Dip Probes with Embedded Thermistor

Brand: Fluorometrics Instruments

Model: FMI-DPT-AP

Our high-performance Zero-drift oxygen sensor stainless steel probes with an embedded thermistor are designed for monitoring of oxygen in gases and dissolved oxygen in liquids (water, blood,...). This fiber optic probe is 7"(17.78 cm) long and it has 1000/2000 micron polymer fiber. It is biocompatible and can be used in biological environment, life science,...

Factory calibration is included.

Available with three different ODs:

5/32" (0.156", 3.97 mm) OD

1/4" (0.250", 6.35 mm) OD

12/32" (0.375",9.53 mm) OD

Our dip probes are provided with different overcoating:

1- With no overcoat with a response time (t90) of about 3 Seconds.

2- With a white acrylic overcoating for reflected signal enhancement with a response time (t90) about 1 min.

3- With a black acrylic overcoating to protect the sensor from UV, ambient light, environmental effects, and biofouling, with a response time of about 2 min.

Protective Overcoat

Patches

Brand: Fluorometrics Instruments

Model: FMI-P-AP

Our high-performance zero-drift acrylic oxygen sensor patches (AP series) are designed for non-invasive monitoring of oxygen in gases and dissolved oxygen in non-organic and biological liquids (water, blood, … ).

FMI's patches are installed inside transparent containers on a small portion of them prior to filling. Measurements are achieved by using our reflection probe attached to the DOPO2 or by using DOPO2 directly.

We provide oxygen patches in a variety of sizes (OD) and on different materials including polymer and glass substrates.

Our patches are provided with different overcoating:

1- With no overcoating with response time (t90) of about 1 Sec

2- With a white acrylic overcoating for reflected signal enhancement with response time (t90) about 1 min.

3- With black acrylic overcoating to protect the sensor from UV, ambient light, environmental effects, and biofouling, with a response time of about 1 min.

They are available in various outer diameters: 0.25" (6.35 mm), 0.5"(12.7 mm), 20 mm, 3" and custom diameters are available per customer request.

And they are available in three different thicknesses: 0.003" (0.076 mm) thick flexible patch, 0.03" (0.76 mm) and 0.06" (1.52 mm) thick patch

Applications:

Oxygen measurement in single-use bioreactor bags
Food and beverage industry: Oxygen permeation in PET bottles
Bioprocesses: real-time, non-invasive monitoring of oxygen and dissolved oxygen in bioreactors

These patches are pre-calibrated with a known calibration coefficient and slope (using DOPO2 EOM). Pack of 5

About

Fluorometrics Instruments (FMI) is based in Dunedin, Florida. FMI joined AlpHa Measurement Solutions, LLC in July of 2022.

The company was formed by founder Dr. Mahmoud Shahriari in 2012. As a materials scientist, Mahmoud started the research on fiber optic chemical sensors at Rutgers University as a research professor in 1986. He is one of the world’s pioneers in developing optical chemical sensors based on sol-gel technology.

In 1999, he joined the sensor department of Ocean Optics in Florida as the director of R&D. There, he continued his work on optical chemical sensors with Mike Morris, then President of Ocean Optics. During his tenure at Ocean Optics, he successfully developed a number of optical chemical sensor products (oxygen and pH), based on sol-gel technology and introduced them to the market. Mahmoud left Ocean Optics in 2012 to form FMI.

Dr. Shahriari has been developing of a variety of fiber optic chemical sensors since the inception of FMI. Since the company’s inception, his work has been focused on developing and manufacturing a host of optical chemical sensors for life science and industrial applications.

Some of these sensors include zero drift oxygen sensor (AP series), semi-disposable fiber optic O2 sensors, hydrocarbon compatible oxygen sensor (HCR series), fiber optic pH sensors, and fiber optic temperature sensor. FMI’s goal is to provide a wide range of disposable and innovative sensors at a more affordable price-point than competing companies.
