The Wheaton Calibra® Macropipettor has a unique, permanently calibrated series of fixed stops, each one corresponding to one volume setting. Choose capacity of 0.2 to 2.0 mL or 1 to 10 mL. An integral tip ejection system allows fast and safe macro tip removal, for simple one-handed operation. The Calibra® macropipette features a compact construction and cushioned finger and thumb rests for greater comfort and ease of pipetting. Optional cellulose paper filters may be used in conjunction with polypropylene macrotips to guard against the possibility of cross contamination. See P7350 for replacement tips. A two-year warranty covers parts and labor.
