Surge Scientific · Model WB401
Digital Lab Water Bath
24 Liter
RT +5°C to 99.9°C · ±0.3°C Stability · Touch Glass Panel · 3 Programmable Setpoints · Stainless Steel Basin
When batch size grows — large-volume hybridizations, industrial-scale heat inactivation, or multi-rack simultaneous incubations — most water baths struggle to maintain uniformity across the full chamber. The WB401 24-Liter model delivers ±0.3°C stability at 1450W with the same programmable setpoints and dual-layer safety that define the WB Series, scaled to handle the highest-throughput lab workflows.
Why Temperature Stability Matters More Than You Think
Most bench-top water baths report a setpoint temperature and deliver something close to it — most of the time. The gap between "close" and "±0.5°C" matters enormously in enzyme kinetics, restriction digests, and serum heat-inactivation, where a 2°C drift doesn't just slow the reaction: it alters yield, reproducibility, and in clinical settings, can invalidate results entirely. Basic baths with analog controls or slow-cycling heaters create exactly this kind of drift during the quiet minutes when no one is watching.
The WB Series uses microprocessor-controlled regulation to maintain the setpoint continuously — not just on recovery from a cold load. The result is a bath you calibrate once, program once, and trust to deliver the same thermal environment across every run.
Precision You Can Count On
Microprocessor-controlled regulation holds temperature to within ±0.5°C (2L & 5L) or ±0.3°C (13L & 24L) with 0.1°C display resolution — maintaining the setpoint continuously, not just on recovery from a cold load.
Double-Layer Safety
Dry-start protection detects an insufficiently filled chamber and halts heating before damage occurs. An independent over-temperature cut-off and audible alarm engage if the bath exceeds the safe threshold — protecting your samples and the instrument even if the primary controller fails.
One-Touch Programmability
Three configurable program buttons store your most-used temperature and time setpoints. Launch your standard 37°C incubation, 56°C inactivation, or 99°C denaturation protocol with a single button press — no menus, no repeated manual entry.
Built to Last
The basin is formed from a single piece of durable stainless steel — no seams or weld joints that corrode or harbor contamination. Resists aggressive cleaning agents and years of thermal cycling without degradation.
Three programmable setpoints — one press to launch. Whether running restriction digests at 37°C, heat-inactivating serum at 56°C, or denaturing DNA at 99°C, your most critical temperatures are pre-stored and ready — eliminating manual entry errors that compromise time-sensitive protocols.

Ideal Applications
Molecular Biology
Restriction digests, ligation reactions, DNA denaturation, and enzyme incubations requiring precise, stable temperature maintenance throughout the reaction.
Microbiology
Bacterial culture growth at 37°C, serum heat-inactivation at 56°C, and media tempering for pour plates — consistent, reliable heating across the full protocol.
Cell Culture
Thawing cryopreserved cells, warming media, and maintaining reagent temperatures with the gentle, uniform heat transfer that only a water bath can provide.
