The Macherey-Nagel PF-12Plus compact photometer is a highly advanced, optoelectronic system solution for the precise, mobile and stationary analysis of water, wastewater and environmental samples. As a portable laboratory instrument, this photometer combines state-of-the-art filter photometry with a high degree of flexibility, whether used directly at the point of interest (POI) or in a traditional laboratory setting. When monitoring critical water parameters, industrial process water flows or municipal sewage treatment works, the accurate and rapid determination of substance concentrations is the primary criterion for documenting and controlling statutory limit values in a way that is gentle on materials, comprehensive and process-reliable. The optical architecture of the PF-12Plus is based on a long-life xenon flash lamp and a precisely matched sensor system with seven integrated interference filters. This spectral configuration enables reliable coverage of all relevant wavelengths for the evaluation of Macherey-Nagel’s renowned VISOCOLOR® ECO and NANOCOLOR® tube tests. An outstanding mechatronic safety feature is the integrated nephelometric turbidity measurement (NTU-Check). This advanced control function automatically detects interfering turbidity in the sample cuvette during the measurement process and reliably alerts the user to potential measurement errors, an invaluable advantage for analytical validity in harsh field conditions. The photometer’s mechatronic system architecture is consistently designed for user ergonomics and flexibility under changing environmental conditions. Over 100 pre-programmed methods for common parameters (such as ammonium, nitrate, nitrite, COD, phosphorus or heavy metals) enable direct measurement without time-consuming calibration cycles. The splash-proof housing and intuitive menu navigation via the large, backlit graphic display allow laboratory and service staff to handle it safely. Thanks to flexible power management (optionally via batteries, rechargeable batteries, the integrated USB cable or an external power supply), uninterrupted operational readiness in the field is permanently ensured. For documentation in GLP and GMP environments, the PF-12Plus features an internal data memory for up to 1,000 measurement results, including time, date and sample ID stamps. Via the integrated USB interface, the measurement data can be transferred to the free NANOCOLOR® PC export software.

Macherey-Nagel VISOCOLOR Fish reagent case, 933101
The VISOCOLOR Fish analysis kit has been specially developed for the analysis of fishing waters. It combines reagents and accessories for the six most important water parameters in a single set: ammonium, nitrate, nitrite, phosphate, pH and total hardness. Six key parameters for water quality Anyone wishing to assess fishing waters can hardly avoid these six parameters: ammonium, nitrate and nitrite indicate nitrogen loading and thus, indirectly, the condition of the fish population; phosphate indicates nutrient inputs and algal growth; whilst pH and total hardness provide the basic data for almost any further hydrological assessment. With a single kit, the most important parameters for a fishing water assessment can be covered directly on site, without having to put together several individual tests. Use in fish farming, club waters and water monitoring Whether monitoring an aquaculture pond, carrying out a routine check by an angling or fishing club on its own waters, or taking a random sample as part of official water monitoring: the kit provides the key parameters needed to identify pollution issues at an early stage, before they endanger fish stocks. As all the tests can be carried out without an additional photometer, the kit can be used directly at the water body, without a power connection or sensitive additional equipment. Ready for immediate on-site use The kit includes a case, test kits, accessories and instructions. Results are interpreted purely visually by colour comparison. The reagents have a shelf life of 1.5 years from the date of manufacture and should be stored at 15–25 °C to ensure that results remain reliable throughout their entire service life.

