Products Syringe filter products from LTT help remove particulates and protect instruments for consistent analytical results. As Zhejiang Liquan Biotechnology Co., Ltd. (brand: LTT), we manufacture lab consumables in a 100,000-class cleanroom under an ISO13485-certified quality system.
Our range covers multiple membranes, pore sizes, and diameters in sterile and non-sterile formats to fit HPLC/UHPLC, QC, research, and education workflows.
Select membrane chemistry for solvent compatibility, analyte recovery, and throughput. Common options include Nylon (broad compatibility for mixed systems), PTFE (hydrophobic, excellent for aggressive organics and venting), PVDF (low protein binding with good compatibility), PES (very low binding, fast flow for aqueous media), and CA (low extractables for buffers).
Hydrophobic and highly resistant to strong organic solvents and corrosives; pre-wet when filtering aqueous samples.
Hydrophilic with very low protein binding and fast flow; ideal for buffers, media, and sensitive analytes.
| Diameter | Typical Volume | Use Case |
|---|---|---|
| 4–5 mm | ≤0.5 mL | Microscale, precious samples |
| 13 mm | 0.5–10 mL | Routine vial preparation |
| 25–30 mm | 10–100+ mL | Higher particulates, faster throughput |
Choose 0.22 µm for fine particulates and UHPLC, or 0.45 µm for routine HPLC and general clarification. Sterile options suit aseptic and cell culture needs; non-sterile suits general prep.
Filters support HPLC/UHPLC sample prep, dissolution testing, environmental water analysis, pharmaceutical QC, and biotech research. Proper selection protects columns and detectors and improves baselines.
For aqueous and biological samples, use hydrophilic membranes such as PES or CA. Nylon or PVDF fit mixed aqueous/organic systems. For aggressive solvents or gases, choose hydrophobic PTFE. Match pore size to method sensitivity to balance recovery and backpressure.
Partner with LTT for OEM and private-label projects. Customize membrane, pore size, diameter, color coding, branding, and packaging (sterile or non-sterile) to align with your workflow.
We combine cleanroom manufacturing, an ISO13485 quality system, and strong mold design with scalable capacity for stable supply. Our R&D team supports method-driven customization for testing institutions, biotech, healthcare, pharma development/production, and education.
Request specifications, samples, and pricing based on your solvent system, pore size, diameter, and sterility needs. Contact LTT—your B2B syringe filter manufacturer and supplier—for technical recommendations, lead time, and batch availability.
