Chemspeed's solution
Solid compound distribution into the formulation screening plates is often still done manually and binds highly qualified resources to very time-consuming, tedious, and error-prone tasks and fractional compositional mapping of ingredients in the μg / mg range are simply not achievable. Fractional compositional mapping is pivotal for performance and robustness in e.g. cathode materials, optoelectronics.
The SWILE technology provides fully automated true one-to-one gravimetric "pick & decision dispense" of compounds from μg to mg. The scheme at the bottom of this page displays the simplified SWILE workflow including the precision "pick & decision dispense" step. The technology backbone is based on Chemspeed’s proprietary overhead gravimetric dispensing tool design in combination with a second analytical on-deck-balance.
In order to exclude any risk of cross-contamination disposable glass tips are used which are stored and provided by the SWIN dispenser. The SWINs are available in different sizes (diameter) and can be adjusted according to the desired target amount to be dispensed. Additionally, a tilt / shake rack is used to loosening up and tilting the solid prior to pick-up.
- Revolutionary accuracy & precision due to decision dispensing
- Dispensing range from <100 μg to about 5 mg with +/- 10 μg resolution
- No cross-contamination
- No dead volume
- Unattended operation
