Product Introduction：
SG-3025-type  oscillator is based on the views of the majority of users, technical personnel from the company designed new products. Widely used in various tertiary institutions, environmental protection, scientific research, health, disease prevention, petroleum, chemical, and other units of the laboratory, it has the shape and generous, large capacity, low noise, light weight, small size and other characteristics, speed adjustable, and with a timing device, is an ideal laboratory staff the necessary tools. SG-3025S-based a number of significant speed and more functions, user-friendly control oscillation speed precision and control of experimental conditions, to meet user demand for precision experiments.

Features:：
一：Use Method
1: First of all, will need to oscillation of container （bottle） into the oscillating plate spring in the solution container can not exceed one-third of the container, or to Stoppering.
2: This time knob, rotating the ON （normally open） position or location of the specified time you need.
3: The speed control knob clockwise rotation to a minimum speed position and turn the power switch, power indicator light, then speed control knob clockwise to your desired rate of rotation.
二：Notes
1. The machine adopts 3 safety sockets, be sure to use ground connected properly.
2.The work should be placed in the formation of this solid machine the table, to prevent vibration.
3.spring clamp fixed only for use in small and medium flask, large containers should be removed accordingly crossing a spring or other means to reinforce.
4.The machine should turn off after use, dry and ventilated place and keep it clean.
