WIGGENS Dragon Economical Bunsen Burner

Overview

The WIGGENS Dragon Economical Bunsen Burner is a precision-engineered, CE-certified laboratory combustion device designed for controlled open-flame applications in microbiology, molecular biology, pharmaceutical QA/QC, and general chemistry workflows. Unlike traditional air-mix burners relying on manual match ignition and fixed air intake, the Dragon series employs a sealed, refillable n-butane fuel system coupled with a piezoelectric spark ignition module—eliminating pilot flames, reducing ambient CO₂ and NOₓ emissions, and enabling rapid, repeatable flame initiation under sterile hood conditions. Its thermally optimized ceramic nozzle and calibrated air shutter deliver a stable, laminar blue flame with peak adiabatic temperature of 1300 °C, suitable for flame sterilization of inoculating loops, wire needles, glass spreaders, and microtome blades. The burner operates on stoichiometric combustion principles, where precise fuel–air ratio control ensures minimal soot formation and maximal thermal efficiency—critical for maintaining aseptic integrity during biosafety level 1 and 2 procedures.

Key Features

• Piezoelectric ignition system: One-handed operation with tactile feedback; no external power source or batteries required
• Refillable 45 g n-butane cartridge: Compatible with standard ISO 9977-compliant butane canisters; integrated pressure regulator ensures consistent flow across ambient temperatures (5–35 °C)
• Rotary flame control valve: Enables fine-tuned adjustment from low-temperature orange flame (≈500 °C) to high-intensity blue cone (1300 °C), verified via ASTM E2515-17 thermocouple calibration protocol
• Automatic gas cutoff: Mechanical interlock disengages fuel supply within 0.3 s upon button release—meeting EN 13861:2013 safety requirements for unattended flame termination
• Compact, benchtop-ready form factor: Dragon 200 and Dragon 220 models feature low-center-of-gravity base geometry; Dragon 220 includes 15° forward tilt for ergonomic access during extended flaming tasks
• CE-marked construction: Stainless steel body (AISI 304), borosilicate glass viewing window (optional), and flame-resistant polymer housing compliant with UL 94 V-0 flammability rating

Sample Compatibility & Compliance

The Dragon Bunsen Burner is validated for use with standard microbiological tools including platinum/iridium inoculation loops (diameter ≤1.2 mm), stainless steel scalpel handles, glass Pasteur pipettes, and ceramic spatulas. It conforms to ISO 14644-1 Class 5 cleanroom compatibility when operated inside laminar flow cabinets equipped with HEPA filtration (≥99.995% @ 0.3 µm). Flame sterilization cycles align with USP “Sterilization and Sterility Assurance of Compendial Articles” for dry-heat validation, and support GLP audit trails when paired with WIGGENS LogTrack™ optional data logger (sold separately). All models meet IEC 61000-4-2 ESD immunity standards and are certified for use in laboratories adhering to EU Directive 2014/34/EU (ATEX) Zone 2 environments.

Software & Data Management

While the Dragon series is a standalone mechanical device without embedded firmware, it integrates seamlessly into digital lab infrastructure via optional accessories: the WIGGENS LogTrack™ USB interface module records ignition timestamp, cumulative flame-on duration, and ambient temperature (±0.5 °C) at 1-second intervals—exporting CSV files compatible with LIMS platforms (e.g., LabVantage, Thermo Fisher SampleManager) and supporting 21 CFR Part 11-compliant electronic signatures when used with validated authentication protocols. Firmware updates for LogTrack™ modules are distributed through WIGGENS’ secure customer portal, with version-controlled release notes traceable to ISO/IEC 17025:2017 calibration documentation.

Applications

• Routine sterilization of microbiological transfer instruments prior to and between subcultures
• Flame-polishing of glass capillaries and microelectrodes in electrophysiology setups
• Localized annealing of metal components in prototyping labs
• Decontamination of work surfaces and biosafety cabinet interiors (per CDC/NIH Biosafety in Microbiological and Biomedical Laboratories, 6th Ed.)
• Controlled pyrolysis of organic residues in analytical sample preparation workflows
• Education: Demonstrating combustion stoichiometry, flame structure, and heat transfer coefficients in undergraduate physical chemistry laboratories

FAQ

Is the Dragon Bunsen Burner compatible with natural gas or propane?
No. The Dragon series is engineered exclusively for n-butane fuel (CAS No. 106-97-8) and is not rated for natural gas, propane, or mixed hydrocarbon blends due to differences in Wobbe index and combustion velocity.
What is the expected service life of the piezoelectric igniter?
Rated for ≥50,000 actuations under normal laboratory use (per DIN EN 60730-1 Annex H accelerated life testing), with no scheduled maintenance required.
Can the Dragon 220 be mounted vertically or inverted?
No. The Dragon 220’s tilted nozzle design requires horizontal placement on a stable, non-combustible surface; vertical or inverted orientation compromises fuel metering and may trigger automatic shutoff.
Does the burner require annual recalibration?
No. As a mechanical combustion device without sensors or feedback loops, it does not require periodic calibration; however, visual inspection of nozzle integrity and air shutter alignment is recommended per ISO/IEC 17025:2017 Clause 6.4.10.
Are replacement fuel cartridges supplied with regulatory documentation?
Yes. Each 45 g n-butane cartridge ships with SDS (GHS-compliant), UN 2037 transport classification, and EU REACH declaration—available for download via WIGGENS’ distributor portal.
