Filter membrane concentration/density gradient separation fluorescence staining method for two insect detection system---

Function*

• The Quicstar Filter ultra efficient enrichment and filtration system from Kuaishida is designed for laboratory field sampling. The lighter and replaceable filter can be carried to the field for work, making your enrichment process more efficient.

• The Quicstar-1000 fully automatic calcium carbonate precipitation and enrichment system from Kuaishida is designed for laboratory automation of 10L raw water enrichment with turbidity ≥ 20NTU. The process of sample injection, liquid addition, stirring, static extraction, and supernatant extraction is completed automatically without the need for personnel on duty; And multiple hosts can be connected in parallel according to the actual situation, which can achieve 10 channels of sample operation on one control screen.

efficiency

• According to the usage scenario, multiple hosts can be connected in parallel for batch processing of samples, and the number of channels can be increased to 10.

• The sedimentation method automatically completes the pretreatment of 10L raw water and 12-16 hours of static sedimentation, without the need for personnel to be on duty. It can be equipped with a built-in vacuum system to complete the dyeing work and reduce the use of space.

• The relative standard deviation of the test results is ≤ 20%.

• The comprehensive recovery rate of the two insects is greater than 35%.

• The relative standard deviation of the results is ≤ 20%.

Easy to operate

• 10 inch screen guided operation, easy to get started.

• The central control platform can customize workflows.

• Customizable sample volume for real-time reminder/stop.

method

• Compliant with the GB 5750.12-2023 "Testing Methods for Drinking Water Standards", using membrane concentration/density gradient separation fluorescence staining method.

• Compliant with the "Testing Method for Urban Water Quality Standards" CJ/T 141-2018 membrane concentration/density gradient separation fluorescence staining method.

principle

Microporous filter membrane intercepts two insect samples

Quicstar Filter uses a 1um pore size mixed cellulose lipid microporous membrane as a container for intercepting and treating two insects in water,

Mixed cellulose ester microporous membrane (MCE) A100A142C

Pore size of 1um, hydrophilic material design, maintains high throughput for low turbidity treated water samples, can continuously filter 100L, reducing manual operation.

The pressure resistant design of the shell utilizes automated programming technology to more effectively intercept two insect egg sacs and spore sacs in 50L treated water through pressure monitoring and flow rate control. Working principle: Technical requirements for membrane concentration in GB/T 5750.12.

Automatic calcium carbonate precipitation enrichment of two insect samples

According to GB/T 5750.12, Quicstar-1000 is designed with a fully automatic calcium carbonate enrichment unit that does not require personnel to be on duty for raw water samples with turbidity ≥ 20NTU.

Alkaline substances cause the two worm egg sacs and spore sacs in the sample to settle to the bottom of the bucket after 16 hours of standing, and then enrich the two worm samples through centrifugal separation and purification.

process

Membrane enrichment:

stepStep 1

fastShida Quicstar Filter has completed the enrichment of 50L water sample.

Step 2

Fold the mixed cellulose lipid filter membrane and transfer it to a 50mL centrifuge bottle, then dissolve it in acetone.

Precipitation enrichment:

Step 1

Quicstar-1000 automatically completes the precipitation of calcium carbonate in a 10L water sample, retaining 200mL of sediment.

Step 2

Dissolve the precipitate in aminosulfonic acid solution and transfer it to a 500mL centrifuge bottle.
