PURUS62 Large Thermostatic Water Bath · RT+5 to 100 °C · 62 L
The large water bath PURUS62 holds 62 L of water in a 620 × 500 × 200 mm stainless steel tank — room for big tube racks, bottles, flasks and bags at one temperature. A U-shaped heater sits directly in the water, so the bath heats up quickly with little heat loss, and the PID controller keeps the temperature from RT+5 °C to 100 °C with ±0.5 °C stability.
Model and order code
| Model | Order code | Temperature | Stability | Tank | Exterior W × D × H |
|---|---|---|---|---|---|
| PURUS62 | PRO8256 | RT+5 to 100 °C | ±0.5 °C | 62 L · 620 × 500 × 200 mm | 681 × 560 × 301 mm |
Stainless steel lid and perforated tray included. Supply 220 V, 50 Hz, 2.85 kW.
A water bath for large loads
Most laboratory water baths hold 10–30 L. When the samples do not fit — tall racks, many bottles of media, blood bags or large flasks — PURUS62 gives a 62 L tank with a flat perforated tray over the heater. The deep-drawn tank has rounded corners and is easy to clean, the stainless steel lid reduces evaporation, and the water can be let out through the side drain.
Key features
- Temperature RT+5 °C to 100 °C, stability ±0.5 °C, control accuracy ≤ ±1 °C
- 62 L deep-drawn stainless steel tank, 620 × 500 × 200 mm
- U-shaped stainless steel heater directly in the water, 2.85 kW
- PID controller with actual (PV) and set (SV) value display, auto-tuning and alarm
- Perforated stainless steel tray and stainless steel lid included
- Powder-coated steel housing, side drain outlet
Suitable for
- Large tube racks and many samples at one temperature
- Warming bottles of culture media, reagents and buffers
- Thawing plasma and frozen samples, melting agar
- General constant-temperature incubation and heating up to 100 °C
When to choose a large water bath
Choose PURUS62 when the load does not fit a standard bath or when you warm many containers at once. For smaller volumes see the PURUS thermostatic water bath; when the samples must also be shaken in the water see the ORSHAWB shaking water bath.

Installation and care
Place the bath on a level, stable bench — filled, it weighs about 80 kg. Use a separate earthed 220 V socket rated for 2.85 kW and keep a drain within reach of the side outlet. Fill the tank with distilled or deionised water above the heater and tray before switching on the heating, and change the water regularly to keep the stainless steel tank clean.
