HAMILTON汉密尔顿实验室针 22 gauge, Large Hub Removable Needle (RN), PN: 7779-01

HAMILTON汉密尔顿实验室针 22 gauge, Large Hub Removable Needle (RN), PN: 7779-01产品详情介绍

品牌：HAMILTON（汉密尔顿）
型号：7779-01
产品定位：22 gauge 超细 + 大 Hub 组合的手动进样专用针头，固定规格设计，适配中量注射器与 GC 手动进样、隔垫穿刺场景

（一）产品核心信息

HAMILTON 7779-01 是一款22 gauge 超细规格的大 Hub（Large RN）可移除针头，专为250μL 及以上可移除针头（RN）注射器或SampleLock 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 2（弯曲斜角）防取芯设计，每包含 6 支；采用 304 不锈钢精密制造，支持高压灭菌，主打 “中量注射器适配 + 超细隔垫穿刺 + 手动进样精准性”，是实验室中量手动进样与精细取样的专属耗材。

（二）核心优势

1. 大 Hub+22 gauge 组合，中量超细操作双优
   解决传统 “超细针头适配中量注射器易松动” 的痛点：大 Hub 与 250μL 及以上注射器的连接面积比小 Hub 提升 40%，采用化学抗性压缩密封结构，连接牢固无漏液；搭配 22 gauge（外直径 0.71mm，内直径 0.41mm）超细针体，既满足中量流体（250μL-2mL）的容量需求，又实现微创穿刺、低残留的精细操作。
2. Style 2 弯曲斜角针尖，隔垫穿刺专属优化
   针尖 “弯曲 + 斜角” 双设计经 GC 进样场景专项校准：
   • 防取芯：穿刺进样隔垫时避免橡胶碎屑脱落（取芯率≤1%），杜绝样品污染；
   • 低损伤：弯曲角度匹配隔垫穿刺力学，延长隔垫使用寿命（比直针尖多使用 25 次）；
   • 易操作：斜角锋利度适中，手动穿刺时定位精准且省力，适配 GC 进样口、试剂瓶等各类隔垫。
3. 固定长度精准适配，手动进样更稳定
   50.8mm（2 英寸）固定长度为中量手动进样的黄金尺寸：既保证 GC 进样口内的进样深度（避免样品残留于针管外壁），又适配常规样品瓶高度，配合大 Hub 的宽握柄设计，手动操作时手感统一，进样体积偏差 RSD≤0.2%。
4. 304 不锈钢耐用性，适配高频中量操作
   医用级 304 不锈钢针体耐有机溶剂（如正己烷、丙酮）、耐酸碱，弯曲针尖不易变形；支持121℃高压灭菌，重复使用 8 次以上仍保持针尖锋利度与密封性能，降低中量手动进样的耗材成本。

（三）适用场景

• 实验室中量手动进样场景：
  • 色谱分析：GC（气相色谱）手动进样、HPLC 进样阀中量样品加载；
  • 试剂操作：中量试剂瓶隔垫穿刺取样、密封样品瓶中量加样；
• 临床 / 动物实验场景：
  • 动物中剂量微创注射（如大鼠肌肉、皮下中剂量给药，降低组织损伤）；
  • 中量临床样本（如关节液、脑脊液）微创取样。
• 适配设备：HAMILTON 250μL/500μL/1mL RN 注射器、SampleLock 注射器、主流品牌 GC 手动进样口。
