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.

PR1MA™ Transport Tubes with Temperature Indicator

Leak-Proof, 95kPa Compliant, Temperature-Indicating Sample Vials.

PR1MA™ Self-Standing Transport Tubes—commonly known as mailing tubes or transport vials—are specifically engineered for the safe storage, transport, and freezing of temperature-sensitive biological samples. Made from virgin polypropylene, these tubes are RNase, DNase, and pyrogen-free, ensuring contamination-free use in medical, clinical, pharmaceutical, and research settings.

Five-O™ 5 mL MacroTubes^® - Opaque Black

The 5 mL Five-O MacroTubes take all of the conveniences of standard 15 mL conical tubes and scale them down for space efficiency and decreased natural resource consumption. Useful from -86°C to 110°C, these tubes are a valuable resource for boiling and for sample preservation at very low temperatures. Additionally, the 56 mm length (vs. 120 mm for 15 mL tubes, greatly reduces the risk of contamination of pipettor shafts, allowing 1 mL or 5 mL tips to easily reach the bottom.

The foam racks are similar to the packaging normally associated with 15 mL tubes (upright with caps attached), but they require about 60% less storage space.

• Opaque Black Tube
• Compatible with standard equipment
• Centrifuge at up to 25,000 x g
• RNase, DNase & pyrogen free
• Unsurpassed Clarity
• Dual graduations at every 0.2 mL and 0.5 mL

TotalPure™ Metal Free Centrifuge Tubes

Total-Pure™ Centrifuge Tubes are produced from a proprietary purified polypropylene blend that is certified to be free of trace metal content. Tested via ICP-MS, these tubes are certified to contain less than 1ppm of common trace metals including: Calcium, Magnesium, Zinc, Iron, Manganese, Copper, Aluminum, Silicon, Nickel, Vanadium, Sodium, Phosphorous, Cobalt, Chromium, Potassium, Lithium, Lead, Selenium, Cadmium, Mercury, and Arsenic.

In addition to a superior level of purity, TotalPure™ Tubes include a wide array of premium features. These tubes are engineered to withstand a max centrifugation rate of 20,000 x g, with this RCF specification printed directly on both the 15 mL and 50 mL tubes. These tubes also feature Hi-Viz™ graduations that are easily identified at any angle and the printed max-freeze line indicates the maximum allowable volume to be frozen inside the tubes. TotalPure’s natural color caps offer a smooth seal that is easy to open/close with one hand without compromising the integrity of the 95kPA leak-proof seal.

• Ultra-Pure Polypropylene Blend Certified Free of Trace Metals
• Hi-Viz™ Graduations with Maximum Freeze Capacity Line
• Resealable Zip Bags of 25 Tubes, or Individually Wrapped
• E-Beam Sterilized (SAL 10-6)

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 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).

Specifications

• Compatible with standard equipment
• Withstands up to 25,000 X g
• Dual graduations (at every .2mL and .5mL)
• Unsurpassed clarity

• 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.

MacroTube® Vivid™ 5 mL Tubes

Sterile, Ultra-Clear Tubes with Vivid Printed Graduations.

MacroTube® Vivid™ tubes are designed for precision, visibility, and purity in every lab application. Made from ultra-clear polypropylene, these high-quality laboratory tubes feature bold, vividly printed graduations for easy and accurate volume measurement. Ideal for researchers and technicians who need reliable, contaminant-free performance, each tube is certified RNase, DNase, and pyrogen-free.

Packaged sterile in resealable bags, MacroTube® Vivid™ tubes provide convenience and contamination control. Each set is housed in snap-apart racks (2 x 25 tubes) for quick access, efficient organization, and minimized waste.

Key Features

• Vivid, easy-to-read printed graduations for precise measurement
• Made from ultra-clear polypropylene for superior sample visibility
• Certified RNase, DNase, and pyrogen-free
• Sterile tubes packaged in resealable bags
• Snap-apart racks (2 x 25) for convenience and storage flexibility

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)
