• What types of reaction blocks are compatible with the Pierce Reacti-Therm 18840?

  The Reacti-Therm 18840 is designed to accept specific Pierce Reacti-Block aluminium inserts. Buyers should verify compatibility for their required tube or vial sizes directly with the seller.

• Is temperature calibration required for this unit?

• What maintenance is typically required for a dry block heater?

• Can this unit be used for cooling applications?

• What safety features are typically included?

Dry block heaters are valued in laboratory and biotech settings for reliable, uniform sample heating. Buyers typically appreciate their compact design, precise temperature control, and ease of use. When purchasing used units, checking calibration accuracy, element functionality, and power cord condition remains important. Industry sentiment favours models with consistent performance records and minimal maintenance history. Common strengths include rapid heat-up times, good temperature stability, and compatibility with standard microtubes and vials. Corrosion resistance in the heating block surface is often considered desirable for longevity.
