LW Scientific Dry Bath Replacement Heat Block - DBP Series | Anodized Aluminum - Made in USA

Running out of the right heat block in the middle of a protocol means stopping everything — swapping blocks, re-equilibrating, and losing precious incubation time. LW Scientific Dry Bath Heat Blocks let you keep dedicated blocks for every tube size your lab uses, so you never have to interrupt a run. These anodized aluminum blocks drop into any LW Scientific dry bath incubator base unit and reach thermal equilibrium quickly thanks to high-conductivity aluminum construction.

Available in three configurations — 20-place for 1–2 mL microcentrifuge tubes, 12-place for 6–15 mL conical tubes, and 4-place for 50 mL conical tubes — each block is precision-machined to hold tubes upright and secure with full-wall contact for uniform heat transfer. Keep a spare set on hand or expand your dry bath's versatility by stocking all three sizes.

Features and Benefits

• Anodized Aluminum Construction: High thermal conductivity ensures rapid, uniform heat transfer from the dry bath base to every tube position. Anodized surface resists corrosion and chemical exposure.

• Drop-In Compatibility: Designed exclusively for LW Scientific dry bath incubators (DBL series). Blocks lift out and install in seconds without tools or adapters.

• Three Tube Size Options: Choose 20-place for 1–2 mL microcentrifuge tubes, 12-place for 6–15 mL conicals (OD 17 mm), or 4-place for 50 mL conicals (OD 28.5 mm).

• Precision-Machined Wells: Each well is bored to exact tube diameters for snug, upright fit — maximizing surface contact area and eliminating tube wobble during incubation.

• Expand or Replace: Purchase additional blocks to run dedicated configurations for different protocols, or replace worn blocks to maintain optimal thermal performance.

Laboratory Applications

• Dedicating separate blocks to different protocols — keep a 2 mL block permanently set up for PCR prep and a 15 mL block for enzyme digestions without constant swapping

• Expanding dry bath versatility by adding tube sizes not included with your original incubator purchase

• Replacing worn or damaged blocks to maintain optimal thermal contact and temperature uniformity across all well positions

• Equipping teaching laboratories with multiple block sets so student groups can run different tube-size experiments on the same dry bath units

Frequently Asked Questions

Which LW Scientific dry baths are these blocks compatible with?
These blocks fit all LW Scientific DBL-series digital dry bath incubators, including the DBL-40PL-02DP, DBL-24PL-15DP, DBL-08PL-50DP, and DBL-16PL-11DP. They are not compatible with dry baths from other manufacturers.

Do I need tools to swap heat blocks?
No. Each block has a lifting handle and drops directly into the dry bath well cavity. Swap time is under 10 seconds. Allow the new block to reach thermal equilibrium before loading samples.

Can I use two different block sizes in the same dry bath at once?
Yes. LW Scientific dry baths accept two blocks side by side. You can install any combination — for example, one 2 mL block and one 50 mL block — and both will heat to the same controller setpoint.

Are replacement blocks sold individually?
Yes. Each block is sold as a single unit. Since LW Scientific dry baths hold two blocks, order two if you want a matched pair of the same size.

Quality Assurance

LW Scientific heat blocks are precision-machined from anodized aluminum and manufactured in the USA. Each block is inspected for dimensional accuracy to ensure proper fit and thermal contact with the dry bath base unit.
