FAQ
Q: Can the furnace operate continuously for extended periods?
A: Yes. The ZYLAB 4L Muffle Furnace is designed for both batch and continuous operation. The high-quality heating elements and insulation materials allow stable, long-duration heating cycles.
Q: What kind of atmosphere can be used inside the chamber?
A: This model operates in ambient air by default. However, for inert or controlled atmospheres (e.g., nitrogen, argon), we offer optional gas inlet ports and sealing upgrades. Please contact us for customization details.
Q: Can I customize the chamber size or voltage?
A: Yes, ZYLAB offers customizable chamber volumes and voltage options (e.g., 110V/220V) to match your specific laboratory or regional requirements.
Q: Is it safe to use the furnace in a standard lab environment?
A: Yes, it features a double-layer steel casing with active air cooling, ensuring the external surface remains below 50°C during operation—safe for use on lab benches and in educational or industrial lab settings.
Q: What is the delivery time and warranty policy?
A: Standard models are typically shipped within 5–7 working days. ZYLAB provides a 18-month warranty covering non-consumable parts and technical support throughout the product’s service life.
