Preparative ultracentrifuges are general-purpose centrifuges. It is ideal for the wide range of separation tasks used in cell biology, biochemistry and molecular biology. It incorporates automatic rotor-life management; a large color LCD display and positive-feedback touch pad entry for reliability and efficiency to match their speed and quiet operation.

Retinometer is a laser interference instrument for determination of the visual acuity of the human eye. It has interference optical system for producing an interference light pattern mounted on a slit lamp microscope disposed on an instrument support that is finely adjustable horizontally and in height. This interference optical system consists of a laser light source and a rotatable turntable carrying a plurality of plane parallel plates or wedge plates which may be selectively moved into the light path of the laser light source to produce different interference patterns to be projected onto the human eye and which are then observable through the slit lamp microscope.

A pressure bandage slows down the movement of both tissue fluid and blood near the surface. This prevents the venom from rapidly reaching the bloodstream and is very effective treatment as long as the patient is kept still.
