Shipping & Storage

Due to various storage temperatures for our products, shipping and handling fees will be calculated at time of shipment based upon the orders recommended shipping requirements.

Shipping Temperature and Storage Temperature
Products may ship at temperatures different than those required for storage. Most of our products are stable at room temperature for many days, but we recommend storage in a refrigerator or freezer to prevent the growth of microbes and to prolong shelf-life. Therefore, to reduce shipping costs for our customers, products with recommended storage at 4°C or -20°C may ship with an ice pack or at ambient temperature. These products may thaw without affecting product performance. When you receive the product, place it under the recommended storage conditions. Products with recommended storage at ultra low temperature (-70°C) that also ship on dry ice should arrive frozen. If a product you received was shipped on dry ice and thawed during transit, please contact customer service.

Blue and Dry Ice Shipments
Orders requiring blue or dry ice are shipped via overnight express service. Blue ice and dry ice overnight orders are shipped according to the following schedule:
Monday-Thursday: All “in stock” orders received by 10:00 a.m. Pacific Standard Time will be delivered the following business day.

CHANGES: Orders arising hereunder may be changed or amended only by written agreement signed by both Buyer and Seller, setting forth the particular changes to be made and the effect, if any, of such changes on the price and time of delivery. Buyer may not cancel this order unless such cancellation is expressly agreed to in writing by Seller. In such event, Seller will advise Buyer of the total charge for such cancellation, and Buyer agrees to pay such charges, including, but not limited to, storage and shipment costs, costs of producing non-standard materials, costs of purchasing non-returnable materials, cancellation costs imposed on Seller by its suppliers, and any other cost resulting from cancellation of this order by Buyer which is permitted by Seller.  Certification of such costs by Seller’s independent public accountants shall be conclusive on the parties hereto.
