Product information "Macherey-Nagel pleated filter MN 616 md, high quality, 4–7 µm (Ø 55–500 mm) – 125 mm"
For finer particulate matter: Macherey-Nagel MN 616 md pleated filter
Macherey-Nagel MN 616 md pleated filters are the right choice when standard filters (such as the MN 615) reach their limits. In this quality grade, the abbreviation ‘md’ stands for a slightly higher density and improved retention capacity. These are high-quality filter papers that are machine-pleated (1/4-fold) so that they can be inserted directly into the funnel.
The difference: medium-speed to slow
In everyday laboratory work, it often happens that fine-grained precipitates pass through a standard filter (leaving the filtrate cloudy). This is where the MN 616 md comes into its own:
- Filtration rate: At approximately 55 seconds (in accordance with DIN 53137), this paper filters about half as fast as the standard MN 615 type. This reduced flow rate is necessary to reliably trap finer particles.
- Retention capacity: The pore size range is 4 to 7 µm. This ensures that fine precipitates such as barium sulphate (cold-precipitated), tin oxide or sugar solutions are reliably clarified.
- Surface: The filters are smooth, which enables good recovery of the precipitate.
Advantages of pleated filters
Despite the finer pore structure, you benefit from the pleated geometry. The large surface area prevents rapid clogging of the filter, which is often a problem with flat circular filters of the same density. You obtain a clear filtrate within a reasonable time.
Quality and purity
The MN 616 md grade is made from high-quality cellulose with a very high proportion of alpha-cellulose. The ash content is < 0.1%, which makes the paper virtually chemically inert. It is perfectly suited to qualitative analyses in chemistry, biology and food monitoring.
Available sizes
We offer this speciality paper in a comprehensive range, from small 55 mm filters for micro-funnels right up to 500 mm large-format filters for technical applications.
Areas of application
- Analytical: Filtration of fine precipitates (e.g. calcium oxalate, magnesium ammonium phosphate).
- Beverage industry: Clarification of wine, beer or juices in cases of fine turbidity.
- Electroplating: Bath maintenance for fine suspended solids.
- Environment: Soil analysis and water treatment.

Custom requirements & accessories
When should you choose MN 616 md instead of MN 615?
- Opt for MN 616 md if your filtrate is still cloudy when using MN 615.
- Switch back to MN 615 if filtration with MN 616 md takes too long and the filtrate is already clear enough.
Do you need funnels, stand fittings or beakers to collect the filtrate? We can fully equip your workstation. Please contact our procurement service.
