The PolarSafe cryogenic 2D vials, available in 2 and 5 mL sizes with internally or externally threaded caps, are idea for rapid processing of biological samples. The embedded Datamatrix code at the bottom of each vial along with the corresponding "Code 128" barcode on the body of the vial, saves time and provides accurate organization and tracking of valuable samples.

The 2D vials can be safely stored in polycarbonate boxes (purchase separately). The storage boxes also feature the 2D Datamatrix code and Code 128 barcode to provide automatic identification of both the box and stored vials.

CoolCaddy™ PCR Work Station

• Maintains 2 to 4° C for up to 5 hours
• Keeps samples cool, but not frozen
• Accomodates several different vessel types: Vials, Tubes, Strips, Plates & Reservoirs

Protect your enzymes, reagents and temperature sensitive samples with the new 5-hour CoolCaddy™.  No need for messy ice baths - simply store it overnight in any standard freezer and its ready to hold tubes, plates and reservoirs at 2 to 4° C for an entire morning or afternoon.  CoolCaddy™ is an ideal work station for PCR and especially for any protocol requiring multi-channel pipetting from a reservoir into strip tubes or 96 well plates.  And, if your work is interrupted, just place the whole CoolCaddy™ (complete with samples and reagents) back in the freezer or refrigerator until you are able to resume your experiment.

The CoolCaddy™ offers the highest level of enzyme protection and is essential for all protocols that call for more than 30 minutes of benchtop prep work.  Additionally, the proprietary refrigerant gel protects enzymes, samples and reagents from freezer fluctuations caused by power outages, open doors, and frost-free cycles.

5mL Snap-Cap MacroTubes®

• Compatible with standard equipment
• Easy-open flip top
• Syringe port in cap
• Unsurpassed Clarity
• Dual graduations at every 0.2mL and 0.5mL

5mL MacroTubes® scale up the conveniences of standard 1.5mL tubes for larger volumes. These polypropylene tubes come with an attached cap that provides a tight, leak proof seal, and can also 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 15mL tubes for compatibility with centrifuge rotors, etc. In many applications, they have replaced 15mL tubes, reducing plastic waste, storage space and shipping costs. Contamination of pipettor shafts can be eliminated because the tube length is short enough for standard 1mL and/or 5mL tips to reach the tube's conical bottom.

Dimensions: 16.5 x 54mm (not including rim and cap)

Maximum Centrifugal Force: 25,000 x g (when properly supported in appropriate rotor)

Features

• Maintains a sample temperature of less than 4ºC for almost 4 hours (with lid on rack) when used at room temperature.
• Color-change materia enables you to see how cold your samples are at a glance.
• IsoFreeze® color change racks undergo a dramatic change to a contrasting color at 7ºC.

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
• RNase and DNase free

• Available in two temperature ranges

5 mL Microcentrifuge Tubes with Snap Cap

5 mL centrifuge tubes from MIDSCI. These polypropylene tubes come with an attached cap that provides a leakproof seal and can be effortlessly opened with one hand. The cap is designed to provide a secure seal from -86°C to 180°C. In incubated, heating applications, the tube may be boiled for up to 10 minutes. A cap lock is available for temperatures above 80°C (C1005-T5-CAP). The tubes are made of maximum clarity, low-binding virgin polypropylene and are certified RNase and DNase-free. Sterile tubes are also available and packaged in bags of 10 tubes.
 
The 16 mm diameter is identical to the diameter of standard 15 mL tubes, which ensures further compatibility with centrifuge rotors and other applications. Compared to 15 mL tubes, the threat of pipettor shaft contamination is greatly reduced as the 56 mm total tube length (compared to 120 mm for 15 mL conicals) is short enough for standard 1 mL tips to reach the 5 mL tubes conical bottom.

The syringe port in the cap is not only useful for needle and syringe access but also can be useful for venting internal pressure that has built up due to incubation at higher temperatures.

• Easy flip open top
• High clarity, virgin polypropylene
• Syringe port in cap
• Compatible with standard equipment for 15 mL conicals
• Dual graduations (at every 0.5 and 0.2 mL)
