Frequently Asked Questions

1. What is the main advantage of the KISS 112A's 12-liter bath?
The larger 12-liter capacity and wide 130 x 310 mm opening allow for the immersion of larger laboratory vessels or multiple samples simultaneously while maintaining visibility through the transparent polycarbonate.

2. Can I use this circulator for external systems?
Yes, the KISS 112A includes a pump adapter and M16x1 connections at the rear, making it suitable for temperature control of external, closed laboratory applications.

3. How does the KISS controller simplify laboratory work?
The KISS controller is designed for ease of use, featuring a bright OLED display that can be read from a distance and a simple 3-button interface for quick temperature adjustments.

4. Is it possible to cool the bath to temperatures below 25°C?
While the standard heating range starts at 25°C, an optional cooling coil can be connected to tap water to reach temperatures as low as 20°C.

5. Is this model safe to use with flammable bath liquids?
Yes, the KISS 112A is rated Safety Class III (FL) according to DIN 12876, meaning it includes adjustable overtemperature protection and a low-level sensor specifically for use with flammable fluids.
