PURUS11 — Thermostatic Water Bath 11 L
OVERVIEW
PURUS11 is a compact high-capacity thermostatic water bath with 11 L volume, designed for routine laboratory heating tasks where stable temperature control is required. It supports a working temperature range of RT+5°C to 100°C (with boiling function) and features an intelligent microprocessor PID temperature controller with auto-diagnostic and error indication.
The bath is built around a stainless-steel chamber with surface electrolysis treatment and rounded corners for easier maintenance. The interface shows set temperature, actual temperature and remaining time, while the timer (0–9999 min) supports programmed heating time and delayed start (timer starts when set temperature is reached).
Designed for day-to-day usability and safety, PURUS11 includes water discharging (drainage), double over-heating protection, a code lock for parameter settings, and optional smart features such as Wi-Fi control by smartphone (depending on configuration).
COLO.SCIENCE KNOWLEDGE
How to choose a thermostatic water bath (volume, temperature range, control)
On COLO.Science you will find practical guidance for selecting water bath capacity (L), temperature range (RT+5 to 100°C), stability, safety features and accessories (lids, racks, interfaces) for routine lab workflows.
TYPICAL APPLICATIONS
