  • a liquid tissue culture medium is placed through the access port into the receptacle chamber in contact with the base, the medium is incubated to allow the tissue culture to grow and to attach such growth to the base.
  • the liquid medium is then removed from the chamber, and the receptacle is removed from the base.
  • the tissue culture growth on the base can then be treated as desired and microscopically examined.
  • This apparatus is also useful as an anaerobic chamber or as a blood culture chamber for microbiological assays.
  • the prior art tissue cultures have been obtained in the following manner.
  • a known measured amount of liquid growth medium containing a suspension of the cells to be grown was placed in a sterilized glass test tube.
  • the tube was then sealed with a non-toxic stopper and placed on its side in an appropriate rack and oriented so that the area of cell attachment and growth was always immersed in a nutritional fluid environment.
  • the tube was then incubated until a complete cell monolayer was grown.
  • the tube was then examined microscopically to'check for growth and then again to check for any cytopathologic changes induced by any experimental treatment during such growth.
  • a second cell culture In order to obtain a permanent stained slide of any such cytopathologic changes which occurred during the above growth, a second cell culture must be prepared. A cleaned glass coverslip was placed in a specially modified glass tube and a portion of liquid growth medium containing a suspension of the cells to be grown was placed in the tube in contact with the coverslip. The tube was then sealed and incubated as described above to grow a cell monolayer on the coverslip. The same experimental treatment was repeated to effect the same cytopathologic changes. When the desired cell growth and changes were accomplished, the coverslip was removed from the tube, rinsed, fixed and stained. The stained coverslip was then mounted on a microscope slide for subsequent examination and storage.
  • microbiological chamber apparatus useful for carrying out biological reactions or growth therein, such as growing tissue cultures, which comprises in combination a base member and a cooperable receptacle having sidewalls, a top wall and an open bottom opposite from said top wall surrounded by a bottom surface, said bottom surface being removably mated in liquid-impermeable contact with said base, whereby said base member forms the bottom wall, said sidewalls of said receptacle form the sidewalls, and said top wall of said receptacle forms the closed top wall of said microbiological chamber apparatus, said receptacle having at least one scalable sidewall access port.

  • a box-like receptacle 14 is located near end face 17 and mates against surface 13 of base member 12 so as to leave a substantial portion 19 of surface 13 exposed near end face 15.
  • This free surface area 19 can be etched so as to render it capable of receiving appropriate identification markings, or an appropriate label can be atfixed to this free surface area.
  • Base member 12 is preferably a glass microscope slide when the microbiological reaction or growth chamber apparatus 10 is intended to be used for tissue culture.
  • Such microscope slide is preferably fabricated from soda glass which has been cleaned to remove oils, greases, surfactants, abrasives or other materials inhibitory to biological or bacterial growth.
  • Upper surface 13 of base member 12 must be reasonably fiat to form a mating surface for receptacle 14.
  • Glass microscope slides useful in the present invention are marketed by the Erie Scientific Co. under the designations 'ESCO No. 2955-1 or No. 3A. It is understood that other materials, such as sintered alumina, organoplastics and the like, can also be used for the base member 12 for biological reaction chamber apparatus of the present invention, providing such materials are appropriately cleaned and do not inhibit the desired biological reaction or growth.
  • Receptacle 14 is formed with a top wall 30, opposing longitudinal sidewalls 16 and 18 and opposing transverse sidewalls 20 and 22 defining an open bottom 21 therewithin at the base thereof. At its base, receptacle 14 is formed with a peripheral outwardly directed flange 24 surrounding the bottom opening 21. Flange 24 has a bottom surface 40 shown in FIG. 2, as well as end faces 26 and 28. The opposing sidewalls of receptacle 14, as shown in FIG. 1, are preferably inclined inwardly toward each other at an angle of about from the vertical.
  • One wall of recptacle 14, for example wall 20, is formed with an access port from which conduit 32 extends. Conduit 32 has external threads 34 which are capable of threadably mating with internal threads (not shown) of removable cap 36 for sealing the access port. Other suitable convenient means can also be used to removably seal the outer end of conduit 32.
