This fiber optic micro pH sensor is housed inside a 70 mm long syringe needle compatible with the sample holder for our BOBS™ instrument to allow real-time measurements of pH in micro liter samples.
The pH sensitive tip of the optical fiber is protected inside a stainless steel needle, but for measurement purposes the tip can be exposed by pressing a plunger. This design allows for easy penetration through skin, a rubber septum or any other harsh material as well as for secure transportation and insertion.
Implantable pH micro sensors are the miniaturized fiber-optic chemical sensor designed for all research applications where a small tip size of ca 140 µm are necessary. Implantable pH micro-sensors are ideal for costumer-specific set-up. They were applied for implantation in blood circuits and for profiling with a high spatial resolution.
This sensor is the miniaturized fiber optic chemical sensor designed for all research applications were a small tip size of ca 140 µm are necessary. Needle type pH micro sensors are ideal for pH profiling in sediments/biofilms or invasive work with a high spatial resolution and measurement in very small volumes. The pH sensitive tip of an optical fiber is protected inside a stainless steel needle. Such a design is the best for an easy penetration through skin, a rubber septum or any other harsh material as well as secure for transportation. For measurement purposes the sensor must be pushed out from the needle.
