Általános leírás

For continuous "hands off" direct transfer of multiple liquid samples

A Visiprep large volume sampler enables you to transfer low viscosity samples directly from any sample container to conventional solid phase extraction tubes on a Visiprep SPE vacuum manifold.

Two samplers are available. One sampler has three tube adapters compatible with 12mL, 20mL, or 60mL polypropylene SPE tubes. Simultaneous extraction of 12 samples on a 12-port Visiprep manifold requires four of these samplers. The other sampler has four tube adapters for 3mL or 6mL SPE tubes. To simultaneously extract 12 samples, three samplers are required.

The samplers consist of 1/8-inch PTFE tubing with a screw fitting at one end and a stainless steel weight at the other end. To use the sampler, feed the weighted end into a sample container until it touches the bottom. Insert the tube adapters into the conditioned SPE tubes on your Visiprep manifold. Turn on the vacuum to the Visiprep manifold and open the manifold flow control valves, and the samples will be delivered to the SPE tubes. The flow rate of sample through each tube can be independently controlled by using the flow control valves. Both the screw fittings and the PTFE tubing on the samplers are colorcoded for easy sample identification.

Also fits Preppy SPE Vacuum Manifold.

Note: The Visiprep Large Volume Sampler can only be used with polypropylene SPE tubes. You must equip alternate manifold valves with long stem flow control knobs to accommodate 12 mL, 20 mL, or 60 mL SPE tubes.

Alkalmazás

Visiprep large Volume Sampler was used to extract and determine estrone in water using solid-phase extraction-enzyme-linked immunosorbent assay (SPE-ELISA). It was also used in extraction of polar pesticides from rainwater samples, during extract analysis by LC-MS-MS coupled with electrospray ionization.
