Factory Direct Sale Soap Gel Strength Testing Machine

Gel strength can be defined as a measure of the ability of a colloidal dispersion to develop and retain a gel form based on its resistance to shear.


Gels are widely used in the food industry, but are also involved in the biomedical and cosmetic fields. Gel strength is an important physical property of gels and is one of the indicators that determine the commercial value of gels.


In the gelatin industry, the measure of gel strength is commonly known as bloom. It is the amount of force×distance, measured in gcm, required to indent the surface of a gelatin gel by 4mm using a standard 5 mm cylinder probe. Therefore, the higher the value, the greater the firmness of the gel.

Sample preparation

The gel was made by pouring 6.67% gelatin solution into a gel cup and cooling it in a thermostat bath at 10°C for 17 hours.

Test Process

In the test, a punch probe of a specific diameter and length is used to compress the surface of a gel specimen at a constant deformation rate, until puncture occurs. Normally the speed used is 60mm/min, probe φ5mm and penetration distance of 4mm.

Technical Features

It’s a PLC controlled unit (industrial level stable) and HMI touch screen operated. Precision ball lead screw mechanism ensures good and steady speed and displacement control. Its specially designed program can be used for different parameters concerning gel strength test.
