Disposable Pipette Tips

A: First, check if the tips match your pipette's brand and volume range (e.g., 10μL tips for 0.1–10μL pipettes). Our universal tips fit most mainstream brands like Eppendorf, Gilson, and Rainin, with a flexible proximal design ensuring a tight seal. For critical experiments, verify via a water-weight test-an error ≤±1% indicates qualified compatibility. We also provide compatibility certificates aligned with DIN EN ISO 8655 standards.

A: Standard tips: For routine aqueous/ buffer transfers, cost-effective with basic polypropylene construction.
Filtered tips: Built with PP+PE hydrophobic filters to block ≥0.2μm aerosols, critical for PCR or radioactive samples to prevent pipette/sample cross-contamination.
Low-retention tips: Plasma-modified surfaces reduce protein/nucleic acid adhesion, cutting sample loss to ≤0.1%-ideal for precious reagents.

A: We offer three bulk options:
Bulk bags: Most economical for general use, requiring manual racking (suitable for low-volume workflows).
Pre-racked tips: Preloaded in 8×12 or 96-well formats, saving time for multichannel pipetting/automation (sterile options available).
Refill systems: Stackable, reusable racks with minimal plastic waste-certified by My Green Lab for sustainability, perfect for high-throughput labs aiming to reduce costs and environmental impact.

A: Yes. Our premium tips undergo batch-specific QC: they are DNase/RNase-free, endotoxin <0.001 EU/ml, and sterile (gamma-irradiated with SAL 10⁻⁶ assurance). They're also PCR-performance tested to ensure consistent Ct values (CV <2%) and meet USP Class VI biocompatibility standards, making them safe for cell culture and molecular biology workflows.

A: Routine labs (e.g., general dilutions): Standard non-sterile bagged tips offer the best value, with no compromise on basic accuracy.
Research labs (e.g., proteomics): Low-retention tips reduce reagent waste (saving long-term costs) despite higher upfront pricing.
Clinical labs (e.g., diagnostic PCR): Sterile filtered tips are non-negotiable for regulatory compliance, but our bulk pre-racked options lower per-unit costs by 15–20% vs. small packaging.

A: Our specialty tips use high-purity PTFE/PFA materials (instead of standard PP) to withstand 121°C autoclaving and resist acids, alkalis, or organic solvents like chloroform. Standard PP tips tolerate 0–60°C, while cryogenic-compatible variants (with anti-impact modifiers) remain intact at ≤-40°C for frozen sample transfer. Contact us for a chemical compatibility chart tailored to your reagents.

A: For standard tips: 1–3 business days for major cities, 4–6 days for remote areas (air-freight options for urgent needs). Customized tips (e.g., 384-well conductive variants for automation) have a 2–3 week lead time. All orders include batch-specific COAs (Certificate of Analysis) and a 100% replacement guarantee if tips fail to meet accuracy/sterility standards.

A: Yes. All our tips are made of 100% recyclable polypropylene. After decontamination (autoclaving/chemical treatment), they can be processed via standard plastic recycling streams. We also provide ACT (Accountability, Consistency, Transparency) labels from My Green Lab, detailing our manufacturing facilities' energy/water savings and waste reduction metrics-critical for ESG reporting.