Macherey-Nagel folded filter paper MN 615, qualitative, medium-speed (Ø 70–500 mm), 185 mm
Efficiency in the laboratory: Macherey-Nagel MN 615 folded filter papers Macherey-Nagel MN 615 folded filter papers are the time-saving solution for daily laboratory routines. Unlike simple filter paper circles, which have to be laboriously folded by hand (quarter-fold) before being placed in the funnel, these filters are already machine-folded (1/4-fold). This not only saves valuable working time but also offers a decisive technical advantage: the pleated structure significantly increases the effective filter surface area. The result is a faster flow rate and a reduced tendency to clog, as the precipitate is distributed more evenly. The all-rounder for qualitative analyses The MN 615 grade is the globally proven standard paper for qualitative analyses (ash content approx. 0.1 %), which primarily involve the clarification of solutions or the recovery of filtrates. Medium-speed filtration: With a filtration time of approx. 22 seconds (according to DIN 53137), this paper offers the ideal balance between speed and retention. Smooth surface: The fibres are processed to form a homogeneous structure that reliably retains particles. Retention range: Particles ranging from 4 to 12 µm (e.g. lead sulphide, calcium oxalate) are reliably filtered. Wide range of sizes We offer the MN 615 folded filter papers in a wide range of diameters: from 70 mm for small analytical funnels up to 500 mm for large-scale production batches. Please note that the diameter specified always refers to the diameter of the unfolded paper disc. Areas of application General chemistry: Clarification of salt solutions and buffers. Food analysis: Filtration of macerates, juices or extracts. Schools & Education: Time-saving preparation of school experiments. Environmental analysis: Pre-filtration of water samples. Technical data Grade: MN 615 (folded filter paper) Type: Qualitative filter paper Filtration speed: Medium-speed (approx. 22 s) Surface: Smooth Grammage: 70 g/m² Thickness: 0.16 mm Retention range: 4 – 12 µm Ash content: approx. 0.1 % Material: Cellulose (approx. 95 % alpha-cellulose) Format: folded into quarters (ready for the funnel) Packaging unit: 100 pieces per pack Scope of delivery 1 x pack of 100 Macherey-Nagel folded filter papers (grade MN 615) (The diameter corresponds to the variant you selected above.) Individual requirements & accessories Do you have the right funnel for your folded filter papers? Rule of thumb: The top edge of the folded filter paper should end approx. 1–2 cm below the rim of the funnel. A filter that is too large will protrude (risk of evaporation, tendency to creep), whilst one that is too small will not make full use of the funnel’s volume. Alternatives: If you need to filter very fine precipitates (e.g. barium sulphate), we recommend the denser grade MN 619. For very coarse, bulky precipitates, opt for grade MN 617. Do you require large quantities for industrial use or special sizes? Please contact our procurement service.

Macherey-Nagel folded filter paper MN 616 md, qualitative, 4–7 µm (Ø 55–500 mm), 150 mm
For finer precipitates: Macherey-Nagel MN 616 md folded filter papers Macherey-Nagel MN 616 md folded filter papers 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 qualitative filter papers that are machine-folded (1/4-fold) so that they can be inserted into the funnel straight away. 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 speed: At approximately 55 seconds (according to DIN 53137), this paper filters significantly more slowly than the standard MN 615 type. This reduced flow rate is necessary to reliably retain finer particles. Retention capacity: The pore size range is 4 to 7 µm. This means 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 folded filter papers Despite the finer pore structure, you benefit from the pleated geometry. The large surface area prevents the filter from becoming clogged quickly, which is often a problem with flat filter paper circles 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-funnel applications right up to the 500 mm large format for technical applications. Areas of application Analysis: 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. Technical data Grade: MN 616 md (folded filter paper) Type: qualitative filter paper Filtration speed: Medium-speed to slow (approx. 55 s) Surface: Smooth Grammage: 85 g/m² Thickness: 0.17 mm Retention range: 4–7 µm (fine particles) Ash content: approx. 0.1 % Material: Cellulose Format: folded into quarters Packaging unit: 100 pieces per pack Scope of delivery 1 x pack of 100 Macherey-Nagel folded filter papers (grade MN 616 md) (The diameter corresponds to the variant you selected above.) Individual 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.

