These pipettes are made from borosilicate glass in compliance with ASTM Specification E438, Type I, Class B glass requirements. They are calibrated ''to deliver'' (TD) with blow-out after free flow of liquid has ended.

Short ("shorty"), plugged-end, and sterile pipettes are ideal for use in tissue culture work and other procedures performed under a fume hood. They are packaged in color-coded, paper/plastic individual wrap.
