CDC recommends washing hands with soap and water whenever possible because handwashing reduces the amounts of all types of germs and chemicals on hands. But if soap and water are not available, using a hand sanitizer with at least 60% alcohol can help you avoid getting sick and spreading germs to others. The guidance for effective handwashing and use of hand sanitizer in community settings was developed based on data from a number of studies.

Shanghai Haozhuang Instrument Co., Ltd. develops the LNB brand constant temperature shaker, which is energy-saving and environmentally friendly, leading the country.
Instructions for use of water bath constant temperature shaker 1. Put in the test bottle and keep it balanced. If it is a dual-function model, set the oscillation mode.
2. Turn on the power and set the timing time according to the scale on the surface of the machine. If you need to work for a long time, adjust the timer to the "normally open" position.
3. Turn on the power switch and set the constant temperature:
(1) Place the small control switch in the "Setting" section. At this time, the temperature displayed on the display is the set temperature, adjust the knob, and set it to the temperature required for your work. (The working temperature you set should be higher than the ambient temperature, at this time the machine starts to heat up, the yellow indicator light is on, otherwise the machine does not work)
(2) Put the small switch of the control part at the "measurement" end. At this time, the temperature displayed on the display is the actual temperature of the air in the test box. As the temperature in the box changes, the displayed number will change accordingly.
(3) When the heating reaches your desired temperature, the heating will stop automatically and the green indicator light will be on; when the heat in the test chamber is dissipated and is lower than the temperature you set, a new round of heating will start again.
4. Turn on the oscillation device:
(1) Turn on the oscillation switch on the control panel, the indicator light is on.
(2) Adjust the oscillation speed knob to the desired oscillation frequency.
5. Turn off the power after working, and set the speed control knob and temperature control knob to the lowest point.
6. Clean the machine and keep it clean.
Air bath thermostatic shaker (also known as air thermostatic shaker) is a biochemical instrument that combines a temperature-controlled constant temperature incubator and an oscillator. It is mainly suitable for large and middle schools, medical treatment, petrochemical industry, health and epidemic prevention, Scientific research departments such as environmental monitoring are used for the oscillating cultivation of various liquid and solid compounds such as biology, biochemistry, cells and strains. Its main features: A: precise digital display of temperature control. B: There is an oxygen supply hole, and the constant temperature working chamber has sufficient oxygen supply. C: With mechanical timing. D: The universal spring test bottle rack is particularly suitable for the cultivation and preparation of biological samples for various comparative tests. E: Stepless speed regulation, stable operation, easy and safe operation. F: The inner cavity is made of stainless steel with good corrosion resistance.
Before using the air bath thermostat oscillator, please read this manual carefully.
2. The working plane of the machine should not be excessively smooth (such as tiles, etc.).
3. The electrical rated parameters of the socket provided by the user should not be less than the electrical rated parameters of the machine, and have good grounding measures.
4. The machine is strictly prohibited to be used in direct sunlight.
5. The speed regulation should start slowly from low speed to high speed.
6. The machine may have a certain displacement during high-speed oscillation, so someone should take care of it when using it.
Instructions for use 1. Load the test bottle and keep it balanced. If it is a dual-function model, set the oscillation mode.
2. Turn on the power and set the timing time according to the scale on the surface of the machine. If you need to work for a long time, adjust the timer to the "normally open" position.

Alcohol-based hand sanitizers can quickly reduce the number of microbes on hands in some situations, but sanitizers do not eliminate all types of germs.
Why? Soap and water are more effective than hand sanitizers at removing certain kinds of germs, like Cryptosporidium, norovirus, and Clostridium difficile1-5. Although alcohol-based hand sanitizers can inactivate many types of microbes very effectively when used correctly 1-15, people may not use a large enough volume of the sanitizers or may wipe it off before it has dried 14.
When using hand sanitizer, apply the product to the palm of one hand (read the label to learn the correct amount) and rub the product all over the surfaces of your hands until your hands are dry.
Swallowing alcohol-based hand sanitizers can cause alcohol poisoning.
Why? Ethyl alcohol (ethanol)-based hand sanitizers are safe when used as directed, but they can cause alcohol poisoning if a person swallows more than a couple of mouthfuls
