Quantos Basic Model Powder Dosing (QB5). Reduce Errors with Perfect Concentration preparation. To prepare a solution, powder and liquids are dispensed automatically. Gravimetric sample preparation ensures the highest level of reproducibility; errors are reduced  by up to 60%. Achieve concentrations as low as 0.01 mg/g (according to GxP).

Maximum Safety

A closed container together with handsfree
weighing and sample handling minimizes operator
exposure to hazardous and toxic substances.
The substance name, lot ID, quantity, expiry date, etc. are stored on the RFID chip and traced for data output.

Cost Efficient

Gravimetric sample preparation eliminates the restriction of volumetric flask sizes. Smaller volumes of solution can be prepared, less solvent is consumed, and there is less waste to dispose. Automated weighing reduces the minimum sample weight of your balance by up to 30%.

Automated Powder Dispensing

Quantos is ideal for weighing fine, fluffy, static, compacted, granular, and heterogeneous substances. We’ve tested thousands of substances to become experts in automated powder weighing. Each head is our response to a specific problem / application.
