As we all know, the constant temperature shaker can be used for the precise cultivation of various organisms in scientific research and education departments such as plants, organisms, microorganisms, genetics, viruses, medicine, environmental protection, food, petroleum, chemical industry, the research of genetic engineering, and the heating of petrochemical industry.
Classification method:
1) Water bath, gas bath and oil bath are divided according to the assembly.
Gas bath constant temperature shaker: it is a biochemical instrument that combines a constant temperature gas box with an oscillator.
Water bath constant temperature oscillator is a biochemical instrument which combines temperature-controlled water bath with oscillator.
Oil bath constant temperature shaker is a biochemical instrument composed of oil bath tank and controllable temperature oscillator.
Among them, the maximum temperature control of the gas bath shaker is 70℃, usually 37℃.
Among them, the highest temperature control of water bath shaker 100℃
2) According to the vibration mode, it can be divided into rotary (laboratory), reciprocating and dual-function (rotary reciprocating).
3) According to the vibration frequency:
There are three common types: 30-200 rpm, 400-300 rpm and 60-400 rpm.
Wherein the oscillation frequency reaches 400 rpm. Because the oscillation frequency is relatively large, the requirements for triangular flask are high.
4) By volume: micro, constant and large.
5) According to the constant temperature range: low temperature (5-50℃) and normal temperature and high temperature.
6) According to layers: single layer and double layer.
7) According to the number of doors: single door and double door.
8) According to the display mode, it can be divided into digital display (only numbers can be displayed) and liquid crystal display (numbers and letters can be displayed).
9) According to the timing function, it is divided into timing and normally open.
10) According to the arrangement mode: vertical, desktop, stacked and floor-standing.
1 1) Are environmental protection points fluorine-containing and fluorine-free?
12) According to the heating power: below 999W,1000W-1999W; Above 2000W
13) According to the swing amplitude: φφ25mm (commonly used) and φ φφ50mm (large amplitude).
14) according to the power supply: 220V 50HZ 240V 50/60Hz (Thermo Fisher Scientific, USA).
15) According to the driving mechanism, it is divided into three-dimensional balanced eccentric wheel driving four-sided sliding bar driving mechanism.
16) according to the compressor, there are imported and domestic, high-quality fully enclosed compressors and air-cooled sealed compressors.
17) amplitude adjustment mode: multi-stage adjustable stepless adjustable.
