The invention concerns a filtration assembly (1) for microbiological testing and a method of using the filtration assembly for that purpose. The filtration assembly (1) comprises a ring-like membrane support (10) holding a filtration membrane (11), a cylindrical reservoir (20) of which opposite axial ends have openings and one axial opening is removably and fluid-tightly attachable to the membrane support (10) to define a sample volume adjacent to the filtration membrane (11) on one axial side of the membrane support (10); and a drain member (30) removably and fluid tightly attachable to the membrane support (10) to define a drain channel space adjacent to the filtration membrane (11) on an opposite axial side of the membrane support (10).

The present invention relates an indicator system for assessing a reduction state of unconsolidated material that includes a delivery tube defining an interior chamber, and a substrate disposed within the interior chamber and including a reactive coating thereon. The reactive coating is at least partially removable from the substrate upon exposure to a reducing condition of unconsolidated material over a period of time. An indicator device including a reactive coating comprising a manganese oxide is also disclosed.

Provided herein is an integrated sampling and testing device, comprising a sampling device that comprises a syringe and specimen collector, and a testing device that comprises a cap, cylindrical container, and adaptor configured for sampling or testing.

Provided is a gene amplification apparatus. The gene amplification apparatus includes a supply roller, a roll-type film chip which has a plurality of polymerase chain reaction (PCR) chambers, with which PCR samples are filled, and is wound around the supply roller, a heating roller configured to rotate after being pressed against the film chip and then induce a PCR, a plurality of heating blocks which are disposed on a circumferential surface of the heating roller at preset intervals and brought into contact with the film chip, and a discarding roller configured to discard the film chip which passes the heating roller and on which the PCR is performed.

A transfer container for a fluid includes a tube, the tube including a conical portion at one end, the tube defining an interior space and one or more fluid passages configured to allow flow of fluid into or out of the interior space of the tube. The transfer container also includes a connector configured to seal the end of the conical portion when the connector is joined only to the conical portion and a pressure control mechanism configured to increase or decrease a pressure in the interior space of the tube. The transfer container can be used in a method including connecting fluid lines to the fluid passages, adding a fluid including cryoprotectant and cells, centrifuging the transfer container, and then connecting the transfer container to a second fluid transfer container containing another fluid. This allows the sterile transfer of fluids and separation of cells from cryoprotectant.

Apparatus is provided including a tube and a plunger sized and shaped to be inserted into the tube. A distal end of the plunger is shaped to define one or more first passageways therethrough, and the plunger is shaped to define one or more compartments in fluid communication with the first passageways. A filter is coupled to the distal end of the plunger. The plunger is shaped to define a second passageway that passes through the plunger from a proximal end of the plunger to the distal end of the plunger, and is positioned to facilitate testing of the filter. The apparatus is configured such that while the plunger is advanced within the tube while fluid is within the tube, the fluid in the tube is pushed through the filter, through the first passageways, and into the one or more compartments. Other embodiments are also described.

A sample pretreatment tube includes a first tube receiving a primary reagent and a second tube receiving a secondary reagent, wherein the sample pretreatment tube can easily perform sequential reactions by allowing a primary reaction solution to be immediately discharged from the first tube to the second tube by breaking a separation membrane formed at a lower end of the first tube using a pipette, and can limit an insertion depth of the pipette using a stopper formed inside the first tube, thereby preventing damage to the second tube due to the pipette while allowing a space to be formed inside the first tube to facilitate discharge of a primary reaction solution, thus making it possible to immediately perform secondary reaction.

A loading device for loading pellets into reactor tubes has a modular design, which can be taken apart, moved through a manway, and then reassembled simply by stacking one part on top of another. A reciprocating slide plate and a vibrator work together to meter pellets through the loading device and into the reactor tubes.

Systems, methods, and collection devices are disclosed for rapid, local PCR testing. The PCR testing system may be configured for use with a disposable sample collection device that includes a swab configured for collecting a biological sample from a patient; and a sample container configured to receive the swab and separate a bulk quantity of the biological sample from the swab for containment in a bulk collection chamber, which is located with the sample container, wherein the sample container is configured to meter a selected volume of the biological sample into a PCR sample tube, which contains a lyophilized master mix, releasably attachable to the sample container.

A container cap liner that that facilitates the storage of gases and various volatile organic compounds (VOCs). More particularly, the container cap liner reduces the loss of gases and various volatile compounds thereby providing for relatively longer storage periods with relatively more accurate analytical analysis.
