Provacuter Gel Clot Activator Tube
Provacuter Gel Clot Activator Tube
The clot activator sprayed on the inner wall of tube can accelerate clotting. Particles in the white or brownish film on the interior surface activate clotting when tubes are mixed 5-8 times by inversion. The tube contains a gel barrier polymer at the tube bottom. The density of this material causes it to move upward during centrifugation to the serum-clot interface, where it forms a barrier separating serum from the clot. Serum may be aspirated directly from the collection tube, eliminating the need to transfer to another container.

Storage
Storage tubes at 4-25℃ (39-77°F), unless there is other notice on the package or label. All liquid preservatives and anticoagulants are clear and colourless. Do not use if they are discoloured or contain precipitates. Clot activator may be white or brownish; fluoride and fluoride/oxalate may be pale pink. Do not use if colour has changed. EDTA or clot activator spray coated additives may have a brownish appearance; this does not affect the performance of the EDTA additive or clot activator. Do not use tubes after their expiration date. Tubes expire on the last day of the month and year indicated.
Shipping Information
No special requirements – a normal, dry shipping container is adequate.
Sterilisation
By irradiation as per European Union directives: UNI EN 552, UNI EN 556-1 ISO, 11137, UNI EN ISO 11737-2
Clotting Instructions
Allow blood to clot thoroughly before centrifugation. The recommended minimum clotting time for PROVACUTER Gel & Clot Activator Tube is 30 minutes. Tubes with clot activator or/and gel should be inverted 5-8 times.
Centrifugation
Do not centrifuge glass tubes at forces above 2200 RCF in a horizontal head (swinging bucket) centrifuge as breakage may occur. Glass tubes may break if centrifuged above 1300 RCF in fixed angle centrifuge heads. Always use appropriate carriers or inserts. Use of tubes with cracks or chips or excessive centrifugation speed may cause tube breakage, with release of sample, droplets, and an aerosol into the centrifuge bowl. Release of these potentially hazardous materials can be avoided by using specially designed sealed containers in which tubes are held during centrifugation. Centrifuge carriers and inserts should be of the size specific to the tubes used. Use of carriers too large or too small for the tube may result in breakage.
The following table gives recommended centrifuge RCF and time using a horizontal head (swinging bucket) centrifuge:
| Product | RCF（g） | Time (minutes) |
| Sodium Citrate (9NC) Tubes (Platelet-rich plasma) | 150 | 5 |
| Sodium Citrate (9NC) Tubes (Platelet-poor plasma) | 1500-2000 | 10 |
| Sodium Citrate (9NC) Tubes (Lack of platelet plasma) | 2500-3000 | 20 |
