What makes the best vacuum pump ? Is it one with the strongest vacuum level ? No, to make the correct selection, you need to consider several factors (laboratory application, pump type, pump speed & chemical resistance). We are glad to offer Edwards Vacuum’s range of vacuum pumps in Singapore for that.
The determining factor that should guide your choice is desired vacuum level. There are several types of vacuum: a rough or low vacuum, a high vacuum and an ultrahigh vacuum.
Vacuum type | Maximum pressure (in mbars) | Minimum pressure (in mbars) | Molecules per cm³ |
Rough vacuum | 1 | 10-3 | 1016 – 1013 |
High vacuum | 10-3 | 10-7 | 1013 – 109 |
Ultrahigh vacuum | 10-7 | 10-12 | 109 – 104 |