  • Receptacle 14 also has an injection port formed by conduit 38 located in peripheral flange 24 near end face 28.
  • the internal passage 39 of conduit 38 extends through flange 24.
  • the bottom surface 40 of flange 24 is formed with a rectangular groove 42 which is in general alignment with the sidewalls 16, 18, 20 and 22 of the receptacle.
  • the internal passage 39 of conduit 38 communicates with groove 42 as shown.
  • Receptacle 14 is preferably formed from transparent organoplastic materials.
  • Useful organoplastic materials are polystyrene, polypropylene, celluloid, polymethacrylate, polymethylmethacrylate and the like.
  • the bottom surface 40 of receptacle 14 is mated against surface 13 of base member 12 near end face 17 and clamped thereto by suitable clamping means (not shown), the mating surfaces having been previously cleaned.
  • An adhesive gasket material in liquid or slurry form is then injected through passage 39 of conduit 38 to fill groove 42 with such material.
  • the gasket material is then allowed to solidify slowly at ambient temperature, or more rapidly under heating con ditions, to form an adhesive gasket 44 (shown in FIGS. 2 and 3) which provides a liquid-impermeable seal between the receptacle 14 and the base 12 at its points of contact therewith.
  • the clamping means can be removed, since the receptacle 14 is adhered to the base member 12 by means of the adhesive gasket 44.
  • the receptacle can be easily removed from the base by pulling it away from the base.
  • a preferred gasket material is an organopolysiloxane elastomer.
  • An especially useful gasket material is an organopolysiloxane elastomer composition marketed by the General Electric Co. under the designation 'RTV 630. This material is further described in US. Pat. No. 3,436,- 366. It is further preferred to remove entrapped air from the above RTV 630 material before it is used to form the gasket. This is conveniently accomplished by placing the material in a desiccator and evacuating it to a vacuum of about 10-15 in. of mercury for about 20-30 min.
  • useful gasket materials are microcrystalline waxes and various synthetic organic elastomers.
  • the principal criteria for a useful gasket are that it provide desired removably adhesive characteristics between the receptacle 14 and the base 12, provide a liquid-impermeable seal, be non-toxic to the biological material subsequently employed in the apparatus, and not act as a source of growth for undesirable microorganisms.
  • the microbiological chamber apparatus After fabrication of the microbiological chamber apparatus, it is then sterilized in any well-known manner, and the access port conduit 32 is then sealed with a sterile cap 36 or other means. The apparatus can then be stored until ready for use.
  • the previously sterilized microbiological chamber apparatus of the present invention is employed in the following manner to grow tissue cultures, for example.
  • the cap 36, or other sealing means, is removed from conduit 32.
  • the desired liquid tissue culture medium 46 (FIG. 3) containing a suspension of cells to be grown is then placed into the receptacle.
  • the adhesive gasket 44 forms a liquid-impermeable seal between the receptacle 14 and the base 12 to prevent any leakage from the apparatus.
  • Conduit 32 is then resealed by re placing cap 36, for example, in threaded engagement with threads 34.
  • Appropriate identification markings are then entered on the free surface area 19 of base 12 to describe the contents of the receptacle chamber.
  • the apparatus is then placed in a suitable incubator and is incubated under well-known conditions to carry out the tissue culture growth.
  • suitable treatment may be carried out on the cells and medium during this growth to achieve cytopathologic changes in the cells.
  • Various reactants can be introduced through conduit 32, and samples can be withdrawn through conduit 32.
  • a mass of tissue cells 48 is attached to base 12.
  • the tissue culture medium can then be removed from the chamber by aspiration, for example, through conduit 32, and the receptacle 14 is then removed from the base 12.
  • the mass of tissue cells attached to the base is then rinsed and fixed on the base, and the alfixed tissue culture is then treated with an appropriate stain to stain the culture.
  • the stained culture can then be microscopically examined, and the base 12 with the culture attached can be stored for further use.
  • This provides a permanent record of the results of the tissue culture growth which can be produced through use of the apparatus of the present invention in a far simpler and more eflicient manner than through the use of the techniques employed in the prior art.
