Typical Specifications

Typical block capacity

This class of dry block heater commonly accommodates 1 to 4 interchangeable blocks, each designed for various tube or plate formats.

Temperature range

Units of this type typically offer a temperature range from ambient +5°C to 100°C or 130°C.

Temperature stability

For this equipment class, temperature stability is commonly ±0.1°C to ±0.5°C.

Temperature uniformity

Uniformity across the block is typically ±0.1°C to ±0.5°C at 37°C.

Power supply

Commonly operates on a standard laboratory power supply, typically 230V, 50/60Hz, drawing around 150-300W.

Heating rate

Units typically heat from 20°C to 100°C in approximately 10-20 minutes, depending on the block and load.

Footprint

For a two-block unit, the footprint is typically compact, often around 200mm x 250mm x 100mm (W x D x H).
