Instrument and method for automatically heat-sealing a microplate
A heating device for heating a thermally fixable sealing cover disposed over the microplate adjacent the wells, a cooling device for actively cooling the microplate and a controller set up to control activity of the heating and cooling devices in a manner to heat the sealing cover so as to thermally fix it to the microplate and to actively cool the microplate so as to keep a temperature of the samples below a predefined temperature when heating the sealing cover. It further relates to a method for automatically sealing a microplate in which the thermally fusible sealing cover is disposed over the microplate, the sealing cover is heated to thermally fix it to the microplate and the microplate is actively cooled in a manner that a temperature of the liquid reaction mixtures is kept below a predefined temperature when heating the sealing cover.
Tube sealer
A device for sealing sample tubes comprises a tool assembly configured to interface with a rack (10) holding a plurality of sample storage tubes (20), the tool assembly holding a plurality of punches (322) and a die plate (324) including a plurality of cutting holes, with each of the plurality of cutting holes accepting one of the plurality of punches (322). The tool assembly receives a foil sheet (131) between the punches (322) and the die plate (324). The device includes an actuator enabling linear movement of the tool assembly. Linear movement of the tool assembly towards the rack (10) engages the die plate (324) against the rack (10) and punches the punches (322) through the cutting holes of the die plate (324) to punch a plurality of sealing sections from the foil sheet (131) and to press and seal each of the sealing sections against a top end of each of the plurality of sample storage tubes (20) in the rack (10).
METHOD FOR DETERMINING WHETHER A SEALING AREA OF A PRIMARY PACKAGING CONTAINER FOR AN OPHTHALMIC LENS IS UNACCEPTABLE FOR PROPERLY SEALING A FOIL THERETO
A method for determining whether a sealing area (13) of a primary packaging container (1) for an ophthalmic lens is unacceptable for properly sealing a foil to the sealing area (13) comprises the steps of taking an infrared image (7) of the primary packaging container (1); determining in the infrared image (7) a plurality of individual pixels (700-709) which are arranged along an area (73) corresponding to the sealing area (13) of the primary packaging container (1); determining from the infrared image (7) the temperature (T.sub.0, T.sub.1, T.sub.2) of the individual pixels (700-709), and determining that the sealing area (13) is unacceptable in case the following conditions are fulfilled: a) the temperature (T.sub.1) of each individual pixel of a predetermined number of coherently arranged individual pixels (700, 703, 706) is lower than a reference temperature (T.sub.0), and b) the difference between the temperature (T.sub.1) of each individual pixel (700; 703; 706) of the coherently arranged pixels (700, 703, 706) and the reference temperature (T.sub.0) exceeds a predetermined threshold.
APPARATUS FOR MANUFACTURING A CONTAINER
An apparatus for manufacturing a container that includes a side wall (5) in the form of a tube and a base (7) at one end of the tube. The apparatus includes a tube forming unit (15) for progressively folding a length of a sheet (19) of a side wall material into an elongate tube shape (21) having a forward end (23) for receiving a base (7) of the container and welding together lengthwise extending sides of the sheet to form the tube. The apparatus also includes a base attachment unit (17) for positioning a base of the container on the forward end of the tube.
SYSTEMS AND METHODS FOR MULTI-STAGE SEALING OF CONTACT LENS PACKAGING
A contact lens package includes a first package layer, a second package layer, a lens receiving area defined between the first and second package layers, and first and second seal portions. The first seal portion extends around a first portion of the lens receiving area. The second seal portion extends around a second portion of the lens receiving area. The second seal portion has different sealing properties than the first seal portion. The first seal portion may include a releasable seal between the first and second package layers, and the second seal portion may include a permanent seal between the first and second package layers.
Packaging machine having moisture sensor
A packaging machine, comprising a control unit, at least one measurement device and a plurality of work units for different processes. One of the work units is designed as a sealing station which comprises at least one moisture sensor designed as the measurement device which is functionally connected to the control unit and is designed to detect moisture within the sealing station as a time-dependent measured variable during a program sequence of the sealing station. The program sequence may comprise an evacuation process, wherein the control unit is designed to calculate a rate of change in the moisture during the evacuation process of the sealing station. The control unit may abort the evacuation process performed on the sealing station, based on the rate of change, before reaching a target vacuum pressure within the sealing station, immediately or after a specified delay time elapses.
Multi-layer injection molded container
A method for manufacturing an injection molded container includes operating an injection molding apparatus to inject one or more polymeric materials into a mold cavity to form a container. The container includes an energy director ring protruding from an inside surface of the container and extending circumferentially along the inside surface. The method includes welding a filter onto the inside surface by applying a welding force to the inside surface. The energy director ring causes the welding force to be concentrated at a location of the energy director ring, thereby forming a circumferential weld that secures the filter to the inside surface the location of the energy director ring.
FILING SYSTEM AND METHODS FOR ASEPTIC CARTRIDGE AND DISPENSER ARRANGEMENT
A package for use with a beneficial agent delivery device. The package includes at least one filling chamber having a sealed penetrable access region, at least one compartment configured to hold a content, wherein the content includes at least one of a beneficial agent or a constituent of a beneficial agent, and at least one channel connecting the at least one filling chamber in fluid communication with the at least one compartment. At least a portion of the package is resealable to contain the content.
METHOD FOR PRODUCING A PORTION UNIT OF A DETERGENT
A method for producing a portion unit of a detergent by inserting a base element made from a first film portion into a deep-drawing mold that forms a holding volume from the first film portion, the holding volume having a plurality of chambers spaced apart from one another; pouring at least one detergent composition into the chambers; placing a cover element made from a second film portion onto the filled chambers; connecting the cover element to the base element, which forms a film wrapping, sealing seams being formed between adjacent wall portions of the chambers; removing the portion unit from the deep-drawing mold, wherein the outside of the film wrapping is then wetted at least in the region of the adjacent wall portions and, by pressure being exerted, the sealing seams are compressed and the adjacent wall portions are brought into contact with one another and interconnected.
Removable cap with seal designed to be opened by piercing in a diagnostic analyzer
Embodiments are directed to a removable cap with a conduction seal closure for sealing an opening of a container. The cap has a side wall and a top wall with an open access hole there-through. A flat upper portion surrounds the open access hole, which is sealed by the conduction seal. The conduction seal comprises a first polymer sealing layer, an aluminum foil layer on top of the first layer to heat seal the first layer to the cap, and a second polymer layer arranged on top of the aluminum foil layer for protection. The aluminum foil provides a formable shaping strength such that upon seal piercing, a permanent memory spread of the first and third layers is achieved. Removal of the cap does not damage the seal. Access to the container contents is achieved without probe contact to the as-pierced seal.
