Unlike traditional air-displacement tips, these disposable units feature an integrated piston that makes direct contact with the sample fluid, entirely eliminating the air cushion. This direct-contact mechanism is essential for dispensing dense, viscous, volatile, or high-vapor-pressure liquids that would otherwise cause standard pipettes to leak or deliver inaccurate volumes. Manufactured under stringent cleanroom conditions, these specialized capillary pistons are fully sterile and completely free of DNA, RNase, DNase, and ATP. Pre-assembled and ready to mount onto Rainin Pos-D positive displacement pipettes, this consumable ensures optimal volumetric accuracy while thoroughly protecting both the user and the instrument from hazardous aerosols and cross-contamination.\u003c\/p\u003e\n\u003ch3\u003eTechnical Performance and Design\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp style=\"margin: 0;\"\u003e\u003cb\u003ePositive Displacement Mechanism:\u003c\/b\u003e The internal piston directly displaces the liquid, compensating for the physical properties of heavy or volatile fluids to ensure absolute pipetting accuracy without pressure-induced dripping.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eIntegrated Pre-assembled Design:\u003c\/b\u003e Each unit combines a precisely molded plastic capillary tube with an internal piston, eliminating manual assembly time and reducing the risk of contamination before use.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eAerosol and Cross-Contamination Prevention:\u003c\/b\u003e Because there is no air space between the piston and the sample, biohazardous aerosols and radioactive vapors are contained, entirely preventing internal pipette contamination.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eCertified Sterile Production:\u003c\/b\u003e Rigorously sterilized and certified free of biological contaminants, making them immediately deployable in highly sensitive genomic, forensic, and clinical diagnostic workflows.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eProduct Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eCatalog Number:\u003c\/b\u003e 17008605\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eVolumetric Capacity:\u003c\/b\u003e 25 ul\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eTip Technology:\u003c\/b\u003e Capillary Piston (CP) \/ Positive Displacement\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eSterility Status:\u003c\/b\u003e Sterile (DNase, RNase, and Pyrogen Free)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp style=\"margin: 0;\"\u003e\u003cb\u003ePackaging Configuration:\u003c\/b\u003e 3 Packs of 180 (540 Total Units)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eKey Benefits \u0026amp; Applications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eViscous Fluid Handling:\u003c\/b\u003e Effortlessly and accurately dispenses thick solutions like glycerol, enzyme buffers, oils, and protein mixtures that cling to the walls of standard air-displacement tips.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eVolatile Solvent Pipetting:\u003c\/b\u003e Prevents the spontaneous evaporation and subsequent dripping commonly experienced when handling high-vapor-pressure liquids such as ethanol, acetone, and chloroform.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eMolecular Biology and PCR:\u003c\/b\u003e The sterile, aerosol-free environment guarantees that trace nucleic acids are not transferred between samples, safeguarding the integrity of highly amplified PCR assays.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eCorrosive Liquid Protection:\u003c\/b\u003e Contains aggressive and caustic samples entirely within the disposable capillary tube, protecting the internal shafts and seals of the expensive positive displacement pipette.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr\u003e\n\u003cp style=\"margin: 0; font-size: 0.8em;\"\u003e\u003ci\u003eAll product names, logos, and brands are property of their respective owners.\u003c\/i\u003e\u003c\/p\u003e","brand":"Rainin","offers":[{"title":"Default Title","offer_id":49921275920636,"sku":"10913","price":200.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0627\/8463\/5132\/files\/rainin-capillary-piston-25-ul-pos-d-sterile-3-packs-of-180-pistons-pipets-pipette-tips-rainin-776346.jpg?v=1784057685","url":"https:\/\/lifesciencestrading.com\/products\/rainin-capillary-piston-25-ul-pos-d-sterile","provider":"Life Sciences Trading","version":"1.0","type":"link"}
