Dry Block Nitrogen Evaporator - 12-Tube Sample Concentrator - RT+5 to 160°C - 15 L/min

The Master Science Dry Block Nitrogen Evaporator concentrates samples by blowing nitrogen onto tubes held in a high-purity aluminium heating block. Using a dry block instead of a water bath keeps the bench clean and gives fast, uniform heating up to 160 °C.

Twelve gas needles can each be opened or closed independently, and the needle manifold height adjusts steplessly with one hand to suit different tube lengths.

Key Benefits

• No water bath mess: the Master Science Dry Block Nitrogen Evaporator heats through aluminium, so there is no water to refill or contaminate.
• Save nitrogen: each needle can be shut off when fewer samples are loaded.
• Fast heating: reaches 160 °C in 15 minutes or less.
• Fits many tube sizes: interchangeable blocks cover 10 to 20 mm tubes.
• Compact footprint: small enough for crowded fume hoods.

Common Laboratory Problems and How This Evaporator Helps

How the Master Science Dry Block Nitrogen Evaporator improves sample concentration:

• Water bath contamination and refilling: dry block heating removes the bath entirely.
• Wasting gas on empty positions: needles switch off individually.
• Uneven tube temperatures: aluminium block heats uniformly.
• Different tube sizes: swap blocks to match the tubes.
• Slow warm-up: fast heating shortens preparation time.
