Introduction
Techne® Dri-Block® heaters have been providing a safe, dry, constant temperature source in the laboratory for 50 years, offering market-leading choice, flexibility and specification. Dri-Block® heaters are a source of precision temperature control for general, routing applications and sensitive analytical procedures particularly suited to microbiology and clinical laboratories. They are designed for precise heating of test-tubes, microcentrifuge tubes, cuvettes and microtitre plates. Techne® Dri-Block® heaters cover the temperature range from ambient +5°C to 100°C or 200°C (depending on model) using machined aluminium alloy Dri-Block® inserts as the heat transfer medium. Independent indicator lights indicate mains power, heater action and over-temperature cut-out. An On/Off switch is mounted on the rear panel, together with the mains connector and a fuse holder.
Key Features
• Small, light, compact footprint - flat top surface allows units to be stacked in storage.
• Can hold any combination of aluminium insert blocks, depending on the model chosen.
• High quality, precision-engineered aluminium blocks provide excellent thermal contact.
• Versatile range of interchangeable heating blocks to fit all popular sample tubes and plates.
DB-3
• The DB-3 is designed to hold up to 3 aluminium insert blocks or one 96-well plate block.
• Temperature setting is by a calibrated dial.
• Temperature range from ambient to 100°C.
• Fast heat-up rate: 30°C to 100°C in just 18 minutes.
• Temperature stability at 40°C: ± 0.05°C.
Electrical Safety
The Dri-Block® range has been designed to comply with all RF interference and electrical safety regulations.
