FAQ
Q1: Do you offer free samples?
Yes, we can supply free samples (normally 5‑10pcs) for your assessment. Shipping cost is on buyer's side, or freight can be discussed case‑by‑case.
Q2: What is minimum order quantity (MOQ)?
MOQ varies for different items. MOQ is 5 cartons for glass flasks, 1 carton for plastic labware, and 5 cartons for other disposable glass goods. Pallet packing is highly recommended to avoid glass breakage.
Q3: What payment methods do you accept?
We accept T/T (bank transfer) and Alibaba Trade Assurance.
Q4: Can I add my own design or logo to the product?
Yes, OEM / ODM services are available.
Q5: Can you provide CE and ISO for your products?
Yes, we can provide full technical documentation including CE, ISO and COA. FDA documents are available for certain products.
Q6: How about the packing for glass flasks?
Items are packed in export‑qualified corrugated cartons. Pallet loading is strongly advised to reduce breakage risk for long‑distance sea shipments.
Q7: What is your lead time?
Normally 15‑25 working days after we receive your deposit. Exact lead time depends on your order quantity.
Q8: What is the difference between straight‑neck and narrow ground‑neck Erlenmeyer flask?
Straight‑neck flasks fit rubber or silicone stoppers and have no ground joints. They are more cost‑efficient for regular mixing, heating and culturing work.
Q9: Can this glass Erlenmeyer flask be heated directly over open flame?
We suggest using asbestos gauze during heating for even heat distribution, to avoid local overheating and glass cracks.
Q10: What should I do if receiving broken goods?
Please take photos of outer cartons and broken parts within 7 days of goods arrival. We will check and arrange compensation accordingly.