Macherey-Nagel folded filter papers, grade MN 617, qualitative, fast-filtering (Ø 55–500 mm), 90 mm
Macherey-Nagel MN 617 folded filter papers represent a system solution optimised in terms of materials science and highly efficient in terms of geometry, designed for rapid clarification, coarse particle separation and general sample preparation in day-to-day laboratory work. Available in an extremely wide range of diameters, from 55 mm for small-scale analytical batches up to large-area 500 mm filters for high-volume separation processes, this filter series caters for every scale of modern laboratory processes. For routine filtration in food analysis, environmental chemistry or industrial quality control, the structural purity and fibre stability of the filter paper are the primary criteria for clarifying media in a way that is gentle on the material, contamination-free and process-reliable. Maximum filtration speed thanks to pre-pleated geometry The design and fluid-mechanical foundation of this series lies in its ready-to-use pleated structure. Unlike traditional filter paper circles, which must first be laboriously folded twice before being inserted into the funnel, the pre-formed pleat pattern multiplies the effective filtration surface area. This leads to a drastic reduction in filtration times during daily high-throughput operation. With a standardised filtration speed of approx. 9 seconds according to the manufacturer’s specification, the MN 617 grade enables an extremely rapid liquid throughput. Flow resistance is minimised, thereby gently reducing unwanted blocking effects in viscous or particle-rich sample flows. High wet tear strength and the purest raw material base From a materials science perspective, the MN 617 grade is based on refined pulp and high-quality linters, which are processed entirely free from chemical binders or additives. The smooth surface structure ensures a homogeneous non-woven fabric that exhibits excellent inherent mechanical stability. Thanks to optimised fibre entanglement, the filters possess remarkable wet tear strength. They withstand the fluid-mechanical pressure during funnel filtration without damage and do not tend to release fibres into the filtrate. With a typical ash content of approximately 0.1 %, the paper is perfectly suited to qualitative analytical procedures where ash-free incineration is not strictly required. Cost-effective routine use The infrastructural validity of the MN 617 folded filter papers is demonstrated by their reliability in recurring routine tasks. As the filters are supplied pre-pleated and ready for use, laboratory staff save valuable working time whilst simultaneously minimising the risk of contamination from manual folding. For laboratory managers and quality management officers in regulated B2B environments, Macherey-Nagel’s range provides a basis for recurring test processes in GLP environments. Technical details Material science & filter structure Filter type: qualitative filter paper / folded filter paper (pre-configured and ready for use) Grade / Quality level: MN 617 Material basis: Refined alpha-cellulose and the purest linters Binder status: 100 % binder-free (free from chemical additives) Surface structure: Smooth Filtration properties: Fast filtration (open-pored structure for coarse precipitates) Filtration speed: approx. 9 seconds (standardised according to manufacturer’s specifications) Ash content: approx. 0.1 % (qualitative classification) Physical properties & dimensions Grammage: approx. 85 grams per square metre (85 g/m²) Filter thickness: approx. 0.22 mm (millimetres) Available diameter range: 55 mm to 500 mm Diameter variants in the range: 55, 70, 90, 110, 125, 150, 185, 240, 270, 320, 385, 400, 450, 500 mm Resistance & compliance Chemical resistance: Inert to mild acids, alkalis and a wide range of organic solvents Wet tear strength: High (structurally stable under liquid load) Quality management: Supports standardised, reproducible routine filtration processes in GLP environments Scope of delivery 1 x pack of Macherey-Nagel folded filter papers, grade MN 617, qualitative and fast-filtering (standard contents: 100 pieces per box) in the diameter selected by the customer (55 mm to 500 mm).

Macherey-Nagel VISOCOLOR School reagent case, 933100
The VISOCOLOR SCHOOL analysis kit brings hands-on water analysis straight into the classroom: all the reagents included correspond to the GUV rule for handling hazardous substances in the classroom (GUV-SR 2004). Pupils can therefore carry out the experiments themselves without teachers having to intervene at every step. A safe introduction to water analysis for the classroom Whether in chemistry, biology or geography lessons: water analysis is an integral part of many curricula when it comes to topics such as water quality, nutrient inputs or ecosystems. The VISOCOLOR SCHOOL analysis kit makes such experiments suitable for everyday use, for example when analysing water samples from a nearby stream, pond or lake as part of a field trip, or directly in the classroom using samples brought in by the pupils. As the reagents conform to GUV-SR 2004, even younger pupils can carry out the tests and evaluate colour comparisons themselves under supervision. Ammonium and pH: two parameters of high educational value The kit covers the determination of ammonium (graduation 0 / 0.2 / 0.5 / 1 / 3 mg/L NH₄⁺) and pH (graduation 4.0 / 5.0 / 6.0 / 7.0 / 8.0 / 9.0). Both parameters are well suited to teaching pupils fundamental concepts: ammonium as a classic indicator of organic pollution and nutrient inputs into water bodies, and pH as a key parameter for virtually any chemical and biological analysis of water. The kit includes a case, test kits, accessories and instructions, ready to use for the next lesson. Ready for immediate use without a photometer Analysis is carried out purely visually by colour comparison, without the need for an additional photometer. This significantly lowers the barrier to entry for schools and other educational institutions with limited equipment and enables several groups to work simultaneously, each group with its own test kit, without a single measuring device becoming a bottleneck. Cost-effective refills Once the supplies have run out, there’s no need to buy a whole new kit: an affordable refill pack is available if required.

