Per4mance Stainless Steel Water Bath
2 Liter
Touch Glass Panel · 3 Programmable Setpoints · ±0.5°C Stability · Single-Piece Stainless Basin · Dual Voltage
The 2-liter Per4mance water bath is built for the bench where space is scarce and precision still matters — serology, small-volume reagent warming, enzyme reactions in tubes and microtubes. Three stored setpoints launch your most-used temperatures with one press, while independent over-temperature cutoff and dry-start detection protect samples and the basin when attention shifts elsewhere.
Why Single-Piece Stainless Matters
Small-capacity water baths are the most abused instruments in any lab — used a dozen times a day, rarely refilled with care, and expected to deliver reproducible temperatures for protocols that fail silently if the bath drifts by a degree. Cheap units cut corners on the controller and the basin, so drift compounds and welded seams corrode within a year.
The WBT200102 uses a continuous microprocessor-regulated heater in a single-piece drawn stainless chamber — no seams to corrode, no firmware shortcuts on temperature control. Stability holds at ±0.5°C across the full RT+5°C to 99.9°C range, day after day, with no recalibration drift.
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.
