The phrase "a mild vacuum" is correct and usable in written English.
It can be used to describe a vacuum that is not very strong or intense, often in scientific or technical contexts.
Example: "The experiment required a mild vacuum to ensure that the reactions occurred without interference from atmospheric pressure."
Alternatives: "a light vacuum" or "a gentle vacuum".
A mild vacuum pressure further increases blood flow to the hand.
In a case study, we demonstrate the applicability of our technology through successful localization of a solution of rhodamine on a polydimethylsiloxane (PDMS) substrate and production of sub-millimetre-sized spots via application of a mild vacuum level of less than -10 kPa.
The reaction mixture was placed in a mild vacuum for 10 min, and then incubated overnight at 37°C.
The oil and n-hexane solution was then evaporated under a mild vacuum with a rotary evaporator.
Two microliters of cell supernatant or cell lysate protein was applied to ABS-Tween moImmobilon-Ny+membraneMillipore(Millipore, Billerica, MA, USA) under a mild vacuum in dot-blot apparatus (Minifold, Sigma-Aldrich).
The membranes were washed twice in 200 ml of ABS-Tween for 30 min each time under a mild vacuum, blocked in TBS-skimmed-milk solution for 1 h at room temperature and incubated in TTM-primary antibody solution overnight at 4 °C.
Briefly, 600 µl of 10% PLLA/THF solution was cast under mild vacuum into an assembled sugar template by bound sugar spheres approximately 250 425 µm in diameter.
Microcoleus suspensions (5 ml, 0.25 O.D(678 nm) were filtered through nitrocellulose filters (0.4 µm) by mild vacuum suction to form an equally distributed artificial film.
The remaining acetonitrile was evaporated under mild vacuum conditions for 30 min using a rotary evaporator.
After extraction, the cakes were filtered with mild vacuum and dried at 80°C for 8 h.
The mild vacuum impregnation protocol, which was designed on the basis of measured apparent porosity, did not achieve full impregnation of the tissue.