Macherey-Nagel glass fibre filter circles MN 85/90 BF, binder-free, 0.5 µm (Ø 25–270 mm), 90 mm
Determining suspended solids in a water sample means filtering, drying and weighing. The Macherey-Nagel MN 85/90 BF glass fibre filter circles are intended for this. They consist of borosilicate glass microfibres without binder and, according to the data sheet, are suitable for the determination of suspended solids according to DIN EN 872:2005. The average retention capacity is 0.5 µm and the maximum temperature is 500 °C.Binder-free glass fibre filter circles for oven and balanceIn gravimetric methods, the filter is weighed before and after filtration. Macherey-Nagel explicitly names weighing by difference as an application of this type. Without a binder, the filter has no organic component that could lose mass at higher temperatures. The thickness is 0.51 mm with a grammage of 90 g/m², and the filtration speed is 15 s.Thermally and chemically robustMacherey-Nagel describes binder-free glass microfibre filters as thermally and chemically resistant. They are therefore also used for dust filtration in air and hot exhaust gases. The manufacturer describes its glass fibre filter papers made of 100 % borosilicate glass as suitable for aggressive media such as strong acids and bases.MN 85/90 BF or MN 85/90 with binderRetention capacity (0.5 µm) and grammage (90 g/m²) are the same for both types. The version with binder is thicker at 0.6 mm and, according to Macherey-Nagel, mechanically more stable, but it withstands only 200 °C. If you work in an oven or filter aggressive solutions, use the BF. If you filter in general and do not exceed 200 °C, you can stay with the MN 85/90 with binder.Typical applicationsDetermination of suspended solids in water and wastewater according to DIN EN 872:2005Gravimetric analyses with weighing by differenceFiltration of aggressive solutions where an organic binder would interfereDust filtration in air and hot exhaust gasesAvailable diameters13 diameters from 25 to 270 mm are available.

Macherey-Nagel filter paper circles MN 619 qualitative, slow-filtering, smooth (Ø 55–500 mm), 150 mm
The Macherey-Nagel MN 619 filter paper circles represent a structurally optimised and process-proven system solution for qualitative filtration in everyday laboratory work. Available in a wide range of diameters, from 55 mm for compact standard funnels up to 500 mm for high-volume separation processes, this filter series caters for every scale in chemistry, the pharmaceutical industry, environmental analysis and industrial quality control. Wherever fine-particle suspensions need to be clarified or demanding samples prepared, this slow-filtration quality enables gentle, particle-free and process-reliable working. Maximum particle retention thanks to a dense fibre structure The technological foundation of the MN 619 filter paper circles is based on refined cellulose and linter fibres, which are processed into a homogeneous, close-meshed structure. The slow filtration speed of around 100 seconds (according to the manufacturer’s specifications), from which the filter takes its name, results from the high density of the pore structure. This geometric structure ensures that even fine crystalline precipitates and microparticles are reliably retained on the filter surface. The risk of a transient particle flow through the filter medium is thus effectively minimised, which reliably safeguards the validity of subsequent qualitative analyses. Smooth surface geometry for residue-free separation From a materials science perspective, the completely smooth surface of the filter paper circle offers significant functional advantages in sample preparation. Unlike creped variants, fine precipitates on the smooth structure do not tend to become lodged in fibre recesses. This noticeably facilitates the subsequent mechanical removal or washing out of the filter cake. Furthermore, the material is characterised by high purity and a low ash content for qualitative filter papers, thereby gently preventing unwanted chemical interactions with the sample medium or solvent extractions. High wet strength for reproducible laboratory processes Despite being based on pure cellulose without synthetic stabilisers, the MN 619 filter paper circles exhibit remarkable inherent mechanical stability when wet. The three-dimensional depth structure remains completely dimensionally stable even under the hydrostatic pressure of a fully filled funnel. For laboratory managers and quality management personnel in regulated environments, Macherey-Nagel offers, with this standardised fibre grade, a documentation basis for recurring routine filtrations in GLP environments.

