With typical bead dispensing applications beads are poured from a bottle or tweezers or spoons are used to fill vials and wells with beads.  These processes are inefficient and very time-consuming.  LabTie has created an innovative tool that completely solves the tedious problem of dispensing your own beads.



Each dispenser is designed, produced, and tested by LabTie.  These dispensers are used all over the world in research laboratories, universities, pharmaceutical and biochemical laboratories, and institutes.  With its modular design, the mesh plates can be interchanged allowing the dispenser to be used to dispense multiple types and amounts of beads.  The dispensers work equally well dispensing various volumes of small diameter beads or dispensing just a couple larger diameter beads.  They can be used in conjunction with our tough Porvair microplates to load a small number of steel beads; perfect for high-throughput homogenizing of tough sample materials.  For those working with vials, the dispensers can be used with our 2.0 ml vial blocks allowing one to fill 45 microvials at a time.  Custom dispensers designed to your specifications are also available as well as dispensers designed to depositing various types of seeds.



The biggest value the LabTie Bead Dispenser offers is the huge time saving over other loading methods, up to 60 times or greater.  By reducing costs and errors, researchers can focus on what really matters.
