-regulated vacuum loops via external solenoid valves or proportional controllers.
