Protecting sensitive reaction environments and equipment from particulate and microbial contamination is essential for experimental accuracy. LabFriend provides a specialized selection of in-line filters, located within the filtration section of our distillation, separation, and filtration department. These professional filtration units are engineered for high-efficiency air and gas purification in analytical and life science laboratories.
Why Choose Professional In-Line Filters?
Our curated collection of in-line hardware is designed for sterile integrity, chemical resistance, and high throughput:
- Sterile Air Filtration: We stock Sartorius Stedim Air Filtration Units and Midiart 2000 units, available in sterile and non-sterile formats with 0.2 µm or 0.45 µm pore sizes for critical venting and gas purification.
- High-Performance PTFE Membranes: Utilize LLG In-line Filters featuring PTFE membranes and durable polypropylene (PP) housings, offering broad chemical compatibility and hydrophobic protection.
- Versatile Sizing: Explore various diameters, including 50 mm and 62 mm units, designed to fit easily into standard laboratory tubing lines.
- Biopharmaceutical Quality: Our range includes Sartorius Filter Units No. 16508-B, trusted for high-integrity filtration in demanding research and production environments.
LabFriend supplies in-line filters from the world's leading specialists in separation technology:
- Sartorius: A global leader in laboratory and process technology, providing premium Stedim air filtration units and Midiart systems for sterile gas handling.
- LLG Labware: Offers high-quality, cost-effective in-line filters with PTFE membranes for routine laboratory air and gas filtration.
Pure gas streams are vital for sensitive synthesis; to further enhance your filtration and distillation workflow, we recommend exploring these related categories:
- Microfilter Plates: For high-throughput liquid sample preparation, explore AHN Biotechnologie 96-well plates.
- Gas Wash Bottles: Use Lenz-Laborglas Drechsel bottles for chemical gas scrubbing before final in-line particulate filtration.
- Tubing Adapters: Securely connect your in-line filters to various glass systems using Lenz-Laborglas NS joint adapters and DWK Duran screw caps.
- Stopcocks & Valves: Regulate the flow of gases through your filtration line using Lenz-Laborglas PTFE-plug stopcocks.
Unsure if a 0.2 µm or 0.45 µm PTFE membrane is required for your specific venting application? Our team provides local technical support to help you find the perfect filtration solution with fast shipping and competitive pricing.
Frequently Asked Questions
1. What is the main use for in-line filters in a lab?
They are primarily used for sterile venting of containers, such as fermenters or carboys, and for the removal of microorganisms and particulates from air or gas streams entering sensitive equipment.
2. Why is PTFE a preferred membrane material?
PTFE (polytetrafluoroethylene) is naturally hydrophobic, meaning it repels water and prevents "wetting out" that can block gas flow, while also offering exceptional chemical resistance.
3. Are Sartorius Stedim units available in sterile packaging?
Yes, Sartorius offers both sterile and non-sterile air filtration units, such as the 0.2 µm and 0.45 µm 62 mm models, to suit different laboratory requirements.
4. What connection sizes are available?
Most in-line filters, like the LLG and Sartorius models, feature hose barb connections designed to fit standard laboratory tubing diameters for easy integration.
