The Ideal System for Taring and Weighing of Vials


(click to download brochure)

Taris is a low cost system for taring and weighing of vials with the option of decapping and capping. The system is designed for batches of 100 to 200 vials per loading. The processing time is about 1 minute per vial (including screwing the caps off and on again). The system can run completely unattended. It produces a file with the weights and a log file of the complete run. An optional barcode reader can check the barcode while the vials are decapped and capped.

TARIS is a PC-controlled X-Y-Z distributor with a gripper arm for the transportation of vials and caps. Tray after tray of containers with the same dimensions can be weighed simply by pressing a button. Any number of rack formats for different sizes of bottles and ampoules can be stored permanently in TARIS' database. Different bottle arrangements, regular or honeycomb can also be accommodated in the software, multiple racks of the same layout can be processed in a single run. TARIS is easy to use. Once the layout of a rack has been stored in the database, the user just recalls the rack type, types in the number of vials to be tared, and starts the method by a key stroke. Containers of any height up to 70 mm can be handled. A universal tray is available for TARIS with two sliders to push the vials into arrays. Any standard packing tray or rack may also be used provided the bottles are held symmetrically and the necks are within the gripping.


As an option the TARIS can be connected to a unique microprocessor controlled single channel peristaltic pump Perifill®IQ 3000, ideal for the repeat delivery of liquids. With its continuously running 2-speed pump recycling system, the Perifill® IQ 3000 is designed to accurately dispense many types of liquid. Even hot and viscous fluids are handled with ease. The recycling system maintains flow rate and aids temperature control of the fluid ensuring consistent and accurate dispensing. The liquid being dispensed only contacts the tubing set, which can be sterilised by autoclaving. The Perifill is therefore ideal for use in bacteriological and pharmaceutical applications. Tubing sets can be changed in seconds. Silicone tubing sets will suit most applications. The minimum dispense volume can be reduced to 0.1ml by using the new 1mm bore silicone tubing set.


In the standard configuration TARIS is equipped with a 4-digit balance. Different weighing resolutions are available on request. The vials are transported to and from the balance by the gripper. In case of static charge a deionization unit can be integrated.

Vial Tracking

High resolution CCD barcode reading including 2D barcode reading of tubes (also Micronic and Matrix tubes), allows you to track and store information relating to your samples.

Capping and decapping

Screw necked vials with a thread of 12-28mm can be automatically capped and decapped with cap storage provided on the workbench. This is the ideal tool to minimize the exposure of highly reactive reagents.

The following vial sizes can be used with the TARIS:

Vial Size, ml Cap Diameter, mm Vial Height, mm Type
0.5 14 40 HDPE
5 18 47 Glass
5 22 49 HDPE
10 20 61 HDPE
20 24 69 HDPE
50 25 85 HDPE
100 25 107 HDPE
