LiteSafe™ Centrifuge Tubes

These tubes are completely opaque, therefore protecting even the most light sensitive compounds. Midsci LiteSafe™ tubes eliminate the inconvenience of fitting tubes with aluminum foil to protect samples. Ideal for use with fluorescent probes or ethidium bromide.

Disposable polypropylene tubes and caps with recessed lid to prevent leaking. Frosted writing surface allows for permanent identification and labeling. Autoclavable to 122°C and can be stored in freezers to -100°C.

RCF values: 15mL, 8,400g

Nest 250 and 500 mL Centrifuge Tubes

The 250mL and 500mL centrifuge tubes can process a large number of samples at one time and are suitable for separation and harvest of large cells, supernatants, bacteria, yeast and tissue samples, therefore they are widely used in the field of life sciences and clinical experiments and can meet the requirements of biological analysis.

Large centrifuge tubes are perfect for clarifying large volume solutions or concentrating live cells in tissue culture. Made from pure pre-tested medical-grade resins to ensure the integrity of your work. Each lot is tested and certified free of RNase/DNase, Endotoxins, and is non-pyrogenic. Resins are pre-tested, and are free of ATP, Oleamide, DiHEMDA, and Phthalates. These tubes come in unique balanced packages of 2 tubes, so you don’t have to worry about resealing bags or re-sterilizing these tubes. They also include our exclusive caps with an integral elastomeric sealing ring that eliminates leaking. Sterile tubes have been sterilized with a validated medical-grade process using radiation.
 

Ideal for storage of buffers, reagents, and other solutions.

• Single piece lid and tube available in conical and self-standing bottoms
• Tab on lid enables convenient one-handed opening
• Lid audibly snaps closed, and opens with a "pop!" so you know when it is sealed
• Ideal for sample storage, collection, and experimental procedures

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
• Easy peel wrappers
• Flat, markable screw caps

• Spin up to 70,000 x g
• Disposable - avoid potential contamination from reusing tubes
• Capped tubes have frosted surface for easy labeling
• Sterile

Multi-Purpose Test Tubes 12 x 75 mm 
 
Precision-molded from premium-grade plastics and ideal for routine laboratory analysis and procedures. We have applied the lessons learned from over 27 years of manufacturing experience to produce tubes that perform at their highest level. Our tubes are rigorously inspected by our Quality Assurance Department to ensure they surpass our exacting specifications. These tubes are ideal for a wide range of laboratory applications. They are available in several sizes, and from three materials, to meet a variety of needs.

• - All of the tubes are plastic (polystyrene, polypropylene or polypropylene-copolymer), thus preventing the problem of broken glass.
• - Polypropylene is chemically resistant, autoclavable and virtually unbreakable.
• - Polystyrene is clear like glass.

Note that caps are ordered separately. These tubes are not available sterile.

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.
