Contamiless Sampling Port
Contamiless Sampling Port
This is a solute sampling port for bacteria control, such as hemodiaysis dialysate. Sampling cap seals top and bottom screw, and no bacteria can release to the main stream.
Cap has long elastomer stroke for puncture needle. Bacteria on a cap surface cannot growth to the main stream.
Available needle size : 19 - 24 G
Cap Life : 1 to 5 times of puncture, depends on needle size
Proof Pressure with virgin cap : 1.3 kg/cm2, 130 kPa, 990 torr, 19 psi
Maxmum teｍparature for heat sterilization : 95 C, 203 F
Adjustable tube size : 5.0 mmID, 6.4 mmID
Port material :
for 5.0 mmID - Stainless SUS316L
for 6.4 mmID - Stainless SUS316L, Polycarbonate
Schema of sampling port with cap
This is a cross-sectional view of the port.
The cap is filled with elastomer, so there are no cavities and no liquid retention.
Please be aware that bacteria can easily breed in ports where liquid accumulates inside.
When replacing the cap of this port, applying isodine or other antiseptic solution will prevent the growth of bacteria on the threaded part.
In addition, since the distance the needle penetrates is long, it takes time for bacteria to enter through the penetration mark, and contamination of the flow path can be avoided.
The upper part of the cap has a curved structure, so there is no residue of alcohol, etc.
Ports that use needles are a good way to prevent abnormal analytical values due to bacterial contamination, although there is a risk of accidental puncturing during sampling.
