Cell culture environment monitoring system (6) for monitoring parameters relevant to cell growth in at least one culture dish (4) containing a cell growth medium (14), including at least one sensing device (22, 22′) configured to measure environmental parameters relevant to cell growth, and a tray (24) supporting said at least one culture dish. The sensing device is configured for mounting inside said culture dish at least partially within said cell growth medium, and comprises an RFID transponder (34). The tray (24) comprises an RFID base station (44) configured to interrogate the RFID transponder to obtain measurements of said parameters relevant to cell growth.

A collapsible container has a base having a lower hinge portion which includes a first lower hinge portion and a second lower hinge portion. The container also includes a plurality of upstanding side walls attached to the base having an upper hinge portion extending downwardly. The upper hinge portion includes a first elongate upper hinge portion and a second elongate upper hinge portion. The first lower hinge portion includes a first opening for receiving the first elongate upper hinge portion therein and also includes a flange for securing the first upper hinge portion thereunder. The second lower hinge portion includes a second opening correspondingly sized to receive the second elongate upper hinge member therein for limiting lateral movement between the side walls and the base.

A nursing bottle insert that stores a measured amount of powder. The insert resides inside the bottle along with a correspondingly measured amount of water for the sealed powder to mix with. The powder and the water are allowed to mix when desired by applying a force external to the bottle.

An apparatus and method for generating moisture standards in gases are disclosed. In particular, the invention relates to an apparatus for introducing a preselected amount of water vapor or other vaporized liquid into a flowing gas stream at a constant rate, which comprises a suitable syringe having a needle attached thereto; an evaporator attached to said needle, wherein the evaporator is located in the flowing gas stream; and a means for applying pressure to the syringe, such that water or other liquid may be delivered at a constant rate from the syringe through the needle into the evaporator. The invention also relates to a method for introducing a preselected amount of water vapor or other vaporized liquid into a flowing gas stream at a constant rate, which comprises providing a syringe having a needle attached thereto, wherein the syringe contains the water or other liquid to be vaporized; applying pressure to the syringe, such that water or other liquid is transferred at a constant rate from the syringe through the needle into an evaporator, said evaporator being attached to one end of the needle, and situated in the flowing gas stream; and allowing the water or other liquid to evaporate from the evaporator into the flowing gas stream. The apparatus and method of the invention are useful for the generation of low levels of moisture, and are especially useful where quick and reliable changes of moisture level in the gas is desired. Thus, the apparatus and method are useful in the generation of primary moisture standards for use in the calibration of moisture analyzing instruments, such as FTIR spectrometers.

Apparatus, systems and methods for performing gel electrophoresis using a monolithic electrophoresis unit that at least includes first and second buffer chambers containing buffer solution and a gel chamber containing a pre-cast gel, whereby all of these chambers are integrated into a pre-fabricated single unit that is ready for use. In performing gel electrophoresis, a top seal of this monolithic electrophoresis unit is removed, followed by removing a gel chamber seal from over the gel chamber, such that, buffer solution contacts the pre-cast gel within such gel chamber. Target samples are loaded into the gel chamber for contact with the pre-cast gel, a reusable lid is attached to the top surface of the monolithic electrophoresis unit, and an electrical connection is provided through the reusable lid into the monolithic electrophoresis unit for performing electrophoresis on the pre-cast gel.
