Mini CNC constant temperature metal bath

Mini CNC constant temperature metal bath

CNC constant temperature metal bathIt is a laboratory equipment that combines microcomputer control technology with high-precision temperature regulation function. It uses metal materials (such as aluminum and copper) as thermal conductive media to achieve fast, stable, and accurate temperature control. It is widely used in fields such as biochemistry, molecular biology, pharmaceuticals, and food safety.

1、 Working principle

1. Thermal conduction and electric heating
   The device converts electrical energy into thermal energy through heating elements (such as semiconductor Peltier effect modules or resistance wires), and metal modules (such as aluminum blocks) act as thermal conductive media, utilizing their high thermal conductivity (aluminum's thermal conductivity is about 237 W/(m · K)) to quickly and uniformly transfer heat.

2. Closed loop control system

• temperature sensorReal time monitoring of metal module temperature (such as PT100 platinum resistance sensor, accuracy ± 0.1 ℃).

• Microcomputer controllerCompare the sensor feedback data with the set temperature, adjust the heating power through PID algorithm, and achieve dynamic balance.

2、 Core Features

1. High precision temperature control

• The temperature range is usually from room temperature+5 ℃ to 120 ℃, with an accuracy of ± 0.1 ℃, strong stability, and reduced experimental errors.

• Example: In PCR amplification, strict temperature control is required at each stage of denaturation (95 ℃), annealing (55-65 ℃), and extension (72 ℃), and the metal bath can ensure that the temperature fluctuation is less than 0.5 ℃.

2. quick response

• Metal has a low thermal capacity and a much faster heating rate than water baths (for example, it only takes 2-3 minutes to rise from 25 ℃ to 95 ℃, while water baths take more than 10 minutes).

• Suitable for experiments that require rapid temperature switching, such as enzyme activity assays and protein denaturation studies.

3. Safety and hygiene

• Dry heatingThere is no risk of water overflow, avoiding electric shock hazards, and no microbial contamination (water bath is prone to bacterial growth).

• corrosion prevention designThe surface of the metal module has been specially treated to resist chemical corrosion and is suitable for long-term exposure to acidic and alkaline solutions.

4. Modularity and Convenience

• Can replace heating modules of different specifications (such as test tube racks, PCR tube racks, microplate modules) and adapt to various experimental containers.

• Compact design saves space, and some models support mobile use (such as quick sample processing after field sampling).

5. intelligent functions

• Preset temperature curve: supports multi-stage program temperature control (such as gradient PCR requiring multiple temperature platforms to be set).

• Timer function: Automatically stop heating to avoid sample overheating.

• Communication: The entire metal bath system of Guoli Tian Company supports RS485 communication.

3、 Typical application scenarios

1. molecular biology

• PCR amplificationProvide precise temperature environment for DNA double strand denaturation, primer annealing, and DNA polymerase extension.

• Enzyme digestion and ligationRestriction endonucleases and DNA ligases require specific temperatures (such as 37 ℃) to maintain their activity.

2. Biochemistry

• Protein researchProtein denaturation (such as coagulation of serum proteins by heating at 56 ℃), enzyme activity measurement (such as measuring enzyme activity at 30 ℃).

• nucleic acid extractionThe steps of cell lysis and removal of DNA binding proteins require constant temperature incubation.

3. Pharmaceutical and Quality Inspection

• Drug stability testingSimulate different temperature conditions (such as accelerated testing at 40 ℃) to evaluate the shelf life of drugs.

• Microbial testingEnrichment culture of pathogenic bacteria in food samples (such as incubation of Salmonella at 37 ℃).

4. Materials Science

• Melting point determinationDetermine the melting point of materials through heating curves (such as DSC analysis of polymer materials).

• Thermal aging testEvaluate the performance changes of materials at high temperatures (such as heat resistance testing of rubber).
