Pupose of NXT_BCR

Liquid level detection without using expensive conductive disposable tips or image based liquid phase detection for centrifuged blood tubes including buffy coat detection are demands of applications in blood banks or medical reseach labs. The NXT_BCR is designed to store and present up to 96 samples in a temperature controlled environment down to 4°C to deck of liquid handler with Span-8 functionality. Furthermore image based detection of Barcode, tube type, liquid level and liquid phase can optionally be integrated, e.g. for centrifuged blood tubes.

The custom device was developed to allow handling on Biomek series NXp, FXp, i5 and i7 with Span-8 functionality. The device can be modified for other liquid handling robots on request.
