Shipping Time

Standard orders

How long will it be before my standard order will ship?
If products are in stock, shipments will be processed within 1-2 business days. Overnight expedited delivery is available (at cost).

Special orders

How long will it be before my special order glass bottom dishes will ship?
For special order glass bottom dishes, lead times are typically 4-8 weeks. The lead time mainly depends on the batch sterilization, which occurs once every 6 weeks (All dishes are sterilized off-site using gamma irradiation). The lead time can be shortened to 2-4 weeks if an initial order can be shipped non-sterile (In this case, the customer will need to sterilize the dishes for 30 minutes under the UV light in a cell culture hood. With proper planning, subsequent orders would be sterilized in the normal manner using gamma).For more accurate lead times on specific orders, please ask our customer service representatives.

Free Samples

How long will it be before my free samples will ship?
Precise delivery dates for Free Samples are not guaranteed. Shipment is usually made within 5 business days. If your project is time-sensitive, please do not schedule your experimental research based on receiving your requested free sample dish/plate.
