1. Introduction
This manual provides instructions for the safe and efficient operation of the Jingxin Technology JX100-2 Mini Dry Bath Incubator. The JX100-2 is a high-temperature dry-type thermostat controlled by a microcomputer, designed for precise temperature control in laboratory applications. It utilizes high-purity aluminum material as a heat-conducting medium, offering a wide temperature control range and high accuracy.
It is suitable for various applications including sample preservation and reaction, DNA amplification, electrophoresis pre-denaturation, and serum coagulation. The device features a two-level redundant hardware circuit design with an intelligent soft algorithm for stable and reliable operation, instant temperature display, and time decrement display.
2. Safety Information
- Always connect the instrument to a grounded power outlet.
- Do not operate the instrument if the power cord is damaged.
- Ensure proper ventilation around the unit to prevent overheating.
- Avoid spilling liquids onto the control panel or internal components.
- Do not touch the heating block when it is hot. Allow it to cool down before handling.
- Disconnect power before cleaning or maintenance.
- This instrument is designed for laboratory use only.

3. Product Overview
3.1 Components
The JX100-2 Mini Dry Bath Incubator consists of the main unit, a heating block module, and a power cord. The main unit houses the control panel, LED display, and heating elements.
Figure 1: JX100-2 Mini Dry Bath Incubator with various sample tubes and heating block modules. The main unit features an LED display and control buttons. Several aluminum heating blocks are shown, designed to hold different sizes of test tubes and centrifuge tubes.
3.2 Control Panel
The control panel features an LED display for temperature and time, along with buttons for setting parameters.
- LED Display: Shows current temperature and remaining time.
- Up/Down Arrows: Adjust temperature and time settings.
- Set Button: Enters setting mode.
- Start/Stop Button: Initiates or halts the heating process.
4. Setup
- Unpacking: Carefully remove the incubator and all accessories from the packaging. Inspect for any damage.
- Placement: Place the unit on a stable, level surface in a well-ventilated area, away from direct sunlight or heat sources. Ensure adequate space around the unit for air circulation.
- Module Installation:
- Ensure the unit is powered off and cool.
- Gently place the desired heating block module (e.g., MD06 for 16 x 15mm tubes) into the chamber of the main unit. Ensure it sits flush.
- The module is designed for convenient replacement, allowing for easy cleaning and disinfection.
- Power Connection: Connect the power cord to the back of the unit and then to a grounded AC 100-220V, 50/60Hz power outlet.
5. Operating Instructions
- Power On: Turn on the main power switch, usually located at the back or side of the unit. The LED display will illuminate.
- Setting Temperature:
- Press the Set button. The temperature display will flash.
- Use the Up and Down arrow buttons to adjust the desired temperature. The temperature control range is from room temperature +5°C to 130°C.
- Press Set again to confirm the temperature.
- Setting Time:
- After setting the temperature, press the Set button again. The time display will flash.
- Use the Up and Down arrow buttons to adjust the desired incubation time (up to 99 hours and 59 minutes).
- Press Set again to confirm the time.
- Starting Operation:
- Place your samples in the appropriate tubes and insert them into the heating block module.
- Press the Start/Stop button to begin the heating and incubation process. The display will show the current temperature and countdown timer.
- Stopping Operation:
- To stop the process before the timer expires, press the Start/Stop button.
- When the set time elapses, the unit will automatically stop heating and emit a buzzer alarm.
- Temperature Deviation Calibration: The unit supports temperature deviation calibration for enhanced accuracy. Refer to the specific calibration procedure in the advanced settings menu, if available, or contact technical support for guidance.
6. Maintenance
- Cleaning:
- Ensure the unit is powered off and completely cool before cleaning.
- Wipe the exterior surfaces with a soft, damp cloth. Do not use abrasive cleaners or solvents.
- The heating block modules can be removed for easy cleaning and disinfection. Clean them with appropriate laboratory detergents and rinse thoroughly. Ensure they are completely dry before re-inserting.
- Module Replacement: Modules can be easily interchanged to accommodate different tube sizes. Always ensure the unit is cool before replacing modules.
- Storage: When not in use for extended periods, store the incubator in a clean, dry environment.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Unit does not power on. | No power supply; Power cord loose or damaged; Power switch off. | Check power connection; Ensure power switch is on; Replace power cord if damaged. |
