The attaching position of a first flange is individually adjusted. A connection mechanism 10 includes two connection parts 11. Each connection part 11 includes a first flange 12 having a through hole 12a and an attaching portion 15 by which the first flange 12 is attached to a partial wall portion 1a1a while the through hole 12a faces an opening 1b. The attaching portion 15 includes: a vertical adjuster 60 which adjusts the attaching position of the first flange 12 so that a surface 12c of the first flange 12, which is opposite to a surface of the first flange 12 facing the partial wall portion 1a1a, to be vertical; and a rotation adjuster 80 which adjusts the attaching position of the first flange 12 about a horizontal axis H passing the center of the through hole 12a and extending in the thickness direction.

A sealed container includes a container body having an opening, a lid removably installed in the opening of the container body, and a first seal member installed to seal a gap between the container body and the lid. A locking hole is formed in an inner peripheral portion of the container body. A first opening capable of facing the locking hole is formed in an outer peripheral portion of the lid. A second opening communicating with the first opening is formed in an end portion of the lid. The lid includes a locking member that can linearly move to protrude from and retract into the first opening, a rotatable rotary member positioned to face the second opening, a conversion mechanism configured to covert rotational motion of the rotary member to linear motion of the locking member, and a second seal member installed to seal the second opening.
摘要:
The present disclosure provides a device that includes a base comprising a substrate having a first major surface, a pressure sensitive adhesive adhered to at least a portion of the first major surface, a polymeric cover film coupled to the substrate via the adhesive, a plurality of isolated closed compartments disposed between the substrate and the cover film, and an aqueous liquid disposed in two or more of the closed compartments. The cover film is a composite film comprising ethylene vinyl acetate copolymer, a linear copolymer of ethylene and a higher alkene, and a tackifier. Each compartment of the plurality is defined by a seal that prevents liquid communication with at least one other compartment of the plurality. Methods of using the device for partitioning a sample, for analyzing a sample, and for culturing a microorganism are also provided.
摘要:
The invention generally provides devices and methods for sampling, detecting and/or characterizing particles, for example, via collection, growth and analysis of viable biological particles such as microorganisms. Devices and methods of the invention include particle samplers and impactors for collecting and/or analyzing biological particles in manufacturing environments requiring low levels of particles, such as cleanroom environments for electronics manufacturing and aseptic environments for manufacturing pharmaceutical and biological products, such as sterile medicinal products. Devices and methods of the invention incorporate an integrated sampler and impact surface, such as the receiving surface of a growth media, in a manner to minimize, or entirely eliminate, risks associated with user handling, such as the occurrence of false positive determinations due to contamination of the impact surface during particle sampling, growth or analysis processes.
摘要:
An automatic culture system includes a transfer part configured to transfer a first airtight container which accommodates cells in a sealed state, and an automatic culture device configured to receive the first airtight container transferred by the transfer part, take out the cells from the first airtight container and culture the taken-out cells. The automatic culture device is configured to automatically perform replacement of a culture medium.
摘要:
Disclosed herein are apparatuses and methods for installing a sterilized peripheral in a bio-processing vessel. One aspect is an aseptic peripheral connection assembly for installing a sterilized peripheral in a bio-processing vessel via an aseptic connector affixed to the vessel. The aseptic peripheral connection assembly may include a carrier, an applicator, a plunger, and a removable hermetic sealing tab.
