Muffle Furnace With Communication Port 7.5L Overview
The Muffle Furnace With Communication Port 7.5L (model FO301CR) from Yamato Scientific is a high-temperature laboratory furnace with a 7.5 L heating chamber, supplied through LabSupplies.com as an authorized dealer. Labs use it for ashing, ignition, heat treatment, and sample preparation that demand a clean, enclosed thermal environment.
An integrated communication port distinguishes this unit, letting technicians connect the furnace to external monitoring and data-acquisition systems. Digital connectivity supports documented temperature records, which matters for regulated workflows and method validation. Chamber dimensions and refractory construction details are available on request.
Two voltage configurations cover most facility power standards: FO301CR runs on 115V, while FO311CR runs on 220V. Both share the same 7.5 L capacity and communication functionality. Weight, footprint, country of origin, and certification documentation can be confirmed before purchase. Units ship from USA inventory.
