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. The exterior taper 40/35 male joint couples with a 40/35 female ground glass joint. The PTFE valves maximize chemical resistance. Both 2-way and 3-way valves are available. 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.
