0.5ml Extended Screw Cap Tubes with Looped Caps (with O-ring), Self Standing, Non-Sterile, Unassembled

NOVASBIO screw cap microtubes serve a wide range of laboratory needs including collection, processing, centrifugation, long-term storage and packaging/shipping of restriction enzymes and other reagents.

The closure on NOVASBIO Screw Cap Tubes includes an ‘O’ ring that is formulated and manufactured from a specially selected material which is resistant to many commonly used laboratory chemicals. The threaded ‘O’ ring design of the cap ensures a uniform closure allowing centrifugation up to 20,000 RCF. Caps, available in 5 colours or clear, feature a syringe port which is easily pierced for radioisotope labelling and fraction collecting. Ribs are designed to facilitate single-handed opening and closing, even with gloves on. The Orientation Tab allows the microtube to be aligned with the centrifuge rotor for multiple applications, including desalting. This ensures that the microtube can be re­spun without disturbing the partially pelletised sediment.

NOVASBIO screw cap microtubes are available as combined products comprising Tubes and Caps (SCT-). When ordered as non- sterile, both Tubes and Caps are Un-Assembled, supplied together but packed separately. For the sterile option, Tubes and Caps are Assembled and packed in convenient bags of 100. Tubes (ST-) and Caps SC-), are also available as separate products, Individually Packed.

The Looped Cap (-LP) option ensures that the cap remains attached to a specific tube and so prevent cross contamination.
