Bullet Points:

• Medical-Grade, Untreated Filter Paper: Made from pure cotton linter, equivalent to Whatman 903®. Contains absolutely no chemical additives or PCR inhibitors — ensuring your DNA, proteins, and biomarkers stay intact for over a decade at room temperature.
• Mess-Free, Triple-Layer Protection: Forget about smudged or contaminated samples. The unique tri-fold hardboard cover folds over and locks the collection area into a recessed chamber. The blood spots are suspended safely inside, preventing any direct contact during shipping.
• Built for Full Traceability: Each card comes pre-printed with a detailed information grid (Donor ID, Collection Date, Site, etc.) plus a barcode area. Scan, record, and maintain perfect chain-of-custody from fingertip to lab.
• Effortless Self-Collection: Just a simple finger or heel prick is all it takes. Fill the pre-printed circles, let the card dry for 1-2 hours, fold it shut, and mail it in the included desiccant pouch. No cold chain required.

Product Description

The Cell-Free DNA Preservation Tube is a direct-draw blood collection tube specifically designed to stabilize cell-free DNA (cfDNA) in whole blood at room temperature. Its proprietary, formaldehyde-free additive immediately prevents cell lysis and nuclease activity, effectively inhibiting the release of contaminating genomic DNA (gDNA) from nucleated blood cells. This ensures that the original cfDNA profile – both in concentration and integrity – is preserved from venipuncture all the way to downstream analysis.

By removing the need for immediate plasma separation and cold-chain transport, the tube simplifies complex pre-analytical workflows in liquid biopsy, non-invasive prenatal testing (NIPT), oncology research, and transplant monitoring. Whether samples are processed within hours or after days at ambient temperature, you obtain high-quality cfDNA that faithfully represents the in vivo circulating nucleic acid population.

Key Features & Benefits

Huachenyang 903 DNA Color Sample Collection Card adopts a unique color technology, the colorless samples such as saliva and body fluid can turn the card from pink to colorless, indicating the area where the sample is located, and have the functions of protein denaturation, cell membrane rupture, DNA adsorption, and inhibiting bacterial growth. The sample can be safely stored for a long time.

Applications

Use for the collection of colorless samples such as body fluids, urine, and spinal fluid, as well as DNA extraction from crime scenes, and collection of plant and animal DNA samples in the field.

Features

• Unique technics: a unique process to indicate a colorless sample collection area.

• Easy to use: only need to spot and dry sample, one hour is enough to purify the DNA.

• Good stability: blood sample could be preserved for over 10 years.

• Functional Test: PCR results of preserved blood sample are the same as fresh blood sample.

• Safe and reliable: lyse the cells and prevent the growth of bacteria and fungi.

• Efficient uses: the DNA bound with the blood collection card can be amplified multiple times.

Product Introduction

903 Proteinsaver card is a sample collection card with five half-inch sample spots.

The Proteinsaver card has a wraparound cover with spaces for name and date of collection. Ready-to-use format saves costs during protein collection, transfport and archiving. The card fits into our Whatman foil barrier resealable bags for storage. It is imprinted with the universal biohazard symbol in accordance with USP regulations.

Room temperature preservation: Contains unique anticoagulation and preservation reagents, which can be stably
transported and stored for 7 days or more at room temperature.
Stable storage: It can stabilize nucleated cells and prevent the release of cell genomic DNA from contaminating target free
DNA; inhibit nuclease degradation of free DNA to ensure sample quality.
Personalized design: Double-coded label design, easy to identify, reduce sample processing errors; clear blood sampling
volume identification, easy to observe; there are various material and size for choice, suitable for different scenarios.
Wide range of applications: Used for NIPT, tumor liquid biopsy, blood pathogenic microorganism detection, genetic disease
detection; third-party medical laboratory, hospital laboratory and obstetrics, etc.

Product Performance

Excellent Protection of Blood Cellular DNA From Releasing

The Viral Transport Medium provides a pH-balanced environment and contains antibiotics to inhibit bacterial or fungal contamination. Microbeads inside the vial ensure more rapid sample dispersion and elution.

Hanks buffer creates a neutral environment, which helps increase the survival time and infection stability of the virus.

Product Description

Features of Flocked Swabs

1. Flocked Swabs-collect and release more secretions and cellular material than traditional swab
2. Sample elutes instantaneously into medium
3. Less QNS rejection with DFA+
4. Ergonomic, anatomic and quantitative
5. Comparable results with nasal washes and aspirates+

Cost-effective and multiple test

1. *Culture-all viruses, chlamydia, mycoplasma and ureaplasma
2. Enzyme Immuno Assays (EIA)
3. PCR
4. Nucleic acid amplification assays including chlamydia trachoma tis and neisseria gonorrhoeae (Ct/Ng)

NOTE:

It allows specimens to be stored at room temperature for 30 days without any change.
