500
If your talking about vacuum 500 microns of Hg is lower.
Fecal specimens can be preserved by refrigeration, using preservatives such as Cary-Blair or PVA media, and by freezing. Refrigeration is suitable for short-term storage, while preservatives are used for transporting specimens to a lab. Freezing is ideal for long-term storage.
No, There should be a media.
It is generally safe to add pool chemicals while the vacuum is operating as long as you follow the manufacturer's instructions for both the pool chemicals and the vacuum. However, it may be more effective to add chemicals when the vacuum is not running to allow the chemicals to distribute evenly throughout the water before the vacuum starts circulating.
A vacuum typically requires an amp plug with a rating of 10-12 amps for standard household use. Be sure to check the manufacturer's specifications for the specific power requirements of your vacuum cleaner.
30in is 762000 microns of vacuum

vacuum is measured in pressure. To get a vacuum you need a negative pressure. that would be inches of mercury hg
I don't see how the sucking capacity of a vacuum would be measured in units of length.
Deep vacuum is usually measured in microns. This unit of measurement is commonly used in vacuum technology to indicate levels of pressure or vacuum.
A vacuum
that theres a vacuum on it
yes
I fix Coke coolers and vendors usually r134a and r 12 134a is 20 pressure and 12 14 to 16 alot easier to add with scale after pulling a vacuum
Use a vacuum pump that pulls it into a tank.
A refrigerant vacuum pump removes air and moisture from a refrigeration system, creating a vacuum. This helps prevent contaminants that can reduce the system's efficiency and cause damage. By creating a vacuum, the pump ensures that the refrigerant can flow smoothly and efficiently through the system, improving its overall performance.
When changing out a compressor or condenser, you should pull a vacuum for at least 30 minutes to an hour, depending on the system's size and the amount of moisture present. The goal is to achieve a vacuum level of 500 microns or lower to effectively remove moisture and air. Using a vacuum gauge can help ensure that the system is adequately evacuated. Always follow manufacturer guidelines for specific requirements.
