Definitions

  • the invention relates to a pipette for a pipette system with pipette and syringe, namely a pipette having the features of the preamble of claim 1.
  • Pipettes are devices for measuring and transferring liquids.
  • a pipette that allows a gradual release of a liquid wedge from a syringe (Repetierpipette).
  • a pipette is for example from the DE 199 63 141 A1 and the EP 1 110 612 A1 known.
  • liquid is taken up in the syringe used in the pipette housing of the pipette in one go. Then the pipette is moved to the place of application. At the point of use, the liquid taken up in the syringe is released step by step by repeated actuation of the actuating lever located on the pipette housing in previously set portions.
  • the repeating pipette known from practice has a piston adjusting device in the form of a rack and pawl combination.
  • the rack is made in one piece from an extremely dimensionally stable metal, especially brass, machined.
  • the cost of producing such a rack is relatively high in relation to the cost of the pipette as part of a large-scale production.
  • the teaching of the present invention is based on a pipette with a one-piece rack in such a piston adjusting device.
  • the rack is now made in several parts, namely at least two parts, preferably exactly two parts. It consists first of a carrier which has a receptacle for a toothing part. In or on the receptacle of the carrier sits the toothing part, which in turn has the toothing of the rack.
  • the carrier on the one hand and the toothing part on the other hand can be made of different materials.
  • the material of the carrier can be adapted to the local requirements.
  • the carrier must be dimensionally stable and the toothed part fixed securely and in the correct position in the piston adjusting device. It does not have to be very dimensionally stable and it does not have to fulfill the special requirements for finely imaged toothing.
  • the toothing part is highly dimensionally accurate to manufacture and must be highly precise executable especially in the teeth. This is usually a more expensive material to use.
  • the outer shape of the toothing part in particular what deflections or the like. does not have to be very precise, because here the carrier acts with its rigidity.
  • the toothing part may in particular be made relatively thin. Its spatial orientation and fixation experience it only in connection with serving as a stiff backbone wearer.
  • the toothing part consists of a high-quality, preferably fiber-reinforced plastic, in particular of a fiber-reinforced PEEK.
  • a plastic part can be manufactured as a series part with high precision and excellent dimensional stability and low shrinkage.
  • this toothing part is expediently made as small as possible in terms of volume, because the material used is relatively expensive.
  • the wearer can be quite voluminous and is designed so that it is as stiff as possible. Its dimensional accuracy in detail is less important.
  • the material to be used here can be significantly cheaper than the material of the toothing part.
  • Each of the two parts are assigned the tasks that best suit them.
  • the toothing part has a longitudinal contour, which is adapted to a longitudinal counter contour on the carrier so that a positive, preferably axially straight guide results, wherein , Preferably, the contour and the mating contour are formed as a T-slot guide. By this guide, the flat and usually relatively thin toothing part is aligned.
  • the dimensional accuracy of the toothing part can be further improved by the fact that the toothed part seen in cross section has at least one longitudinal stiffening web on the side opposite the toothing.
  • the filling behavior in the injection molding process in a plastic part is significantly smoother by such a bridge.
  • the toothing part including the toothing in cross section has a ratio of the width to the height greater than 1.5, preferably greater than 4.0. Over its length, such a relatively uniformly elongate toothing part hardly has a delay and only a relatively small deflection. Due to the low height in relation to the width, it can be aligned relatively easily when inserted into the carrier.
  • the toothing part can thus be optimized for the dimensional accuracy of the tooth pitch of the toothing, the deflection over the entire length of the toothing part may have less importance.
  • the teaching of the invention is of particular importance with a relatively small tooth pitch, tooth pitches below 1 mm can be produced in metal racks only with great effort.
  • a high-quality plastic injection molding technique can be according to the teachings of the invention, smaller tooth pitches to reach. Accordingly, it is recommended according to preferred teaching that the toothing has a pitch of less than 1.0 mm, preferably less than 0.6 mm. It is obvious that a smaller pitch allows a greater number of steps and possible sub-volumes.
  • the toothing in the case of the pipette according to the invention can also be optimized in the tooth form and in the tooth height. It is recommended that the toothing is sawtooth-shaped and the tooth angle between the tooth back and the tooth flank is between 25 ° and 45 °.
  • the teeth are very fine on both the gearing and the pawl.
  • the pawl which preferably consists of fiber-reinforced plastic, having a plurality of ratchet teeth, preferably three ratchet teeth.
  • the width of the pawl is greater than 4 mm, preferably greater than 5.5 mm.
  • the ratchet teeth of the pawl have the sawtooth shape of the toothing and that, preferably, the pitch of the ratchet teeth is less than the pitch of the toothing.
  • the ratchet teeth so fall even with appropriate inclination of the pawl in the teeth on the toothing part and achieve a safe, force-transmitting engagement.
  • the pipette housing which limits the movement of the pawl in the direction of the syringe.
  • a rigidly arranged stop is present on the pipette housing, which limits the movement of the pawl in the direction of the syringe.
  • Such a construction is also recommended in the case of the pipette according to the invention.
  • the toothing part has a stroke stop for the absorption of liquid in the syringe. The stroke stop ensures dimensional accuracy when engaging the first stroke to dispense liquid after previously taking up liquid in the syringe.
  • the rack has a cam which cooperates with the spool and with the piston advanced into the syringe raises the spool so that the pawl is dug out of the gearing.
  • the cam is mounted on the rack in the axial direction adjustable.
  • the cam is mounted in an adjustable manner in the axial direction on a sliding guide arranged on the carrier of the rack. It is particularly useful in this case then that the carrier of the rack is designed in one piece with this sliding guide.
  • the piston adjusting device typically has a receptacle for a piston head of a syringe. It is particularly useful then that the carrier of the rack is made in one piece with this recording
  • the carrier of the rack at the lower end is made in one piece with the receptacle of the piston adjusting device and integrally formed at the upper end in one piece with the sliding guide for the cam.
  • Fig. 1 shows the basic design of a pipette 1 according to the invention with an inserted syringe 2.
  • the syringe 2 has a cylinder 2.1 with a mounting portion 2.2, which is preferably designed as a flange, and with a piston which in Fig. 1 can not be seen because it is located in the pipette housing 3 of the pipette 1 shown there.
