Waltham’s PerkinElmer Inc. fell after the maker of research and science instruments reported worse-than-expected earnings on weakening product sales and cut its outlook for the year. The company reported net income of $32.2 million, or 28 cents per share, up from $22.6 million, or 19 cents, a year ago. A tax benefit helped earnings in the most recent quarter.
