Per4mance Stainless Steel Water Bath
5 Liter
Touch Glass Panel · 3 Programmable Setpoints · ±0.5°C Stability · Single-Piece Stainless Basin · Dual Voltage
The 5-liter Per4mance water bath is the general-purpose lab workhorse — roomy enough for flasks, tube racks, and multiple reagent bottles, compact enough to live on a shared bench. Three stored setpoints, a sealed glass touch panel, and dual-layer safety make it the default choice for microbiology, molecular biology, and routine clinical workflows.
Why Single-Piece Stainless Matters
Mid-size water baths are where most labs compromise — they buy the cheap option assuming it's a commodity, then spend the next five years wrestling with drift, membrane keypads that crack under ethanol, and welded basins that corrode through right above the heating element.
The WBT200205 solves all three at once: a single-piece drawn stainless basin with nothing to corrode, a sealed glass touch panel that wipes clean with any lab disinfectant, and ±0.5°C stability held by a continuous microprocessor controller — not a setpoint-and-hope thermostat.
Lab-Grade Stability
Holds ±0.5°C across the full RT+5°C to 99.9°C range — tight enough for enzyme kinetics, PCR reagent prep, and serology protocols that drift when the bath drifts.
3 Stored Setpoints
Three configurable program buttons launch your most-used temperatures with a single press. No more dialing in 37°C, 56°C, and 95°C by hand every morning.
Dual-Layer Safety
Independent over-temperature cutoff plus dry-start protection means a forgotten fill or a runaway setpoint shuts the heater down before samples — or the basin — take damage.
Glass Touch Control
Sealed glass panel wipes clean with any lab disinfectant. No buttons to trap protein spills, no membrane to crack under ethanol, no crevices to grow biofilm.
"Heats to 99.9°C. Stops at 100.1°C." — The over-temperature cutoff is a physically independent circuit, not a firmware check. If the primary controller fails, the secondary kills power before water boils dry.

Ideal Applications
Microbiology
Serology at 56°C, media tempering at 50°C, agar holding at 47°C — all three stored as one-touch presets.
Molecular Biology
Heat-shock transformations, enzyme inactivation at 65°C/80°C/95°C, and reagent thawing with reproducible stability.
Cell Culture
Media and reagent warming at 37°C with tight stability — critical when thawed proteins meet sensitive cell lines.
