LW Scientific Digital Dry Bath Incubator - DBL-40PL-02DP | 40-Place 2mL PID Control

Waiting for a water bath to heat up — then worrying about contamination, evaporation, and weekly cleaning — wastes time that belongs at the bench. The LW Scientific DBL-40PL-02DP Digital Dry Bath Incubator eliminates every one of those problems. This USA-made benchtop heater delivers precise, stable temperatures from ambient +5°C to 150°C using PID microprocessor control, so your enzyme digestions, PCR prep, and cell lysis reactions hit the exact temperature they need — and stay there.

Two interchangeable 20-place anodized aluminum blocks hold a total of 40 microcentrifuge tubes (1–2 mL) simultaneously. The bright LED display shows both setpoint and real-time temperature at a glance. Durable metal construction, suction-cup feet for bench stability, and a universal 90–240 VAC power adapter mean this incubator is ready to work in any laboratory in the world — straight out of the box.

Features and Benefits

• 40-Tube Capacity: Two 20-place anodized aluminum heat blocks accommodate 40 microcentrifuge tubes (1–2 mL) at once, letting you run full-plate PCR prep or batch enzyme reactions without waiting for a second cycle.

• PID Microprocessor Control: Digital PID regulation maintains setpoint accuracy within ±0.5°C, eliminating the temperature overshoot and drift common in analog dry baths.

• Wide Temperature Range: Heats from ambient +5°C to 150°C, covering every common incubation protocol from gentle enzyme reactions at 37°C to sample denaturation at 95°C and beyond.

• Dual LED Display: Simultaneously shows setpoint and actual temperature so you can confirm thermal equilibrium before loading samples — no guesswork, no separate thermometer needed.

• Interchangeable Block System: Blocks lift out and swap in seconds. Purchase additional blocks for 50 mL tubes, 6–15 mL tubes, or mixed configurations to adapt this one unit to every tube size in your lab.

• Universal Power Supply: Ships with a 90–240 VAC adapter, making the unit operational on any mains voltage worldwide without an external transformer.

• USA Designed and Assembled: Engineered and built in Atlanta, Georgia. Solid metal housing with insulated body and block-lifting handle ensures years of daily use in demanding lab environments.

Specifications

Laboratory Applications

• PCR preparation — pre-heating microcentrifuge tubes of master mix and template DNA to 95°C denaturation temperature before loading into the thermal cycler

• Restriction enzyme digestion — maintaining 37°C incubation for genomic or plasmid DNA restriction reactions in 1.5 mL tubes

• Cell lysis and protein denaturation — heating samples to 70–100°C for SDS-PAGE sample preparation or bacterial cell lysis

• Serum and reagent thawing — gentle warming of frozen aliquots at 37°C without the contamination risk of a water bath

• ELISA and immunoassay incubation — holding microtubes at a stable 37°C for antibody-antigen binding reactions requiring extended incubation times

Frequently Asked Questions

What tube sizes fit the DBL-40PL-02DP dry bath incubator?
This unit ships with two 20-place heat blocks designed for standard 1–2 mL microcentrifuge tubes. You can purchase separate interchangeable blocks to accommodate 6–15 mL tubes (SKU: DBP-12PL-1577), 50 mL tubes (SKU: DBP-04PL-5077), or 0.5–2 mL tubes in a 20-place configuration (SKU: DBP-20PL-0277).

How accurate is the temperature control on this dry bath?
The digital PID microprocessor provides precise temperature regulation with minimal overshoot. The LED display shows both the setpoint and actual real-time temperature, allowing you to verify that the unit has reached thermal equilibrium before loading your samples.

Can I use this dry bath incubator with international power outlets?
Yes. The included power adapter operates on 90–240 VAC, making it compatible with mains voltage in North America, Europe, Asia, and other regions without an external step-down or step-up transformer.

Is this dry bath manufactured in the USA?
Yes. LW Scientific designs, engineers, and assembles this unit in Atlanta, Georgia, USA. The company provides direct technical support from their US-based team.

How does a dry bath differ from a water bath for tube incubation?
A dry bath uses solid aluminum blocks instead of heated water, eliminating the risk of water contamination reaching tube caps, removing the need for weekly water changes and biocide treatment, and providing faster temperature recovery when cold samples are loaded. Dry baths also have a smaller benchtop footprint than most water baths.
