Stainless Steel Manifolds Filtration Apparatus Three Branch
Brand: Gamalab. Features include high quality 316L stainless steel construction and a compact three-branch design. Best for small to mid-size filtration workflows that require a simple, reliable distribution manifold with corrosion resistance. The data suggests affordability paired with dependable material quality, making it suitable for routine lab filtration tasks. Consider this when you need a straightforward three-branch setup without extra complexity. Caution: verify compatibility with your specific filtration cups and gaskets to ensure a tight seal in long runs.
Lab 3-Branch Autoclaved Manifolds Vacuum Filtration W/Glass Funnel 300ml
Brand: Generic. This unit uses a 300 mL high-transparency glass filter cup and a three-stage integrated filtration system. Best for labs prioritizing clear observation during filtration and multi-stage processing in a compact footprint. Better for processes requiring glass visibility, though glass may require careful handling. Limitation: glass components may be more vulnerable to breakage than all-metal options.
1/3/6 Way Branches Vacuum Filtration Manifolds
Brand: DFUVFKGOP. Features include independent control valves on each bracket, enabling flexible use and high efficiency. It supports simultaneous testing of three or six samples. Best for labs needing scalable throughput and precise control per branch. Caution: ensure valve seals meet your solvent compatibility requirements to prevent leaks during extended runs.
12 Port Vacuum Manifold Set-Complete
Brand: eCon Lab Supply. Configurations include 12, 16, and 24 ports for parallel sample processing. Best for high-throughput filtration in SPE workflows or multi-sample elution. Clear glass chamber and lid simplify observation and monitoring. Caution: larger port counts require more space and a stable mounting setup to prevent tipping during use.
Lab 3-Branch Autoclaved Manifolds Vacuum Filtration W/Stainless Steel Funnel 300ml
Brand: LCGJZTPN. Features include SS 304 material, 300 mL stainless steel filter cup, and a three-unit filtration setup. Best for labs requiring autoclavable stainless steel components for repeated sterilization cycles. Better for maintaining sterility in clean environments. Limitation: stainless steel components add weight and may require robust supports in some bench configurations.
SUS316 Three-Unit Solvent Filtration Device Lab 3-Branch
Brand: LDGSUPH. Notable for SUS316 material and a 300 mL filter cup, providing robust resistance to corrosive solvents. Best for solvent-heavy workflows where corrosion resistance matters. Choose this for high-purity filtration tasks, but verify compatibility with your specific solvents and seals to avoid issues with elastomer compatibility.
SUS316 Three-Unit Solvent Filtration Device Lab 3-Branch
Brand: LCGJZTPN. Features SUS 316 material and a three-unit filtration apparatus with a 300 mL stainless steel filter cup. Best for applications requiring high chemical resistance in a compact, multi-branch format. Limitation: higher cost and heavier weight than non-316 options.
DERNORD Tri Clamp 1.5 Inch 4 Port Manifold
Brand: DERNORD. Specifications include 38 mm (1.5″) pipe OD and a 50.5 mm ferrule size, suitable for 1.5″ tri-clamp fittings. Best for sanitary, process-integrated systems needing easy flow separation. Better for hook-up with standard tri-clamp piping. Caution: ensure compatibility with your existing tri-clamp sizes and gaskets to avoid leaks in continuous service.
Buying Guide
What matters most when choosing a lab manifold?
- Material and corrosion resistance: For solvent-heavy or autoclavable workflows, consider SUS316/304 stainless and 316L options.
- Port count and layout: Match the number of samples to your throughput needs; high-port models save time but require more space.
- Connections and fittings: Check tri-clamp compatibility, gasket materials, and valve types for leak-free operation.
- Observation and cleaning: Glass cups provide visibility, while stainless steel cups offer durability and sterilization ease.
- Maintenance: Autoclavable components simplify sterilization; consider ease of disassembly and cleaning in your lab protocol.
Frequently Asked Questions
- What is a vacuum manifold used for in the lab?
It distributes vacuum to multiple filtration lines, enabling parallel sample processing and filtration.
- Which material is best for solvent filtration manifolds?
SUS316 or SUS304 stainless steel provide strong chemical resistance; choose based on solvent compatibility.
- How many ports should I need?
Plan based on the number of samples processed simultaneously; larger port counts improve throughput but need more bench space.
- Are glass filter cups safe for autoclaving?
Glass cups can be autoclaved in some configurations; verify manufacturer guidelines to avoid breakage.
- What is the advantage of a tri-clamp manifold?
Tri-clamp fittings offer quick assembly/disassembly and reliable seals for sanitary applications.
- Can I mix different brands in the same filtration setup?
Mixing is possible if fittings, seals, and valve types are compatible; ensure leak-free connections and solvent compatibility.
