Cole-Parmer Dust-It, Handheld Air Blower

主要特点

Bulb duster blows away dust, lint, and dirt. It provides gentle-pressure pinpoint jets of air exactly where desired. Varying the amount of compression provides for controlled delivery.
One-way inlet valve at the top stops air from being drawn through the tip. Nonconductive plastic sleeve-tip prevents scratches and allows you to easily clean optical lenses, slides, circuit boards, and cuvets. Size is 2-1/4"x 5" and weighs 2 ounces.
