First, safety instructions
1. Before starting to use the instrument, please read the instrument manual supplied with IKA® to familiarize yourself with the operation and performance of the instrument.
2. Make sure that the instrument input voltage is the same as the voltage indicated on the instrument nameplate. The power outlet must be grounded.
3. Before starting the machine, pay attention to whether the heating temperature of the heating pot is reasonable. The safe temperature of the heating pot should be at least 25 °C lower than the burning point of the treated medium.
4. Do not operate the instrument in an explosive environment or under water.
5. To prevent the accumulation of pressure, the glass components should be kept ventilated when operating under normal pressure conditions (eg, not working).
Second, the reasonable use of heating and cooling media
1. If the temperature of the heating pot is higher than 80 °C, it is recommended to use 50mpas silicone oil as the heating medium. Within 80 ° C, deionized water was used as the heating medium.
2. Inject 2/3 volume of deionized water or silicone oil (about 2L) into the heating pot to ensure that the heating medium of the heating pot is enough to submerge 2/3 of the evaporation bottle.
3. When the set temperature of the cooling circulation system is lower than 0 °C, the coolant can not be used directly. It is recommended to purchase the bath or homemade bath with the manufacturer, such as water and ethylene glycol.
4. Turn on the heating pot and cooling circulation system 30 minutes in advance.
5. Maintain a temperature difference of 50 °C between the cooling temperature and the temperature of the heating pot to ensure good cooling efficiency.
Third, do a good job of distillation
1. Do not distill more than half the volume of the evaporation flask.
2. The glass evaporation bottle should not be heated on one side. During the heating phase, the evaporation bottle is turned on to avoid bumping.
3. According to the actual size of the evaporation bottle, preset the end point.
4. Make sure the bleed valve is closed.
5. Connect and secure the evaporation flask with the clamp. After heating and cooling to the set temperature, start the vacuum pump and start the distillation.
Fourth, daily maintenance and cleaning
Heating pot: use deionized water or low-viscosity clean silicone oil, change the glass components every week: clean the glass seals every week with ethanol and apply vacuum silicone grease seals: it is recommended to check the wear of the seals every quarter (vacuum available) Value to judge)
Host: Keep the outer casing and panel dry
Cleaning: Disconnect the power when cleaning and maintaining the instrument. Use a surfactant-based cleaner or use isopropyl alcohol to clean inert stains

Monkeypox is a viral zoonosis (a virus transmitted tothose seen in the past in smallpox patients, typically-presents clinically with fever, rash and swollen lymphnodes and may lead to a range of medical complications.It is caused by the monkeypox virus which belongs totheorthopoxvirus genus of the Poxviridae family.Thereare two clades of monkeypox virus:the West Africanclade and the Congo Basin (Central African) clade.Theoname monkeypoxoriginates from the initial discovery ofthe virus in monkeys in a Danish laboratory in 1958.Thefirst human case was identified in a child in the Demo-cratic Republic of the Congo in 1970.
