Cleaning validation swab

Cleaning validation swab is for specimen collection for TOC or HPLC analysis.

Huachenyangs TOC Cleaning Validation Swabs were designed to simplify sampling as part of a cleaning validation protocol. The swabs are further cleaned using a proprietary process to make them excellent for use in Total Organic Carbon (TOC) analysis.

Double layered, double knit polyester head entraps contaminants in knit structure during sampling. This allows maximum contaminant collection and release into the diluent to provide for excellent recovery rates

Notched, break-away handle allows the head to be placed into the vial with minimal handling and contamination.

100% polypropylene handle ensures no additional contaminants are introduced and provides excellent chemical resistance.

sterile flocked swab

Sterile flocked swab is ideal for collecting large amount of cells and rapid elution of the specimens instantly release the cells into the transport medium. It is well recognized and adopted by the diagnostic test kit manufacturers who produce reagents in molecular genetics, forensics, clinical laboratories sectors. Flocked swab with ergonomic and anatomic design help improve patient comfort and efficiency in specimen collection. The swab is strictly sterilized and certified free of DNase,RNase and Human DNA and PCR inhibitors.

Saliva dna collection kit

Saliva collection kits are designed to maintain the integrity of DNA in saliva as they contain reagents to preserve the high molecular weight DNA by inhibiting degradation and preventing bacterial contamination.
Multiple studies confirm DNA extracted from saliva samples result in DNA of the highest integrity, performing equivalently to blood for applications such as PCR, SNP, genotyping, microarrays and next-generation sequencing.  Saliva dna collection kit

buccal swab kit

Buccal swab kit consist of flocking swab and buffer, it is for genetic testing such as carrier screening , nutrigenomics , hereditary cancer testing etc. This kit is just for dna sample collection , send the dna sample to lab for testing after collection. The flocked swab is DNA-free and it can get more DNA yield comparing with cotton swab, foam swab, rayon swab and polyester swab. The buffer allow the dna sample stable for up to 30 days at room temperature.

saliva sample collection kit

Saliva sample collection kit is designed to maintain the integrity of DNA in saliva as they contain reagents to preserve the high molecular weight DNA by inhibiting degradation and preventing bacterial contamination. The majority of DNA obtained with saliva kit is > 23kb in fragment size and the amount of bacteria has minimal practical significance as the vast majority is of human origin (average only 11.8% bacteria).
