Abstract
A testing device includes an elongated member and a tube assembly. The tube assembly has a first end and a second end. The tube assembly is configured to receive the elongated member at the second end. The tube assembly includes a plurality of chambers, including a first chamber and a second chamber. The first chamber and the second chamber are separated by a membrane. The tube assembly further includes a spring positioned at the second end of the tube assembly. The tube assembly further includes a spring retainer configured to prevent the spring from decompressing when in a locked position and permit the spring to decompress when in an unlocked position.
Claims53
A device comprising:
- an elongated member;
- and
- a tube assembly having a first end and a second end, the tube assembly configured to receive the elongated member at the second end, the tube assembly including:
- a plurality of chambers, including a first chamber and a second chamber, the first chamber and the second chamber being separated by a membrane;
- a spring positioned at the second end of the tube assembly;
- a spring retainer configured to prevent the spring from decompressing when in a locked position and permit the spring to decompress when in an unlocked position.
A method for conducting chemical reactions, comprising:
- inserting a swab in a first chamber of a testing device, the first chamber containing a first fluid mixture;
- decompressing a first spring positioned in a first spring chamber of the testing device, the first spring decompression causing the fluid mixture in the first chamber to flow into the first spring chamber of the testing device, the fluid mixture being filtered by silica en route to the first spring chamber;
- and
- decompressing a second spring positioned in a second spring chamber of the testing device, the second spring decompression causing a second fluid within the second spring chamber of the testing device to be filtered by the silica en route to a second chamber.
A method for conducting chemical reactions, comprising:
- inserting one end of an elongated member into a second end of a tube assembly such that the one end of the elongated member extends into a first chamber of the tube assembly;
- decompressing a spring positioned at the second end of the tube assembly by unlocking a spring retainer of the tube assembly;
- and
- puncturing a membrane separating the first chamber of the tube assembly from a second chamber of the tube assembly such that the one end of the elongated member extends into the second chamber of the tube assembly.
