DC-4006 Low Temperature Thermostat, -40~100 °C, SHANGHAI SHENGUANG INSTRUMENT CO.,LTD (CAT#: STEM-GLE-4546-LGZ)

The microcomputer temperature-controlled low-temperature constant temperature tank adopts single-chip micro-processing control, self-tuning PID adjustment, imported high-precision platinum resistance (Pt100) temperature measurement, high temperature control accuracy and small fluctuation; The 40°C or 30L series adopts fully imported dual compressor cascade refrigeration technology and heat exchange system), which has high refrigeration efficiency and low noise. The instrument works stably and reliably, and the operation is convenient and safe.
User-friendly design: The folding handles on both sides are convenient for carrying the instrument, and the 20L and above series and the low temperature thermostat below -40°C adopt heavy-duty self-locking casters, which are easy to move. The low temperature constant temperature tank adopts advanced overall foaming process, which has good thermal insulation performance and effectively reduces the loss of cooling capacity.
Professional circulation stirring design: ensure that the liquid in the tank is evenly dispersed and smooth in the internal circulation, and the heat exchange is stable. The flow rate of the stirring pump in the low temperature constant temperature tank with a volume of more than 20L is 10L/min, the remaining 8L/min, the temperature fluctuation is ±0.05°C, and the display resolution is 0.1°C.
Suitable for internal/external temperature control applications: the sample can be directly placed in an open bath for constant temperature, or an external measurement unit that needs constant temperature can be controlled externally.
DC series cryogenic thermostats provide users with a high-precision, controlled, and uniform temperature constant field source. , a liquid environment with a uniform and constant temperature, the constant temperature test or test is directly carried out on the test sample or the produced product in the tank, which can be used for direct heating or cooling, as a temperature source for auxiliary heating or cooling, such as for the reaction kettle, automatic synthesis Temperature control of instruments, extraction and condensation units.
Application areas include constant temperature fields: sensor detection, constant temperature biochemical reactions, constant temperature material aging, etc. Biochemical field: rotary evaporator, Abbe refractometer, viscometer, rheometer, polarimeter, atomic absorption, ICP-MS, ICP, nuclear magnetic resonance, CCD, biological fermenter, chemical reactor (synthesizer), etc. Material field: electron microscope, X-ray diffraction, X fluorescence, vacuum sputtering plating, vacuum coating machine, ICP etching, various semiconductor equipment, fatigue testing machine, chemical deposition system, atomic deposition system, etc. Medical field: superconducting magnetic resonance, linear accelerator, CT, low magnetic field nuclear magnetic resonance, X-ray machine, microwave therapy machine, medical cold cap, cooling blanket, etc. Physical and chemical fields: lasers, magnetic fields, various molecular pumps, diffusion pumps, ion pumps, and the field of materials.
