Atlas Volumetric Dosing - Syrris - Versatile Sampling System
Atlas Volumetric Dosing
The Atlas Syringe Pump is a versatile volumetric dosing and/or sampling system. It allows 2 independent refilling flows, one continuous flow, reaction sampling, intelligent control of pH and temperature dependant dosing. It consists of two syringes and multi port valves and can be controlled from the front panel, by the Reactor Master, an Atlas Base or PC software.
- Flexible: Use as 2 refilling pump channels or 1 continuous pump channel or an autosampler.
- Easy to use on its own: Twist and click control knob and large display.
- Automated reagent addition: Dispense simply by volume or flow rate over a time period or create advanced flow profiles.
- Versatile: 10 reagents to one reactor, 1 reagent to 10 reactors, 5 reagents to 2 reactors, one continuous flow, etc.
- Automated reaction sampling: Use with the Autosampler module to regularly aspirate samples into 2ml HPLC vials.
- Wide flow rate range: 0.5 l/min to 10ml/min (up to 100ml/min with the Atlas Syringe Pump XL)
- Intelligent: Pump to control pH or pause if a reaction temperature is exceeded. Full data logging to a csv file.
- Compact size: Fits conveniently alongside reactor. Excellent chemical compatibility: PTFE, PCTFE and glass.

Atlas Syringe Pump Features
The pump can be used on its own, connected to a Reactor Master, an Atlas Base or controlled by a PC. In all modes, the two syringes (with up to 6 port valves) can be configured into a variety of configurations. As each port can be used to aspirate from or dispense to, the pump can be used as “one to many”, “many to one”, an autosampler or one continuous flow.
The pump can be connected to Atlas pH or temperature sensors to allow control of pumping based on these values. When connected to a Reactor Master or an Atlas Base, reagents can be added automatically after a temperature and stirrer speed has been reached or paused in the case of an exotherm.
Examples of Operation
Specification and Parts
Specification
|
Working Volume Options: |
50ml, 100ml, 250ml, 500ml, 1 litre, 2 litres, 3 litres or 5 litres (vessels are interchangeable). Note that vessels greater than 2 litres also require the Remote Mount. |

2. |
|
Options for Syringe Sizes: |
50ul, 100ul, 250ul, 500ul, 1ml, 2.5ml, 5ml. |
|
Options for Number of Ports per Valve: |
2, 3, 4 or 6. |
|
Maximum Flow Rate in Continuous Mode: |
20% of syringe volume per minute (e.g. 10ul/min when using 50ul syringes) |
|
Maximum Flow Rate in Dual Dosing Mode: |
1% of syringe volume per minute (e.g. 0.5ul/min using a 50ul syringe) |
|
Maximum Flow Rate in Continuous Mode: |
400% of syringe volume (e.g. 20ml/min with 5ml). Note that much higher rates are possible with the Atlas Pressurized Input Store. |
|
Maximum Flow Rate in Dual Dosing Mode: |
400% of syringe volume (e.g. 20ml/min with 5ml). Note that much higher rates are possible with the Atlas Pressurized Input Store. |
|
Modes of Operation |
There are 5 main modes of operation (standalone modes shown by *) |
|
1) DUAL DOSING* |
Dose a volume, pump at a flow rate, dose one reagent to reactors or sophisticated profiles. Connect an Atlas Temperature Probe and Node to pause the addition if over/under temperature. |
|
2) PH CONTROL* |
Connect an Atlas pH Probe and Node to dose an acid and/or base to keep within a defined range. |
|
3) CONTINUOUS* |
2 syringe pumps work together to produce 1 continuous flow, i.e. one is refilling while the other is dispensing. |
|
4) ATLAS BASE CONTROL |
Atlas Syringe Pump can be controlled from the Base Unit as part of an automated temperature and stirrer speed profile. |
|
5) PC CONTROL |
PC software can control Dual Dosing and pH Control in the same way as the Atlas Syringe Pump. |
