Light Labs Introduces NEW Metal Freezer Racks
http://www.lightlabsusa.com/
Light Labs is proud to introduce our new line of metal freezer racks which can be found on our website at http://www.lightlabsusa.com. Our new metal freezer racks come in hundreds of different shapes and sizes and are designed to fit a wide range of laboratory freezers. The new metal freezer racks from Light Labs are constructed of high-quality, corrosion resistant stainless steel. Several configurations are available for both 2" and 3" high storage boxes. Light Labs now offers storage boxes for microcentrifuge tubes, which are made of either cardboard or polycarbonate plastic.
Eight Questions Reaserchers Need to Ask About Their Tissue Culture Flasks
http://www.lightlabsusa.com/
1. Do the membranes in your caps clog when wet? Our membranes have hydrophobic qualities so that clogging is prevented.
2. Do you know if your cap is opened enough to vent? When a cap is open too far or not open enough, it isn't good for the cells. When the TPP vented caps are loosened a 1/4 turn there is a "catch" you can feel and hear. There is also a visual guide; the bar on the cap will line up with the "T" bar on the flask. These are designed for optimal venting and to eliminate the variable of variation in gas exchange between multiple flasks.
3. How do you know if your filtered cap (cap w/membrane) is closed tight enough? You will notice a "T" molded into the TPP flask on the top near the flask opening. You will also notice a solid "bar" on the cap. On the filtered caps the "bar" lines up with the "T" on the flask to let a researcher know the cap is in the closed position. With our competitors there isn't a guide to help them, so once in awhile a researcher will really crank the caps on tight. This can cause the flask to crack and actually ruin an experiment.
4. What percentage of cells do you retrieve from your flasks? Using a 1ml pipette or 24cm cell scraper and a T75 TPP Flask you can get to every corner without any difficulty. This also means that 100% of the media, FBS, etc. is going to treating cells/tissue in a TPP flask. If a lab can only retrieve 80% of their cells that means that 20% of everything put inside that flask is wasted material. That gets real expensive!
5. Do you ever find it hard to read the graduations on a flask? Most other manufacturers have clear graduations on their flasks. These flasks are very hard to read under the intense light of a bio-safety hood or when there is media in the flask. TPP graduations are in white making it easy to read for improved measuring & reduced potential for eye strain.
6. Do you ever find flasks on their side or tipped over in the incubator? When carrying a stack of flasks, does one ever slip out and fall to the floor? While many manufacturers have rimmed tops for better stacking & for better carrying of multiple flasks, most of these rims are ineffective. The rims on our TPP flasks are much more pronounced and thus more effective.
7. Do you ever have flasks stick together in the incubator? Flasks may stick together in an incubator because of condensation. TPP flasks have venting grooves on the bottom to allow even gas flow between stacked flasks, this prevents condensation build up. The vent grooves also eliminates stacked flasks from insulating each other by allowing heat exchange between stacked product.
8. How would you like a flask that takes up less space but has the same growth surface? Notice on the TPP flasks how the growth surface starts just below the neck. On other flasks, you have a slanted area between the growth surface and the neck. This is wasted space and provides no advantage to the lab.
