for test tubeslaboratory test tubewith thermostat

Description
TDB-120 is a Biosan dry block thermostat designed for laboratory sample temperature control. It maintains a constant temperature of tubes inserted into aluminium block sockets, providing high precision and uniformity across the block. The unit is widely used for PCR and other routine laboratory heating procedures.

Control and display

• Microprocessor-controlled temperature and time
• Simultaneous indication of set and actual temperature and time
• Digital time setting: 1 minute–96 hours or continuous (1 min increment)
• Timer audible signal
• Display: LCD, 2×16 characters

Built-in blocks (two models)

• Block A-103: 21 × 0.5 ml + 32 × 1.5 ml + 52 × 0.2 ml microtubes
• Block A-53: 21 × 0.5 ml + 32 × 1.5 ml microtubes

Additional information

• Blocks are fixed in the unit to ensure high temperature uniformity, stability and accuracy; users cannot change blocks themselves
• Reflective metal plate in the lid prevents condensation on tube caps