Macherey-Nagel MN 615 filter paper circle, qualitative, medium-speed (Ø 25–500 mm), 500 mm
The all-rounder for the laboratory: Macherey-Nagel MN 615 filter paper circles Macherey-Nagel MN 615 filter paper circles are an indispensable part of the basic equipment for chemical analysis and industrial quality assurance. These are qualitative filter papers designed for general separation tasks where the filter residue does not need to be determined gravimetrically (no ash-free ignition required). This product range is characterised by its versatility: it is available in numerous diameters ranging from 25 mm to 500 mm, thus covering every funnel size, from the smallest micro-funnel right through to large industrial filtration units. Features: The happy medium The MN 615 grade is the standard for routine filtration. It offers the ideal balance between time savings and particle retention: Filtration speed: Classified as medium-speed filtration (approx. 22 seconds according to DIN 53137), the paper enables rapid processing without clogging. Surface: The filters are smooth. This makes it considerably easier to scrape off or recover precipitates from the filter cake. Retention capacity: With a pore size range of approx. 4 to 12 µm, medium-fine to coarse precipitates (such as sulphides, lead chromate or calcium oxalate) are reliably retained. Quality and purity Macherey-Nagel uses high-quality raw materials for these filters. They consist of approximately 95 % alpha-cellulose, which contributes to high chemical stability. The ash content is approximately 0.1 %. This means the filters are largely chemically inert. Areas of application Routine laboratory work: Clarification of buffer solutions and reagents. Education: Standard filters for schools and universities (qualitative analysis). Food industry: Filtration of extracts and juices. Electroplating & metalworking: Bath maintenance and analysis. Select the suitable diameter Simply select the diameter that fits your funnel from the menu above. As a rule of thumb: when inserted, the filter should not protrude beyond the rim of the funnel, but should end approximately 1–2 cm below the rim. Technical data Grade: MN 615 Type: Qualitative filter paper, filter paper circles Filtration speed: Medium-speed (approx. 22 s) Surface: Smooth Grammage: 70 g/m² Thickness: 0.16 mm Retention range: 4 – 12 µm Ash content: approx. 0.1 % Material: Cellulose Packaging unit: 100 pieces per pack Scope of delivery 1 x pack of 100 Macherey-Nagel filter paper circles (grade MN 615) (The diameter corresponds to the variant you selected above.) Individual requirements & accessories Filter paper is only as good as the accessories used with it. To ensure your filtration process runs smoothly, you’ll need the right funnel. Suitable funnels: Whether made of glass or robust plastic (PP/TPX), make sure that the filter diameter you have chosen matches the funnel size (the filter should end approx. 1–2 cm below the rim). Other pleat configurations: Do you require faster filtration whilst maintaining the same pore size? We also offer this grade as folded filter papers (increased surface area). Quantitative analyses: If you need to ash the residue (gravimetry), you will require ash-free filters (e.g. MN 640). Can’t find the right size, or do you need large quantities for industrial applications? We can source any speciality filter for you. Please contact our procurement service.
