 Packaging Specifications</sup>

110158 & 110178 | 17 x 100 mm Plastic Tubes with Dual Position Snap Cap

These plastic culture tubes are produced in polystyrene (PS) or polypropylene (PP). The polystyrene tubes can withstand 1500 RPM during centrifugation. polypropylene tubes can withstand 3000 RPM and are autoclavable and freezable. Tubes with dual position snap caps (LDPE) provide either aerobic or anaerobic storage of samples. Note - Leave the dual position snap cap in the loose position for aerobic work and in the sealed position for anaerobic cultures.

110414, 110415 & 110440 | 12 x 75 mm Plastic Tubes

These plastic culture tubes are produced in polystyrene (PS) or polypropylene (PP). The polystyrene tubes can withstand 1500 RPM during centrifugation. polypropylene tubes can withstand 3000 RPM and are autoclavable and freezable. Tubes with dual position snap caps (LDPE) provide either aerobic or anaerobic storage of samples. Note - Leave the dual position snap cap in the loose position for aerobic work and in the sealed position for anaerobic cultures.

118115C | Universal Caps, Fits most 12 mm, 13 mm, & 16 mm Tubes

Guard samples against cross-contamination and laboratory work areas against infection and spillage with these universal snap caps. Precision molded from low-density polyethylene and designed to fit firmly on the tube. Closures are very sturdy under most rigorous procedures, including centrifugation.
These polyethylene (PE) universal caps are designed for easy-on and easy-off use. Cap removal is simple and quick. Universal caps are ideal for recapping most 12 mm, 13 mm and 16 mm evacuated glass blood collection tubes. Flexible closures protect from aerosols of highly infectious microorganisms. Not suitable for autoclaving.

118139 Series | Plug Stoppers for 12 mm Tubes

Polyethylene (PE) plug for 12 mm tubes and are available in a selection of colors for sample identification.

6263C | Plug Stoppers for 15 mL Centrifuge Tubes

Plug caps for 15 mL centrifuge tubes and are suitable for use with centrifuge tubes with a 17 mm diameter.

Being produced from polyethylene, they are flexible and provide better leak resistance than standard caps.

Globe Scientific Culture Tubes

• Tubes can be used for tissue culture and blood banks.
• Made from superior quality borosilicate glass to reduce pH changes and contaminants that are potentially leached from tubes made from soda lime glass.
• Tubes feature well-rounded bottoms and smooth fire-polished rims.
• Tubes are chemically inert.
• Produced in an ISO 9001:2008 certified factory.

Avant screw cap tubes and manufactured for the ultimate visibility of your sample.  They come in conical bottom or self standing/skirted and are available in a wide variety of sizes.  The tubes come sterile and DNAse/RNAse free and non-sterile.

• The AV-2***-**  and AVFS tubes are our most versatile.  With a max RCF of 20,000xg, a temperature range of -196°C to 121°C, and a silicone gasket they are great for long term storage.
•  The AVSC tubes fit all standard rotors and can be centrifuged up to 18,000xg.  They have a temperature range of -40°C to 121°C.  The silicone O ring also ensures safe storage of your samples.

Transport Tubes

• Transport tubes offer advanced seal and extended deep cap to prevent leaking when shipping samples
• Cap is designed to accommodate swab for transport, and is easily sealed or removed with a single turn
• Self-standing base allows use without racks
• Round bottom maximizes liquid retrieval and will not pinch swabs
• High-quality, medical grade virgin polypropylene is transparent for viewing samples, shatterproof, and resistant to heat and cold
• Sterilized by irradiation
• Convenient zip-closure bag is a practical alternative to folding and taping opened bags

15mL and 50 mL screw cap centrifuge tubes that are now available in individual sterile packets. Individual packets eliminate the worry of whether or not tubes in an already opened bag are still sterile and creates an ease of not having to fumble around with open bags or racks of 50 tubes. These are sterile right up until the time you open the convenient easy peel package.

The conical 15ml and 50ml centrifuge tubes are made of premium polypropylene for clarity and centrifugal strength. Tubes and caps may be frozen at temperatures as low as -86°C. The maximum centrifugal force is 12,000xg for the 15ml tubes and 15,000xg for the 50 ml tubes*. Caps have a flat top surface for easy marking and labeling.

• Sterile, individually wrapped
• RNase, DNase, and Pyrogen free
