Product — CELLERAX LS-2X7

Overview

Precision Bioprocessing, Redefined

Designed for research laboratories and pilot-scale production facilities, the CELLERAX LS-2X7 delivers exceptional control over every critical fermentation parameter. Its dual 10-liter borosilicate glass vessels with a height-to-diameter ratio of 3:1 are purpose-built for microbial culture applications, ensuring optimal oxygen transfer and mixing efficiency.

Each vessel is double-jacketed and fully autoclavable, constructed with all wetted parts in 316L stainless steel to guarantee chemical resistance and product integrity. The Rushton impeller system, driven by a 400W servo motor through a single mechanical seal, provides reliable agitation from 1 to 2,000 RPM.

Capabilities & Advantages

Built for Modern Bioprocessing

From recipe-driven automation to robust process safeguards, the CELLERAX LS-2X7 is engineered to deliver reliable, repeatable results.

Automatic Mode Control

Program automatic adjustments of feed rate, air and oxygen flow rates, pH, and agitator motor speed. Transitions seamlessly between process phases based on user-defined trigger conditions.

Recipe Management

Create and execute multi-step recipes with fully automatic transitions. Define custom trigger conditions for each phase shift, enabling complex cultivation protocols without manual intervention.

Process Safeguards & Alarms

Comprehensive performance monitoring and alarm system continuously tracks all critical parameters with instant alerts for deviations in temperature, pH, DO, foam level, and agitation.

Data Logging & Connectivity

LAN, VPN, and USB ports enable real-time remote monitoring, data download, and integration with laboratory information management systems. All process data is logged continuously.

Autoclavable Vessel Design

Double-jacketed borosilicate glass vessels are fully autoclavable, ensuring complete sterilization between runs. 316L SS wetted parts withstand repeated autoclave cycles without degradation.

Local Support & Fast Delivery

As a domestic manufacturer, CELLERAX offers stable and reliable technical services with significantly shorter delivery lead times compared to imported alternatives.
