0.2ml Thin Wall PCR Tubes

Our 0.2ml microtubes for PCR are made of high quality virgin polypropylene and feature thin walls for accelerated heat transfer. Biotix microtubes are compatible with most leading thermal cyclers. Tubes and caps are autoclavable and available in six different colors.

0.2ml PCR Microtube 8 Strips with attached caps

The 0.2ml PCR 8 Strip Microtubes with attached caps feature a uniform thin-wall design for accelerated heat transfer and short cycling times. Product features a dome shaped cap to ensure adequate contact with the lid of a thermal cycler. Attached caps resolve concernswith cross contamination that may come from the misalignment of strip caps.

The microtube strip’s distance from tube to tube is compatible with standard 96 well heat blocks. These strip tubes are composed of virgin polypropylene and are fully autoclavable (121°C, 15psi for 15 minutes).

0.2ml & 0.3ml Microtube & Tube Cap Strips

The 0.2ml PCR 8 or 12 Strip Microtube with detached cap features the same uniform thin wall design for accelerated heat transfer and short cycling times as our attached cap strips, catalog # 3428.8. Sold separately, our strip caps (Catalog # 3427.8) incorporate the dome shape to ensure an adequate seal with the thermal cycler lid. Detached strip caps provide peace of mind because they are disposable and allow for a fresh cap strip after each tube opening.

Product is manufactured from virgin polypropylene and is compatible with standard 96-well heat blocks. *Autoclavable (121°C, 15psi for 15 minutes).

0.6ml Thin Wall PCR Tubes

Specially designed for PCR, our 0.6ml tubes features uniform micro-thin walls for efficient heat transfer and fast cycling times.The unique cap provides a no leak seal which prevents evaporation during cycling, but still remains easy to open. Sterile products are packaged as one zip-lock bag containing 10 heat sealed bags of 100 tubes each

0.6ml Microcentrifuge Tubes

These flat cap graduated tubes are frosted on top and side for convenient sample identification. Graduation at 0.1, 0.2, 0.3, 0.5 and 0.6ml make them ideal for many uses. Sterile product is packaged in a zip-lock bag containing 10 sealed zip-lock pouches of 100 tubes.

1.6ml Microcentrifuge Tubes

With graduation at 0.1, 0.5, 1.0 and 1.5ml, a frosted flat cap and side, these microcentrifuge tubes makes sample identification a snap. Our microtubes are available in S³ low retention polymer for ultra low sample adhesion.

Sterile tubes are packaged in a zip-lock bag, containing 10 sealed zip-lock pouches of 50 tubes each.

2.0ml Graduated Microcentrifuge Tubes

This 2.0ml graduated microcentrifuge tube features labeled graduations at 0.5, 1.0, 1.5 and 2.0ml for volume verification. The tube’s cap and side are frosted for sample labeling. The cap incorporates a 0.28mm piercing port that is located in the center of the cap for sample removal. Sterile tubes are packaged in a zip-lock bag containing 10 heat sealed bags of 50 tubes each.

Screw Cap Microcentrifuge Tubes

Neptune™ brand screw cap microcentrifuge tubes with an O-ring seal cap ensure a positive leakproof seal, time after time, retaining sample integrity under even the most adverse conditions. They are ideal for freezer storage, centrifugation and they fit most standard microcentrifuge rotors.

Cryotubes vs Standard Tubes
Standard screw-cap tubes use neoprene O-rings and are designed for general laboratory use down to -80°C. Below this temperature the neoprene fails to offer an effective seal. Cryotubes and vials feature special thread designs, higher grade polymers, and silicone O-rings to ensure secure long term storage for your precious cell cultures.

Cryo Vials

Tube are designed for the storage of biological material at temperatures as low as -190ºC, but should be stored in the gas phase of liquid nitrogen. The cap features a long skirt for one hand aseptic techniques, and our thread design allows tightening or removal with a mere 1 1/4 turn. A specially designed lip inside the cap ensures a leak-proof seal. The cap and tube are made of virgin polypropylene with matched thermal coefficients to further ensure leak proof performance.

Cryotubes vs Cryovials
Cryovials are the traditional storage container and come in 5 sizes including large volume 3-5ml vials. Cryotubes feature the same dimensions as standard screw-cap tubes and a centrifugation collar for easy spins. The smaller diameter also allows you to store 19 more samples per standard cryo box. Both cryostorage containers feature medical grade silicone O-rings and other features to ensure secure long term storage of your precious cells.

Liquid vs Vapor Phase Storage
All cryogenic containers are designed for vapor phase storage, but can withstand contact with liquid phase nitrogen. We advise against routine liquid phase storage because of the phase change explosive potential of liquid
N₂ when exposed to room temperatures.

Cryo Tubes

Biotix’s cryotubes offer significant advantages over traditional cryovial storage, and at a lower price! The smaller outside diameter and molded spin collar allows for use in standard microcentrifuge rotors, so you can spin, resuspend and freeze all in the same tube. You can store 100 tubes in the same space as 81 cryovials. Manufactured from virgin grade polypropylene with silicone O-rings to seal at all temperatures. Biotix’s cryotubes are not just another screw cap tube, but a revolutionary cryostorage solution. Where else can you get more for less?

15 & 50ml Centrifuge Tubes

Neptune™ brand 15 and 50ml Centrifuge Tubes are manufactured from virgin polypropylene and are designed to handle the rigors of everyday lab work. Tubes feature easy to read graduation marks and ample writing space that measures 20mm wide by 50mm in length.

The 15ml tube has black graduation markings from 1.5 to 15ml and is centrifuge speed rated to 6,000 RCF. The 50ml tube has graduation markings for measurements of 5-50ml and is centrifuge speed rated to 9,400 RCF. All tubes include a flat top rim seal cap manufactured from highdensity polyethylene. The top of the cap has a frosted writing surface for labeling. Biotix’s engineers incorporated large ridges for increased grip when wearing gloves and a 3/4-turn closure, thereby increasing speed and allowing for one-handed operation.

Available in bulk or
racked configurations

Mini-tube System

This system provides you with pre-racked 1.1ml strip minitubes in standard 96-well format. This is an ideal system for microplate to tube transfer or manual to robotic process transfer. The Minitube System provides you with pre-racked 1.1ml, 8 strip minitubes; an ideal system for microplate to tube transfers or manual to robotic process transfer.

The system features a standard 8 x 12 format for convenient, multichannel pipetting, and the alpha-numeric labeled, non-reversing rack and lid ensure positive sample identification. Condensation rings above each tube minimize cross contamination between wells, and the system is completely autoclavable (except for optional mini-cap strips). The rack base is fully compatible with all popular robotic instruments.
