Liquid storage and dispensing system comprises a storage barrel including a cylindrical bore having an open proximal end and a closed distal end having a port, wherein the port exits the storage barrel through a delivery tip. It is designed for use in the storage, shipping, and accurate dispensing by manual or automated methods.

Lithium is a drug commonly used to treat bipolar disorder and depressive disorders. It is a positively charged element or particle that is similar to sodium and potassium. It interferes at several places inside cells and on the cell surface with other positively charged atoms such as sodium, potassium, calcium, and magnesium, which are important in many cellular functions. It interferes with the synthesis and retake of chemical messengers by which nerves communicate with each other (neurotransmitters). It also affects the concentrations of tryptophan and serotonin in the brain. In addition, it increases the production of white blood cells in the bone marrow.

Luteinizing hormone (LH) is a hormone synthesized and secreted by gonadotropes in the anterior lobe of the pituitary gland. In women, LH helps regulate the menstrual cycle and egg production (ovulation). The level of LH in a woman's body varies with the phase of the menstrual cycle. A LH test measures the amount of luteinizing hormone (LH) in a sample of blood or urine. This test is done to find the cause for a couple's inability to become pregnant (infertility).

Lyme antibody serology test is used to detect antigen in urine from patients with lyme borreliosis. It indicates the presence of both IgG and IgM antibodies to B. burgdorferi. The presence of antibody indicates exposure, not active disease. The IgG/IgM ELISA is the most commonly used screening test for the primary diagnosis of lyme disease.

Lyme disease western blot is a sandwich-type immunoassay that allows visualization of the patient's antibodies. This test must be used if the Lyme IgG/IgM antibody serology is equivocal or positive. The western blot involves a highly complex visual determination of protein bands, based on their molecular weights and intensities. The IgM Western blot is often positive in patients with persistent infection.

Magnesium is an essential mineral for human nutrition. Magnesium in the body serves several important metabolic functions. It plays a role in the production and transport of energy. It is also important for the contraction and relaxation of muscles. It is involved in the synthesis of protein, and assists in the functioning of certain enzymes in the body.

Magnetic stirrers consist of a rotating magnet or stationary electomagnets to create a rotating magnetic field. These stirrers are used to cause a stir bar, immersed in a liquid to be stirred, to spin very quickly, stirring it. These stirrers are often used in laboratories especially in the field of medical exams.

Magnifying Exam Lights provide 22 watts of light and 3x magnification.

Semen analyzer is used to measure the amount and quality of a man's semen and sperm. It is otherwise called as sperm count.

Manual Cryostat features open-top design that minimizes temperature gains, well-illuminated chamber and CFC-free refrigerant & foam insulation.

Manual Microplate Washers consist of a reservoir fitted with multiple channel pipettes that are used to wash multiple-well microplates.

Manual Pipette Racks features four angled compartments, which organize pipette supplies in one location and durable ABS plastic construction with side cutouts.

Manual tissue arrayer allows for relatively easy construction of tissue micro arrays with several hundred specimens.

Measles IgG ELISA kit provides all the necessary reagents for the rapid determination and quantitation of IgG antibody to measles. This kit contains measles virus antigen, serum diluent, calibrator, horseradish peroxidase (HRP) conjugate, chromogen/substrate solution and wash buffer.

Measles IgM ELISA kit is an enzyme-linked immunosorbent assay (ELISA) and it is intended for the in vitro determination of IgM antibody to measles in human serum. It provides all the necessary reagents for the rapid determination of measles virus IgM antibody in human serum, including an absorbent solution.

Mechanical Calibration Kit contains the precision mechanical standards required to calibrate the systematic errors of agilent network analyzers. This kit also contains flush short circuit, a precision shim and a fixed termination.

Medical Examination Lights have weighted caster bases, plug-in transformers and vented shades.
