ZYLAB 27L Muffle Furnace

Introduction

ZYLAB 27L Muffle Furnace is a high-capacity benchtop furnace designed for demanding laboratory heat treatment tasks. With a maximum temperature of 1200°C and a spacious 27-liter ceramic fiber chamber, it allows for simultaneous processing of large or multiple samples, making it ideal for materials research, thermal testing, and routine analysis in academic and industrial labs.

Its user-friendly 7” touchscreen temperature controller, precise PID control, and robust construction ensure efficient, safe, and consistent heating performance.

Key Features

• Large 27L Chamber
  Accommodates bulkier or multiple samples at once, improving lab throughput and workflow efficiency.

• High-Temperature Performance
  Maximum temperature of 1200°C, with a recommended working range from room temperature to 1100°C, ideal for a wide range of thermal processing tasks.

• Smart Touchscreen Control
  Equipped with a 7-inch color touchscreen controller, offering intuitive operation and clear real-time display of the heating process. Supports storage of multiple temperature curves to avoid repeated settings across different experiments.

• Advanced Programmable Control
  Features 30-segment programmable temperature control for precise and automated heating cycles.

• Efficient Ceramic Fiber Chamber
  The furnace chamber is constructed from high-efficiency ceramic fiber, enabling fast heating rates, reduced power consumption, and excellent thermal insulation.

• Integrated Exhaust System
  Includes a top-mounted exhaust chimney, making the furnace suitable not only for standard heating but also for applications such as wax burning and ashing.

• Safe Double-Layer Casing
  The furnace body is designed with a double-layer steel structure and built-in cooling fan, keeping the outer surface temperature below 50°C to ensure operator safety.

• Low Power Consumption & Compact Design
  Designed with energy efficiency, lightweight construction, and a refined compact structure, this furnace is an ideal choice for material research laboratories and light industrial production.

Applications of 27L Muffle Furnace

• Ashing and loss-on-ignition analysis

• Ceramic and powder sintering

• Heat treatment of metal and non-metal samples

• Burnout and calcination of organic binders

• Thermal aging and material research

• Sample preparation for chemical testing (e.g., XRF, AAS)
