Ordering Tips: Save Time and Money
  • Order a full box, save on shipping

  • We have 6 basic box sizes, and when you fill a box, you often save on shipping costs per unit. If you are ordering plasma only, consider ordering 2,5,8,12 or 24-25 units. You can also order blood administration sets (BAS) – check out our full box alternatives.

  • Consider 2nd Day Air for large orders

  • A larger volume of frozen product will self-insulate and arrive quite frozen even to Florida and Texas. We only recommend this option for orders of 20 liters or more.

  • Let us know how “hot” the weather is at your location

  • Sometimes with the heat of spring and summer, our product may arrive with the outer units slightly defrosted. Do not be concerned. Our product can be refrozen upon arrival as long as these are some ice crystals or slush in the unit. If you are experiencing extremely high temperatures, please let us know when you order, so we may add ice packs accordingly.

  • LI provides free replacement of expired plasma. If you have a unit that is expired, just give us a call and tell us the serial number. We will send replacement plasma free of charge, you just pay the shipping.
