Although virtually unbreakable, these sturdy pins precision machined from 5/16 inch stainless steel rod can be easily dropped and lost when not seated in a JMC ESP PLUS Master or Regular Extension.
This extension lets you sample 3 feet deeper than the length of your sampling tube. (6 feet with a 3 foot tube) If you want to sample deeper than that you will need to purchase one or more JMC ESP Plus Regular Extensions in addition to this extension.
This extension lets you sample three feet deeper provided you have a ESP Plus Sampling Tube and a JMC ESP Plus Master Extension. Regular extensions connect to each other for additional sampling depth capability.
Use our solid tip instead of a cutting tip to plunge to desired depth without filling the sampling tube. Useful for creating small diameter monitoring wells or limiting sample debris.
