The spiral inoculation method has been widely used in the fields of food microbiology, medical bacteriology, food preservation and cosmetics since it was developed in 1973. It is a conventional method prescribed by AFNOR V08-100 and ISO 7218 standards.
Interscience has always been committed to the technical improvement and product development of spiral inoculation equipment. Finally, in 2012, the fourth-generation spiral inoculation instrument was launched, namely the world's first spiral inoculation instrument with gradient dilution easySpiral Dilute, which realized the automatic dilution and inoculation function. For customers with counting needs, both spiral counting method can be used to achieve rapid counting, and traditional gradient dilution method can be used for counting. The automated operation can greatly improve work efficiency.
This inoculation device can achieve 5 x 1 / 10th continuous gradient dilution and automatically spread the bacterial solution. The concentration range of the original bacterial solution that can be counted in one petri dish can reach 30 ~ 107 CFU / mL.

The original bacterial solution and the diluted bacterial solution can be selected in a uniform mode, simulating a manual gradient dilution inoculation method, or an exponential mode for decreasing concentration inoculation. After the inoculation, the petri dish is cultured. The picture is as shown in the picture above. You can choose manual counting or automatic colony counter to count.
The entire dilution and inoculation process is carried out automatically, eliminating errors caused by human operations, which can save up to 50% of manpower, material resources and time costs. The patented cleaning design ensures that no cross-contamination will occur. Ideal for laboratories.