Macherey-Nagel MN 85/90 round glass fibre filter with binder, 0.5 µm (Ø 25–320 mm), 45 mm
The Macherey-Nagel MN 85/90 glass fibre filter circles are intended for general laboratory filtration. They consist of borosilicate glass microfibres with an organic binder, have a smooth, white surface and a thickness of 0.6 mm. The average retention capacity is 0.5 µm and the filtration speed is 15 s. One pack contains 100 filters, and 13 diameters from 25 to 320 mm are available.Glass fibre filter circles with and without binderThe organic binder holds the glass fibres together. According to Macherey-Nagel, this gives the filter comparatively high mechanical stability. The binder-free counterpart MN 85/90 BF has the same retention capacity of 0.5 µm and the same grammage of 90 g/m². At 0.51 mm it is slightly thinner than the MN 85/90 at 0.6 mm, and it withstands 500 °C, whereas the MN 85/90 withstands only 200 °C.If you only filter off the residue and dry it at up to 200 °C, the filter with binder is sufficient. For higher temperatures and for aggressive solutions, the BF version is the better choice because it contains no organic component.MN 85/90 or MN 85/70The MN 85/70 is also a glass fibre filter with an organic binder and a filtration speed of 15 s. At 0.6 µm it retains more coarsely, weighs 73 g/m² and is 0.42 mm thick. The MN 85/90 is therefore finer, heavier and thicker. If the finer retention of 0.5 µm matters, the MN 85/90 is the suitable type.Typical applicationsClarification filtration of solutions, extracts and digests before analysisSeparation of precipitates and solids in vacuum filtrationPrefiltration of samples that would quickly clog a membrane filterRoutine filtration in the laboratory up to 200 °CAvailable diametersThe diameter depends on the funnel or filter holder.

Macherey-Nagel MN 85/70 glass fibre filter circles, with binder, 0.6 µm (Ø 25–320 mm), 320 mm
The Macherey-Nagel MN 85/70 glass fibre filter circles are the thinner and lighter alternative to the MN 85/90. Both are glass fibre filters with an organic binder for general filtration. The MN 85/70 has a thickness of 0.42 mm and weighs 73 g/m², and its average retention capacity is 0.6 µm. As with the MN 85/90, the filtration speed is 15 s and the maximum temperature is 200 °C.MN 85/70 glass fibre filter circles compared with MN 85/90The data sheet values of the two types at a glance:ValueMN 85/70MN 85/90Average retention capacity0.6 µm0.5 µmGrammage73 g/m²90 g/m²Thickness0.42 mm0.6 mmFiltration speed15 s15 sMaximum temperature200 °C200 °CThe MN 85/70 therefore retains somewhat more coarsely, but is thinner and lighter. According to the data sheet, it is not faster; both types are at 15 s. If you need a retention capacity of 0.5 µm, use the MN 85/90. If 0.6 µm is sufficient, the MN 85/70 is the slimmer type.More diameters, including 47, 50 and 100 mmWith 16 diameters from 25 to 320 mm, the choice is larger than with the MN 85/90, which has 13. In addition, 47, 50 and 100 mm are available here. The diameter depends on the funnel or filter holder.Typical applicationsThe MN 85/70 is used for clarification filtration of solutions and extracts, for separating precipitates in vacuum filtration and for prefiltration of samples that would quickly clog a membrane filter. According to Macherey-Nagel, the organic binder gives the filter comparatively high mechanical stability.

Macherey-Nagel glass fibre filter circles MN GF-1, binder-free, 0.7 µm (Ø 25–270 mm), 90 mm
The Macherey-Nagel MN GF-1 glass fibre filter circles filter quickly while retaining particles from 0.7 µm. According to the data sheet, the filtration speed is 12 s. This is shorter than for the MN 85/90 and MN 85/70 at 15 s each and for the MN GF-3 at 25 s. The filter consists of borosilicate glass microfibres without binder, is 0.28 mm thick and weighs 52 g/m².Glass fibre filter circles with short filtration timeMacherey-Nagel describes the GF-1 as a glass fibre filter with fast filtration and very good retention for highly efficient laboratory filtration and air sampling. The average retention capacity of 0.7 µm is above that of the MN GF-3 and MN 85/70 at 0.6 µm each and of the MN 85/90 at 0.5 µm. If you mainly want to save time and 0.7 µm is sufficient, the GF-1 is suitable. For a finer filtrate, the MN GF-3 is an option.Up to 500 °C without binderWithout a binder, the GF-1 withstands up to 500 °C according to the data sheet. The types with binder, MN 85/90 and MN 85/70, are rated up to 200 °C and, according to Macherey-Nagel, have comparatively high mechanical stability. The GF-1 is the type to choose when speed and temperature matter more than this additional strength.Typical applicationsLaboratory filtration with high throughput where a retention capacity of 0.7 µm is sufficientAir sampling in which particles are collected on the filterFiltration of samples with a high solids content, for which Macherey-Nagel attributes a good loading capacity to the GF-1Gravimetric determinations with drying or ignition in an oven at up to 500 °CAvailable diameters13 diameters from 25 to 270 mm are available, with 100 filters per pack.

