Microtainer SST (Serum Separator Tube) Capillary Blood Collection Tubes with a serum separator additive are designed for collecting small blood samples, typically from a fingerstick or heelstick. These tubes contain a clot activator and a gel that separates serum from the cellular components once centrifuged. They are used for:

  1. Chemistry Tests: Analyzing metabolic functions and organ health.
  2. Serology: Detecting antibodies and antigens.
  3. Endocrinology: Measuring hormone levels.

They're particularly useful in settings like pediatrics or when only a small sample volume is needed, ensuring efficient separation of serum for accurate testing.

Microtainer SST Capillary Blood Collection Tubes with Serum Separator Additive and Microgard Closure are engineered for efficient and accurate capillary blood collection. Ideal for small volume serum testing, these tubes ensure reliable results with minimal discomfort, making them perfect for pediatric and geriatric patients.

Details and Features

  • Dimensions: Compact size at 15.3 x 46mm, facilitating easy handling and storage.
  • Volume Capacity: Designed for volumes from 400 µL to 600 µL, suitable for micro-sampling needs.
  • Serum Separator Additive: A gel additive effectively separates serum from cells, ensuring high-quality samples.
  • Microgard Closure: Provides a secure seal, preventing contamination and leakage.
  • Packaging: Available in boxes of 50, ideal for clinics and labs requiring precise, small-volume collections.

Mechanism of Action

The serum separator additive forms a stable barrier between the serum and blood cells during centrifugation, preventing cell contamination and ensuring the purity of the serum. The Microgard Closure further ensures sample integrity by providing a secure and contamination-free seal.

Directions for Use

  1. Preparation: Prepare the site for capillary puncture and gather all necessary equipment.
  2. Collection: Perform the capillary puncture, collecting blood up to the indicated fill line (400-600 µL).
  3. Mixing: Gently invert the tube 5 times to ensure the blood mixes with the serum separator additive.
  4. Centrifugation: Follow lab protocols to centrifuge the tube, enabling serum separation for analysis.

Warnings

  • Proper Fill: Ensure the tube is filled within the specified volume range to maintain accuracy in results.
  • Handling and Safety: Handle with care to avoid contamination and ensure correct sample identification.
  • Storage Conditions: Store in a cool, dry place, maintaining temperature between 4°C and 25°C.
  • Single Use: These tubes are intended for one-time use. Do not reuse or attempt to sterilize.
  • Expiration Check: Use before the expiration date printed on the packaging to ensure effective performance.

Microtainer SST Capillary Blood Collection Tubes with Serum Separator Additive offer a dependable solution for serum testing in micro-sampling, providing reliable results with high ease of use and safety.

FAQs About Vacutainer Tubes
  • What Are Vacutainer Tubes?

    Vacutainer tubes are specialized, sterile blood collection tubes designed for safe, reliable, and contamination-free blood draws and specimen handling. These color-coded, single-use tubes ensure accurate diagnostic testing in hospitals, medical labs, clinics, and phlebotomy centers.

  • How are Vacutainer Tubes Used?

    Blood is drawn from the patient using a needle attached to a special holder. Tube is inserted into the holder; the vacuum draws the correct amount of blood into the tube. Tube is gently inverted (if required) to mix the blood with the additive. Tubes are labeled and sent to the laboratory for analysis.

  • Advantages of Vacutainer Tubes

    Safety: Minimizes exposure to blood. Efficiency: Allows multiple tubes to be drawn in a single venipuncture (“multiple draw” system). Accuracy: Delivers the correct volume for standardized testing.

  • Do Vacutainers Need to Be Sterile?

    Yes! Vacutainer tubes are sterile and individually sealed to prevent contamination and ensure accurate blood test results.

  • What is the Correct Order of Draw for a Vacutainer?

    Order of draw (to prevent cross-contamination): Blood culture bottles (yellow or SPS) Light blue (citrate) Red (serum, glass) Gold/Tiger top (SST, serum separator) Green (heparin) Lavender/Purple (EDTA) Gray (fluoride/oxalate)

  • What Do the Colors on Vacutainer Tubes Mean?

    Each color represents a different additive and test type: Yellow: Blood cultures, sterile Light Blue: Sodium citrate, coagulation studies (PT, aPTT) Red: No additive/Clot activator, chemistry/serology Gold/Tiger (SST): Serum separator (chemistry panels) Green: Heparin, plasma chemistry Lavender/Purple: EDTA, hematology (CBC) Gray: Sodium fluoride/potassium oxalate, glucose testing

  • Can Vacutainers Be Reused?

    No. Vacutainer tubes are single-use only to prevent infection, cross-contamination, and ensure accurate lab results.

  • How to Sterilize a Vacutainer?

    Do not attempt to sterilize or reuse. Always utilize new, sterile vacutainer tubes for each blood draw.

  • Where to Discard Vacutainer Tube?

    Dispose of used and expired vacutainers in a biohazard sharps container, as per OSHA and CDC safety protocols.

  • How Many Times Should an EDTA Tube Be Inverted?

    Gently invert the EDTA (lavender top) tube 8–10 times to mix the blood with the anticoagulant for accurate results.

  • What Are Common Phlebotomy Errors?

    Incorrect order of draw Insufficient mixing of tubes Underfilling or overfilling tubes Using expired tubes Hemolysis from poor technique Mislabeling specimens

  • What Color Lab Tube Do You Draw First?

    The blood culture (yellow/SPS) bottle is always drawn first to avoid contamination, followed by the light blue citrate tube.

  • What is a Grey Top Vacutainer Used For?

    Grey top tubes contain sodium fluoride and potassium oxalate and are used for glucose and lactate testing, as they prevent sugar breakdown in the sample.

  • What Color Should Blood Be When Drawn?

    Blood should appear dark red (venous) or bright red (arterial), based on the draw. Abnormal colors may indicate clinical problems.

  • Does a Vacutainer Expire?

    Yes, each vacutainer has an expiration date for sterility and additive effectiveness—never use expired tubes for specimen collection.

  • What Can Happen if Vacutainers Are Mixed Vigorously?

    Vigorous mixing causes hemolysis (rupture of red blood cells) and sample rejection. Always invert gently as instructed.

  • Are Vacutainers Single Use Only?

    Absolutely. Never reuse; always discard after a single blood draw to maintain patient safety and sample integrity.

  • What Temperature Should a Vacutainer Be Stored At?

    Store vacutainer tubes at room temperature (15°C–25°C / 59°F–77°F) in a dry, cool place away from direct sunlight and moisture.

  • How to Dispose of Expired Vacutainers?

    Expired vacutainers are disposed of in a biohazard sharps or chemical waste container per your lab’s safety policy.

  • How to Memorize Order of Draw Phlebotomy?

    Use the mnemonic: "Boys Love Ravishing Girls Like Dieters Love Greek Yogurt" (Blood culture, Light blue, Red, Gold, Light green, Dark green, Lavender, Gray, Yellow).

  • What Happens if You Underfill an EDTA Tube?

    Underfilling alters the blood-to-anticoagulant ratio, skewing hematology test results (like CBC). Always fill tubes to designated mark.

  • What is SST in Phlebotomy?

    SST (Serum Separator Tube) contains a gel that separates blood serum from cells after centrifugation. Used for chemistry panels, serology, and immunology tests.

  • What Labs Go in What Color Tubes?

    Blood culture (yellow): Microbiology Light blue: Coagulation (PT, aPTT) Red/Gold/Tiger: Chemistry, serology, immunology Green: Plasma chemistry (troponin, ammonia) Lavender/Purple: Hematology (CBC, HbA1c) Gray: Glucose testing
