A measuring tape, a landing area made of sand.

For example in the most strong cosmic vacuum are millions of neutrinos. And in an installation increasing the temperature and the power of the pump the degassing continue down to the minimal resolution of the measuring instrument but this is not the "ideal" vacuum - it is the minimum possible in some conditions. The absolute vacuum is impossible - in nature or laboratory.
A balance is the best tool for measuring mass.

how would you find the density of an unknown liquid if you have all of the equipment of the laboratory equipment you need?

A measuring tape.
It is dangerous to play football in a science laboratory as you may knock over expensive equipment.
If you mean science equipment, then you'd see various types of glassware, apparatus for holding glassware, heating equipment such as a bunsen burner, safety equipment like fire extinguishers and goggles, measuring instruments like thermometers and all sorts of specialist stuff depending on the use of the laboratory. A teaching laboratory might have demonstration equipment like a ripple tank. If you mean everyday tools such as you'd find in your toolbox, I'd expect screwdrivers in different sizes, a drill, a hammer, pliers, wire strippers and possibly an adjustable wrench.
A dose meter or perhaps a Geiger counter.
Then constantly, experiments and tests would produce "un-accurate" answers, because of the other foreign microbes on their equipment.

Depends on the required accuracy. > Find your average pace, and pace it out. Use a measuring wheel. Use a tape measure. Use laser measuring equipment.
For measuring the mass (solids) of a substance you would need to use a balance. Measuring volume (liquids) a volumetric flask is required.
