One-way stopcock valve for SPE and analytical chromatography. Constructed of temperature-, chemical-stable polypropylene and HDPE. Well perform under vacuum pressure up to 0.7 bar or 20 In.Hg. Standard female Luer-loc to male Luer-slip fittings compatible with most commonly used vacuum manifolds. ... Read more
These 1-way stopcocks are constructed of polypropylene (PP) for strength, thermal performance, and solvent resistance. They have been widely used in SPE solid phase extraction and chromatography applications that use attacking agents, such as Acetone, Acetic Acid, Isopropyl Alcohol, Ethanol, and Butyl Alcohols.
The diverter is made of high density polyethylene (HDPE), which offers excellent low friction properties and allows easy turning without the use of lubricant.
The standard female luer-lock inlet and male luer slip outlet are compatible with most commonly used vacuum manifolds.
|Polypropylene (PP) body, and natural HDPE diverter.
|Gravity, and vacuum up to 0.7 bar (10 psi or 20 In.Hg)
- Allows optimization of sample flow rates during phase separation and extraction;
- Tolerates a broader range of solvents and chemicals than the polycarbonate- or nylon-made devices;
- Easy to operate;
- Allows sterilization with disinfectants;
- Compatible to most vacuum manifolds.
