Laboratory incubator ZXSD-B1270

for bacteria culturesforced convectionrefrigerated

Overview
The ZXSD-B1270 BOD incubator is a cooled laboratory incubator designed for BOD determination and general microbiological incubation where accurate and stable temperature control is required. The unit offers a wide working range and programmable temperature segments with PID regulation for precise control.

Backup and reliability
The series includes a backup program and non-volatile memory to retain settings in case of power failure, allowing experiments to resume under the same conditions after interruptions. The cooling compressor runs continuously with solenoid valve control for improved regulation below ambient temperatures.

Key features

• P.I.D. microprocessor control for precise temperature maintenance in fixed and program modes.
• Large LCD for temperature display and program navigation.
• Three-dimensional heating and forced air circulation for uniformity of ±0.5°C @ 37°C and temperature accuracy to ±0.1°C.
• Low-noise cooling system using CFC-free refrigerant; automatic defrosting with minimal ice formation.
• 3-step adjustable fan speed to reduce sample/media drying and tailor the incubation environment.
• Real-time electronic timer (0–9999 mins) and password protection for parameter security.
• Triple safety protections and independent devices for over-temperature, over-current and leakage protection.
• Standard: outer door with double-layer tempered observation window, inner heat-resistant glass door, fluorescent lamp, Ø50 mm test port and 2 grids; optional printer, UV lamp, RS-232/RS-485 interfaces.

Applications

• BOD (Biochemical Oxygen Demand) determination and water analysis laboratories.
• Incubation of microorganism cultures and enzymatic assays.
• Sample preservation, insect culture (e.g., Drosophila) and other temperature-sensitive protocols.
