About this material

What it is

Sterilising-grade polyethersulfone membrane filters in a 25 mm Luer-lock housing, individually blister-sealed. Three units from every carton are bubble-point tested and the result is recorded on a carton certificate — the same archive treatment given to compound lots, because a filter that fails integrity invalidates whatever passed through it.

Laboratory handling

Storage and material handling

  1. 01Bubble-point integrity is verified on three units per carton. The result is on the carton certificate.
  2. 02Discard any unit whose blister seal is compromised.
  3. 03Polyethersulfone membrane — check solvent compatibility against your mobile phase before use.
  4. 04Dispose of used filters as contaminated consumables under your institution's waste procedure.

Laboratory storage and material handling only. No dose, concentration, route, frequency or administration guidance is provided for this or any other item, for humans or animals.

Documentation

Even the consumables carry a certificate

Did not expect a carton of filters to arrive with a bubble-point record. It meant that when a separation looked wrong I could rule the filter out in about a minute instead of an afternoon.
