The Snap-Cap Microcentrifuge Tube is available in five sizes, 250µl, 400µl, 500µl, 1.5ml and 1.8ml. All sizes have attached, tight-fitting Snap-Caps for optimal sealing during sample processing and centrifugation. Colours: Natural (white) for 250µl, 400µl, and 500µl. The 1.5 ml and 1.8ml sizes are available in natural and four additional colours for colour-coding.

The G-Tube Flat Top Microcentrifuge Tube is virtually transparent and far exceeds the toughness of any microcentrifuge tubes.Made of tough, clear, proprietary formulated polypropylene, the 0.6mL, 1.5mL and 2.0mL G-Tube has the same chemical resistant quality as standard tubes, but they're sturdier and virtually transparent to give a better view.

These natural-coloured microcentrifuge tubes feature a flat top cap which provides a positive and secure seal when closed, thus providing maximum protection for contents. Fabricated with virgin polypropylene for excellent chemical resistant qualities and good clarity. These tubes have high impact strength and will withstand 17000RPM and 13000 x g centrifugation.

Now there's a safe, economical way to cap and recap blood collection tubes and disposable glass culture tubes, regardless of manufacturer. Uni-Flex® Safety Caps are available for a wide range of biomedical and industrial applications. The Uni-Flex® Safety Cap liquid tight seal ensures sample integrity and prevents spillage of serum samples. Uni-Flex® Safety Caps protect your laboratory staff from the aerosols of highly infectious organisms such as TB and the HTLV-III virus.

The Hexa-Flex liquid-tight seal ensures sample integrity and prevents spillage of serum samples. Hexa-Flex Safety Caps are available in a variety of colours which helps guard against sample cross-contamination and is convenient for colour-coding to particular R&D projects. Hexa-Flex Safety Caps protect your laboratory staff from highly-infectious organisms such as TB and the HTLV-III virus.

These Thin-Wall Micro Reaction Tubes are designed for use with 96-well Thermal Cyclers. These tubes provide optimal contact with the sample block ensuring optimal heat transfer.

Bio Plas brand 0.5mL PCR tubes which are made of virgin polypropylene. These thin-wall reaction tubes are designed for use with 96-well thermal cyclers. Extra thin wall design is almost transparent for better viewing of contents and ensures rapid thermal transfer. This ensures a significant reduction in cycle and PCR reaction time. Tubes have attached snap-caps that "click" to let you know there's a good seal. Non-sterile. Autoclavable at 121°C.

The Siliconized G-Tube is built for high impact usage and will withstand over 30,000 x G when spun. Thicker walls make this the tube of choice for extreme stress, high spinning speeds, boiling, chemical resistance and freezing. This series can withstand temperature ranges of -80 to 121°C (-112 to 250°F).

The extraordinary strength, safety and reliability of the Screw-Cap Microcentrifuge Tube lets you perform procedures that simply can"t be done with other tubes. Spin it, store it, transport it (even by air). Boil it, irradiate it, immerse it in the vapour phase of liquid nitrogen-it"ll stand up to the test!
