Optical Detectors are used for the detection of optical radiation that is usually accomplished by converting the optical energy into an electrical signal. It include photon detectors, in which one photon of light energy releases one electron that is detected in the electronic circuitry and thermal detectors, in which the optical energy is converted into heat, which then generates an electrical signal.

Orbit variable speed vortexers are suitable for cold room or incubator use. It features variable speed across a broad range, making them useful for a variety of applications. Both time of operation and shaker speed are set and displayed digitally, with their values on the large 3 digits LED. Parameters are selected with an easy turn knob. These vortexers accept all sizes of standard micro plates, including deep well plates. Retaining springs on the contoured steel platform hold samples in place.

Orbital and Reciprocating Water Baths is designed for a wide range of temperature-controlled shaking protocols. It features a high quality, robust design with a unique magnetically coupled shaking mechanism for maximum reliability, consistency and quiet operation. It includes PID controller for easy temperature selection, rapid heat up & excellent stability + 0.1°C, adjustable speed control from 20-200 RPM and convenient drain port with quick disconnect allows for easy cleaning of the bath.

Orbital Incubator Shakers incorporate brushless AC motors for prolong maintenance-free operation with AC drive.

An Otoscope is a medical apparatus, which is used to look into the ears. Health care providers use otoscopes to screen for illness during regular check-ups and also to investigate when a symptom involves the ears. With an otoscope, it is possible to visualize the outer ear and middle ear. Otoscope consists of a handle and a head. The head contains an electric light source and a low power magnifying lens. The front end of the otoscope has an attachment for disposable plastic ear speculums. The examiner first straightens the ear canal by pulling on the pinna and then inserts the ear speculum side of the otoscope into the external ear. The examiner can then look through a lens on the rear of the instrument and see inside the ear canal.

Ovarian Cancer Antigen is an antigenic determinant on a glycoprotein recognized by a monoclonal antibody. It is useful in early detection of relapse of ovarian cancer. Cancer Antigen is useful marker in patient monitoring for ovarian malignancy. It responds to treatment in women receiving chemotherapy for ovarian cancer.

Ovulation Predictor Kit is an optical device, which allows a woman to predict the ovulation phase of her cycle in order to know the days of the month during which she is most likely to conceive. It consists of a small cylindrical container about the size of a lipstick tube and a focalizable eyepiece. An ovulation predictor kit tests female urine for the hormone that signals when ovulation is imminent. It detects the increase in lutenizing hormone (LH) in the urine, which usually occurs 24 to 36 hours before ovulation. The ovulation predictor kit is designed to detect luteinizing hormone or LH.

Ovulation-Prediction Testing Kits includes urinary hormone tests, basal thermometers, fertility microscopes and saliva tests.

Oxygen Analyzer with External Sensor is ideal for spot-checking or continuous display of oxygen concentration in respiratory care of anesthesiology.

Oxygen Analyzer with Internal Sensor is ideal for spot-checking tank, liquid oxygen systems & oxygen concentrators and connects to oxygen with standard 02 tubing.

Oxygen Monitors and Analyzers include patented technology that warns in advance of sensor expiration. The units include state-of-the-art microprocessor-controlled electronics. It features automatic calibration, on-screen calibration menu/instructions and battery strength indicator.

Pancreatic Amylase is a digestive enzyme secreted by the pancreas. It consists of a single polypeptide chain with a molecular weight of 54 kDa. Pancreatic amylase digests starch to maltose.

Prostatic Acid Phosphatase is an enzyme measured in the blood whose levels are elevated in patients with prostate cancer that has invaded or metastasized. PAP is not elevated unless the tumor has spread outside the anatomic prostatic capsule.

Paraffin wax bath soothes the pain of arthritis, joint stiffness, inflammation, sports injuries, muscle spasms dry and cracked skin. It hydrates and soothes dry skin for a more beautiful appearance, stimulates circulation and relieves pain of sore joints and adjustable temperature control.

Particle sizing instruments includes scanning mobility particle sizer and aerodynamic particle sizer spectrometers. It is used in a wide range of particle sizing research applications where the particle size doesn't exceed 20 µm. The instrument also includes a laser, a detector and a correlator.

Pathogen identification device system scanner is a DNA analysis machines. It can detect several different pathogens, including organisms like anthrax, plague, botulism and E. coli, using PCR or polymerase chain reaction, which immerses a sample in a chemical bath designed to identify the agent. It uses hot air instead of a heated block to amplify DNA.

Identification. An examination gown is a device intended for medical purposes that is made of cloth, paper, or other material that is draped over or worn by a patient as a body covering during a medical examination.

Classification. Class I (general controls). The device is exempt from the premarket notification procedures in subpart E of part 807 of this chapter, subject to the limitations in 880.9. If the device is not labeled or otherwise represented as sterile, it is also exempt from the current good manufacturing practice requirements of the quality system regulation in part 820 of this chapter, with the exception of 820.180, with respect to general requirements concerning records, and 820.198, with respect to complaint files.
