Black PTFE Carbon Plunger Seals HPLC replacement seal parts

Description

We can custom all kinds of seals as per your requirements. Name: Black PTFE Carbon Plunger Seals HPLC replacement seal parts.

Teflon Carbon Plunger Seals are high-quality replacement seal parts for HPLC. These seals are made of Teflon (PTFE) and carbon, which provide excellent chemical resistance and wear resistance. These plunger seals can fit a wide range of HPLC pump heads and can be easy to install for leak-tight sealing. Black PTFE Carbon Plunger Seals are suitable for use in a variety of analytical applications, including chromatography, medical analysis, and environmental testing. And, it is also okay for other types of pumps and valves where precise sealing is required.

Details about HPLC replacement Plunger seal parts.

First, why need to replace the Shimadzu high pressure infusion pump plunger rod seal ?

A: Black PTFE Carbon Plunger Seals are vulnerable parts of the high-pressure liquid chromatography infusion pump.
High-pressure pump plunger rod requires constant reciprocating motion, after which the instrument used for a long plunger rod seal is worn. Once the plunger rod seal wear serious, it will cause closed lax in pump operation, the mobile phase liquid will leak out of the fray, leading to instability and even pressure pump does not work.
Mobile phase salt does not pay attention to timely clean plunger rod will increase the wear rate of the plunger rod. Because beside the plunger rod after crystallization,  wear of the plunger rod will increase for the fine salt crystals.

Second, how to determine to replace the Shimadzu LC-20AT high pressure infusion pump seals (228-35145)?
A: Follow these three steps to determine
1, high-pressure pump, high pressure pump pressure volatility.
2, open the vent valve (PURGE) after the discharge pressure of the bubble is still volatile.
3, the bottom of the pump head with a liquid leak out (can be wiped with a filter paper at the bottom of the pump head).

Third, how to replace Shimadzu  high pressure infusion pump seals ?
1. Remove the respective connecting pipe pump, remove the pump head with a hex wrench.
2, Shimadzu pump seals special tool to remove the old Shimadzu high pressure infusion pump seals , and then seal the other end of the new seal into the top of the pump head, the pinch .
3, the pump head and putting it back again, re-connect the respective connecting pipe.
