ODRA2 Thermostatic Water Bath · 2 holes · RT+5 to 100 °C · 6.1 L
The thermostatic water bath ODRA2 is a compact bath with two holes in one row and a 6.1 L stainless steel tank, for two beakers or flasks side by side. A U-shaped heater sits directly in the water, and the PID controller keeps the temperature from RT+5 °C to 100 °C with 0.1 °C resolution. Concentric rings in each hole close the opening around vessels of different sizes.

A small water bath for two vessels
Many routine steps need two containers at the same temperature — a sample and a control, or two reagents used together. ODRA2 holds them side by side on a small bench footprint and heats only 6.1 L of water. The deep-drawn tank has rounded corners and is easy to clean, the ring lid reduces evaporation and heat loss, and the perforated tray keeps vessels off the heater.
Key features
- Temperature RT+5 °C to 100 °C, resolution 0.1 °C
- Two holes in one row, 6.1 L deep-drawn stainless steel tank, 300 × 135 × 150 mm
- U-shaped stainless steel heater directly in the water, 500 W
- PID controller with actual (PV) and set (SV) value display, auto-tuning and alarm
- Stainless steel lid with two holes and concentric rings, perforated tray included
- Compact powder-coated steel housing
Suitable for
- Two beakers, flasks or bottles at the same temperature
- A sample and a control side by side
- Warming reagents and media, thawing samples
- Teaching labs and simple QC steps up to 100 °C
When to choose a two-hole water bath
Choose ODRA2 when you heat two vessels at a time and want a small bath that is quickly filled and emptied. For many containers or large racks see the PURUS62 large 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, dry bench next to an earthed 220 V socket. Fill the tank with distilled or deionised water above the heater before switching on the heating, keep the lid on to reduce evaporation, and change the water regularly to keep the stainless steel tank clean.
