What is the standard lead time for ordering hot and cold workstations, and do you offer on-site inspection and live testing?

The lead time for standard off-the-shelf models is approximately 15 business days Customized models have lead times determined by the complexity of the solution. We offer on-site inspection and in‑field prototype testing services; you can schedule a test appointment with our sales team in advance to verify on location whether the equipment’s performance meets your experimental requirements.

What is the warranty period for the entire Congtical hot-and-cold workstation, and what is the response time for after-sales service and repairs?

The entire machine is provided. 1-year free warranty , the core temperature-control components are covered by an extended warranty; the after-sales team provides 7×12-hour online response Domestic users can quickly troubleshoot issues remotely, and when necessary, on-site repairs will be arranged by engineers stationed nearby to ensure the equipment remains in normal working condition.

When equipment exhibits significant temperature fluctuations, fails to heat up, or fails to cool, how can you perform a preliminary troubleshooting?

You can perform a preliminary troubleshooting step as follows:

Check that the device’s power supply is stable and that the power and data cables are securely connected.
Clean any foreign matter from the sample stage and inspect the refrigeration unit for frost buildup or blockages.
Verify that the temperature-control software parameters are set correctly.
If the issue remains unresolved after troubleshooting, please contact our after-sales team for remote technical support.

Is the hot-and-cold stage noisy during operation, and are there any specific requirements for the laboratory environment?

The Congtical hot-and-cold workbench utilizes Silent Temperature Control and Cooling Module It operates with low noise, ensuring no disruption to routine laboratory activities. The equipment requires only standard 220V laboratory power and a clean environment free of highly corrosive gases, with no special environmental constraints.

What are the maximum sample size and load capacity of the hot/cold stage?

The standard model’s sample stage is compatible. Side length / diameter ≤ 20 mm For samples, the maximum load capacity is approximately 50 g. For large‑size, heavy‑weight samples, a custom‑designed, widened and thickened sample stage is available; please refer to the product manual or contact customer service for detailed specifications.

What is the calibration interval for the temperature of the hot‑and‑cold stage, and how is the calibration performed?

Suggestion Every 12 months Perform a temperature calibration to ensure temperature control accuracy. Our company provides dedicated calibration tools and detailed calibration instructions, enabling users to carry out calibration independently. We also offer support for third-party, accredited metrology institutions to perform calibration, thereby guaranteeing the precision and reliability of temperature data.

After the hot-and-cold workbench arrives, does installation and commissioning require on-site operation by qualified technicians?

The standard‑model hot/cold workbench comes with a detailed installation manual and instructional videos, allowing you to complete installation and commissioning on your own if you have basic laboratory equipment‑operation skills. If on‑site service is required, our company can dispatch qualified technicians to perform installation, commissioning, and provide hands‑on training at your location; please contact our sales team to confirm the scope of services.

What is the maximum heating and cooling rate of the temperature stage, and is this rate continuously adjustable?

Different models exhibit varying heating and cooling rates; standard models can achieve a maximum heating rate of up to 50℃/min , the maximum cooling rate can reach 30℃/min , all models in the series support both heating and cooling rates. Continuously and precisely adjustable from 0.1°C/min upward , which can meet various experimental requirements, such as slow constant-temperature heating and rapid temperature cycling.

Does the temperature range of the hot-and-cold stage support customization?

Customization supported. We can provide solutions tailored to your experimental setup and temperature‑zone requirements. Low-temperature, ambient-temperature, and high-temperature types Customized hot‑and‑cold stages are available, covering the temperature‑range requirements of most materials, biological, and metallographic experiments. For specific customization options, please contact our technical team for consultation and confirmation.

Which brands and models of optical microscopes are compatible with your hot‑and‑cold stage?

Our company’s hot-and-cold workstations utilize Standardized universal interface It is compatible with mainstream imported brands such as Leica, Zeiss, Olympus, and Nikon, as well as with both upright and inverted microscopes, metallurgical microscopes, and biological microscopes from leading domestic manufacturers. Custom adapters for specialized non‑standard interfaces can be tailored to meet specific requirements, ensuring broad compatibility.
