Vacutest Kima K2EDTA haematology tubes, 1 ml, 13 × 75 mm

Purple haematology tubes with a plastic tube, a pre-measured vacuum and a sterile interior.

All tubes have a leak-proof cap to protect against direct or aerosol contamination. The stopper diaphragm is made of soft rubber to prevent puncture incidents.

• Packaging: 100 pcs/box - 1000 pcs/carton.
• Vol.: 1 ml
• Dimensions: 13x75 mm
• Type: purple cap

KIMA Vacutest tubes are made of polyethylene terephthalate (PET), a transparent material that allows visual inspection of blood and other biological fluids. The tubes resist mechanical impact, centrifugation and cracking if accidentally dropped during use.

Standard tube dimensions:

• 13x75 mm
• 13x100 mm
• 16x100 mm

To improve the quality of coagulation test results, Vacutest KIMA produces tubes with thicker walls (special Vacutest IN technology). Vacutest IN tubes allow blood to reach a higher level in the tube than standard tubes of a similar volume, further preventing possible platelet activation.

A special transparent polypropylene label covering the full height of the tube prevents evaporation of the sodium citrate buffer solution, maintaining a blood:anticoagulant ratio of 9:1 throughout a long shelf life of up to 12 months.

This patented combination of Vacutest IN technology and a transparent polypropylene label guarantees the reliability of laboratory tests.

Cap / Stopper

The tube cap consists of a pierceable butyl rubber stopper and an outer plastic cap. The stopper has a recess at the puncture site to protect the operator from possible contact with blood.

The outer cap is made from polyethylene and protects against aerosols and splashes, prevents operator contact with the rubber stopper and allows easy recapping.

The special shape of the outer cap allows the same holder to be used for tubes with cap diameters of 13 mm and 16 mm.

Stopper colour coding complies with ISO 6710

Blood collection procedure

When multiple blood samples need to be collected from a single patient, the specific blood collection procedure recommended by CLSI (Clinical and Laboratory Standards Institute) must be strictly followed to eliminate any possibility of cross-contamination of samples with tube contents.

Caution!

Because red-cap tubes contain a clot activator (silicon dioxide), the blood collection procedure begins with a more sensitive sample for coagulation studies in blue-cap tubes. When using butterfly blood collection needles, some blood remains in the catheter, which can alter the blood/anticoagulant ratio, especially when blood is collected into a sodium citrate tube. To obtain reliable coagulation test results, the first tube must be discarded. Tests are performed using a second tube. The discarded tube can be either a tube without additives (white cap)* or a coagulation tube.

Filling the tubes

The measured vacuum ensures that the tube fills with a precisely defined blood volume. For additional blood volume control, each tube has a level mark on its label.

In accordance with international ISO, EN and CLSI recommendations, a filling tolerance of +/- 10% relative to the fill-level mark on the label is permitted.

Sample homogenisation / mixing

After blood collection, the tube contents must be mixed thoroughly to prevent clot formation and partial blood coagulation.

Caution! All tubes must be mixed, including those containing a clot activator.

Sample storage and transport

The storage time for samples collected from patients depends on the type of investigation/test and the stability of the specific analytes.

Centrifugation

Samples requiring preliminary centrifugation must be placed in the centrifuge no later than 2 hours after collection.
