Product Introduction
The product is the company and the Chinese Academy of Sciences research institute to develop the latest shaking of the apparatus used in a variety of gel staining, bleaching, gels, fixed, test Ust-blue staining and bleaching of the rock when the silver nitrate staining When fixed, stained, developing.autoradiography experiments in X-ray film for developing and fixing. Cellulose membrane after electrophoretic transfer to further treatment. Antigen - antibody response and staining, molecular hybridization. Cell culture and other needs in the solution can be used to the shaking of the experimental apparatus.
Are similar products in the advanced technology and reliable quality products, smooth running, low noise, vibration speed can be adjusted to regulate the range, can be equipped with a variety of flasks, to meet different customer needs, are biological and chemical, biological engineering, teaching, microbiological and medicine, industry research and production optimization equipment.
Variable speed, reliable, stable performance, no noise, stainless steel table, aesthetically beautiful and can be placed in the use of low temperature and incubator.

一.Use Method：
   Decolorization shaker would work on a smooth interface, gently downward pressure，The bottom four suction device will automatically suck the table.If the equipment working position, to be uprooted suckers one by one, before moving。power supply 220V 50Hz, the power switch to "NO" position, the indicator lights. Regulation, "speed adjustment" knob, select the appropriate frequency can rock work. Work surface can bear the weight of two kilograms or so for normal experiments. Unplug end of the experiment to ensure the safety.

二.Decolorization shaker should be stored in a dry, ventilated place without corrosive gas. Do not pile heavy objects on top of work surface. Test solution immediay after the spill dry.
