FAQ
Tubes FAQ
What tube details are needed for a quote?
Send diameter, length, capacity, cap or stopper requirement, base shape and quantity.
Are centrifuge tubes different from test tubes?
Yes. Centrifuge tubes are selected for separation workflows and often use conical bases and graduation marks.
When are connecting tubes used?
Connecting tubes are used in glassware assemblies where vapor, gas or liquid paths need T-shape, Y-shape or side-arm connections.
Can tubes be supplied in bulk packs?
Yes. Bulk packing and model-specific cartons can be quoted for laboratory distributors.
