SP76 Liquid Bottle Sampler

Liquid Sampler NeSSI SP76 modular substrate


Liquid sampling solution for SP76 (NeSSI) Modular Substrates. The Mechatest SP76 (NeSSI) Liquid Sampler is designed to take liquid samples, manual or automatic, directly onto the Modular Substrate NeSSi - ANSI/ISA 76.00.02 base compliant substrate or platform.


NeSSI the New Sampling Sensor Initiatives is the state-of-the-art and next-generation modular liquid sampling system designs for process analytical applications. The miniaturization result in maintaining productivity and quality while achieving drastic reductions in resource and waste generation.


Liquid sampling - SP76 Liquid Sampling Solution - NeSSI liquid bottle sampler Mechatest MBS

  • Sample volumes 50, 100, 250, 500 and 1000 ml (other on request)
  • Max. Process Pressure 8 barg (116 psig)
  • Max. Vapor Pressure 0.7 barg (10 psig)
  • Safe (sampling) Process Temperature 60°C (140°F)
  • Wetted Materials 316SS, Monel, Hastelloy C-276 (other exotic materials on request)
  • Replaceable Needle assemblies for Process and Vent needle, independent to choose in smaller or larger sizes
  • Replaceable seats for the needles PTFE, (Viton or Kalrez) and in a width range of other materials available
  • Replaceable bottle holder makes the sampler very flexible, possibility to change later from bottle volume
  • Bottle holders for GL32 and GL45 thread bottles with screw cap and septum
  • Bottle adapters also for Dopak bottles

The Mechatest NeSSI sampler features a body with three port configuration. We designed two versions; Version 1 provide sample inlet, bypass and vent connection and version 2 is more regular for straight line flow thru for sample inlet/outlet and a vent connection in the middle. On the bottom you place the Mechatest modular “needle sampler”. On the top you can place any valve control device, both connections also based on the ANSI/ISA 76.00.02 – 38.2 mm small footprint.

NeSSI (New Sampling/Sensor Initiative) is a global initiative intended to simplify the assembly and reduce the overall costs connected with the design, engineering, installing, and servicing of process analytical systems.


Sponsored by the Center for Process Analytical Technology (CPAC) at the University of Washington. NeSSi promotes the acceptance and implementation of modular, miniature sample system technology and components using the mechanical design based on the ANSI/ISA SP76.00.02-2002 standard.


Mechatest offers liquid samplers housings conform to SP76 standards. All our housings are designed to have a minimal internal volume to increase the response time and minimize lag time.
