Technical background screw cap tubes (-200°C to 110°C)

BIOplastics Screw Cap Tubes are an excellent means of storage. They are made of polypropylene, with frosted writing areas and with a plain, homogeneous surface at the inside. Screw Cap Tubes are catagorized into three different volumes: 0.5 ml, 1.5 ml and 2.0 ml. Screw Cap Tubes are available as conical or free standing and sterile as well as non-sterile. The screw cap tubes have a working range of -200°C to 110°C and can be centrifuged up to 20.000 g.

Colored screw cap tubes and colored screw caps

The marketplace uses natural colored screw cap tubes with colored caps. In some cases screw cap tubes are used with the caps attached to the tubes to prevent contamination of similar tubes by means of mixing up caps. However pipetting with an attached lid is not optimal since the spacing of tubes, the overall footprint, and the chance of touching the inner part of the cap are all major drawbacks. To overcome these drawback and prevent cross contamination, we have not only colored our screw caps but also offer screw cap tubes in 10 different colors. BIOplastics is the first company in the world offering COLORED SCREW CAP TUBES AND COLORED SCREW CAPS which enable not only a wide variety of color coded combinations (colored tube and colored cap) but also significantly reduces the chance of cross contamination caused by mixing up incorrect colored cap to tube closure.

OLD TRADITIONAL SCREW CAP TUBES AND CAP WITH O-RINGS

A: Rubber ring, may contaminate your sample, dissolves in organic solutions, become brittle in time and may break at lower temperatures
B: Inner cylinder sitting in the tube and causing loss of sample, inconsistency of result and increases contact sample to tube surface
C: Cavity number inside the cap: source of binding and contamination

SCREW CAP TUBES AND CAPS WITH SMART SECURE CLOSURE TECHNOLOGY

A: Smart closure, avoids sample contaminate, withstands organic solutions, remains soft at extreme low and high temperatures
B: Absence of cylinder sitting in the tube assures maximum sample recovery, consistency of result and decreases contact sample to tube surface
C: Cavity number outside of the cap avoids binding and contamination

Tube and cap facts. Why and how it works better for you.

Triangular cap:
- Decreases chance of rolling away
- Easy handling & holding in hand

Smart closure:
- Remains soft at extreme low and high temperatures
- Enables the use of organic solvents
- Assures no leakage

Absence of cylinder sitting in the tube:
- Assures maximum sample recovery, consistency of results and decreases contact sample to tube surface

No logo at inner side of cap:
- Avoids sticking of molecules in corners and reducing total contact surface

Secure closure and easy closure cap range for screw cap tubes

Screw caps for screw cap tubes are offered in two selectable versions: The regular Secure Closure and the new Easy Closure Screw Cap. For robust applications such as long term storage: ≥ 3 years below - 80 °C or incubation at ≥ 95 °C for ≥ 2 hours, one should opt for the regular Secure Closure Caps. For less robust applications: ≤ 3 years higher than -80 °C or less stringent incubation ≤ 100 °C ≤ 1.5 hours, one can opt for the Easy Closure Cap. Both types of caps incorporate BIOplastics’ non leaking Smart Closure Cap Technology. The Easy Closure Cap is produced from a completely different material. All types of screw caps and screw tubes are offered in 10 different colors, DNase. RNase, Pyrogen, Metal and ATP free.

Titer dilution storage tubes and systems (-200°C to 110°C)

Dilution storage tubes and systems are designed for multi purpose usage. The tubes are extra robust, can hold 0.5 ml, have an extraordinary working range of -200°C to 110°C and can be centrifuged up to 20.000 g. The tubes are availabe in a single version, an 8 strip version, as well as a 96 well version. All tubes can be stored in the BIOplastics regular Work Rack S-96 System. All tubes can be closed using the extra robust EU Indented Flat 8 Cap-Strip (B75701), Indented Flat 12 Cap-Strip (B56501), and EU Indented Flat Cap Plate 96 Format (B57501).

Uniquely coded strip-tubes and tube plates

Using BIOplastics BPLPM technology, products can be individually and uniquely coded. The regular titer dilution and storage tubes already contain the BPLPM technology mix. These products can be laser coded by YAC laser, which also allows BIOplastics to offer uniquely coded strip-tubes and tube plates. Each tube has a unique, in product labeled, non removable ID#. Specific codes or customized marked products are available on demand.
