Capillary Electrophoresis Polymer Storage Using Vacuum-Sealed Bag
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In capillary electrophoresis apparatus, the polymer used as a separation medium deteriorates due to exposure to air, leading to inefficient use as the surface polymer remains unused until the end, causing denaturation and oxidation.
Innovation Solution
A polymer container that seals the polymer from air contact, using a flexible plastic bag or pouch with a vacuum-sealed design and a cap system to prevent oxidation, ensuring the polymer is used efficiently by eliminating air exposure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If the polymer is stored in a polymer bottle with the tube extending to the bottom, then the polymer at the bottom is used first, but the polymer at the surface remains until the end and deteriorates due to air exposure
Solution Approach 1:
The polymer is stored in a polymer bag that is vacuum-sealed to create an inert environment free from air contact. This prevents oxidation and deterioration of the polymer, allowing complete utilization of the polymer without waste while maintaining its effectiveness throughout the entire storage period
Solution Approach 2:
A flexible polymer bag is used instead of a rigid polymer bottle. The bag can be collapsed as polymer is dispensed, ensuring that air cannot enter and contact the polymer surface. This flexible containment structure enables complete polymer utilization while preventing deterioration
2Ease of operation
If the polymer surface is exposed to air in the polymer bottle, then the polymer can be easily accessed, but the polymer deteriorates due to oxidation and denaturation
Solution Approach 1:
The polymer is stored in a vacuum-sealed polymer bag that creates an inert environment, preventing air contact and oxidation. The polymer remains stable and reliable while still being easily accessible through the pump system that draws polymer from the bag
3Productivity
If the polymer is used until the end in the polymer bottle, then complete polymer utilization is achieved, but the remaining polymer is denatured and wasted
Solution Approach 1:
The vacuum-sealed polymer bag creates an inert environment that prevents polymer deterioration throughout the entire usage period. This enables complete polymer utilization without waste, as the polymer remains effective until the very end of the container
Solution Approach 2:
The invention prevents polymer waste by maintaining polymer integrity throughout storage and usage. The pump system is designed to extract polymer efficiently until the bag is completely empty, ensuring no usable polymer is discarded due to deterioration
