P1, P2, P3, P4 – Sedi-Rate^®, Plastic sedimentation pipettes according to the Westergren method

General
The plastic pipette itself is the common feature of the P1, P2, P3 and P4 system. It is manufactured in polystyrene and is treated in this manner that the use of the pipette is identical to the use of a glass pipette. Every pipette has an identical graduation, this from 0 – 180 mm. The pipette features a unique fibrous plug located at the zero mark, which expands when in contact with blood. This leads to following major benefits:

• Due to the location of the plug (at zero value), all blood samples are automatically at initial condition.
• The plug is specifically designed to be a self-sealing aerosol barrier. In this way, the plug guarantees that the blood does not pass which increases the hygiene and safety of the test.

This is the most simple design with the features as mentioned above. The blood is aspirated up to the plug, this for example with the help of an aspiration pomp, and the test can be initiated. These pipettes can be used with all conventional (open) tubes.

This design distinguishes itself from the simple P1 version as following:
A unique rubber ring is attached at exactly 6 cm from the bottom of the tube. When the sedimentation pipette is pushed into a blood collection tube of 75 x 13 mm (you can use the conventional as well as the vacuum tubes), a pressure is created which pushes the blood automatically up to the plug at the top of the pipette. This in just one move. (No more need for suction). Due to the unique combination of the ring at the bottom and the plug at the top (which prevents blood from passing), a complete hermetically closed system is created.

Safe, hygienic and time-saving!

Completely closed system!Here the tubes with 0,25 ml citrate, which are necessary for 1 ml blood, are included in the delivery. The tubes come with a pierceable TAPVAL closure. Ideal for a perfect sealing. By pushing the P3 pipette into the tube through the TAPVAL closure, an overpressure is created which makes the blood rise up to the plug. This all in just one move. When the blood reaches the plug, it is immediately situated at zero value.

A complete hermetically closed and safe concept!

Decreasing the risk for serious infections during the handling of blood samples is no longer the only concern. There’s an increasing demand for an efficient and hygienic method that requires a minimum amount of blood and obviously yields comparable results as with the standard method.

The SEDI-RATE^® P4-MICRO SYSTEM is the ideal solution!

This system is almost identical to the P3 sedimentation pipettes. The P4 MICRO is recommended in paediatrics and laboratories with low blood volumes.
The tube (55 x 12 mm) is filled with 0,08 ml citrate 106 M, necessary for 0,32 ml blood.
The pipette is graduated and has an inner diameter of 1,25 mm.

A suitable, handy rack for 10 sedimentation pipettes. The rack is made out of aluminium and therefore easy to clean. Autoclavable.
