Shipping & Storage

Shipping Policy

Terms of our Shipping Policy are outlined below and apply to all products on

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.

Items stored at ambient temperature will be shipped via ground service unless otherwise requested at time of order checkout.

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.
  • Friday: All orders received by 3:00 p.m. Pacific Standard time will be shipped the following business day for next day delivery.
  • We do not ship on the following U.S. holidays: New Year’s Day; President’s Day; Memorial Day; Independence Day (Fourth of July); Labor Day; Thanksgiving (Thursday and Friday); and Christmas Day.

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.

Storage Policy

The storage conditions that a Biotium label recommends are deliberately conservative. Long term storage at low temperatures usually will increase the time that the product will remain within specification, unless specific instructions otherwise are provided (such as “do not refrigerate” or “do not freeze”).

Biotium labels and product information sheets may show a specific temperature for long term storage, or a temperature range that is adequate for long term storage. For all products, the implied range is as follows for the following storage conditions:

  • Room Temperature
    For Biotium products where the label indicates room temperature or RT, this implies storage in ambient conditions between 20°C and 30°C.
  • Refrigerator
    For Biotium products where the label indicates 4°C, this implies storage in a refrigerator that is between 2°C and 8°C.
  • Freezer
    For Biotium products where the label indicates -20°C, this implies storage in a freezer that is between -35°C and -5°C.
  • Ultra Low Temperature Freezer
    For Biotium products where the label indicates -70°C, this implies storage in an ultra low-temperature (ULT) freezer that is below -60°C.
