MECOJI® Low-Adsorption 8-Strip Tubes
Medical-grade · Ultra-thin Wall · High Sealing — designed for low-template & high-sensitivity quantitative PCR
MECOJI® Low-Adsorption 8-Strip Tubes
Precision-molded from medical-grade polypropylene (PP), the MECOJI® low-adsorption 8-strip tubes combine a ≥112° low-adsorption surface with ultra-thin walls, superior sealing, high optical clarity and clean manufacturing — ideal for low-template, high-sensitivity quantitative PCR applications such as methylation assays, ctDNA and NGS library preparation.
0.2 mL · Optical Flat Cap
Seven Core Specifications
Low Adsorption
Contact angle ≥112°, significantly reducing non-specific adsorption of DNA/RNA, proteins and enzymes to improve recovery of low-template samples.
Medical-grade Resin
Medical-grade PP — free of DNase/RNase, pyrogens and PCR inhibitors, providing a pure carrier for high-sensitivity reactions.
Ultra-thin Wall
<0.2mm ultra-thin wall with ±0.1°C thermal uniformity — fast, even heating and cooling for stable Ct values.
High Sealing
Evaporation rate <1% — no cap blow-off or leakage at 105°C / -40°C / 60KPa, reliable through high-temperature cycling and frozen storage.
Optical Clarity
Transmittance >90% with an optical flat cap — reduced fluorescence attenuation, ideal for quantitative PCR.
Fill Precision
Fill precision CV <3% with high batch-to-batch consistency — ensures reproducible pre-filled IVD kits and bulk testing.
Clean Manufacturing
ISO 13485 certified; produced in class 100K/10K cleanrooms with full process traceability.

Typical Applications
Methylation Assays
qMSP / MethyLight — carriers for low-concentration single-stranded DNA after bisulfite conversion.
ctDNA / NGS Library Preparation
Low-template liquid biopsy and next-generation sequencing library prep — low adsorption minimizes precious sample loss.
IVD Kit Integration
All-in-one pre-filled kits — CV<3% ensures consistent batch filling, compatible with quantitative PCR.
