MRVS-1003 High-Vacuum Rotary Sealing – Quartz Tube Sealing System — 1

Overview

The MatMeas MRVS-1003 Rotary Vacuum Tube Sealer is engineered for high-temperature vacuum solid-state synthesis and airtight sample encapsulation under anhydrous and oxygen-free environments.

Compared with conventional vacuum tube furnace sealing, the system integrates dynamic vacuum sealing technology, enabling simultaneous rotary evacuation and high-temperature HHO flame fusion sealing. This significantly reduces raw material loss, prevents secondary contamination, and ensures ultra-high vacuum integrity for crystal growth and defect engineering.

With adjustable rotary motion, ultra-low leak rate, and high-temperature flame capability, the system provides a reliable solution for advanced material preparation workflows.

FAQ

  • How does the MRVS-1003 protect the vacuum pump when sealing ultra-fine powder samples?

    Vacuuming fine powders is challenging as they can easily compromise the vacuum level. The MRVS-1003 specifically resolves this by offering a dedicated powder anti-reflux kit (PAR16KIT). This critically prevents powder materials from being sucked into the high-vacuum pipeline, minimizing sample loss and significantly extending the lifespan of the molecular pump.

  • What is the maximum length and size of the quartz tubes that can be sealed?

    The system is highly versatile. By utilizing customized tube fittings, it seamlessly accommodates quartz tubes with varying outer diameters including Φ13mm, Φ15mm, Φ20mm, and Φ45mm. Furthermore, the machine body is designed to be flipped and tilted by 20 degrees, allowing researchers to effortlessly seal ultra-long quartz tubes exceeding 1 meter in length.

  • What vacuum pump configurations are available for different laboratory needs?

    The MRVS-1003 offers three flexible configurations to meet specific demands: a baseline version (S003) with a domestic 2L/s mechanical pump achieving 0.1 Pa; a high-vacuum version (S006) equipped with a German-imported molecular pump unit achieving an ultimate vacuum of 10⁻⁶ Pa; and a specialized powder-focused version (S008) combining both mechanical and molecular pumps for extreme experimental environments.
