7770-02 HAMILTON 汉密尔顿实验室针 22 gauge 小 Hub 可移除针头（PN:7770-02）产品详情介绍

品牌：HAMILTON（汉密尔顿）
型号：7770-02
产品定位：22 gauge 超细钝头专用针头，固定规格设计，适配 HPLC 进样阀与低损伤取样场景

（一）产品核心信息

HAMILTON 7770-02 是一款22 gauge 超细规格的小 Hub（Small RN）可移除针头，专为100μL 及以下可移除针头（RN）注射器设计，无需额外配件即可直接适配。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 6 支；采用 304 不锈钢精密制造，支持高压灭菌，主打 “低损伤穿刺 + 防堵塞 + 进样阀适配”，是实验室 HPLC 操作、细胞取样等精细场景的专用耗材。

（二）核心优势

1. Style 3 钝头设计，双重防护更安全
   针尖圆润无锋利边缘，针对低损伤需求专项优化：
   • 防组织损伤：用于小动物注射或组织取样时，可减少皮肤、黏膜及细胞的机械损伤，降低实验对象应激反应；
   • 防堵塞防污染：穿刺密封垫或取样时，避免吸入微小颗粒导致针头堵塞，同时减少密封垫碎屑脱落污染样品（比尖头针头污染率降低 95%）。
2. 固定长度精准适配，操作更稳定
   50.8mm（2 英寸）固定长度为 HPLC 进样阀、常规样品瓶的黄金适配尺寸：既保证进样阀内的精准液体推送，又避免长度过长导致的操作冗余或过短导致的进样不充分，手动操作时手感统一，进样体积偏差 RSD≤0.2%。
3. 小 Hub 低死体积，超细规格省样品
   • 小 Hub 结构可精确对准注射器 “零刻度线”，死体积≤0.05μL，配合 22 gauge（外直径 0.71mm，内直径 0.41mm）超细针体，显著减少核酸、蛋白等珍贵微量样品的残留浪费；
   • Hub 与注射器连接间隙≤0.01mm，密封性能优异，无漏液风险，适配超净台内无菌操作。
4. 304 不锈钢耐用性，适配高频使用
   医用级 304 不锈钢针体耐酸碱、耐有机溶剂（如甲醇、乙腈），虽为 22 gauge 超细规格但机械强度优异，不易弯折；支持121℃高压灭菌，重复使用 5 次以上仍保持钝头圆润度与密封性能，降低耗材更换频率。

（三）适用场景

• 实验室精密操作场景：
  • 色谱分析：HPLC 进样阀样品加载、手动进样器液体转移；
  • 细胞生物学：细胞培养上清收集、原代细胞微量给药（避免细胞破裂）；
  • 试剂操作：密封样品瓶微量取样、无菌试剂分装；
• 临床 / 动物实验场景：
  • 小动物微创注射（如小鼠皮下、腹腔低损伤给药）；
  • 微量临床样本（如泪液、口腔黏膜液）无创取样。
• 适配设备：HAMILTON 100μL 及以下可移除针头注射器、主流品牌 HPLC 进样阀（如安捷伦 1260 系列）。
