WIGGENS Dragon 200 Portable Butane Bunsen Burner

Overview

The WIGGENS Dragon 200 is a compact, portable, and laboratory-grade butane-fueled Bunsen burner engineered for precise thermal control in routine and field-based scientific applications. Unlike traditional fixed-gas-line burners, the Dragon 200 integrates a sealed, refillable butane cartridge system with an integrated piezoelectric ignition mechanism—eliminating the need for external gas infrastructure or match-based lighting. Its operation is grounded in the classic Bunsen principle: premixing fuel vapor with ambient air prior to combustion within a calibrated venturi tube, enabling stable, non-luminous, high-temperature blue flames ideal for sterile heating, flame sterilization, glassworking, and small-scale metal joining. Designed and manufactured in Germany to stringent DIN EN ISO 9001 quality standards, the Dragon 200 complies with European safety directives for portable gas appliances (EN 521:2018) and meets laboratory-specific requirements for flame stability, thermal reproducibility, and operator safety under controlled indoor conditions.

Key Features

• Electronic piezoelectric ignition system ensures reliable, spark-based flame initiation without external power sources or consumables.
• Continuously adjustable air shutter and needle valve allow fine-tuned control over flame stoichiometry, enabling transition between oxidizing (hotter, blue), neutral, and reducing (cooler, slightly luminous) flame regimes.
• Integrated 45 g refillable butane cartridge provides up to 60 minutes of continuous operation at nominal heat output—optimized for intermittent use across multiple experiments per charge.
• Robust, chemically resistant polymer housing with stainless steel burner tube and precision-machined brass air inlet ensures long-term dimensional stability and corrosion resistance in humid or solvent-rich lab environments.
• Compact footprint (92 × 115 × 79 mm) and low net weight (407 g) support tabletop deployment, mobile lab setups, teaching demonstrations, and field-deployable sterilization workflows.
• No external gas line required—operates independently using commercially available butane canisters compliant with EN 417 specifications.

Sample Compatibility & Compliance

The Dragon 200 is compatible with standard microbiological loops, inoculating needles, wire gauze, crucibles, glass rods, and small metallic tools requiring localized thermal treatment. It is routinely employed in accordance with CLSI M22-A3 and USP guidelines for flame-based sterilization of inoculation instruments prior to aseptic transfer. The device conforms to IEC 61010-1:2010 for electrical safety (ignition circuit) and EN 13861:2013 for laboratory gas appliance risk assessment. Flame temperature calibration is traceable to NIST-standard thermocouple reference data; validated maximum output of 1350 °C (with LPG) aligns with ASTM E2550–21 specifications for high-temperature thermal verification in benchtop equipment.

Software & Data Management

As a manually operated, analog thermal instrument, the Dragon 200 does not incorporate embedded firmware, digital interfaces, or data logging capabilities. All operational parameters—including flame height, air-to-fuel ratio, and thermal output—are adjusted physically via tactile controls. This design intentionally avoids electronic complexity to ensure compliance with GLP and GMP environments where audit trails, cybersecurity validation, and software lifecycle documentation are not applicable. No FDA 21 CFR Part 11 requirements apply. Maintenance records, calibration checks (e.g., flame temperature verification using pyrometric cones or IR thermography), and usage logs may be maintained externally in laboratory notebooks or LIMS-compatible spreadsheets.

Applications

• Sterilization of microbiological inoculation loops and needles in teaching labs and clinical microbiology workflows.
• Localized heating of reaction vessels during qualitative organic analysis or small-scale synthesis.
• Flame annealing of platinum or nichrome wires used in electrochemical cell construction.
• Sealing glass capillaries and tubing in histology and microfluidics preparation.
• Thermal disinfection of surface tools in biosafety cabinets (BSC Class II) when external gas lines are prohibited.
• Field-based veterinary or environmental sampling where portability and infrastructure independence are critical.

FAQ

Is the Dragon 200 compatible with natural gas supply lines?

No—the Dragon 200 is designed exclusively for portable butane cartridges or LPG cylinders. It is not configured for connection to fixed natural gas plumbing systems.
Can the butane cartridge be refilled in-house?

Yes—using standardized butane refill kits compliant with EN 417, though refilling must be performed in well-ventilated areas away from ignition sources and in accordance with local hazardous materials handling regulations.
What safety certifications does the Dragon 200 hold?

It carries CE marking per Directive 2014/68/EU (PED) and Directive 2014/35/EU (LVD), and conforms to EN 521:2018 for portable gas burners used in non-domestic settings.
Does the burner require periodic recalibration?

While no formal calibration interval is mandated, users should verify flame stability and maximum temperature annually using reference thermocouples or Seger cones, especially after mechanical impact or extended storage.
Is replacement tubing or spare cartridges available through WIGGENS?

Yes—WIGGENS offers certified butane cartridges (Art. No. WG-BC45), replacement burner tubes (WG-BT-D200), and flame diffuser caps as genuine OEM accessories under warranty support terms.
