Solid-Phase Extraction Device 19 Holes

Solid-Phase Extraction Device 19 Holes Introduction

Patent#ZL2015205975510

Solid-Phase Extraction (SPE) is a sample preparation process by which compounds that are dissolved or suspended in a liquid mixture are separated from other compounds in the mixture according to their physical and chemical properties. Analytical laboratories use solid phase extraction to concentrate and purify samples for analysis. Solid phase extraction can be used to isolate analytes of interest from a wide variety of matrices, including urine, blood, water, beverages, soil, and animal tissue. There includes use of adsorbent to attach target compounds in liquid sample adsorption, so separate from matrix interference of the compound sample, then elute, achieve the target of separation and enrichment of target sample. Solid phase extraction includes activation, loading, washing and eluting four procedures, choose suitable adsorbents in the process of washing and elution of compounds, adsorbed first target compounds and wash off other interference, but also can make the target compound to leaching down to be collected, the interference of retention (adsorption) in adsorption agent, the two separated.

Solid phase extraction device composed of three parts: solid phase extraction chamber, suction flask and vacuum pump. existing device is arranged from left to right in the three part. Due to the use of volatile organic solvents, the device must operate in a ventilation cabinet which is often only enough to put one. the ventilation cabinet's space is very limited, so SupertechTM SPE workstation, through the plastic base, the vacuum pump is a cuboid by rear solid phase extraction apparatus is fixed in the rectangular slot, suction flask by glue fixed in the vacuum pump above, so that the three parts with very compact, to save space. The suction flask placed on top of vacuum pump, which increase the weight so as to use gravity to eliminate waste liquid automatically. Solid phase extraction system from Supertech is upgraded patent products. The overall compact design wins applause from many labs.

Product feature:

1 automatic waste collection and discharge design: 180mm high from desktop suction flask, increased drop-height.

2 vacuum pump waterproof design: with protection device proof from water.

3 cross design: cross design of all products, the rear elevated 10mm, prevent from confusion.

4 durable design: channel 10mm high from panel, easier reached out to rotate of quark valve, and firm combined (which is currently the most solid product), will not easily scattered, shaking; stainless steel channel consumption is nearly zero.

5 unobstructed design: channel of large aperture (2.5mm) made of stainless steel, liquid flow unobstructed (do not need to draw a vacuum in most cases), under normal circumstances, do not even need a vacuum pump.

6 excellent material: the main part of the glass cylinder for the world first classic glass, the cylinder inside is square, used of special solid glass mold forming, the wall thickness is uniform so that can withstand more than -0.085Mpa of the high negative pressure.

7 waste disposal: by the host glass cylinder directly, there is a valve at the bottom of cylinder used for discharge, liquid discharging valve does not require the use of liquid collection cylinder, or by the suction flask and make the collection of waste liquid,

8 integrated design: solid phase extraction chamber, vacuum pump and suction flask consolidated together, put a reasonable standard, greatly save space of processing ventilation cabinet.

Technical parameter:

1 Size: cylinder 300*100*188mm or 300*100*228mm( (L * W * H);

2 hole number: 19;

3 hole spacing: 27mm;

4 hole height and arrangement: upper and lower cross (front row height out of the panel 10mm, rear panel 20mm), front and back row cross not parallel;

5 waste disposal: at the bottom of the cylinder can be used to collect waste liquid, or during the vacuum, waste can be automatically collected by suction flask, waste liquid discharged from the valve;

6 channels: 2.5mm stainless steel, smooth flow.

7 vacuum pump: 40 L/min, no oil, automatic over heat protection, low noise <48 db.

8 suction flask: 1000 mL, vacuum pump, waste liquid entrance and waste liquid exit, a valve at pumping port, open the valve by press it vertically.

Accessories list:

1 glass cylinder: 1, including vacuum gauge, vacuum control valve.

2 panel: 1, including 19 channels, 19 quark regulating valve.

3 test tube rack: 1, aperture 18mm (suitable for 15mL test tube).

4 suction flask: 1, including water proof protection device, waste liquid valve, silicone tube 3 pcs.

5 vacuum pump: 1 set, including the power wire 1pcs.

6 fixed base: 1pcs.

Instructions:

1 protective film against corrosion: the panel has a transparent plastic material, on the upper surface covering plastic protective film, this is to prevent surface scratches or chemical corrosion, should not be torn off.

2 vacuum control valve: rotary vacuum control valve to adjust with holes, the outer hole aligned with the inner hole is vacuum unloading. Cross to close before run vacuum.

3 SPE column: flow control can be adjusted by the quark valve, vacuum pump control valve,  SPE vacuum control valve.

4 closing all valves before vacuum process: before vacuum process, close all non-inserted cartridge valve, closes the waste quark valve at suction flask, vacuum pumping can not afford otherwise.

5 waste disposal: by the suction flask collection of waste liquid, the liquid discharge valve, suction flask (1L) just above the joint is connected to the vacuum pump; waste comes from glass cylinder bottom out, by the middle of the suction flask into glass nozzle. In the absence of suction flask or waste cylinder case, do not use direct vacuum pump vacuum, or short circuit burned out vacuum pump due to water. Open the suction flask bottom valve, can discharge the waste liquid, at the end, the other end can be slightly raised and tilted discharge.

6 timely waste water: Although the vacuum pump with water proof device, the amount of waste suction bottle should be controlled in 0.8L below, should be timely exhaust.

7 must be cleaning system: in order to keep the tank clean, at the end of each experiment, the 100-300mL must be added to tap water in a glass bowl, open the vacuum pump, to pump all suction bottle, cleaning liquid from the discharge valve.

8 FAQ questions: if the vacuum pumping can be applied, should check whether the closed waste water valve, vacuum control valve and channel quarks not inserted SPE column on the suction flask.

Attention:

1 before use, should carefully read the instruction manual.

2 please be sure to place the instrument on a stable and firm level.

3 During installation, it should be effective grounding.

4 non professionals, non professionals, do not open the chamber.

Instrument maintenance:

1 please keep the environment clean, dust, high temperature and high humidity environment will affect the service life of the instrument.

2 before cleaning the instrument, pull off the power plug from the socket. Please clean the instrument using ethanol soaked cloth. When cleaning, do not use liquid detergent spray cleaning agent, can not use a hard brush to clean the instrument. Instruments either, cool, dry environment helps to  extend the life of instrument.

3 please put the instrument in the level of the laboratory table or the use under ventilation in the cabinet, please keep the instrument from heat source.
