Twin-Block Nitrogen Evaporator - 24-Tube Sample Concentrator - RT+5 to 160°C - 500 W

The Master Science Twin-Block Nitrogen Evaporator doubles capacity with two aluminium heating blocks, allowing up to 24 tubes to be concentrated at once under a stream of nitrogen. Dry block heating replaces the water bath, giving clean, uniform and fast temperature control up to 160 °C.

Each needle can be opened or closed individually, and the manifold height adjusts steplessly with one hand, so partial batches and different tube lengths are handled easily.

Common Laboratory Problems and How This Evaporator Helps

How the Master Science Twin-Block Nitrogen Evaporator supports busy sample prep:

• Batches larger than 12 tubes: two blocks give 24 positions.
• Mixed tube formats: each block can hold a different size.
• Water bath upkeep: dry heating removes it.
• Gas wasted on empty spaces: needles close individually.
• Uneven evaporation: uniform block temperature keeps samples consistent.
