WLD-Tec SteriMax Long 161 mm Infrared Loop Sterilizer
€713,00 excl. VAT
The WLD-Tec SteriMax Long 161 mm infrared loop sterilizer delivers dependable flame-free sterilization for inoculating loops, needles and microbiology tools.
Featuring an extended 161 mm ceramic heating tube, it accommodates longer instruments and repeat workflows.
High-temperature infrared heating eliminates microorganisms in seconds without flames, gas or alcohol — perfect for laminar flow cabinets and sterile workstations.
Seven angle positions and a robust stainless housing ensure ergonomic and safe daily use.
Trustworthy German engineering makes it ideal for microbiology labs, QA/QC departments and educational facilities.

WLD-Tec SteriMax Long 161 mm – Extended Infrared Loop Sterilizer for Longer Tools
The WLD-Tec SteriMax Long 161 mm infrared loop sterilizer is engineered for laboratories that require flame-free sterilization with an extended heating zone for longer loops, needles or spreaders.
Its advanced double tube design combines a abrasion-resistant ceramic annealing tube with a quartz heating element. When activated, infrared radiation brings the chamber to sterilization temperatures between 900–950 °C, enabling complete microbial elimination in just seconds without generating flames or combustion gases. This flame-free operation makes the SteriMax Long particularly well-suited for use under laminar flow cabinets, anaerobic workstations, safety cabinets and clean benches.
Designed for Extended Tools and Continuous Use
The 161 mm long heating tube provides a generous sterilization zone, so longer loops and instruments don’t need to be repositioned for full exposure. This increases throughput and improves workflow comfort, especially in high-productivity labs.
Seven adjustable angle positions (+30° / −45° increments) allow the heating chamber to be oriented for operator ergonomics and ideal access.
Built-In Safety and Ergonomic Operation
The sterilizer’s robust stainless-steel housing resists corrosive agents and UV, ensuring long service life in demanding environments. A rear splash shield improves operator safety when working with pathogenic materials.
A residual heat indicator warns when the chamber is still hot after use, and a simple control panel provides reliable, intuitive operation without complexity.
Trusted Quality and Low Operating Cost
WLD-Tec combines compact design with German engineering for high reliability and minimal maintenance. The flame-free infrared sterilization method not only enhances lab safety but also reduces consumables and service downtime compared to open-flame alternatives.
