Test tube matching

The heating block of each aperture corresponds to a test tube of a diameter, tailored to suit, and has excellent heating effect. It is best if one test tube is equipped with one heating block, and different heating blocks are replaced when different test tubes are used.

The same test tube holder can hold multiple test tubes smaller than the aperture, and the heating effect is also excellent.

Small sample size

Dry heating is the first choice, and the aperture can be customized to the test tube to ensure the accuracy of the heating temperature

Generally, centrifuge test tubes are used for small sample volumes, especially those with a sample volume of less than 2ml. Due to buoyancy, the test tubes are likely to float, which may cause water influx and contamination of the sample.

Visibility

general

Since water is used as the medium, the sample concentration process can be observed throughout.
