Electrically Operated Dispensers
Volumetric dispenser with a programmable volume in the interval of 10 to 1100 ml. The volume may be repeated to pump several liters in portions. This function may be used for instance to repeatedly fill vessels.
On the picture is shown a product version with a stand. It may also be mounted on a stainless lab trolley or with the lower part under a table.
All parts in liquid contact are corrosion resistant, allowing handling of aggressive liquids and solvents. It is also available for dilution purposes with extra valves.
Easy to operate via touch panel. No PC is needed. Just type in the desired volume in ml and the dispenser will withdraw the volume from the container and dispense it from the outlet.
Different liquids will need different withdrawal and infusion (dispensing) speeds which is easily changed through the panel.
Exact dosage of liquid volumes is in the range of < 10 – 1100 ml. The set volume can be repeated, thus it is also possible to dispense for instance 999 x 1100 ml.
Standard deviation less than 0.02.
Volume accuracy and precision: fault < 0.5 ml in the interval 30 – 300 ml and in the interval 300 – 1100 ml < 0.4%.
The concept can be made in other configurations, such as compact models with shorter but broader cylinders, when a slighty less accurate delivery is acceptable. Lower volume ranges, e.g., 500 ml are also available.
Other and Models
We also produce smaller dispensers for volumes from 1ml to 500 ml or according to customers´ choice.
The stroke volume, withdrawal and infusion speeds are fully programmable with possibilities to store standard programs that may be used without a computer.
It is possible to use the dispensers (if lubricated) with air or other gases for pumping/sucking. To simulate breathing patterns for humans and rodents refer to: Breathing Profile Generator F-SIG 6300
See below also our range of pneumatically driven dispensers, which can also be made ATEX rated.
Pneumatically Operated Dispensers for Automation
FIA’s Volumetric Dispensers are designed for dosing of an aqueous solution, in mix with solvents or for pure solvents (i.e. methanol, ethanol or heptane). The dispensers are designed for automation and can be free standing or mounted on a rail.
- Can be operated in a series
- Very accurate with a repeatability of 0.04% RSD
- Simplicity in design
- Long life time of dispensing equipment
- Constructed of glass and teflon
- Suitable for integration in robotic systems
- Can be ordered on a mobile platform for best working environment
- Full volume each stroke
- Impact time 10-20 sec
- No PLC nor computer dependent, but can be easily connected
The dispensed volume is fixed within an interval and can be calibrated. The ordered dispenser volume is one of:
- 0,05 – 0,15 ml
- 2 – 10 ml
- 10 – 25 ml
- 15 – 50 ml
- 25 – 100 ml
- 100 – 250 ml
- 800 – 1000 ml
All dispensers require compressed air of 6-8 bar.
Manually Operated Large Volumetric Dispensers
The larger volumetric dispensers operate with syringes from FIA. They have volumes up to 1000 ml. It is also possible to obtain the syringes for manual use.
