Rotary evaporator vacuum pump MV 10C EX VARIO +AK+EK

laboratorydiaphragmoil-free

Overview

• ATEX chemistry diaphragm pump unit with inlet separator (AK) and emission condenser (EK)
• VARIO®: hysteresis‑free vacuum control for shorter process times
• VARIO®: on‑demand speed control—reduced power use, extended maintenance intervals, low noise
• Optional VACUU·SELECT vacuum controller (with ATEX sensor) for precise, fully automatic processes
• Additional devices required for operation (e.g. ATEX vacuum sensor, Connection Box 100) — available from VACUUBRAND

Product description
The MV 10C EX VARIO is an oil‑free chemistry diaphragm pump unit designed for ATEX areas. Vacuum is regulated precisely by controlling motor speed via a 4–20 mA control loop. The VARIO® feature allows the pump to run only as fast as required for the process. The optional VACUU·SELECT vacuum controller, combined with an ATEX vacuum sensor and Connection Box 100, enables fully automatic evaporations: adaptive control detects boiling pressure and continuously adjusts the vacuum according to vapor pressure. VACUU·SELECT and the Connection Box 100 are installed in a non‑hazardous area.
