Product overview

DOSASET is a dispenser for cyclohexanone or similar solvents, used for manual bonding of plastic medical equipment, tubes and joints.
DOSASET does not use porous elements or capillary holes or fluid pumps: its adapters are directly dipped in the solvent, reducing the problems due to clogging or obstruction.
DOSASET employs a new patented method, based on a rotating and vibrating system: the dispensing adapters are mounted on the circumference of a wheel turning inside a chamber where the solvent level is continuously controlled.
The solvent is kept inside a sealed external 250 ml bottle and is automatically loaded trough a pneumatic micro-pump from the bottle to the dispensing chamber.

 

 
Detailed introduction

DOSASET ADVANTAGES

No maintenance is required to prevent clogging and obstruction
Constant solvent dispensing, determined only by the shape of the tube adapter
Reduce evaporation of the solvent in the dispensing chamber
No wrist rotation, reduces the risk of carpal rotation syndrome
Automatic control the solvent level by shutoff valve if the level cannot restored
The vibration of the tube adapter compensates the tolerance of the tube diameter
Up to 4 tube adapter for different diameters on the same instrument
The sequence of the tube adapter can be programmed for the subassemblies with different tube diameter
Only one selected tube adapter available for each new adapter, which can reduce errors.
