Easier Syringe Liquid Filtration System

The unmanned syringe filtration system for viscous solutions allows researchers to perform other tasks in the lab while solutions are filtered. The liquid filtration system is low cost and fits most syringes. Using traditional manual methods, filtration of 5mL of solutions can take up to half an hour. While some research uses no more than 5mL at a time, having the ability to have a stockpile of pre-filtered solution without spending more time physically manning a syringe is beneficial to the laboratory. Other benefits of the system is the small amount of bench space it takes up along with not having to use any electricity, vacuum, or other utilities.

Hands Free Syringe Filter System for Lab Work

Loaded syringes and filter are placed in the “Gopher Squeeze” which incorporates a pressure knob to replace the force applied by hand. This mostly hands-free system gives researchers more time to work on other tasks in the lab while watching the filtration process and turning the knob to increase the spring tension to keep pressure on the syringe. The “Gopher Squeeze” minimizes micro-air bubbles within the solution. It keeps a more even and constant pressure that allows for higher flow rates than manual methods. This technology frees up the user to perform other tasks while maintaining effective filtration.

BENEFITS OF GOPHER SQUEEZE FILTRATION SYSTEM:

  • Allows for syringe filtration without operator
  • Low cost system that fits most syringes
  • Gives researcher the ability to easily stockpile filtered solutions
  • Keeps a more constant pressure on syringe
  • Produces higher flow rates than manual methods
  • Frees up user to perform other tasks
