4-Channel Smart Evaporator for Fast, Bump-Free Sample Concentration

The BioChromato K4 Smart Evaporator is an advanced bump-free solvent evaporation system designed to concentrate samples quickly and safely directly inside laboratory vials. Featuring vacuum-assisted vortex evaporation technology and spiral plug design, the K4 allows solvents to evaporate smoothly without bumping or sample loss.

Unlike traditional evaporation methods, the Smart Evaporator generates a controlled vortex inside the vial, allowing solvents to evaporate evenly while maintaining sample integrity. The K4 model supports up to four samples simultaneously, making it ideal for laboratories processing multiple samples in parallel.

The system uses aluminum bead heating media capable of reaching 100 °C, providing uniform heat transfer and compatibility with vials of various bottom shapes.

Manufactured in Japan by BioChromato, the K4 Smart Evaporator is widely used in organic chemistry, pharmaceutical research, environmental testing, material science, and biochemistry laboratories.

Key Features of the BioChromato K4 Smart Evaporator

Bump-Free Evaporation Technology

Patented spiral plug and vortex evaporation system prevents solvent bumping while ensuring consistent evaporation.

Evaporate High-Boiling Solvents

Capable of safely evaporating difficult solvents such as:

• DMSO

• DMF

• Water

4-Channel Evaporation

Process up to four samples simultaneously, improving laboratory productivity.

Direct Evaporation from Analytical Vials

Solvents can be removed directly from:

• HPLC vials

• LC/MS vials

• GC vials

This eliminates sample transfer and reduces contamination risk.

In-Vial Sample Concentration

Allows concentration directly inside the vial without transferring samples between containers.

Aluminum Bead Heating System

Uses aluminum beads as heat media, allowing uniform heating and compatibility with vials of various shapes.

Minimizes Sample Loss

Direct in-vial evaporation significantly reduces sample loss caused by transfer steps.

Made in Japan

High-quality engineering and manufacturing from BioChromato Japan ensures reliable laboratory performance.
