What are the advantages of a dry block heater over a water bath?

Dry block heaters offer precise temperature control, eliminate the need for water or oil, and reduce the risk of contamination. They are also generally cleaner and require less maintenance.

Can I use different tube sizes with this unit?

The QBT1 model is designed for specific tube formats, typically 1.5ml tubes with the included block. To accommodate different tube sizes, you would typically need to acquire compatible interchangeable heating blocks.

Is this unit suitable for continuous operation?

Yes, dry block heaters of this type are generally designed for continuous, stable temperature maintenance required for many laboratory protocols.

What maintenance is typically required for a dry block heater?

Maintenance is generally minimal, primarily involving keeping the unit and heating blocks clean. Regular visual inspection for any damage is also recommended.

Does this unit require calibration?

While these units are factory calibrated, regular calibration checks are good practice in a laboratory setting to ensure continued accuracy, especially for critical applications.
