AID bacSpot Robot Systems

Efficiency and Constant Measurements

The AID bacSpot Robot is your automated Colony Counter for every application. The automation of colony counting on agar plates will become increasingly important in the future, not only to relieve employees of the demanding visual counting work and to free up capacities for more meaningful occupation. But even to guarantee and ensure constant results and carefree automatic documentation from a regulatory perspective.

Two Different Models – One Principle

60mm and 90mm Plates

With the bacSpot Robot systems we present two models, one for 90mm plates and one for 60mm plates, which have been developed for automatic counting of colony forming bacteria, yeasts and moulds on different types of agar. Both models have the ability to sort plates into colony positives or negatives according to freely selectable threshold values. The plates are processed in high-throughput mode.
The AID bacSpot Robot is the automated colony counter for hightrouhput of 90mm and 60mm agar plates

Tailor-Made Algorithms

Individual Industry and Application Solutions

Based on an enormous set of adjustable measurement parameters, sophisticated illumination methods and the modular algorithm structure, the bacSpot systems can be individually adapted to customer-specific requirements. This approach thus enables solutions for a wide range of applications and resorts in pharmaceutical industry, food and drinking water control, environmental investigations and more.

Preset bacSpot Systems

Easy Operation and Handling

The philosophy behind the bacSpot systems is to provide customers with a device that has been perfectly prepared at AID for their stereotypically recurring tasks. The simple batch loading as well as a quick start for operating the system with just a few mouse clicks makes working with the device intuitive and convenient. The results can be automatically exported to LIMS, Excel etc. and also merged with other data.

The AID bacSpot ML colony counter is suitable for various plate formats and low troughput

AID bacSpot ML

The Automatic Colony Counter Solution for Smaller Amounts of Plates

With its sophisticated illumination construction and software the AID bacSpot ML ensures comfortable counting and proper documentation of results. Due to the versatile software capabilities this smaller device does not stand behind the robotic system in terms of analysis or data integration. The AID bacSpot ML is suitable for various plate formats and low plate throughput. The AID bacSpot ML is not an off-the-shelf solution but rather a development platform for the robot system.
