Which nitrogen concentrator type fits my sample preparation workflow — water bath, dry block, or automated endpoint?

Match the model to your sample count, solvent and required reproducibility.

• A water bath nitrogen concentrator gives uniform, gentle heating to 30–100 °C and is the most economical choice for routine batches of 12–60 samples in aqueous or common organic solvents.
• An enclosed dry block nitrogen evaporator needs no water, reaches higher temperatures, and suits small volumes, aggressive solvents and applications where cross-contamination must be avoided.
• An automated endpoint nitrogen evaporator uses sensor-based volume detection to stop each position at a preset volume — the best fit for regulated laboratories, trace analysis and any workflow that demands walk-away automation and batch-to-batch consistency.
