Topspin Silicon Microarray Printing pins

  1. 1. Datasheet for TP22 & TP38 prevents it from falling out and facilitates the alignment of the pin. The pin aspirates liquid from a well/microtiter plate by dipping the tip herein. Capillary forces draw liquid into the slot and into a closed cavity inside the pin. The closed cavity prevents evaporation of the liquid. The pin attached in the robot is then moved over the substrate and dispenses liquid when the tip touches the surface of the substrate. A single uptake can print up to 10.000 spots, and the TP22 pin prints uniformlyTP22_10 and TP22_50 homogenous, circular quality from the first to the last spot.The TOPS-PIN TP22 represents a newgeneration in microspotting pins providing Please contact us if special versions withunrivalled benefits to the customers such as: downscaled spot size are required for medium to high density arrays. • Reduced assay time • More reliable results Dimensions • Competitive pricing • Plug & play • Customisable pinsThe TOPS-PIN TP22 is designed andmanufactured with a combination of silicon andstainless steel materials. This enables the TP22to combine the durability of the silicon materialwith the “plug and play” features build in by thesteel guide.The TOPS-PIN TP22 can be used in any existingmicroarray robot on the market. The TP22 isdirectly interchangeable with existingmicrospotting pins and do not requiremodifications to the pin holder or robot.
