instruments used in pathology instruments used in pathology instruments used specially in pathology are as follows: instrument list instrumentuses flow cytometerused for automated cell counting as in total blood count, differential count, etc. tissue bath or organ bath or dale's apparatusused in full tissue experiments, for example using guinea pig ileum mainly used in pharmacology for application of drugs to these tissues. sahli haemoglobinometeran old but rapid and simple method of hemoglobin estimation in the laboratories. presently used in some places where sophisticated optical instruments are not available haemocytometera microscope associated apparatus used for manual counting of cells in body fluids like blood, etc. including for sperm count wintrobe's tubeused for esr (wintrobe's method), pcv, haematocrit, etc. westergren's tube and esr standused for esr (westergren's method) disposable plastic molds or embedding molds (leukart's l blocks) for tissue paraffin block making w.r.t. histopathologyused to make blocks of tissue for cutting into thin slices for microscopy block holders (in histopathology)used to hold the tissue blocks during cutting •refrigerated microtome (cryostat)-do-; a special type that is used during operations to aid the surgeon in demarcating the diseased (specially neoplasms) tissue. •rocking microtome-do-; a special type •base sledge microtome-do-; a special type •ultra microtome-do-; a special type tissue section floating baths (in histopathology)used to spread the cut thin slices onto water using surface tension from where it is placed onto glass slides ryle's tube or nasogastric tubeused for nasogastric suction (or at times introduction of food or drugs). video link fnac needlesused for fine needle aspiration of material from inside the body; used for diagnostic examinations of the cells hence obtained; video link trephine biopsy needleused for taking a biopsy from a deep hard tissue like bone marrow (within a hard bone) spirometerused to test lung function; video link •water-seal type-do- •douglas bag type-do- peak flow meter or peak expiatory flow rate meterused to test lung function by testing the rate at which the person can exhale; useful to diagnose copd and asthma mercury or other manometersused to measure pressure of a fluid within a cavity like the spinal canal, which is raised in certain diseases electrocardiogra urinometer estimation of specific gravity of urine. esbach's albuminometer quantitative analysis of albumin in urine sample. gallery a hemocytometer spinal needles marrow puncture bone marrow biopsy needle rotary microtome electrical microtome base sledge microtome hypodermic needle intravenous cannula peak flow meter blood pressure monitor flexible endoscope urinometer
