Definitions
- the invention relates to a piston burette for a burette arrangement with a burette cylinder which has an outflow opening at one end and in which a piston is slidably disposed.
- a burette is a calibrated scale with a reagent fillable transparent tube with an outlet for controlled dispensing of the reagent used in the dimensional analysis for the volumetric determination of substances.
- a special embodiment represent the piston burettes, mainly in analytical chemistry to determine unknown amounts of substances in samples using titrimetry or used in microbiology or genetic engineering. You hire high-precision work equipment, so that the geometric training of Piston burette, especially on the inside diameter of the burette cylinder, high demands are made.
- the reagent-filled glass tube is discharged Glass tube designed as a burette cylinder, in which to convey the Reagent a piston is slidably disposed. The dosed volume is measured and displayed by the displacement of the piston.
- FIG. 6 shows the principle of such a piston burette.

- the piston is retired - in any one Position between upper and lower end point as limits - are both Valves closed. The position of the valves is marked in Fig. 6.
- the suction valve 1 When used in analytical chemistry, the suction valve 1 is over an intake hose 6 connected to a storage vessel 7 in which a Reagent of known composition and concentration is located.
- the Outlet valve 2 is via a metering hose 5 with a device in which Usually a titration tip connected above one (not shown) presentation vessel with the unknown solution (analysis vessel) located.
- the piston burette is fixed in the Burette arrangement integrated. You therefore need a burette cylinder Relatively complex valve system connected upstream via two openings, since the The correctness of the volume determination depends largely on the precision, with which the valve system works, in particular what possible leaks as well Dead volumes in the valve system affects. Crucial for the correctness and Accuracy of volume determination is also the high constancy of Inside diameter over the length of the burette cylinder. For this, in usually specially calibrated glass tubes are used, so-called precision diluters, in a hot forming process on a precise inner mandrel be shrunk on.
- the known burette cylinders made of glass are therefore In addition to the disadvantage of sensitivity to breakage, it is very expensive a multiple use with the need for a complex Cleaning procedure when changing the reagent.

Its hardness also prevents mechanical deformation of the burette cylinder when dosing.
- COC cycloolefin copolymers
- the need for the burette cylinder is eliminated Upstream valve system with a reservoir for the reagent, whereby also the burette cylinder no longer has an inlet opening, but only one Must have outlet opening for the pre-filled reagent.
- the pre-filled Burette cylinders can also be used as storage containers for the reagent to be used. Since the invention Piston burette simple and therefore quick, as well as safe on the The piston burette arrangement can be put on, the invention also ensures a quick and safe operation of the arrangement, as well as the conversion to another reagent.
- oxidation-sensitive reagents such as thiosulfate solutions, which are caused by Oxygen could be oxidized during storage
- plastics made of polyethylene naphthylate (PEN), Polyethylene terephalate (PET) or blends consist of it.
- the burette cylinder can also be multi-layered from different plastics be constructed.
- the burette cylinder can be used for Reduced frictional forces when moving the piston with a Lubricants such as silicone oil may be provided; this is already useful at the formation of the brush cylinder in the injection molding process with in Plastic mass introduced.
- Lubricants support in the case of In addition to the hard plastic COC, the goal of a mechanical To avoid deformation of the plastic buret cylinder what is still in the described DE 43 10 808 A 1 as a major disadvantage of the known Plastic dosing cylinder is shown.
- burette cylinder sealing cap consists in particular of an elastomer, preferably made of rubber such as halogenobutyl rubber, silicone elastomer or thermoplastic elastomers.
- the movable piston is preferably made of a rigid plastic, such as e.g. made of fluoropolymers, PTFE, ETFE, FEP or other plastics a low coefficient of friction and high chemical resistance.
