-------------------------------------------------------

HamiltonSample injection needle products provide different needle styles according to different application fields. Standard needles are made of stainless steel, and the optimization process is determined based on usage and injection needle capacity. The standard length of a needle is51Millimeter, standard needle tip type is2or3.

Standard needle number：

l26s, used for5μLand10μLThe injection needle.

l22s, used for25μLand250μLThe injection needle.

l22, used for500μLOr above injection needles.

pst2：Standard needles used for chromatographic analysis,10~12°Slant angle, non center point, recommended for diaphragm penetration. (Needle number distribution from)22s~26sThe most ideal needle for diaphragm penetration

pst3：90°Slant angle, mainly used inHPLCOn the injection valve. There is a precise injection volume, recommended for sample pipetting. (such as thin layer chromatography)

pst4：The needle angle is10~12°And animals will leave obvious spikes after injection.

pst5:：A conical needle with a sealed port and side hole can prevent the port from being blocked when the diaphragm is pierced. The distribution of available needle numbers is from10~26sFine calibrated non crystalline vinyl plastic needles with ideal diaphragm piercing effect.

pstAS:：have8°The conical needle is designed to pierce throughGCThe spacer of the automatic sampler. provide26,26s,23,23s,22,22sStandard needles, other models of needles need to be ordered.

These needles are all refined through electronic polishing and electroplating, which is an electrochemical manufacturing process for removing material influences and burrs. This process is used forpst2andpst3The manufacturing of needles aims to minimize damage to biological membranes during puncture. The range of needle tips that can be electroplated for refinement is10~26s.SNNeedles are only standard conical needles.
