Glassware
Laboratory glassware is usually made of borosilicate glass, which is resistant to chemicals except hydrofluoric acid. Common types of glassware include beakers for holding solutions, flasks for heating liquids, volumetric flasks for precisely measuring volumes, and pipettes for dispensing precise amounts of liquids. Pipettes can be graduated or volumetric, and are used to transfer reagents and biological samples in clinical testing.
Common Glassware used in Lab
Common glassware used in labs include pipettes, burettes, beakers, flasks, funnels, petri dishes, graduated cylinders, vials, slides, and stirring rods. Proper handling, cleaning, storage, and disposal of glassware is important for safety and accurate experimentation. Glassware must be carefully calibrated by determining the mass of water contained or delivered and converting to volume using water's density, in order to avoid measurement errors.

Blood collection and its types
This document discusses blood collection methods. It describes the three main types of blood collection: venous, capillary, and arterial. Venous blood collection is the most common, involving puncturing a vein with a needle and collecting blood into a tube or syringe. Capillary collection involves a small skin puncture to obtain a small blood sample, while arterial collection is rarely needed and involves puncturing an artery. The document outlines the equipment, procedures, and safety measures for performing venipuncture. It also discusses different types of blood collection tubes and their uses based on the additive used.
Haemocytometer lectuer

It has a special slide with ruled areas divided into squares under a cover glass, allowing cells in a small measured volume to be counted manually. Blood is diluted and pipetted into the chamber. Cells are counted within the squares using a microscope at different magnifications for different cell types. Factors like dilution, counting technique, and chamber quality can introduce errors. The haemocytometer allows standardized counting of red blood cells, white blood cells, and platelets in hematology labs.
centrifuge
This document provides information about centrifuges. It discusses the history of centrifuges, including their invention by Benjamin Robins in the 18th century. It defines a centrifuge as a device that separates heavier and lighter particles through centrifugal force. The document describes the main components and working principles of centrifuges, and discusses different types including fixed-angle, swinging head, continuous tubular, ultracentrifuges, hematocrit, and gas centrifuges. It also outlines common applications and safety procedures for operating centrifuges.
Total leukocyte count - TLC
This document discusses total leukocyte count (TLC), also known as the total white blood cell count. It provides the normal ranges for TLC across different age groups. Leukocytosis is defined as a TLC over 11,000/mm3 and can occur due to physiological or pathological factors. Leukopenia is a TLC below 4,000 cells/cu.mm and can be caused by various infections, bone marrow depression, or drugs. The document then describes the manual hemocytometer method for counting white blood cells using a Neubauer chamber, as well as an electronic method using automated analyzers.
Glassware and volumetric pipette.ppt
This document discusses different types of glassware used in laboratories, including non-volumetric glassware like beakers and flasks, and volumetric glassware like graduated cylinders and volumetric flasks.

The document provides guidance on correctly reading pipette volumes and using pipettes and glassware properly.
Blood collection
Blood can be obtained through venous or capillary puncture for laboratory testing. Venous puncture from the median cubital vein is preferred as it provides a large, undiluted sample for many tests. The procedure involves selecting and cleaning the vein site, inserting the needle at a 30-35 degree angle, collecting blood in an anticoagulant tube, and applying pressure to stop bleeding. Capillary puncture from the finger or heel is an alternative for small volume tests, but carries a higher risk of erroneous results due to dilution or contamination of the sample. Proper patient identification, aseptic technique, and disposal of sharps are important to perform both procedures safely.
