Manual Tablet Press with Dual Scale Pressure Gauge for Pharmaceutical Food Chemical Laboratory Sample Preparation

Product Overview

This manual tablet press is a precision-engineered, hand-operated hydraulic machine designed to convert powdered materials into solid, uniform tablets with exact dimensions and density. Built around a robust monolithic frame that integrates oil reservoir, main plate, and hydraulic cylinder, the press eliminates the need for multiple seals and connections that are common failure points in conventional designs. Its compact 260×175×395 mm footprint and 42 kg weight make it easy to integrate into any laboratory layout, including glovebox enclosures for controlled atmosphere processing.

Primarily deployed in pharmaceutical laboratories for formulation development and small-scale clinical trial production, this system also serves the food, chemical, and advanced materials industries where consistent tablet properties are critical for quality control or subsequent processing. Whether you are pressing active pharmaceutical ingredients, food-grade flavor tablets, catalysts, or ceramic powders, the manual press delivers repeatable results with minimal setup time.

Engineered for durability and operator safety, the press features a hard-chrome-plated piston that resists corrosion and ensures smooth, leak-free operation even after thousands of cycles. A transparent protective shield surrounds the pressing area while maintaining full visibility of the process. The intelligent design of the pressurization lever and extended tension spring allows effortless manual force generation up to 24 tons, and the dual-scale pressure gauge eliminates mental conversion errors, protecting both the tooling and the product. With its straightforward maintenance routine and long-life components, this manual tablet press is a reliable workhorse for any sample preparation workflow.

Key Features

• Compact and Portable Construction: With a lightweight design and small footprint (260×175×395 mm), this press easily fits inside glove boxes and can be relocated without effort, facilitating multi-station laboratory work. Its low-profile build also ensures stability during operation, even under maximum load, while the four sturdy columns provide a rigid pressing axis.
• Integrated Monolithic Structure: The oil reservoir, main plate, and cylinder are machined from a single block, eliminating joint seals and drastically reducing the risk of hydraulic oil leaks. This design not only enhances long-term cleanliness but also improves pressure stability, as there are fewer interfaces where compliance could introduce variability.
• Dual-Scale Pressure Gauge: The pointer-type gauge simultaneously displays applied force in tons and hydraulic pressure in MPa, allowing operators to set the required pressing force without conversion and protecting molds from accidental overpressure. An optional digital gauge with 0.01 MPa resolution is available for users who require finer monitoring and data logging capabilities.
• Corrosion-Resistant Chrome-Plated Cylinder: The Φ95 mm piston rod is hard chrome plated, providing a smooth, rust-free surface that maintains excellent sealing performance and consistent stroke repeatability after thousands of cycles. The high-quality rubber seals further ensure that even under extended dwell times, the cylinder holds pressure without creep.
• Ergonomic Manual Operation: The pressurization lever is strategically positioned at a low angle to deliver maximum mechanical advantage with minimal operator effort, preventing machine tipping during pressing and reducing fatigue during repeated use. This thoughtful placement also makes it easier to apply force incrementally, crucial for sensitive powder formulations.
• Quick-Change Oil System: The oil pool is located on the top surface for convenient access, allowing rapid oil changes without disassembly. An integrated filtration device captures contaminants before they reach the cylinder, prolonging component life. The extended tension spring guarantees a smooth and complete 30 mm piston return, maintaining proper alignment over the machine's lifetime.
• Safety and Durability Features: A transparent organic glass shield protects the user from flying debris while maintaining full visibility of the pressing zone. Electroplated countersunk screws on the top plate eliminate sharp edges, and the all-aluminum handwheel combines lightweight durability with a professional finish, ensuring reliable day-to-day usage.
• Precision Mold Compatibility: The standard Φ105 mm worktable accommodates a wide variety of die sets, and the four-column frame provides even pressure distribution, enabling the press to produce tablets with consistent thickness and density. The 80×130 mm working space offers sufficient clearance for loading and ejection, accommodating most standard lab tooling.
