Definitions

  • the invention relates to a refill unit with pipette tips for an autoclavable container.
  • autoclavable containers are known with a perforated plate in which a number of pipette tips are held in such a way that they can be removed by simply putting them on the pipette without touching them by hand.
  • the containers come onto the market filled with pipette tips. If the supply of pipette tips has been used up, it is possible to refill the perforated plate of the container with pipette tips, which are sold loose in bags.
  • this process is labor-intensive and time-consuming, so that in practice the Container is often thrown away as soon as it is empty, although multiple autoclaving of the container would be easily possible. Since pipette tips are widely used as disposable items in a wide variety of laboratories, the one-time use of the container can be seen as a waste of material on a large scale. The disposal effort and the environmental impact of the plastic containers are high.
  • the perforated plate is connected in one piece to the container walls.
  • the perforated plate is a part which can be detached from the container, but which should only be removed when the container is no longer used for pipette tips and is used for another purpose .
  • the object of the invention is to provide a refill unit of the type mentioned which is suitable for pipette tips in various standard sizes, the use of which results in a material saving and better material utilization, a simplification of disposal with less pollution of the environment and generally a reduction in costs.
  • a refill unit which consists of a folding box which receives and preferably carries a perforated plate made of autoclavable material to be equipped with pipette tips, the openings serving to receive the pipette tips being stepped in the perforated plate.
  • perforated plates equipped with pipette tips are provided as refill units for an autoclavable container, which can also contain a perforated plate equipped with pipette tips as initial equipment. If it is empty, it is exchanged for a new perforated plate supplied with it, so that the container remains in operation and, in the worst case, the perforated plate migrates into the waste.
  • the holder according to the invention with a folding box and a perforated plate carried by it forms a stable, stable unit. If it is not necessary to work in a sterile manner, pipette tips can also be removed directly from the holder by attaching them to the pipette.
  • the perforated plate has a flat plate body of essentially rectangular plan.
  • An edge web protrudes downward from the plate body and overlaps two opposite side walls of the essentially cuboid half-box on the outside. The perforated plate is thus securely fixed over the opening of the folding box.
  • the edge web is preferably designed all around. Since the edge web should lie along two side walls in the interior of the folding box, lateral slots are provided in the upper corner region of the side walls of the folding box over which the edge web extends, into which slots the edge web fits.
  • the perforated plate can be stiffened with ribs, which preferably extend in a check pattern parallel to the sides of the perforated plate.
  • the side walls of the folding box overlapped by the edge web are provided with slots extending from the upper edge, into which the ribs fit. The engagement of the edge webs or ribs in the slots contributes to the correct positioning of the perforated plate on the folding box.
  • the slots preferably have a bevel which facilitates the placement of the perforated plate on the folding box.
  • the bottom of the folding box can be open. This saves material.
  • the folding box can have a hinged lid which is preferably divided by a perforation and spans the perforated plate at a distance. Thanks to the perforation, the hinged lid can easily be torn off so that the pipette tips are fully accessible.
  • the hinged lid preferably has a tab that can be inserted between the perforated plate and a side wall of the folding box protrudes downward over the edge web of the perforated plate and is stepped at its side edge to form a stop which limits the insertion depth of the flap and meets the bottom of the side slots in the folding box.
  • the flap is held securely in the closed state by the tab.
  • the limit stop for the tongue insertion depth is particularly user-friendly.
  • An open finger recess can be provided in the side wall of the folding box lying in front of the flap.
  • the tab is therefore easily accessible for opening.
  • the perforated plate equipped with pipette tips is not necessarily stable itself.
  • a folding box of the type described forms a sufficiently stable support for the perforated plate, from which it can be removed if necessary and converted into an autoclavable container which also supports it perfectly.
  • the perforated plate is firmly connected to a base frame which carries the plate body and which consists of an autoclavable material.
  • a stand for pipette tips that is suitable as a refill unit for an autoclavable container is thus created, which is supplied with pipette tips and is delivered in a folding box and also forms a stable unit outside the folding box and the autoclavable container.
  • the base frame and the perforated plate are made in one piece Manufactured plastic, in particular by injection molding from polypropylene or polycarbonate.
  • the perforated plate should protrude laterally beyond the base frame over at least part of its circumference. This arrangement makes it possible to place the perforated plate on a web on the container walls when the stand is inserted into an autoclavable container.
  • the stand thus has a secure hold in the container, and its feet can lie at a distance from the container base, which is preferred for perfect sterilization.
  • One or more latching elements in particular in the form of knobs, grooves or the like, can be formed on the side wall of the perforated plate and cooperate with complementary latching elements on the walls of the autoclavable container.
  • corresponding locking elements are formed solely on the walls of the autoclavable container.
  • One or more upstanding tabs can be formed in the edge region of the perforated plate. These tabs serve as a convenient handle when a perforated plate is to be removed for replacement from the autoclavable container.
  • the base frame can consist of four feet at the corners of the perforated plate. This ensures a very stable structure with low material requirements.
  • the perforated plate can have conically tapering openings.
  • the taper of the openings makes it easier to shape the perforated plate during its manufacture.
  • At least some of the openings can be delimited from below on the conical projections formed on the perforated plate. This design is characterized by low manufacturing costs and good material utilization.
  • the feet of the stand can start around the openings located at the corners of the perforated plate and have a cavity suitable for receiving a pipette tip. This gives you a shape that is favorable for plastic injection molding technology with maximum display of the feet and full utilization of the perforated grid in the perforated plate.
