what is SPE vacuum manifold
SPE vacuum manifold is a laboratory instrument used for solid phase extraction (SPE), designed to simultaneously process multiple SPE samples. This device achieves precise fluid control by setting independent spiral valves at each port inside the manifold cover.
- SPE vacuum manifolds come in two models, 12 port and 24 port, and can process up to 12 or 24 SPE samples simultaneously. These manifolds are equipped with patented screw valves that provide better sealing and vacuum control, and can adjust the flow rate of each SPE tube by rotating independent valves.
Features of SPE vacuum manifold
1.Prevent cross-contamination, anti-atomization vacuum tank design, simple and fast operation.
2.The phase-free operation is easy to collect analytes and can handle small-volume samples.
3.The glass vacuum tank is formed by a quartz glass mold with uniform wall thickness and can withstand high negative pressure above -80kPa.
4.The extraction column tray and collection rack are made of special polymer materials, which are beautiful and corrosion-resistant.
5.The top cover of the vacuum device is made of imported polymer material, which is resistant to strong acid and alkali.
The pressure regulating valve is resistant to corrosion, high and low temperature, and durable.

SPE vacuum manifold is a multi tube vacuum solid-phase extraction device that can process multiple SPE tubes simultaneously by connecting a vacuum pump, achieving batch processing of samples. This type of equipment usually has the characteristics of anti cross contamination, easy observation, and easy operation, and is widely used in sample pretreatment in fields such as environment, food, and medicine.
Application
SPE vacuum manifold is widely used in the following fields:
- Environmental monitoring: used for detecting and analyzing pollutants in environmental samples such as water, soil, and air.
- Food safety: Detect harmful substances such as pesticide residues, additives, and heavy metals in food.
- Drug analysis: Separation, purification, and quantitative analysis of drugs and their metabolites.
- Biological sample analysis: detection of hormones, drugs, metabolites, etc. in biological samples such as blood and urine.
