Laboratory glass filters help New Zealand laboratories perform vacuum filtration, precipitate separation and chemical analysis with reusable sintered glass media. Source DURAN filter plates, glass filter discs and porosity filter options through our Laboratory range, with supply support from Labfriend.
Laboratory Glass Filters
Laboratory Glass Filters for New Zealand Filtration Workflows
Laboratory glass filters support repeatable filtration, separation and purification in analytical, research and quality control laboratories. This category includes DURAN filter plates and sintered glass filter discs in multiple diameters and porosity grades for vacuum filtration, precipitate retention and chemical preparation tasks.
- Product Scope: DURAN filter plates, glass filter discs and sintered glass filters for laboratory filtration.
- Supply Support: Available through Labfriend and the wider John Morris Group laboratory supply network.
- Material: Borosilicate glass 3.3 options support chemical resistance and reusable filtration performance.
- Visible Sizes: Includes 24 mm, 50 mm and 90 mm diameter filter plates and discs across the visible range.
- Porosity Range: Visible options include porosity grades 1, 2, 3 and 4 for coarse to fine filtration tasks.
Choosing Sintered Glass Filter Plates and Discs
The correct filter plate depends on the apparatus, filtration area, sample volume and particle size to be retained. Coarser filters are better suited to larger precipitates and faster flow, while finer filters are useful for analytical work with smaller particles or fine precipitates.
- Porosity Selection: Match the porosity grade to the particle size and required filtration performance.
- Diameter Selection: Choose the diameter that fits the dismountable holder, filtration head or compatible glass filtration system.
- Chemical Compatibility: Borosilicate glass options are suitable for many chemical filtration workflows, subject to the chemicals and cleaning method used onsite.
- Cleaning and Reuse: Sintered glass filters can support reusable workflows when cleaned according to laboratory procedure.
Supporting Categories for Laboratory Filtration

Frequently Asked Questions
What porosity grades are available in this laboratory glass filter range?
The visible range includes porosity grades 1, 2, 3 and 4 across different filter plate and disc sizes. The correct grade depends on the particle size, sample type and required filtration speed.
Are sintered glass filters reusable?
Yes. Sintered glass filters are designed for reusable filtration workflows when cleaned and handled correctly. Cleaning procedures should match the sample residue, chemicals used and internal laboratory quality requirements.
Can the New Zealand team help check holder compatibility?
Yes. The New Zealand team can help review the required diameter, porosity, holder type and filtration workflow before purchase. Contact 0800 651 700 for support.
