Can you get these "Mullard" (CV4004) screened by APEX? If not exactly what kind of screening are done to them?

We do not test or screen the preamp tubes in house. All screening and testing would be done by the manufacturer.
How is the life span of this Mullard?

Tube life will depend on how frequently you use your equipment and total hours of operation. Unfortunately we do not have any specs on how many hours this tube will last.
Please provide a datasheet?

The manufacturer of these tubes does not provide a data sheet for these atthis time.
