Fraction Recovery System

Two types of systems are available: one with a flatbottomed cap, and those with hollow-cone caps. Using the flat-bottomed cap, sample is removed through a puncture hole in the bottom of the tube. This cap fits any tube diameter and must be used to fractionate Quick- Seal tubes. The four hollow-cone cap systems are used for sample recovery from tubes that cannot be punctured or for recovery from the tops or bottoms of puncturable tubes. Each hollow-cone system is for a single tube diameter. System Part Numbers 342023 Fraction Recovery System with Hollow-cone Cap for 1 ⁄ 2 -in.
