flasks

Avantor offers a wide variety of flasks to meet your labware needs. Select pear shaped, round bottom, flat bottom, Kjeldahl, conical or Erlenmeyer flasks in a variety of capacities. Perform specialized procedures with distilling, rotary evaporator, filter and iodine flasks. Volumetric and nitrogen flasks safely store and measure liquids and gases. Meet your lab's cell culturing needs with trypsinizing, culture, and spinner flasks. Most flask types feature borosilicate glass construction; some offer plastic models as well. Purchase flasks in cases, packs, or individually.

Cell culture flasks, cell-repellent surface, CELLSTAR®

Supplier: Greiner Bio-One

These sterile, PS cell culture flasks have a cell-repellent surface to effectively inhibit cell attachment. Achieved through a chemical polymer modification, the surface does not degrade or leach under common cell culture conditions, rendering an ideal substrate for native cell culture experiments.

Poly-D-Lysine flasks, Corning® BioCoat®

Supplier: Corning

Poly-D-Lysine (PDL) and Poly-L-Lysine (PLL) are synthetic compounds that enhance cell adhesion and protein absorption by altering surface charges on the culture substrate. In addition to promoting cell adhesion, poly-lysine surface treatments support neurite outgrowth and improve the survival of many central nervous system (CNS) primary cells in culture. As PDL and PLL are synthetic molecules, they do not stimulate biological activity in the cells cultured on them, and they do not introduce impurities carried by natural polymers.
