Biotech Fluidics recently launched SPEedy™, a pocket-sized solid phase extraction (SPE) device designed to complete sample preparation procedures in minutes without the need for an external vacuum. This new handheld mechanism tackles a core technical problem for lab managers by replacing heavy, inconsistent vacuum manifolds with a piston-regulated flow path that minimizes cross-contamination and sample dry-out risks.
Editor's Note: The solid phase extraction market is experiencing a significant shift as pharmaceutical bioanalysis and environmental testing demand more rigorous, high-purity sample preparation. This announcement from Biotech Fluidics reflects a growing industry need for solutions that bypass the mechanical limitations of traditional vacuum setups, offering lab managers a practical way to ensure reproducible flow rates while reducing the physical footprint of sample prep stations.
How does the SPEedy device control solid phase extraction flow rates?
A workflow diagram illustrates how the SPEedy device uses a manual piston mechanism to control solid phase extraction flow rates.
The SPEedy device controls solid phase extraction flow rates through a patented manual piston mechanism that regulates volume during loading, washing, and elution. This mechanical control replaces external vacuums, drastically reducing the risk of sample dry-out.
The upward movement of the piston creates the exact amount of vacuum needed to pull liquid through the sorbent bed, while a one-way check valve prevents air leakage. Conversely, the downward movement creates sufficient positive pressure to displace the exit liquid directly into a collection vial. This design means every sample maintains its solution state, minimizing clogging hazards.
Why is the SPEedy device an effective alternative to traditional vacuum manifolds?
This pocket-sized device serves as an effective alternative to traditional setups by replacing heavy vacuum manifolds and expensive positive pressure instruments with a portable, contamination-free system. By giving each sample its own dedicated flow path, this new mechanism effectively neutralizes the risk of cross-contamination between distinct assays.
Conventional SPE procedures typically require bulky equipment and a constant gas supply, consuming valuable laboratory bench space. The current 10 mL SPEedy device adapts to almost any adsorption chemistry or eluent composition. Biotech Fluidics is developing a fully automated, motorized version of the tool.
- Piston-driven operation: Creates required vacuum and positive pressure mechanically, eliminating the need for gas lines or external pumps.
- Dedicated flow paths: Prevents cross-contamination by keeping each sample isolated within its own channel.
- Drying prevention: Manual flow control ensures the sorbent bed does not accidentally dry out, improving recovery reproducibility.
- Portability: Handheld design frees up critical benchtop space previously occupied by large manifolds.
Solid phase extraction technology comparison versus traditional systems
Comparing the SPEedy device to traditional vacuum manifolds highlights significant operational differences in power requirements, flow control, and physical footprint. This shift in mechanical design directly impacts the reliability and reproducibility of daily solid phase extraction workflows.
While conventional systems rely heavily on external pumps and constant gas supplies, this new manual piston design operates entirely independently.

Streamlining the future of solid phase extraction sample preparation
The introduction of this handheld device marks a practical advancement in solid phase extraction workflows by offering a straightforward mechanical solution to persistent vacuum and contamination issues. By transitioning from bulky, inconsistent manifolds to a controlled piston design, lab managers can achieve more reproducible sample preparation. Ultimately, this innovation allows laboratories to free up valuable benchtop space while maintaining rigorous analytical quality standards.
