25-Hydroxy vitamin D test measures the amount of 25-hydroxy vitamin D in the blood. It is the most accurate measure of the amount of vitamin D in the body. This test is used to determine if a person has a deficiency or excess of vitamin D.

8 Channel Elisa Plate Reader is an eight-channel photometer for the sequential and simultaneous reading of micro-plate strips with 96 wells. It features tungsten lamps, 8 silicon photodiodes, 8 independent channels, mono or bichromatic reading, RS232 serial port and power supply of 230/115 VAC, 50-60 Hz and 110 W.

Angiotensin Converting Enzyme Inhibitors are medicines that block the conversion of the chemical angiotensin I to a substance that increases salt and water retention in the body. ACE inhibitors are used in the treatment of high blood pressure. They are used alone or in combination with other medicines for high blood pressure. The ACE inhibitors are drugs that inhibit the formation of angiotensin II and are used for blood pressure control & congestive heart failure. The ACE inhibitors include benazepril, captopril, lisinopril, quinapril and ramipril.

Acetylcholine Receptor is an integral membrane protein that responds to the binding of the neurotransmitter acetylcholine. Acetylcholine receptor antibody is a substance found in the blood of people with myasthenia gravis. The antibody attacks receptors for a chemical called acetylcholine, which sends signals from nerves to muscles and between nerves in the brain.

Acrylic Glove Dispensers feature lids to keep gloves clean & protected with each lid opening independently. Acrylic glove dispenser allow user to see the type and size of disposable glove that is available. It is used in medical, dental, food or industrial applications.

ACTH is secreted from the anterior pituitary in response to corticotropin-releasing hormone from the hypothalamus. Corticotropin-releasing hormone is secreted in response to many types of stress, which makes sense in view of the stress management functions of glucocorticoids. Corticotropin-releasing hormone itself is inhibited by glucocorticoids, making it part of a classical negative feedback loop. Within the pituitary gland, ACTH is produced in a process that also generates several other hormones.

Adjustable waveform ultrasonic cleaners feature unique patented circuitry that converts the conventional ultrasonic sinusoidal waveform to a square digital waveform. The square digital waveforms produce an adjustable reproducible cavitations response. Cavitations in a solution occur at the threshold frequency-the frequency at which a portion of the solution transforms into its vapor phase. Upon exceeding this threshold, countless minute vacuum bubbles form and then violently implode, causing a scrubbing action. The time spent above the threshold of cavitations determines the aggressiveness of the cleaning action.

Adjustable-Volume Pipettors features autoclavable tip cone & lower section assembly, turn plunger for easy volume setting, click sound at each increment, ergonomic, lightweight design & soft plunger movement for user comfort and streamlined tip ejector designed for access to narrow necked containers & tubes.

Adrenocorticotropic Hormone is a polypeptide hormone produced and secreted by the pituitary gland. It is an important player in the hypothalamic-pituitary-adrenal axis. Adrenocorticotropic hormone stimulates the adrenal cortex. ACTH is secreted from the anterior pituitary in response to corticotropin-releasing hormone from the hypothalamus.

Advanced Inverted Microscope System is used for cell imaging. It has a unique two-tiered, multi-port design for maximum flexibility. The system offers highly precise temperature control & resistance to heat and vibration. It is an ideal system for live cell imaging, patch clamp, time-lapse experiments, IVF, TIRF and other advanced applications.

Advanced smart tissue processor is a fully enclosed, stand-alone system for processing of cassette-embedded samples. It combines tissue processing with other useful features such as a user interface, color touch screen, powerful software, real-time remote application, and service support.

Aerosol Delivery System comprises a container defining a chamber for a product to be delivered, an outlet from the chamber, a valve for controlling passage of product through the outlet & a pump for pressurizing product to be delivered.

Albumin is the protein of the highest concentration in plasma. It refers generally to any protein with water solubility, which is moderately soluble in concentrated salt solutions, and experiences heat coagulation. It transports many small molecules in the blood. It is important in regulating blood volume by maintaining the osmotic pressure of the blood compartment, and bind bilirubin, free fatty acids, calcium and some drugs.

Albumin Marker is bromphenol blue which binds to albumin. The marker is added to the normal human serum control so the control is used as a migration marker in immunoelectrophoresis procedures. The control is a stabilized liquid prepared from pooled normal human serum for use as a normal control serum for immunoelectrophoresis procedures.
