Product overview
Labotemp Cryogenic Test Chamber CTC-05 is a liquid nitrogen–cooled test chamber designed for controlled low-temperature specimen conditioning prior to pendulum impact tests (e.g., Charpy) in accordance with international standards. The chamber operates from +30°C down to −196°C, combining a heat-balance circulation principle with forced-air convection to ensure uniform cooling and stable specimen temperature. Liquid nitrogen refrigeration enables rapid cooling; digital temperature resolution of 0.1°C supports precise conditioning. The chamber is constructed in stainless steel and accommodates up to 60 specimens with independent sample loading.

Key benefits

• Ultra-low temperature capability down to −196°C for reproducible specimen conditioning
• Uniform cooling via circulating airflow and forced convection for consistent temperature distribution
• Designed to meet international impact-test requirements (e.g., Charpy / GB/T 229)
• Independent single-specimen access without disturbing other samples

Features

• Liquid nitrogen refrigeration technology achieving temperatures to −196°C
• Heat-balance circulation with forced convection and circulating fan system
• High-performance digital temperature control (resolution 0.1°C) and ±2°C control accuracy
• Capacity for more than 60 specimens with independent loading
• Imported cryogenic solenoid valve for stable cooling performance
• Stainless-steel construction for corrosion resistance and durability
• Digital timer: 1 min to 9999 min (resolution 1 min)
• Simple operation and stable thermal performance

Applications

• Specimen cooling and conditioning for Charpy pendulum impact tests under ultra-low temperatures
• Suitable for metallurgical laboratories, materials testing centers, quality-control departments and research institutions
• Applicable to other low-temperature testing and detection requirements
