Brand: Microsidd
Product: Qualitative Filter Paper – Round Circles
Category: Laboratory Consumables / Filtration Supplies
Size: 12.5 cm (125 mm / 4.92 inches) Diameter
Pack Size: 100 Circles
Microsidd Qualitative Filter Paper is a laboratory filtration paper supplied as pre-cut round circles measuring 12.5 cm (125 mm / approximately 4.92 inches) in diameter.
Each pack contains 100 filter paper circles, making it a convenient laboratory consumable for routine filtration, sample preparation and qualitative analytical procedures.
The circular pre-cut format eliminates the need to manually cut filter-paper sheets before routine use and is particularly convenient for use with appropriately sized laboratory filter funnels and filtration setups.
The existing Microsidd listing identifies this product specifically as a qualitative filter paper intended for laboratory applications.
Brand: Microsidd
Product: Qualitative Filter Paper
Shape: Round / Circular
Diameter: 12.5 cm / 125 mm / 4.92 inches
Pack Size: 100 Circles
Primary Application: Laboratory filtration and qualitative analysis
Qualitative filter paper is a porous laboratory paper used primarily for routine filtration and qualitative analytical procedures.
During filtration, the paper is normally folded or positioned inside a suitable laboratory funnel. A liquid containing suspended solid material is passed through the filter paper. The liquid that passes through is collected as the filtrate, while suitable suspended particles are retained by the paper.
The actual filtration performance depends on factors including the paper's grade, pore/retention characteristics, sample properties and filtration procedure.
For applications requiring a specific particle-retention rating, flow rate, ash content or quantitative gravimetric analysis, laboratories should use a filter-paper grade whose relevant technical specification has been validated for that procedure.
Microsidd 12.5 cm Filter Paper can be considered for routine applications such as:
The existing Microsidd page also identifies filtration, chromatography, moisture testing, electrochemical applications and sample collection among general filter-paper applications.
Each filter is supplied as a ready-to-use 12.5 cm round circle, reducing the need to cut circles manually from filter-paper sheets.
The 100-circle laboratory pack is convenient for laboratories, educational institutions and other users performing repeated filtration procedures.
Suitable for routine filtration and qualitative laboratory procedures where a compatible general-purpose filter paper is required.
The circular shape makes the filter paper convenient to fold and position inside an appropriately sized laboratory funnel.
A fresh filter circle can be used for each applicable procedure, helping laboratories maintain appropriate sample-handling practices.
The flat circular papers are easy to store alongside funnels, glassware and other routine laboratory consumables.

Select a funnel appropriate for the filter-paper diameter and intended procedure.
Fold the circular filter paper according to the filtration technique being used and position it securely inside the funnel. Where the procedure requires it, wet the paper appropriately so it seats against the funnel.
Place the funnel over the receiving vessel and carefully introduce the sample.
Allow the liquid to pass through the paper without overfilling the filter.
Discard the used filter paper according to your laboratory's waste-handling procedures and the nature of the material that has contacted it.
This product creates an excellent internal-linking opportunity.
Microsidd also currently sells the Borosil Glass Funnel 6220, including a 125 mm variant, and specifically identifies filter-paper filtration as one of its applications.
I recommend inserting this sentence directly into the product description:
Need a laboratory funnel? Pair your Microsidd Filter Paper with a suitable Borosil Glass Funnel for routine laboratory filtration.
This gives Google and AI systems a strong semantic relationship:
Filter Paper → Filtration → Laboratory Funnel → Borosil Glassware → Laboratory Needs
The product may be useful for:
Diagnostic & clinical laboratories
For applicable routine sample-preparation and filtration procedures.
Research laboratories
For general filtration and sample-preparation work where qualitative paper is appropriate.
Pharmaceutical laboratories
For applicable routine filtration and laboratory procedures.
Schools & colleges
For chemistry practicals, science demonstrations and laboratory education.
Universities & research institutions
For general teaching and research laboratory requirements.
Industrial laboratories
For appropriate quality-control and sample-preparation procedures.
Laboratory technicians, researchers & students
As a general-purpose laboratory filtration consumable.
This distinction will make the product page substantially more useful for Google and AI answers.
| Feature | Qualitative Filter Paper | Quantitative Filter Paper |
|---|---|---|
| Main purpose | General filtration & qualitative analysis | Quantitative/gravimetric analysis |
| Routine filtration | ✅ Common | Possible depending on grade |
| Ash requirements | Not necessarily ultra-low | Typically tightly controlled/low ash |
| Gravimetric analysis | Not automatically suitable | Specifically selected for this purpose |
| Typical use | General laboratory filtration | Precise quantitative analytical work |
| Microsidd 12.5 cm product | Qualitative | No |
Therefore, I would remove the current product-page statement suggesting this particular paper is for quantitative gravimetric analysis unless you have documentation confirming the required quantitative characteristics.
