Definitions

  • the invention relates in particular to the Analytical chemistry used certain standard solutions and suitable bottle according to the preamble of Claim 1.
  • EP-A-0 518 191 is a hermetic tight bottle known for storing reference liquids serves.
  • a channel is provided as an opening. The channel does not serve as a recondensation zone.
  • Standard solutions for analytical chemistry are in sealed bottles or ampoules.
  • the disadvantage is that the plastic Closures of the known glass bottles when used usually leak over long periods of time. You can also store the standard solutions bottles in the freezer due to the different expansion coefficients loosen easily from glass and plastic. Further the problem of contamination of the solutions arises through the seal of the closure.
  • the invention has for its object a lockable Bottle, especially for standard solutions, to create that is universally applicable and in solutions filled in before and also during removal protects against evaporation losses and contamination.
  • the bottle according to the invention is a capillary Channel in the upper part of the bottle body is provided, filled and emptied.
  • the capillary in Bottleneck acts as a recondensation zone and reduces evaporating solvent, even then, when the cap is removed from the bottle is. It also decreases due to the fine, elongated Narrowing in the bottle neck the danger of Contamination of the solution due to the material of the seal the cap. After removing the cap, you can the solution through the capillary channel with suitable Easily remove tools.
  • the capillary channel is advantageously in one provided substantially cylindrical piece that itself in the upper part of the bottle body, i.e. in the Area of the bottle neck, forming a circumferential Gap between the jacket of the cylindrical Piece and the wall of the tubular body is located.
  • the piece is expediently a one-piece component of the bottle body, so that between the wall of the tubular body on the one hand and the capillary containing piece on the other hand no leaks may occur.
  • the upper end of the tube piece is preferably formed Bottle body with external thread for screwing on the one containing a corresponding internal thread Provide sealing cap.
  • the contact pressure of the sealing insert is in the invention Bottle so big that the cap when storing the bottle in the freezer do not loosen or noticeably loosen the bottle cannot leak.
  • the bottle according to the invention essentially has one cylindrical body in which there is a closed Chamber for receiving the solution or liquid located.
  • the one related to the chamber capillary channel extends through the upper part of the cylindrical body, which is solid can be.
  • the capillary-shaped channel opens advantageously in a projection that is at the top of the Bottle body is provided.
  • the bottom of the bottle body is advantageously V-shaped. In the V-shaped recess remnants of the filled liquid collect, so that the bottle is using a chromatography suitable syringe or the like completely can be emptied.
  • the upper part of the bottle body be tapered or reduced in size.
  • Fig. 1 shows the closable bottle for standard solutions in a sectional view.
  • the bottle is there from a bottle body 1 and the bottle body sealing cap 16.
  • the bottle body 1 has a tubular one on it Bottom closed glass body 2 with an im substantially smooth outer wall 3.
  • the top half of the tubular glass body 2 takes one essentially cylindrical piece 4 on, the one-piece component of the tubular glass body 2.
  • the piece 4 has a circumferential web 5 at its lower end, molded onto the wall 6 of the tubular glass body 2 is.
  • the outer diameter of the cylindrical piece 4 is smaller than the inside diameter of the tubular glass body 1, so that in the area of the bottle neck 7 between the jacket 8 of the piece 4 and the wall 6 of the tubular glass body 2 there is an annular gap 9.
  • the piece 4 contains one extending in the longitudinal direction capillary channel 10 that connects to the interior 11 of the bottle body is connected.
  • the upper end 12 of the cylindrical piece 4 protrudes beyond the upper outer edge of the bottle body 1 also.
  • the bottom 13 of the bottle body 1 is V-shaped.
  • the V-shaped recess 14 can Collect liquid residue so that the bottle without having to tip them, using a pipette or a Chromatography syringe completely emptied from above can be.
  • the plastic cap 16 has a corresponding internal thread 17 and includes a seal insert 18 which is cylindrical Recess of the cap inserted is.
  • a seal insert 18 which is cylindrical Recess of the cap inserted is.
