DuoClick™ Two Position Screw-Cap Culture Tubes

• New patent pending screw-cap!
• Aerobic culturing at first click
• Anaerobic after second click
• Printed graduations
• Flat, markable screw-cap

DuoClick™ tubes feature a unique, patent pending screw closure system. DuoClick™ tubes completely eliminate the excess force, splashing and general frustration of traditional snap-cap culture tubes. The advanced cap design includes two distinct positions for aerobic and anaerobic culturing. Just rotate the cap 1/4 turn to the first click to secure the cap in the aerobic position. Or, rotate it another 1/2 turn past the second click for a leakproof, airtight seal for anaerobic culturing.

DuoClick™ tubes are available gamma sterilized, with screw caps attached, and in our exclusive ready-to- use rack packaging. Polypropylene tubes can be centrifuged at up to 4,000 x g.

TPP PREMIUM Conical 15 and 50 mL Centrifuge Tubes

"No more cracking at -80°C or buckling during spins!"

TPP Premium Conical Centrifuge Tubes are designed for exceptional performance that surpasses standard 15 mL and 50 mL conical tubes.

Ideal for aliquoting and centrifuging reagents

• Freezing & boiling proof
  
• Tubes and Caps are manufactured to withstand equivalent centrifugal force, thus eliminating abnormal tube buckling
  
• Screw Caps are designed with pronounced internal grooves
  
• Gas and Aerosol tight
  
• Enables a fitted seal to prevent leaking during spinning, transportation or storage
  
• Protects sample integrity by reducing contamination
  
• Graduations all the way down to 0.1 mL (for 15 mL tubes/ 0.5 mL for 50 mL tubes)
  

• Manufactured with the highest quality of virgin raw materials
• Minimizes sample interaction with the centrifuge tube material while preventing leaching that decreases sample integrity
• No additives, slip agents, biocides or plasticizers are utilized in the manufacturing process
  

•  On top of cap - promotes easy identification of tubes in rack
• On side of tube - permits detailed description labeling

• Centrifugation  & Storage - 15 & 50 mL PP conical tube , 15 mL PS conical tube and 13 mL PS flat tube
• Media filtration & Storage - 50 mL PP skirted tube
• Cell line cryovial freezing in isopropanol bath - 15 mL PS conical tube

Quality Assurance

Culture Tubes

• Available in Polypropylene or Polystyrene
• Dual-position snap Caps attached or ordered separately
• Molded graduations on attached cap versions
• Sterile, RNase, DNase, pyrogen, and cytotoxin free
• Compatible with all standard equipment

These culture tubes are available in both 12 × 75 mm (5 mL) or 17 × 100 mm (14 mL) capacities. Low-density polyethylene (LDPE) snap caps can be attached in two positions. The first position allows for the flow of air both in and out of the tube enabling aerobic culturing. The second position offers a leak-proof and air-tight seal making it ideal for anaerobic culturing and/or sample storage.

The tubes are available in two plastic polymers. Crystal clear polystyrene (PS) tubes withstand temperatures from 0°C to 70°C, while durable transparent polypropylene (PP) tubes withstand temperatures from -86°C to 121°C.

Tubes are available with caps attached and printed graduations or without caps and graduation-free. Polystyrene tubes may be centrifuged at up to 2000xg. Polypropylene tubes withstand higher centrifugal forces, up to 4000xg.

All tubes and caps come sterilized to SAL 10-6 and are RNase, DNase, pyrogen, and cytotoxin-free.

FlowTubes™ for Flow Cytometry Instruments

• Compatible with FACS instruments
• Available with 35 um strainer cap, standard cap, or no cap
• Clear polystyrene
• 5 mL capacity
• 12 x 75 mm

Designed for Fluorescence Activated Cell Sorting / flow cytometry equipment. To ensure consistent compatibility with the automated instrument, the diameter and wall thickness is held to very tight tolerances. The tubes are available with the standard two-position culture cap, no cap at all, or with a cap that contains a 35 um nylon mesh screen. These tubes are primarily used to collect dissociated samples for subsequent processing in automated flow cytometry instruments.

 
Cell Strainer Caps

These cell strainers are ideal for detaching, isolating and straining cells from clusters and tissues. Their built in compatibility with 12 × 75 mm culture tubes and FACS tubes makes them especially useful for pre-sorting and preparing samples for fluorescence-activated cell Sorting (FACS). Typically, a 35 um porous mesh is used to obtain a single-cell suspension and to prevent clogging in FACS instrumentation. However, a multitude of FACS users have cited applications requiring finer pore sizes for a higher level of anti-clog protection. Others require a larger pore size for pre-sorting and/or for more efficient rapid flow. 

• Color coded by pore size
• E-Beam sterilized (SAL 10 -6)

5 mL Snap-Cap MacroTubes®

• Compatible with standard equipment
• Easy-open flip top
• Syringe port in cap
• Unsurpassed clarity, virgin polypropylene
• Dual graduations (at every 0.2 mL and 0.5 mL)
• Certified RNase and DNase-free.

5 mL MacroTubes® scale up the conveniences of standard 1.5 mL tubes for larger volumes. These polypropylene tubes come with an attached cap that provides a tight, leak-proof seal and can be opened (or closed) with one hand. The cap is designed to provide a secure seal from -86°C to 80°C.

They have the same diameter as standard 15 mL tubes for compatibility with centrifuge rotors, etc. They have replaced 15 mL tubes in many applications, reducing plastic waste, storage space, and shipping costs. Contamination of pipettor shafts can be eliminated because the tube length is short enough for standard 1 mL and/or 5 mL tips to reach the tube's conical bottom. The syringe port in the cap is useful not only for needle and syringe access but also for venting internal pressure that has built up due to incubation at higher temperatures.

Dimensions: 16.5 x 54 mm (not including rim and cap)
Maximum Centrifugal Force: 25,000 x g (when properly supported in the appropriate rotor)

5 mL Microcentrifuge Tubes with Screw Cap

The tubes are made of high clarify, low binding virgin polypropylene and are certified RNase/DNase free. The 16mm diameter is identical to standard 15mL tubes, thus ensuring compatibility with existing centrifuge rotors. Other equipment, specially designed for 5mL tubes is available.

The MacroTubes are suppled with 20mm(OD) caps that seal smoothly and completely with a single 360° turn. Useable from -86 °C to 110 °C, they are a valuable vessel for boiling and low temperature sample preservation. Choose from non-sterile bulk packaging, or sterile rack packaging (upright in foam racks with caps attached).
