Overview

Electric sand bath, as an efficient and precise heating device, has been widely used in many laboratories. But users need to strictly follow the operating procedures during use in order to better utilize the equipment.

Product Details

The electric sand bath is a kind of laboratory equipment, which is mainly used to homogenize and heat samples. By placing the samples in the conductive sand and adjusting the current and voltage output by the power supply, the temperature of the samples can be controlled to meet various experimental requirements.

1. Product principle

By utilizing the thermal conductivity of conductive sand, the heat energy emitted by the heater is evenly transferred to the sand particles, and then transferred to the sample through the sand particles, achieving the goal of rapid and uniform heating. The electric sand bath uses an electric heater for heating, and its output power is processed by a circuit and controlled to a suitable range, so that the temperature of the sample is accurately controlled at the set value to complete various experiments.

2. Structural characteristics

The equipment mainly consists of three parts: heater, temperature control, and display. The heater is the core component of the entire equipment, using high-temperature alloy electric heating wires or silicon carbide heating elements, wrapped with a layer of thermal conductive material on the outside, and then sealed in a stainless steel box. The temperature controller adopts intelligent PID algorithm to achieve fast and accurate temperature control through voltage feedback and pulse width modulation technology. The monitor can display the set temperature and actual temperature in real time through LCD display, making it easy for the operator to monitor the experimental process.

3. Advantages of use

(1) Safe and reliable. Unlike traditional equipment such as flames and alcohol lamps for heating, electric sand baths use electric heaters that are free from open flames and pollution, and do not produce harmful gases and dust. They are safe and reliable to operate.

(2) High precision and uniform temperature. The temperature sensor and controller can accurately control the temperature of the sample, and the heater can evenly transfer heat to the sand particles, which in turn evenly transfer heat to the sample, avoiding local overheating or overcooling, resulting in more accurate experimental results.

(3) The adjustment range is wide, and parameters such as voltage, current, and power can be adjusted as needed. The sample heating temperature can reach over 300 ℃, which can meet the needs of most experiments.

(4) Easy to clean. The electric sand bath is enclosed in a stainless steel box and thermal conductive sand, which will not adhere to samples and impurities. After use, it can be easily cleaned with a brush or vacuum cleaner for easy maintenance and upkeep.

4. Operating procedures

(1) Connect and install according to the power requirements in the equipment manual, and turn on the power after confirming that there are no errors.

(2) Place the test sample at the center of the heater, ensuring a large contact area between the sample and the sand particles, and ensuring that there is no tight contact between the sample and the heater.

(3) Set the temperature according to the experimental requirements, confirm the set value, and press the "start" button to start heating.

(4) During the heating process, users need to constantly monitor the temperature value on the display screen and adjust it as needed.

(5) After the experiment, turn off the power and wait for the equipment to cool down before cleaning and maintenance.
