short description:

The low-temperature cooling liquid circulator (or low-temperature constant temperature bath) is an efficient temperature control device. It achieves temperature control and heat transfer by circulating low-temperature coolant, featuring high energy efficiency, easy operation, and stable reliability. It is ideal for environments that require precise temperature control in space-limited settings. It is widely used in laboratories, pharmaceuticals, chemicals, semiconductors, and other fields requiring stable low-temperature environments.

Temperature Range: 5°C to 35°C, dual-function cooling and heating. The combination of the heater and cooling compressor with built-in sensors utilizes PID control technology, providing temperature control precision of ±0.1°C.

1. LCD display, touch screen operation, quick temperature and differential settings, one-click start for circulation and temperature control.
2. Top liquid addition, rear liquid drainage, and overflow outlet, with a front intuitive liquid level display window.
3. Proportional cooling technology adjusts output based on demand, accurately controlling the compressor and heater power for energy-efficient operation.
4. High-efficiency insulation materials reduce heat exchange, ensuring stable temperatures and improved energy efficiency.
5. The circulating water system is equipped with multiple purifiers to prevent impurities from entering the pump system, extending the pump’s lifespan.
6. A powerful circulation pump ensures uniform coolant flow, providing continuous and stable cooling effects.
7. Quick response to load and temperature changes ensures the system temperature remains within the set range, offering strong adaptability.
8. Built-in heat dissipation fan and perforated shell for fast heat dissipation, preventing component overheating and maintaining stable operation.
9. Environmentally friendly refrigerants that are non-toxic and non-polluting, ensuring excellent and stable cooling performance.
10. Low-speed compressor operation reduces wear and extends lifespan.
11. High-quality compressor paired with a quiet fan results in low operational noise, making it suitable for quiet laboratory environments.
12. The front panel is easily removable for filter cleaning, and the rear drainage valve design supports quick drainage. Installation and debugging are convenient and fast.
13. The unit has caster wheels with locking devices at the bottom, making it easy to move. Its compact size saves space.

Applications:

1. Chemical Materials Research
2. Polymer Chemical Polymerization Reactions
3. RAFT polymerization to prepare block copolymers requires temperature control of the reaction vessel jacket at 30±0.1°C. Temperature fluctuations can cause a widening of the molecular weight distribution (PDI). The high-precision cooling water system connects to the glass reaction kettle to maintain the polymerization degree and molecular weight within a small range.
4. Nanomaterial Synthesis
5. The seed-growth method for preparing nanoparticles requires the growth solution to be maintained at 25±0.1°C for 12 hours. Temperature deviation of less than 0.3°C ensures that the particle aspect ratio grows uniformly. The high-precision cooling system and jacketed glass constant temperature bath maintain a deviation of less than 3% in nanoparticle size.
6. Life Sciences
7. Protein Purification Systems
8. Temperature control for affinity chromatography columns in protein purification systems is critical. With traditional chillers having ±1°C fluctuations, protein aggregation and reduced recovery rates occur. Using the high-precision chiller to maintain 10±0.1°C significantly improves these issues.
9. Fluorescence-Based Enzyme Assay
10. In enzyme kinetics research with 96-well plates, enzyme reactions need to be monitored continuously at 30±0.1°C. Temperature differences between wells exceeding 0.2°C can lead to data scatter. Connecting the enzyme reader to the high-precision cooling water temperature control module can reduce the CV value to below 2%
