209221 HAMILTON 汉密尔顿实验室针22 gauge 小 Hub 可移除 CTC 针头（PN:209221）

209221 HAMILTON 汉密尔顿实验室针22 gauge 小 Hub 可移除 CTC 针头（PN:209221）产品详情介绍

品牌：HAMILTON（汉密尔顿）
型号：209221
产品定位：CTC/LEAP PAL 自动进样器专用针头，22 gauge 超细规格 + 钝头设计，专为实验室自动化进样场景定制

（一）产品核心信息

HAMILTON 209221 是一款22 gauge 超细规格的小 Hub 可移除 CTC 针头，仅适配 CTC/LEAP PAL 自动进样器专用注射器，不兼容 HAMILTON 标准小 Hub（Small RN）注射器。

产品为固定规格：长度 50.8mm（2 英寸），针尖为 Style 3 钝头设计，每包含 3 支；采用 304 不锈钢精密制造，支持高压灭菌，主打自动进样过程中的 “精准适配 + 低损伤 + 防堵塞”，是实验室自动化样品处理的核心耗材。

（二）核心优势

1. 自动进样器专属适配，避免错配风险
   针体与 Hub 结构经 CTC/LEAP PAL 自动进样器注射器专项校准，连接间隙≤0.01mm，确保自动进样时无晃动、无漏液；明确标注 “不兼容标准 Small RN 注射器”，帮助用户精准选型，减少采购错误。
2. 22 gauge 超细 + 钝头设计，双重保护
   • 超细规格：22 gauge（外直径 0.71mm，内直径 0.41mm）适配微量自动进样需求，减少样品吸附残留；
   • Style 3 钝头：针尖圆润无锋利边缘，既能降低进样隔垫的穿刺损伤（延长隔垫使用寿命 30%），又能避免吸样时吸入微小颗粒导致的针头堵塞，提升自动进样稳定性。
3. 小 Hub 低死体积，自动化精度拉满
   小 Hub 结构可精确对准自动进样器注射器 “零刻度线”，死体积≤0.05μL，配合自动进样器的精密驱动，显著降低进样体积偏差（RSD≤0.1%），尤其适合痕量分析（如农药残留、环境污染物检测）。
4. 304 不锈钢耐用性，适配自动化高频操作
   医用级 304 不锈钢针体耐酸碱、耐有机溶剂（如乙腈、甲醇），机械强度优异，可耐受自动进样器的高频穿刺（单支可支持 500 次以上进样）；支持121℃高压灭菌，重复使用 5 次以上仍保持密封性能，降低自动化实验耗材成本。

（三）适用场景

• 实验室自动化场景：
  • 色谱分析：HPLC/GC CTC/LEAP PAL 自动进样器样品进样、标准品自动分装；
  • 样品前处理：自动化液体处理系统（如样品稀释、移液）；
• 适配设备：仅兼容 CTC/LEAP PAL 自动进样器专用注射器，不兼容 HAMILTON 标准 Small RN 注射器。

（四）关键规格参数
