 | Filter samples in microcentrifuges Spin-X centrifuge tube filters utilize centrifugation for the filtering of small volumes. The unit consists of a polypropylene filter insert and a centrifuge tube. It handles volumes up to 500µl. they have a cellulose acetate membrane for aqueous solutions which is ideal for the removal of bacteria, particles, and cells from media. They are also effective for DNA removal from agarose or acrylamide gels. |

 | These rugged Polypropylene Centrifuge Bottles are suitable for low to moderate speed centrifugation when filled to 80% of their nominal capacity. Re-usable and autoclavable, the bottles are designed with leakproof linerless closures. Bottles are molded with consistent wall thickness for excellent performance and have excellent chemical resistance.
Features
- Consistent wall thickness for low to moderate speed centrifugation
- Polypropylene (PP) bottle and cap with integral seal ring for leakproof closure
- Bottle must be filled to 80% of volume for proper performance
- 250 ml Bottle - 27,500 x g
- 500 ml Bottle - 4,800 x g
- Re-usable and autoclavable at 121°C
- Excellent chemical resistance |
 | Conical 15 ml and 50 ml centrifuge tubes are made of premium polypropylene for clarity and centrifugal strength. They are supplied sterile, and although they are autoclavable, their polyethylene screw caps are not. Tubes and caps may be frozen at temperatures as low as -45°C. The maximum centrifugal force is 12,000 xg for the 15 ml tubes and 15,000 xg for the 50 ml tubes*. Caps have a flat top surface for easy marking.
The Free Standing tubes have a "skirted" bottom that allows the tube to stand upright without a separate test tube rack.
- Sterile, RNase, DNase, pyrogen and cytotoxin free
- Available racked or bagged
- Compatible with standard rotors
- Frosted marking surface
*Refers to liquids with a specific gravity of 1.0, using appropriate rotors, cushions and adapters. |
 | Designed by Dr. J.P. Chang for the embedding of a monolayer of cells. This specially designed mold has proven useful in the processing of frozen sections, ascite cells, fresh imprints, as well as blood and marrow smears. J. of Ultrastructural Res., 37, 370 (1971). |
 | Relied on to transport dust samples from the moon - Ideal for small quantities of liquids or solids - Made of injection-molded polyethylene - Screw caps feature a leakproof inner seal - Easy to clean |
 | The tips on these applicators are specially designed to withstand many of the chemicals and solutions commonly use in labs and clean rooms. Tips are resistant to deterioration – they won'’'t swell or break apart. |
 | The Chessy test specimen comprises more than 1.6 million gold squares on silicon which form a four-fold chequerboard pattern in an area of 5mm square. Overall Size of specimen is 10 mm x 10 mm each |
 | A two-directional mold that allows for single embedded specimens to be sectioned both laterally and transversely. Tissues to be embedded are accurately trimmed and placed so that both sides of the tissue are against both edges of the cavity tip. Chien, K., et al. (1985) Proc. Ann. EMSA Meeting 43, 460 |
 | Rapidly Cool Agarose Mixtures and Other Solutions
Quick – Chill molten agarose down to 60°C in minutes
Improve Results – Rapid cooling of agarose prevents an early-polymerized layer on top of the solution, which interferes with results
Versatile – Use ChillDown whenever cooling of solutions is desirable
Universal – Fits any 250ml beaker
Easy-To-Use – Simply leave your ChillDown in the freezer overnight and it will be ready for you when you need it
