Unstirred Water Bath (NB 9/20)

Unstirred Water Bath (NB 9/20)

Apparently simple, NB series of unstirred water baths is nevertheless controlled by N-Prime™ microprocessor system giving excellent temperature precision, assisted by the triple insulation, for this class of instrument. N-Prime™ control system guarantees accurate temperature control and keeps samples at set temperature. Operated programs can be transferred to memory stick through USB port for traceability.

Most of the footprint of the water bath is usable to accept samples, since there is no pump, circulator or heater inside the chamber. A convenient drain permits fast discharge of the water. Their large displays are easily visible from across the laboratory.

Designed for many general and special applications in microbiology, research and industrial laboratories.
