Expert Advice

Does the K-350 have a cooling water control valve?

Yes, this valve opens only during the distillation process and therefore helps saving water.

What is the distillation rate of the K-350 and K-355?

At 100 % steam power, the amount of distillate obtained is >30 mL per minute.

Why is the K-355 suitable for non-Kjeldahl applications (direct distillations) e.g. formaldehyde, SO2, phenols, cyanide?

The K-355 has a special acid resistant pump that allows automated dosing of acids which is required for many direct distillation applications.
