Cole Palmer - Cole Parmer Techne Blockice Cooling Heating Block

• Maintaining biological samples at precise temperatures for enzyme reactions or cell culture.
• Incubating reagents for molecular biology techniques such as PCR or restriction digests.
• Cooling samples to prevent degradation during preparation or storage.
• Heating samples for denaturation or other temperature-dependent processes.
• General laboratory use requiring stable and uniform temperature control for small sample volumes.

Temperature range

Typically 0 °C to 40 °C, with some units capable of broader ranges.

Temperature stability

Commonly ±0.2 °C for this class of equipment, ensuring precise control.

Block capacity

Typically accommodates two standard interchangeable aluminium insert blocks, or one double-width insert.

Power supply

Units of this type commonly operate on 100–230 V AC, 50/60 Hz.

Footprint

For this class of benchtop equipment, a compact footprint is typical, often around 190 mm × 240 mm × 225 mm.

Timer functionality

Many units feature an integrated count-up/count-down timer, programmable for extended periods.

Display

A five-digit LED display in °C or °F is commonly found on units of this type.

Cooling/Heating technology

Peltier-based cooling and heating is typical for precise temperature control in this range.

• What types of sample tubes can be used with this unit?

  This unit typically uses interchangeable aluminium insert blocks designed to hold various standard laboratory tubes, such as microcentrifuge tubes, PCR tubes, or cryovials. Buyers should confirm specific insert compatibility with the seller.

• How quickly can this unit reach its target temperature?

• Is this unit suitable for light-sensitive reagents?

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

• Can this unit be used for continuous operation?

• What is the benefit of Isotemp™ technology?

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.
