Abbe refractometer is a bench-top refractometer that provides the highest precision of the different types of refractomerters. This is possibly the easiest method to find the refractive index of solid samples, such as glass, plastics, and polymers films. Some Abbe refractometers utilize a digital display for the measurement, to eliminate the need for discerning between small graduations.

Above ground tank removal is a process, in which the tank is pumped out, and removed. Typically above ground storage tanks are either placed inside or outside of the home. The top of the tank is cut large enough to have a field technician fit inside of the tank. The tank is then emptied and all the contents from the tank is transferred into a new tank on site, or be disposed of at a licensed waste disposal facility. The tank is then transported to an approved site to have it cut, cleaned and scrapped.
