Boiling dryer operating conditions
The boiling dryer is suitable for the drying of finished products and intermediates in the pharmaceutical, food, light industry and chemical industries. The working principle of natural air is drawn by the fan, passing through the purification cabinet and the heater to form a high-speed airflow in the small hole of the material bed. The material is boiled, and the moisture in the material is rapidly evaporated during the gas-solid two-phase large-area contact process, thereby achieving drying. After the air is purified by heating, the air is blown from the lower part by the induced draft fan and passes through the hole mesh plate of the hopper. In the working chamber, fluidization is formed by stirring and negative pressure, and the water is quickly evaporated and then taken away with the exhaust gas, and the material is quickly dried.
1. Closed negative pressure operation, air flow through filtration. Easy to operate, easy to clean, is the ideal equipment to meet the requirements of "GMP".
2. The drying speed is fast and the temperature is uniform. The drying time of each batch is 20-30 minutes.
3. The hopper is set to agitate to avoid the formation of channeling when the wet materials are agglomerated and dried.
4. The boiling dryer adopts tipping and unloading, which is convenient and rapid, and can also design automatic feeding and discharging system according to requirements.
5. The fluidized bed has a circular structure to avoid dead ends.
6. This machine can also be designed and manufactured automatically according to requirements.

Virus Specimen Collection Tube

Inspection principle:
It can perform protein denaturation on fresh clinical virus samples to inactivate the virus, prevent secondary transmission of infection, and ensure the safety of transportation and testing personnel.
♣.Structural composition: Combination of cotton swab and transport medium (VTM).
♣. Product requirements:
The product should be airtight, avoid high temperature, avoid direct sunlight storage. It should be used in a clean, hygienic, pollution-free, and temperature-friendly environment.
♣, Storage conditions and validity period:
â‘ , the product should be stored in a clean, dry and ventilated environment,
②, the temperature is 5℃-35℃;
â‘¢, relative humidity <85%RH;
â‘£, product shelf life: 12 months.
♣. How to use
â‘  Before sampling, mark relevant information on the label of the sampling tube.
â‘¡. Sampling with the corresponding cotton swabs.
â‘¢ After the collection is completed, quickly put the cotton swab into the collection tube, break the part higher than the sampling tube, and tighten the tube cover.
â‘£. For the specific sampling method, please refer to the following:
a) Nasal swab Gently insert the sampling head into the nasal cavity, stop for a while and then slowly rotate to exit, immerse the collected specimen in the Xiangxiang solution, break the excess part and discard it, and tighten the sampling tube cover.
b) Pharyngeal swab: Wipe bilateral pharyngeal tonsils and posterior pharyngeal wall with the sampling head, immerse the collected specimen in the sampling solution, break off the excess part and discard it, and tighten the cap of the sampling tube.
c), Mycoplasma Chlamydia, Ureaplasma specimen collection
Male: Insert the sampling head into the urethra about 2cm and rotate, stay for a while and then exit, and immerse the collected specimen in the sampling solution.
Female: Wipe the mucus of the cervical orifice, insert the sampling tip into the cervical canal for 1-2 cm for sampling, immerse the collected specimen in the sampling solution, break off the excess part and discard it, and tighten the cap of the sampling tube.
♣. Precautions
1. After the virus is collected, the disposable sampling swab should be completely inserted into the preservation solution, so that the virus can be retained to the greatest extent possible.
â‘¡ The collected specimens must be sent for inspection in time.
â‘¢. It is forbidden to use products with damaged packaging and expired validity period to prevent pollution.
This single-use Virus Sampling Tube is used for in vitro diagnosis. It cannot be used for human or animal oral or external use. If swallowed, it may cause serious events; it is irritating to eyes and skin. If it is not splashed into the eyes, rinse with water.
