Manifolds are used to support single or multiple vacuum filter holders independently off a single vacuum source. Filtrate from each branch is typically pooled, however individual fractions can be collected when using the Phase Fraction Collector assembly. PVC manifolds are lightweight and resistant to acids. Ideal for EPA Method 1664 oil and grease analysis.
Filtration assemblies are mounted on individual branches of the manifold. The standard cup accepts a #8/8B stopper and is available with a 2-way valve. The Extraction Manifold has an exterior taper 40/35 male joint which couples with a 40/35 female ground glass joint. The exterior taper is available with a 3-way valve. The PTFE valves maximize chemical resistance. The 3-way valve is used under closed conditions when venting to the atmosphere without breaking the vacuum connection is necessary. The valve vent adaptor accepts a male leur slip
PVC manifolds are NOT autoclavable and may be sanitized with ethanol or formaldehyde. The 2-way and 3-way valves are not interchangeable.
