Abstract
A liquid storage and dispensing system, and methods for its use in the storage, shipping, and accurate dispensing by manual or automated methods, of, for example, precious biologic samples such as protein, DNA or RNA, with minimal contamination, oxidation, and evaporation, the system having: an essentially cylindrical storage barrel with a flange at its open end and a port and delivery tip at the closed end; a piston with a seal, where the piston closely matches the shape of the closed end of the barrel to minimize dead volume; and a cover to seal the delivery tip during storage such as cryostorage.
Claims20
A liquid storage and dispensing system comprising:
- (a) a storage barrel including a cylindrical bore having an open proximal end and a closed distal end having a port, wherein the port exits the storage barrel through a delivery tip;
- (b) a piston slideably disposed within the storage barrel, the piston having a proximal end with a handle, a distal end adapted to fit the distal end of the storage barrel, and a seal contacting the bore and disposed about the circumference of the piston between the distal and proximal ends of the piston;
- (c) a cover adapted to engage the delivery tip and seal the port;
- and
- (d) a sensing means adapted to sense the presence or absence of liquid in or on the delivery tip for adjusting motion of the piston according to an output of the sensing means.
