Sterile Filtration Products Supplier in India — Syringe Filters, Membrane Filters and Capsule Filters for Pharma, Research and Diagnostic Labs
Sterile filtration is one of the most critical steps in pharmaceutical manufacturing, analytical sample preparation, and microbiology workflows. A single contaminated sample can invalidate an entire batch of test results, delay product releases, and trigger costly audit failures. Yet many laboratories in India still struggle to find a reliable sterile filtration products supplier who can deliver genuine, certified products with proper documentation and technical guidance.
Scientific Edge is a Delhi-based, ISO 9001:2015 certified supplier of laboratory filtration products with pan-India delivery. As an authorized channel partner for Pall, Whatman (Cytiva), Millipore, and Axiva, we supply the complete range of syringe filters, membrane filter discs, capsule filters, and vacuum filtration devices that pharma QC labs, biotech research facilities, diagnostic centres, and academic institutions need for their sterile filtration workflows.
This guide covers the major categories of sterile filtration products, how to select the right filter for your application, and why choosing an authorized supplier matters for your lab's compliance and result integrity.
What Is Sterile Filtration and Why Does It Matter?
Sterile filtration is the process of removing bacteria, particulates, and microorganisms from liquids and gases using membrane filters with pore sizes of 0.2 um (0.22 um) or smaller. Unlike autoclaving or chemical sterilization, membrane filtration does not alter the chemical composition of heat-sensitive solutions — making it the preferred method for sterilizing culture media, buffers, pharmaceutical formulations, and biological reagents.
In regulated environments such as pharmaceutical QC laboratories and clinical diagnostic facilities, sterile filtration is not optional. Regulatory frameworks including WHO GMP, USFDA 21 CFR, and Indian Pharmacopoeia mandate validated filtration processes with documented proof of filter integrity. This means the filters themselves must come from authorized sources with lot-traceable Certificate of Analysis (COA) and validated pore size ratings.
Types of Sterile Filtration Products Available at Scientific Edge
Choosing the right sterile filtration product depends on your sample type, volume, application, and workflow requirements. Here is a comprehensive breakdown of the filtration product categories we supply across India.
1. Syringe Filters — For Small Volume Sample Preparation
Syringe filters are the most widely used sterile filtration devices in analytical and QC laboratories. They attach directly to a standard luer-lock syringe and provide quick, convenient filtration for sample volumes ranging from 1 mL to 100 mL.
Scientific Edge stocks the complete Pall Acrodisc syringe filter range, which is the industry standard for HPLC sample preparation, dissolution testing, and sterile filtration in pharma labs.
| Product | Code | Membrane | Pore Size | Diameter | Best Application |
|---|---|---|---|---|---|
| Acrodisc Syringe Filter (Nylon, DMSO-Safe) | 4433 | Nylon | 0.2 um | 25 mm | DMSO-based samples, organic solvents |
| Acrodisc Syringe Filter (Supor PES) | 4652 | Supor (PES) | 0.2 um | 32 mm | Biological samples, low protein binding |
| Acrodisc Syringe Filter (Supor PES) | 4614 | Supor (PES) | 0.2 um | 25 mm | General sterile filtration |
| Acrodisc Syringe Filter (Supor PES) | 4654 | Supor (PES) | 0.45 um | 25 mm | HPLC sample clarification |
| Acrodisc Syringe Filter (Supor) | 4187 | Supor (PES) | 0.8/0.1 um | 25 mm | Pre-filtration and fine filtration |
| V-Prep Syringe Filter (Nylon) | 4118 | Nylon | 0.45 um | 25 mm | High-throughput HPLC prep |
| Acrodisc Versapor Filter | 4489 | Versapor (Acrylic) | 5.0 um | 25 mm | Pre-filtration of turbid samples |
How to choose: Use Nylon syringe filters for aqueous and most organic solvent filtration. Choose Supor (PES) for protein-containing biological samples where low binding is critical. Use PTFE for aggressive chemical solvents and strong acids. When filtering DMSO-based pharmaceutical formulations, the Acrodisc 4433 with DMSO-safe nylon membrane is the standard choice.
2. Membrane Filter Discs — For Vacuum and Pressure Filtration
Membrane filter discs are flat circular filters used with vacuum or pressure filtration assemblies for medium to large volume filtration. They are essential in microbiology labs for bioburden testing, water quality analysis, and environmental monitoring.
| Product | Code | Material | Pore Size | Diameter | Pack Size |
|---|---|---|---|---|---|
| Ultipor Nylon Filter Disc | NR025100I | Nylon | 0.2 / 0.45 um | 25 mm | 100 per pack |
| Nylon Filter Disc | NX047100 | Nylon | 0.45 um | 47 mm | 100 per pack |
| Nylon Membrane | NR047100 | Nylon | 0.2 um | 47 mm | 100 per pack |
| Ultipor Nylon Filter Disc | NX025100I | Nylon | 0.45 um | 25 mm | 100 per pack |

| BioTrace NT Nitrocellulose Membrane | 66593 | Nitrocellulose | 0.45 um | Various | Per pack |
| PVDF Membrane Disc Filter | 66475 | PVDF | 0.2 / 0.45 um | Various | 100 per pack |
Nylon membrane filter discs from the Pall Ultipor range are the workhorses of analytical and microbiology labs. The 47 mm diameter discs are standard for vacuum filtration assemblies, while 25 mm discs are used in syringe filter holders for manual pressure filtration. Scientific Edge stocks these across multiple pore sizes for immediate dispatch.
3. Capsule Filters — For Process-Scale Sterile Filtration
When your lab needs to filter larger volumes — from 500 mL to several litres — capsule filters provide a sealed, ready-to-use filtration solution without the need for a separate filter housing. They are widely used in pharma manufacturing, media preparation for cell culture, and buffer filtration.
- AcroPak 20 Filter with Supor Membrane (Code 12202) — 0.2 um sterilizing-grade capsule for small batch processing
- AcroPak 20 Filter with Supor Membrane (Code 12203) — 0.8/0.2 um pre-filter and sterilizing filter in one capsule
- AcroPak 200 Capsule with Supor Membrane (Code 12941) — Higher capacity capsule for medium batch volumes
Capsule filters eliminate the risk of membrane handling contamination and reduce the time spent on filter assembly. For pharmaceutical clean rooms and tissue culture facilities, they are the preferred choice because of their validated bacterial retention and low extractable profiles.
4. Vacuum Filtration Devices — For Rapid Bench-Top Filtration
VacuCap and VacuCap PF vacuum filtration devices from Pall provide a complete, disposable vacuum filtration solution. They connect directly to a vacuum source and are designed for filtering buffers, culture media, and laboratory water.
