Chemspeed's solution
The preparation of NMR and / or LC-MS samples is often still done manually and binds highly qualified resources to very time-consuming, tedious and error-prone tasks.
The SWILE technology enables automated true one-to-one gravimetric "pick & decision dispense" of solid compounds directly from sour vials. 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 automated 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 powder prior to pick-up.

- Dispensing range from 100's μg to about 5 mg with +/- 10 μg resolution with additional on-deck balance
- No cross-contamination
- No dead volume
- Fully inert (glass)
- Unattended operation
