These products (e.g. immunogold products, L.R. White Resin), because of their instability, require they be shipped cold. The purpose of stating our policies and recommended instructions is to reduce the chances for misunderstandings.
SPI Supplies packages items requiring refrigeration with a "refrigerator gel" which keeps the item cold until delivered to the customer. It is our experience that even under the most extreme of conditions, the gel pack will assure the shipment arrives cold, provided delivery is made within 72 hours of shipment from SPI. Delays due to circumstances beyond our control can not be our responsibility. Such delays are the risk of the customer, not SPI Supplies. To guarantee the fastest possible delivery, all cold ship items are sent by overnight courier service in the US and Express courier service internationally.
