These KIMAX-51® pipettes feature a scale of permanent brown stain fused into the surface of uniform bore tubing without etching.

Pipettes are calibrated to deliver the correct volume of undiluted milk when the small amount remaining in the tip is blown out. However, the correct volume of diluted milk is delivered without blowing out. The 10 ml size is marked 'calibrated for blowout'. The 10 and 11 ml sizes are tooled for a cotton plug at the top. Color coding facilitates sorting and selection. Size 1.1 ml is designed from ASTM Specification E1043, Type IV requirements. Sizes 2.2 and 11 ml are designed from ASTM E1043, Type IV A requirements.