Macherey-Nagel filter paper circle MN 617, qualitative, fast (9 s), smooth (Ø 55–500 mm), 70 mm
Rapid filtration for routine qualitative analysis In chemical, biological and industrial laboratory practice, the time-saving separation of coarse solids from liquid media is an essential process step. In contrast to quantitative analyses, where the filter paper must be ashed, qualitative filtration focuses on the rapid and efficient clarification of sample solutions. The Macherey-Nagel MN 617 filter paper circles have been developed specifically to meet these requirements. Featuring a smooth, soft surface, these cellulose filters represent the ideal laboratory standard for the rapid routine purification of biological extracts, chemical buffers or large-volume aqueous solutions. With an extremely wide range of diameters, from 55 to 500 millimetres, the system can be integrated precisely and without the need for a bypass into virtually any laboratory or industrial funnel. Material specifications: High-purity cellulose matrix The analytical quality of filter paper is primarily defined by its fibre structure. The MN 617 grade is manufactured from strictly selected raw materials that ensure optimum physical integrity. The paper consists of the finest cotton linters (extremely absorbent, short fibre strands from cotton seeds), combined with chemically refined pulp from coniferous and deciduous wood. This high-purity fibre blend gives a high alpha-cellulose content of approximately 95 %. Although this is a purely qualitative filter paper, for which the ash content is usually of secondary importance in terms of process technology, this value is remarkably low at approximately 0.1 %. A precisely calibrated grammage of 85 g/m² and a constant material thickness of 0.22 mm give the filter a slight wet strength, which is entirely sufficient for all standard funnel filtration processes without the need for significant additional overpressure or a strong vacuum. Filtration kinetics: Rapid flow rate with defined particle retention The outstanding process-related property of the MN 617 is its extremely high filtration speed. In the standardised Herzberg test, the paper achieves an excellent value of just 9 seconds (the time required for 10 ml of water to pass through unimpeded). This classification as a ‘fast’ filtering paper results from a physically open, more widely spaced fibre matrix. The filter is therefore well suited for the rapid separation of coarse, bulky or extremely flocculent particles. The retention capacity lies within the defined range of 7 to 12 micrometres (µm). Typical applications in routine laboratory work include the retention of coarse crystalline precipitates, the separation of insoluble impurities in preparation for sensitive optical analysis (such as photometry or spectroscopy), or the filtration of extremely viscous, gelatinous residues which would immediately render finer and more tightly meshed filter papers unusable due to clogging. Technical details Product type: qualitative filter paper for routine analysis Grade: Macherey-Nagel MN 617 Format: Filter paper circle (pre-cut for easy folding) Available diameters: 55, 70, 90, 110, 125, 150, 185, 240, 270, 320, 385, 400, 450, 500 mm Base material: High-purity cellulose blend (cotton linter and refined pulp) Alpha-cellulose content: approx. 95 % Filtration speed (classification): Fast Filtration time (Herzberg): 9 seconds Particle retention capacity: 7–12 µm Grammage: 85 g/m² (for a stable structure) Thickness: 0.22 mm Surface texture: Smooth and soft Wet strength: Low (ideal for unpressurised gravity filtration) Ash content: approx. 0.1 % Colour: White Scope of delivery 1 x folding box containing 100 Macherey-Nagel MN 617 filter paper circles (Please select the variant with the diameter that fits your funnel: Ø 55 to 500 mm) Individual requirements & accessories Filter paper only achieves its full hydrodynamic filtration performance when used in perfect conjunction with the correct analysis funnel. Ensure that the 60° angle of the glass funnel matches the fold of your filter paper exactly to prevent air pockets. If you need to filter extremely fine precipitates (such as barium sulphate) rather than coarse particles, we strongly advise against using this fast-flowing paper and recommend switching to the MN 619 eh (slow, 140 s) or MN 619 de (very slow, 195 s) variants.
