Designed for precision. Designed for economy. Designed for every lab.

 

No other qPCR set-up system can meet the precision found in Rob™. It has a large volume range of 0.5 – 200 µl with increments of 0.1 µl for maximal accuracy. Recently been CE IVD-registered, Rob™ was designed to keep production and run costs as low as possible. The software is designed to be very easy and straight forward to use. Everyone in your lab can make personal protocols after just 5 minutes of training.

 

 

 

 

Speed

Rob™ has two modes for doing qPCR set-up. Traditional mode uses one tip for every sample replicate and OneDip™ mode uses the same tip for all replicates doing serial dispensing. The example below is based on a qPCR set-up with three replicates and pre-made master mix.
 

One tip per replicate

96-plate: 27 minutes (18 µl mix + 2 µl sample)
384-plate: 95 minutes (5 µl mix + 2 µl sample)


OneDip™

96-plate: 13 minutes (18 µl mix + 2 µl sample)
384-plate: 45 minutes (5 µl mix + 2 µl sample)

Rob™ handles a 384 set-up with acceptable speed but with low investment cost.

 

Software

Our software is intuitive and simple. qPCR set-up for research and clinical applications is done by following step-by-step instructions. Several tests can be predefined on the same plate to maximize the capacity for the qPCR instrument.




Accuracy & Precision

Accuracy and precision data obtained under optimized conditions may not be possible to reproduce in your application. The data below were obtained under normal QPCR set-up conditions. On the other hand, high precision data indicates that the liquid handling is stable. Market leading precision can easily be reproduced at your lab. High precision and accuracy also grants that dispense performance is very robust. Changes in viscosity will not have the same impact on dispensed volume seen in competing systems.  So the dispense data below is what you can expect from Rob™ in reality.

 

50 µl pipette tip with filter

Volume (µl) Mean (µl) Precision (C.V.)
1 1.00 3.78
2 1.99 1.83
 5 5.00 0.76
10 10.02 0.38
Ten single dispenses in ten PCR tubes (0.2 ml).

 

50 µl pipette tip with filter, OneDip™

Volume (µl) Mean (µl) Precision (C.V.)
2 2.03 1.93
5 5.05 1.67
Three series dispenses in 3 x3 PCR tubes. Tubes were pre-filled with 15 µl master mix to mimic a qPCR set-up.



Liquid Level Detection (LLD)

It is essential to have in-process LLD and tip detection to verify processed protocols. There are two methods used to measure the liquid level heights. Either conductive or pressure based systems are used. The advantages of pressure based LLD are that all liquids can be detected and the system isn’t sensitive for static electricity. Conductive measurements require expensive conductive tips, is sensitive to static electricity but measures faster.  
Rob™ uses a further developed pressure based LLD that has improved detection speed. The LLD system provides with better precision and sensitivity than needed.

Detection limit: Detects as low 3 µl in a 200 µl PCR tube.
Detection precision: ± 0.3 µl in a PCR tube with 20 µl volume.
