5ml Sterile Positive Displacement Pipette Tip Filter

I. Product Overview

The 5ml Sterile Positive Displacement Pipette Tip Filter is a core laboratory consumable specifically designed for medium-to-large volume liquid transfer. Featuring a composite structure of medical-grade polypropylene (PP) housing and ultra-high molecular weight polyethylene (UHMWPE) sintered filter element, this product undergoes rigorous sterile processing to maintain operational convenience at 5ml capacity while incorporating a precision filtration barrier. It effectively isolates aerosols and particulate contaminants, widely applied in biotechnology, chemical analysis, and sample preprocessing workflows.

The product's core innovation lies in the dual-capability breakthrough of "large volume + precision filtration"—delivering efficient 5ml pipetting operations while achieving contamination control standards equivalent to small-volume procedures through advanced filter technology, filling the protection gap in large-volume pipetting scenarios.

II. Core Competitive Advantages

Process Innovation

- Positive Displacement Fluid Dynamics Design: Optimized flow channel curvature specifically for 5ml large-volume applications, eliminating vortex formation and liquid retention to ensure complete transfer of viscous samples (e.g., serum, glycerol solutions)

- Deep Sintered Filter Technology: UHMWPE particles form three-dimensional interconnected pore channels through high-temperature, high-pressure sintering, delivering 3× higher dirt-holding capacity than conventional membrane filters and extending single-use lifecycle

- Integrated Injection Molding Process: Filter element and tip housing bonded without adhesive, eliminating chemical leaching risks and demonstrating resistance to organic solvents (ethanol, isopropanol, DMSO)

Manufacturing Excellence

- Proprietary Equipment Matrix: Dozens of self-developed sintering equipment, precision injection molding machines, fully automatic cutting machines, and ultrasonic welding production lines enable complete in-house control from raw materials to finished products

- Flexible Capacity Configuration: Monthly production capacity exceeds 50 million pieces, with 5ml specification daily output reaching 1.5 million pieces; emergency order response cycle compressed to 5-7 days

- Rapid Mold Development: Independent mold design and processing capabilities enable non-standard specification development in just 15-20 days, significantly faster than the industry average of 45 days

Cost Optimization Solutions

- Tiered Pricing Strategy: Unit price as low as $0.0015 for million-piece orders, with further reduction to $0.001 for orders exceeding 5 million pieces

- Zero-Barrier Sample Policy: Sample price approximately $0.01 per piece (¥0.0686), supporting mixed testing of full specifications from 10μl to 10ml to minimize validation costs

Quality Control System

- Dual Composite Sterilization: Gamma irradiation sterilization (dose 25-45kGy) combined with ethylene oxide residue control, ensuring SAL (Sterility Assurance Level) of 10⁻⁶

- Batch Comprehensive Inspection: Sampling rate ≥5% per batch, testing includes visual integrity, filter bubble point, seal integrity, sterility, and endotoxin levels

- Traceability Management System: Full barcode tracking from raw material receiving to finished product shipping; any quality anomaly can be traced to specific machine and operator within 2 hours

VI. User Testimonials

"Our laboratory processes over 500 5ml samples daily. The filter design of these tips is remarkably reliable—we've never experienced clogging or leakage. Most importantly, the price is only 1/5 of imported brands, saving us over ¥300,000 annually in consumables budget."

—— Director Zhou, Platform Director, National Biomedical Research Institute

"Used in GMP workshops for diagnostic reagent production, the supplier's ISO certification and complete COA documentation helped us successfully pass FDA on-site audits. Batch stability is excellent with no quality fluctuations during two years of continuous use."

—— Ms. Liu, Quality Director, IVD Listed Company

"The 12.5mm extended filter design is very thoughtful—when handling high-viscosity samples with cellular debris, the larger filtration area reduces clogging. Suzhou Jiahao's technical team also adjusted filter density according to our specific requirements, demonstrating highly professional service."

—— Chief Technician Wang, Clinical Laboratory, Shanghai Top-Tier Hospital

"We've partnered since 2019, and what impressed me most is their delivery flexibility. During the pandemic last year, we urgently needed 2 million additional 5ml tips—they completed production and shipping within 5 days, ensuring our COVID-19 test kit manufacturing."

—— Mr. Chen, VP Procurement, Biotechnology Group

"During sample testing, we compared products from 5 suppliers. Jiahao's tips scored highest across three dimensions: compatibility, filter integrity, and price. Particularly, the perfect fit with our Eppendorf pipettes required zero adjustment."
