Description

Tablet press is used in laboratory

Technical Field

The utility model belongs to the technical field of the tablet is suppressed, specifically speaking relates to a tablet press is used in laboratory.

Background

The tablet is a flaky or specially-shaped flaky solid preparation which is prepared by uniformly mixing the medicament and auxiliary materials and then pressing. Tablets are generally made from the raw materials, fillers, adsorbents, binders, lubricants, dispersants, wetting agents, disintegrants, flavors, colorants, and the like. The general process of tablet preparation is to crush, granulate and dry the materials, then to make them into tablets with a tablet machine, or to directly press them into tablets without granulating and drying.

A tablet press is a machine that presses dry granular or powdery materials into tablets through a die. During the development of tablet drugs, drug particles of different formulations are compressed into tablets during the pilot and pilot test trials, usually using a laboratory tablet press. Such small laboratory tablet presses are typically single punch presses that can only compress one tablet at a time, requiring manual feeding by a worker and removal of the compressed tablet. In the prescription exploration stage of the tablet, different formulas are required to be tested, and dozens of tablets or dozens of tablets are pressed at one time to test the prescription condition, so that the single-punch tablet machine can meet the working requirements. However, in the pilot-scale test stage, hundreds or even thousands of tablets are generally needed, and manual tabletting is performed by using the tablet press, so that the time and the labor are consumed, and the working efficiency is low.
