Abstract: 2D and 3D cell culture containers formed from blends of poly-L-lactide and poly-D-lactide provide growth surfaces for adherent cells and do not require surface treatment or coating to support mammalian cell growth. The cell culture containers are transparent, heat tolerant, and are environmentally degradable and suitable for composting in landfills.

Abstract: A method for cryogenic specimen identification employs marking a stretchable pressure-sensitive vinyl label, and placing it on a storage vial or other container that can withstand a temperature of approximately ?80 degrees C. or lower, preferably contact with the liquid and/or vapor phases of liquid nitrogen at a temperature of approximately ?196 degrees C. The method includes providing a sized portion of the label that includes a waterproof soft flex vinyl facestock material containing a non-mobile plasticizer agent. The printing is also resistant to the moisture and ice that form on the container when it is removed from the liquid nitrogen. At room temperature, the label must be capable of being stretched without breaking at least 10% in both the MD and TD. Labels are sized, cut, the release liner is removed, and the label with its adhesive surface is applied to the container.

Abstract: A laboratory autography marking pen capable of delivering a low viscosity phosphorescent marking ink that contains a homogeneous suspension of phosphor particles having an average particle size of between 10 and 40 microns, and whose afterglow half-life is less than 5 minutes. The marking pen further includes a high porosity fiber channel writing nib whose ink flow channels are of a sufficient size to allow the phosphor particles suspended in the ink to flow by capillary transport through these channels onto an ink receiving substrate material.
