For distillation of ethanol in a lab glass setup, a fractional column with good separation efficiency and a high surface area is recommended. A Vigreux column or a fractional column packed with glass beads or Raschig rings can be good choices for this application. The choice will depend on the specific requirements of the distillation process and the available equipment.
Pall Rings - Plastic PERFORMANCE CHARACTERISTICS OF THERMOPLASTIC PALL RINGSAn advance on the Raschig Ring, the Pall Ring has similar cylindrical dimensions but has two rows of punched out holes, with fingers or webs turned into the centre of the cylinder, which significantly increases the performance of the packing, in terms of throughput, efficiency and pressure drop.ApplicationGas scrubbing of Cl2, So2, No2,HCl De-aerationLiquid extractionNingbo T.C.I Co., ltdwww.rubbersealing.comis maninly manufacturer for Pall ring, Tellerette, Saddle ring, heilex ring, nutter ring, mini ring, VsP ring,liquid distributor, bubble cap tray, tower packing and tower internals.
