Device for storing, transporting and/or handling a liquid and method of handling a sterile or aseptic liquid
A device for storing, transporting and/or handling a liquid or liquids and methods for using the device are described. The device is suitable for use with sterile or aseptic liquids, particularly with large liquid volumes such as 10-1000 liters or more, and avoids the need for bags, bins and carriers commonly used for storing and transporting large volumes of liquids. The device comprises a coiled tubing. The coiled tubing can be loaded onto a spool to support the coiled tubing. The tubing can be filled, sealed, stored and transported in a more robust manner than previously achieved with bags, bins and carriers.
1. A method of handling a sterile or aseptic liquid comprising:
a) filling a coiled tubing with a sterile or aseptic liquid, wherein the coiled tubing has a size and length sufficient to contain a liquid volume of at least 10 liters to at least 1000 liters;
b) sealing the ends of the coiled tubing;
c) storing and/or shipping the coiled tubing filled with liquid; and
d) dispensing some or all of the liquid from the coiled tubing, further comprising filtering the liquid simultaneously or sequentially with dispensing the liquid from the coiled tubing.
2. The method of claim 1 further comprising a spool for supporting the coiled tubing.
3. The method of claim 1 , wherein the tubing comprises a gamma sterilization-stable, thermoplastic material and is gas-impermeable, caustic-stable, pressure-resistant, pH-stable, impact-resistant, particle-free, low-extractable, low-leachable, temperature-stable, or a combination thereof.
4. The method of claim 1 , wherein the tubing comprises multiple lumens and one or more lumens is filled with a liquid.
5. The method of claim 1 , wherein the tubing comprises at least one sterile connector at one end of the tubing or comprises a sterile connector at each end of the tubing.
6. The method of claim 1 further comprising recirculating the liquid within the tubing using a recirculating pump connected to the tubing.
7. The method of claim 1 further comprising dispensing the liquid from the coiled tubing by gravity flow, pumping, or introducing pressurized air.
8. The method of claim 1 further comprising monitoring the temperature, pH, pressure, gas content, flow rate, or a combination thereof, of the liquid in the coiled tubing using one or more sensors connected to the tubing.
9. The method of claim 1 , wherein the tubing is composed of a single material or a composite of materials.
10. The method of claim 1 , wherein the liquid comprises a pharmaceutical, buffer, media, nutrient, or a combination thereof.
11. The method of claim 1 further comprising raising, maintaining and/or lowering the temperature of one or more liquids in the tubing.
