FAQ: Liquid flow and tubing diameter
Frequently asked questions about liquid flow, top flow rate handled by fraction collector and fractionation tubing diameter.
Liquid flow rate
What is the top flow rate that the fraction collector unit can handle?
LAMBDA OMNICOLL fraction collector and sampler is a flexible system, and it adapts to your desired application. It is not limited by the feed rate and the number of samples being collected.
You can choose the tubing and diameter as per your requirement.
Fractionation tubing diameter
What is the liquid line tubing material?
We offer PTFE tubing with the LAMBDA OMNICOLL. The tubing can be changed (type and also the diameter) which is suitable for your experiments.
What is the opening diameter of the fraction collector LAMBDA OMNICOLL?
The opening diameter of LAMBDA OMNICOLL is 2 mm (we provide Teflon tubing with 1.7 mm outer diameter to fit inside the tubing guide). You could also fix any tubing diameter onto the tubing guide (outside the tubing guide) using a suitable spiral wrap or use a heat contractible tubing.
Is it possible to use 6 mm tubing (internal diameter) as we are working with viscous substances?
It is not necessary to pass your 6 mm tubing with the viscous organic particles through the stainless steel tubing guide (cannula which guides the tubing into the test tube for collecting the sample). You can fix your tubing to the tubing guide externally with the help of spiral wraps or adhesive tape, or heat contractible tubing could be used.
