SKU CH-DCW6-8R4Y9

Polymethylpentene filtering funnel with 140 mm diameter, 586 mL capacity and 132 mm stem, autoclavable, pack of three

  • Autoclavable polymethylpentene withstands repeated sterilisation cycles
  • 140 mm top diameter accepts large sample volumes
  • 586 mL capacity handles high-throughput filtering tasks
  • 132 mm stem reaches deep vessels without tipping
  • Colourless body allows instant visual inspection of contents

Sp Scienceware Urbanti Funnel

The Sp Scienceware Urbanti Funnel is a laboratory-grade filtering funnel moulded from polymethylpentene. It offers a 140 mm top inside diameter and a 586 mL capacity for handling large liquid volumes. The 132 mm stem with a 1.6 cm outside diameter directs flow into standard vessels. Autoclavable construction supports repeated sterilisation cycles.

Polymethylpentene material benefits

Polymethylpentene provides high thermal resistance and chemical compatibility for demanding lab environments. The colourless body allows clear visual monitoring of filtration progress. Autoclavable durability means the funnel withstands steam sterilisation without deformation. No closure is included, so users must supply their own sealing method if required.

Filtering funnel constraints

The funnel is designed specifically for gravity filtration rather than vacuum or pressure applications. Maximum outside diameter of 15.7 cm limits use with narrow-necked containers or crowded bench setups. Stem length of 132 mm may not reach the bottom of deep vessels without support. Capacity of 19.8 fl oz defines the maximum single-batch volume.

Questions about this item

Will the polymethylpentene body need replacement after repeated autoclaving?

Polymethylpentene is autoclavable and resists thermal cycling; the funnel body does not require scheduled replacement from steam sterilisation alone.

What limits continuous filtration through the 1.6 cm stem?

The 1.6 cm stem outside diameter and 132 mm stem length set the flow-rate ceiling; viscous or particle-heavy fluids will reach that hydraulic limit first.

Does the funnel deform or emit fumes when left on a hot plate all day?

Polymethylpentene withstands autoclave temperatures without deformation or off-gassing, so prolonged ambient heat from a hot plate will not alter the colourless body.
