clean benchProvides a clean and dust-free testing environment, protecting expensive samples from contamination and preventing dangerous samples from leaking into the surrounding environment. It has become an important laboratory equipment in research fields such as medicine, biological science, food science, and electronic science.
Usage steps:
Preparation work:
Open the glass panel and wipe the countertop with a 75% alcohol cotton ball. After closing the panel, press and hold the UV light button for 2 seconds to turn on UV sterilization for 30 minutes.
After sterilization, open the panel to the designated height and start the fan to run for 10 minutes to stabilize the internal air circulation.
Before operation, disinfect hands and items with alcohol, and wait for the alcohol to evaporate before placing them on the workbench.
Operation process:
Ignite the alcohol lamp and burn and disinfect the bottle mouth, inoculation ring, and other tools to avoid contamination.
Push the glass screen to half the height with both hands during operation to reduce external air interference, and observe through the screen.
End operation:
After use, turn off the lighting and fan, lower the glass panel, and clean the countertop with alcohol swab.
If it is an explosion-proof alcohol lamp, it needs to be covered from the side to avoid direct pressure causing explosion.
Notes:
Safety taboos:
Do not turn on both UV and fluorescent lamps simultaneously during operation to avoid UV damage.
Alcohol lamps should not be sprayed during use. If alcohol spills, a damp towel should be used to cover and extinguish the fire.
Maintenance requirements:
It is recommended to replace the high-efficiency filter every 18 months, and the initial filter can be cleaned and reused.
Avoid overloading material stacking to block air ducts, or frequent opening and closing to disrupt airflow.
