1L 2L 3L 5L Hand Operated Laboratory Vacuum Mixer

Product Overview

This hand-operated laboratory vacuum mixer combines vacuum mixing and high-efficiency dispersion in one compact research unit. It is designed for controlled preparation of small batches where uniformity, air removal, and repeatable processing are important. A soft-sealing structure maintains a vacuum state of -0.098 MPa for more than 24 hours, helping protect process consistency during extended laboratory work.

The equipment is suitable for positive and negative electrode slurry preparation in lithium battery research, as well as glue, chemical, and other laboratory mixing processes. Available reference configurations provide 1 L and 2 L effective capacities, making the system practical for formulation screening, process development, and sample-scale production.

A precision-finished 304 stainless steel vessel, dual precision guide columns, handwheel-operated cover movement, and variable-speed drive provide a dependable foundation for demanding research environments. The unit also supports heating from 0 to 80°C and programmable operation from 0 to 99 hours, giving users greater control over time-sensitive mixing procedures.

Key Features

• Integrated Vacuum Mixing and Dispersion: The system combines vacuum processing with high-efficiency dispersion, supporting slurry preparation and other formulations that require thorough blending and reduced air inclusion.

• Extended Vacuum Retention: A soft-sealing design can maintain a -0.098 MPa vacuum state for more than 24 hours. This supports longer process cycles and helps maintain stable conditions between mixing stages.

• Dual Precision Guide Support: Two precision guide columns stabilize cover movement and improve alignment during opening and closing. The handwheel-operated lifting mechanism offers direct, controlled handling for laboratory operators.

• High-Quality 304 Stainless Steel Vessel: The mixing vessel is manufactured from 304 stainless steel for a robust, cleanable, and laboratory-suitable process surface. The vessel is precision-machined on a large horizontal lathe and polished with an automatic precision polishing machine.

• Dual Dispersion Impellers: The dual dispersion blade arrangement drives material upward, downward, and around the vessel. This three-dimensional circulation promotes rapid and uniform slurry mixing throughout the batch.

• Variable-Speed and Torque Adjustment: A geared mixing motor with frequency-converter adjustment allows operators to select different speeds and torque conditions according to formulation requirements, viscosity, and process stage.

• Broad Speed Range: Mixing speed can be adjusted from 0 to 1400 revolutions per minute through the frequency converter. This range supports gradual wetting, controlled dispersion, and higher-speed homogenization within one process platform.

• Optional Heating Capability: The heating function provides a temperature range of 0 to 80°C. Controlled heating can assist formulations and process studies that require temperature adjustment during mixing.

• Programmable Timing: A timer can be set from 0 to 99 hours. When the set time is reached, the unit automatically stops while maintaining the vacuum state, helping improve process repeatability and operator convenience.

Applications

Technical Specifications

The following specifications apply to the referenced configurations and functions. The source material provides 1 L and 2 L variants; 3 L and 5 L search terms should be confirmed with the supplier before ordering.

The 1 L configuration uses a 0.55 kW, 220 V drive and a vessel with a Φ102 mm internal wall diameter and 185 mm height. The 2 L configuration uses a 0.75 kW, 220 V drive and a larger vessel with a Φ125 mm internal wall diameter and 200 mm height. Both configurations share the same 0–1400 r/min variable-speed range, vacuum-retention capability, dual dispersion blade design, 304 stainless steel vessel construction, heating range, timer function, and handwheel-operated cover arrangement.

The vessel dimensions and effective volume should be reviewed together when selecting a configuration. Formulation viscosity, material loading behavior, required headspace, dispersion intensity, and desired batch size can all influence the most suitable setup. For procurement teams evaluating 3 L or 5 L capacity requirements, confirmation of the available configuration and corresponding technical data is recommended before purchase.

The timer function allows a process duration between 0 and 99 hours. At the end of the programmed cycle, the equipment automatically stops and maintains the vacuum state. This arrangement is useful for experiments that require a defined mixing duration, unattended cycle completion, or consistent comparison between formulations.
