恒博和泰7周年庆!!Silwet L-77 优惠供应!!!!! 本产品为拟南芥、油菜等植物转化辅助试剂,是表面活性剂的一种,是NP40转化效率的40倍以上, Silwet L-77 is a chemical mixture of polyalkyleneoxide modified heptamethyltrisiloxane (84%) and allyloxypolyethyleneglycol methyl ether (16%). It is an essential infiltration media ingredient for all Agrobacterium-based transformations of Arabidopsis and other plants.10 mL and 35 mL are sufficient quantity to prepare 33 L and 115 L of vacuum infiltration medium when used at the recommended rate of 0.03%, v/v, respectively. 原价: 分装 10ml 350元 7周年优惠价(6折销售):10ml 210元 或按原价350元(买一瓶送一瓶) SILWET L-77 is a unique surfactant designed to improve the spreading and wetting properties of pesticide spray mixes. SILWET L-77 utilizes unique organosilicone chemistry which provides the most complete coverage possible. SILWET L-77 can improve cuticular penetration of plant surfaces by the spray mix. Optimum application and resultant effects can be influenced by many factors. Consequently, it is recommended that careful observation of the spray deposit be made and adjuvant rates adjusted accordingly. Applications should be made to ensure thorough coverage without excessive run-off. Typical Properties Physical appearance Clear, light amber liquid Pounds per gallon 8.370 Specific gravity 1.0 - 1.01 pH (1.0%) 6.0 - 7.0 Freeze Point less than 35 degrees F Surface Tension (0.125% v/v) less than 25 dynes/cm Contact Angle (0.125% v/v) less than 5 degrees F Draves Wet Time (0.125% v/v) less than 15.0 seconds GENERAL PRODUCT INFORMATION (1) SILWET L-77 contains organosilicone surfactants designed to provide superior wetting and coverage. (2) SILWET L-77 can improve water penetration of hard to wet soils and provide more uniform distribution of applied moisture. (3) SILWET L-77 is generally compatible with pesticides and fertilizer solutions. (4) SILWET L-77 may cause excessive foam if not properly added to the spray tank. To minimize foam generation, add SILWET L-77 to the tank after all other ingredients are added. If foaming is still a concern, add an antifoaming agent, such as FOAMBUSTER or COMBAT PLUS to the tank prior to adding SILWET L-77. (5) Do not allow spray mixes containing SILWET L-77 to sit over 36 hours. |
