Digital dual block dry bath

Quick Answer: The Digital dual block dry bath is a benchtop dry block heater with two block positions, pictured with a separate digital display and buttons for each block, so two sets of tubes can be held at two different temperatures on one instrument.

Two Blocks, Two Set Points

The photo shows a blue housing with two recessed block positions, one carrying screw-capped vials and the other smaller coloured tubes, and two red displays showing different values with a row of buttons beneath each. That layout is what distinguishes a dual block unit: each block is controlled on its own, so one side can sit at 37 °C while the other runs hotter.

Many protocols move samples between two temperatures, for example an incubation followed by enzyme inactivation, or an annealing step followed by a warm wash. With a dual block dry bath both temperatures are ready at once, and the tubes simply move from one side to the other. It also lets two groups share one instrument while running different methods.

The two sides are pictured with different blocks, vials in one and tubes in the other, which is how such units are usually set up. The Digital double dry bath is the sibling to compare: it is pictured with a single display, which points to both block positions sharing one temperature. Block formats and the range of each side should be confirmed for the supplied model.

Two-Temperature Workflows

• Enzyme digest on one side and heat inactivation on the other
• Annealing or hybridisation at one temperature with washes at another
• Two student groups running different practicals on one instrument
• Warming vials of reagent on one side while tubes incubate on the other

Specifications

Care & Handling

• Note which block holds which set point, so tubes are not moved to the wrong side.
• Check each block separately with a thermometer in a water-filled tube or vial.
• Lift hot blocks only with the proper tool and let them cool on a heat-resistant surface.
• Wipe the wells and housing when cool, keeping liquids away from the controls.

Why Choose LabEquip

Molecular biology and biochemistry labs that routinely move samples between two temperatures choose a dual block unit to avoid resetting a single heater mid-protocol. Interchangeable formats such as the Block for Tubes or Microplates are listed in General Lab Products.

Frequently Asked Questions

Can the two blocks run at different temperatures?

The photo shows a separate display and set of buttons for each block, reading different values, which is how dual block units provide two set points. Confirm this for the model supplied if your protocol depends on it.

What is the difference between dual block and double dry baths?

In this range the dual block model is pictured with independent controls for each block, while the double model is pictured with one display. Independent control gives two temperatures; a single controller gives more capacity at one temperature.

Can different blocks be used on each side?

The photo shows vials in one block and tubes in the other, so mixed formats are the usual arrangement. Match each replacement block to the size of the block position.

Does heating one side affect the other?

The blocks sit close together, so a very hot block can warm its neighbour slightly. Check the cooler side with a thermometer when the two set points are far apart.

How should tubes be moved safely between blocks?

Use a tube rack or forceps for hot tubes, and move them promptly so they do not cool on the way. Keep caps closed or locked to prevent splashing.

How is the unit cleaned?

Switch off and let the blocks cool, lift them out if they are removable, and wipe the wells and housing with a damp cloth. Dry everything before switching on again.
