SKU CH-A3ZJ-A67N1

A 1 L sterile PES filter system with 0.22 µm pores, 90 mm diameter, graduated receiver and stopper, supplied in packs of 12

  • Product typeAssortments & Kits
  • Sterile filtration removes 0.22 µm particles with PES membrane
  • One-litre upper and receiver capacity handles large-volume processing
  • Graduated markings allow quick volume checks during use
  • Autoclavable-free design saves preparation time in the lab
  • Pack of twelve units supports high-throughput workflows

Lab Filter System 0.22 µm

The Zoro Select 11L833 is a sterile filter system built around a 90 mm PES membrane with a 0.22 µm pore rating. Each unit combines a 1000 mL upper reservoir and a matching 1000 mL receiver, supplied in a pack of 12 for laboratory-scale workflows.

Suited for sterile filtration batches

This system serves technicians who need ready-to-use, graduated filter units for aqueous solutions and buffer preparation. It is not intended for buyers who require autoclavable hardware, larger-volume single-pass filtration, or non-sterile components for custom assembly.

1000 mL capacity per vessel

The 1 L upper chamber and 1 L receiver handle typical media and buffer volumes in a single step. Runs out when processing demands exceed one litre per unit or when workflows call for reusable, autoclavable funnels instead of disposable sterile sets.

Questions about this item

Does the 1000 mL upper chamber need a specific vacuum source or adapter to filter?

The unit includes a stopper, so it connects to a standard vacuum manifold or flask with a matching neck size.

Will the 90 mm PES membrane with 0.22 µm pores clog faster than larger-pore filters I have used before?

The 0.22 µm rating is finer than many general-purpose filters, so it will retain smaller particles and may load sooner with turbid samples.

How can I confirm the sterile filter units are still intact after autoclaving?

These units are not autoclavable; sterility is assured by the factory-sealed packaging, so inspect each unit for seal damage before use.
