Screw Cap Tubes are ideal for long term use in a variety of situations. Manufactured to the most rigid standards, these can be used in extremes of temperature: from vapor phase liquid nitrogen through to boiling applications. The cap and O-ring are designed to be the perfect complement to the screw tube, thus ensuring a perfect seal. When the naturally low-binding properties of the virgin polypropylene are combined with the leak free seal and certified from DNase, RNase and DNA, then these provide the ideal long-term storage solution. For your convenience, we also provide styles of tubes with graduations at 100uL intervals with writing patches.
