For Independent Flow Control

Luer stopcocks are used to provide independent flow control of each individual port when used in conjunction with vacuum manifolds. They are made from solvent resistant high-grade Nylon, are reusable and can be readily cleaned using organic solvents such as methanol or acetone.

Specifications:

• Control flow rates during SPE
• Improve method reproducibility
• Instant isolation from vacuum reduces accidental tube drying
