  • Patent number: 10451596
    Abstract: An automated sensor calibration system and method provide for calibrating a gas sensor in-situ in a controlled atmosphere workstation. The system comprises a controller for automatically controlling the calibration system; an enclosure member movable between a first position and a second position; and a drive mechanism, operable by the controller, for moving the enclosure member between the first position and the second position. In the first position, the enclosure member is arranged in a spaced relationship from the sensor such that a sensing head of the sensor is exposed to the controlled atmosphere of the workstation. In the second position, the enclosure member is arranged in engagement with at least one surface so as to define a calibration chamber and enclose the sensing head in the calibration chamber.

  • Publication number: 20190143379
    Abstract: A cleaning system for cleaning a stylus of an inoculation apparatus comprises a bath with a first washing trough to hold a first washing fluid and a first weir defining a first washing fluid level, a second washing trough to hold a second washing fluid and a second weir defining a second washing fluid level higher than the first washing fluid level so the stylus is immersible to a greater depth in the second washing fluid than in the first washing fluid. A third washing trough may hold a third washing fluid with a third weir defining a third washing fluid level higher than the first washing fluid level so the stylus is immersible to a greater depth in the third washing fluid than in the first washing fluid. An inoculation system may comprise the cleaning system and may employ an automated method of cleaning the stylus.

  • Patent number: 8695679
    Abstract: The invention relates to a user access port for a controlled atmosphere apparatus comprising a porthole extending through a wall; a sealing assembly comprising a first sealing means and a second sealing means for maintaining a sealing barrier across the porthole, whereby the first sealing means comprises a first closure member that is adapted to at least substantially seal the porthole when arranged in a closed position and allow user access to the porthole when arranged in an open position; the second sealing means is mounted so as to extend at least substantially across the porthole and comprises a sealed access member and a second closure member, whereby the sealed access member comprises a user access aperture having a peripheral edge adapted to form a sealing contact with an arm of a user when an operator extends his arm through the user access aperture and whereby the second closure member is adapted to at least substantially seal the user access aperture when arranged in a closed position and at least

  • Patent number: 5861305
    Abstract: The invention provides an exemplary anaerobic cabinet system which comprises as least one anaerobic cabinet which defines an enclosure interior of which is visible from outside of the cabinet. The cabinet includes a mechanism for inducing and maintaining a prescribe low oxygen internal atmosphere within the enclosure. The cabinet further includes at least one hand/arm access port, a controlled lock-type access mechanism for manually introducing and removing items through the port, and a hand/arm access port provision which is operably coupled to the lock-type access mechanism for manipulating items within the cabinet. The lock-type access mechanism comprises a door provision which in combination with the port provision define an import chamber for loading and/or unloading items to and from the enclosure through the port.
