❓ Frequently Asked Questions

Q: What stir-head geometries are available?
A: We offer flat, spiral, and fully custom stir-head designs. The spiral design is ideal for efficient mixing, while flat heads are suitable for gentler agitation.

Q: What is the benefit of PTFE coating on a stirring needle?
A: PTFE coating provides excellent chemical resistance and prevents sample adhesion, ensuring consistent mixing performance and easy cleaning.

Q: Is this needle compatible with my specific analyzer model?
A: Our stirring needles are designed for use with major automated laboratory reaction systems. To confirm compatibility, please contact us with your instrument make and model.

Q: What is the minimum order quantity (MOQ)?
A: For standard stirring needles, MOQ is 5–10 pieces depending on the model. Sample orders for testing are encouraged.

Q: What is the typical delivery time?
A: For standard models with stock (semi-finished products), we ship within 1 week. For custom orders manufactured to your specifications, lead time is typically 1–2 months, depending on complexity and quantity.

Q: Can you manufacture needles according to my drawing?
A: Yes, we offer OEM/ODM customization. Send us your drawing or specifications for a quotation.

Q: Are these needles sterile?
A: No, these are non-sterile components designed for use in automated analyzers. If you require sterile needles, please specify for special handling.
