Problems: In systems that perform batch control of sample racks and trays with bar codes, the inspection instructions and sorting information are handled at the host system. This gives rise to complicated programs and configurations, making it difficult to change the system when required. A new bar code label must be attached each time the sample racks and trays are cleaned. The labels have to be attached carefully without being creased.
Read information from the bar codes on the test tubes with a bar code reader, and store that information along with inspection instructions and sorting information in the ID Tags embedded in the sample racks and trays. Write inspection history information and inspection results to the ID Tags and, in the final process, upload the information to the host system.
Know-How
The compact ID Tags can be embedded in the sample racks and trays. High resistance to the environment - resistant to chemicals and temperatures of up to 110°C (230°F) and capable of withstanding IPA cleaning and ultrasonic cleaning. Communications are possible even when embedded in metal and so the ID Tags can be used with metal racks. The ID Tags have an information capacity of 240 bytes min., much larger than that of bar codes.
Benefits
Even though the inspection items vary with the sample, inspections and sorting based on the inspection instructions stored in the ID Tags can be performed automatically, efficiently, and reliably. The bar code labels do not require reattachment, reducing labor requirements and consequently labor costs. Interruption processing, such as for urgent inspection samples, can be handled smoothly and accurately.
