Lavage systems are of considerable value when frequent topical treatment of the eye is required. It can be inserted in the sedated conscious horse following infiltration with local anaesthetic, or at the end of any surgical procedure under general anaesthesia. These devices are made commercially and two types are available: single entry and double entry. The single entry type has a footplate, which surrounds a small central hole at the end of the delivery tubing; the double entry type has two holes located in the distal part of the delivery tubing. Lavage systems can also be made from pliable polyethylene tubing of minimum length 20 cm, which is then positioned in the upper eyelid using a trochar or a large 12-14 gauge needle from which the hub is removed.

Leg positioner frees the OR staff to be more productive. It eliminates the need for 2nd assistants to hold the leg, while enabling surgeons and staff to focus on the procedure instead of leg positioning. It allows the surgeon to place the leg in any position required for knee surgery and have it automatically lock in place. An ergonomic unlocking lever allows the leg to be easily repositioned by grasping the leg and moving it to the desired location where it automatically locks.

A laminar airflow system is an unidirectional ventilation system in which filtered, bacteria-free, ultraclean air is circulated over the patient from a filtered outlet and returned through a receiving air inlet. Air is filtered through high efficiency particulate air filters that remove all particles equal to or greater than 0.3 microns with an efficiency of 99.7%. It can deliver upwards of 200 air exchanges an hour. It is used most often for procedures such as total joint replacement.

Lab Information System is a class of software, which handles receiving, processing and storing information generated by medical laboratory processes. These systems interface with instruments and other information systems such as hospital information systems. Lab information system is a highly configurable application, which is customized to facilitate a wide variety of laboratory workflow models. Laboratory information systems are part of an integrated informatics solution, which involve many disparate applications. Laboratory information systems designs and manages the complex computer systems that allow physicians and other caregivers to see the results of laboratory tests as soon as they are available.

Lumbosacral Back Braces are utilized to provide support to the lumbar and sacral aspect of the spine. These braces provide added support for patients who suffer from lumbosacral pain due to muscle sprains, disc herniations, facet joint arthritis, spinal arthritis, post back injury & fracture.

Light Guides offer an alternative to lenses and mirrors for transporting beams of light through space or transferring images. Light guides are used for transporting and distributing light over distances. These light guides are used to illuminate the dials on radios and in cars. It is typically constructed from acrylic plastics such as lucite.

Laminar Flow Hoods are ideal for moving semiconductor components or bio/pharmaceutical samples from one controlled environment to another. It has stainless steel and plastic designs in many size and chamber configurations. These hoods include on-board rechargeable power cell, which ensures uninterrupted filter/fan operation for up to 90 minutes. Laminar flow hoods are designed to protect biological specimens and material by bathing the work area with particle free air. Laminar flow hoods prevent particle contamination when filling or packing products.

Laboratory Incubator features door gasket, silicone rubber, ventilation slide and heating up time to 37°C. Laboratory incubators range in size from 2 -12 cu.ft. It uses a gravity convection heating system coupled with a hydraulic thermostat to provide efficient heating.

Large Capacity Incubator Shaker comprises models with varying incubation, refrigeration, illumination and programming capacities, including models with dual temperature programming and automatic shaking shut-off to limit metabolic activity at the end of a run. It includes self-correcting feedback controls, acceleration control, humidity control, light & temperature programming and a nonvolatile memory.

Laboratory Freezers are designed for medical and scientific applications such as storage of reagents, pharmaceuticals and biologicals. Laboratory freezers offer temperature ranges of -20ºC to 30ºC and 40A oversized refrigeration. It is available in automatic defrost units for routine storage and manual defrost units for enzyme storage. It features all-steel construction, a counter-balanced lid, indicating temperature control and air-cooled condenser.

Glass Door Laboratory Refrigerators are designed for oversized refrigeration (134A) at a temperature range of 0ºC to 10ºC. It features chemical resistant vinyl clad steel, white anodized aluminum with 300 series stainless steel floor, oversized refrigeration, positive seal self-closing doors, foamed-in-place polyurethane high density cell insulation and safety shielded fluorescent interior lighting.

Laboratory Grade Water Purification System employ reverse osmosis to remove 95% of all major contaminants, which produce laboratory grade water for applications such as glassware rinsing. It features 16X2 characters backlit digital display, built in ROM, RAM & CPU microprocessor and water quality display for both RO & ultra pure water.

Lithotripsy Systems are used to disintegrate calculi such as kidney, bladder, ureter or gall stones. Lithotripsy systems use percutaneous or transurethral endoscopic stone removal techniques.

Leptospirosis Test Kits contains test cells, control cells and positive & negative controls.

Laryngeal Mirror is a stainless steel instrument with removable octagon threaded handle. These mirrors are sterilized by boiling. These laryngeal mirrors are made to the highest standards using chrome-plated non-ferrous alloys.

Lightning Detector is a device that detects lightning produced by thunderstorms. There are three primary types of detectors such as ground-based systems using multiple antennas, mobile systems using a direction & a sense antenna in the same location and space-based systems. Lightning detectors are classified according to size, capacity and installation location & methods.

Lip Balm is a substance applied to the lips of the mouth to relieve chapped or dry lips, angular cheilitis or stomatitis and cold sores. Most lip balms contain sunscreen to minimize sun damage. The primary purpose of lip balm is to provide an occlusive layer on the lip surface to seal moisture in lips and protect them from external exposure.

Lozenge is a small, medicated candy intended to be dissolved slowly in the mouth to lubricate and soothe irritated tissues of the throat possibly from the common cold or influenza.
