Breathing Circuit – Mapleson F (Jackson Rees Modification, Paediatric)
Caesarean Section (CS) Set – Major
The Major CS Set is made from high-quality medical-grade stainless steel, ensuring durability, corrosion resistance, and complete sterilizability. All instruments are autoclavable and arranged in a sterilizable stainless-steel tray or container for easy handling in the operating theatre.
It is designed to meet the needs of obstetricians and surgeons performing caesarean deliveries under sterile surgical conditions.
Caesarean Section (CS) Set – Minor
The Minor CS Set is made from high-quality medical-grade stainless steel to ensure durability, corrosion resistance, and easy sterilization. The instruments are autoclavable, allowing repeated use while maintaining sterility.
The set is organized in a sterilizable tray and includes instruments for cutting, grasping, clamping, retracting, and suturing.
Calcium Hydroxide
Calcium Reagents
Principle of Measurement
1. Arsenazo III Method (Most widely used in modern analyzers)
How it works:
-
Calcium ions react with Arsenazo III dye to form a blue-purple complex.
-
The intensity of the color is measured photometrically at 650–660 nm.
-
Highly specific for calcium with minimal interference from magnesium.
Advantages:
-
Excellent stability
-
Strong absorbance
-
High specificity and precision
2. o-Cresolphthalein Complexone (OCPC) Method
How it works:
-
Calcium forms a purple-red complex with o-cresolphthalein complexone in alkaline conditions.
-
Read photometrically at 570–580 nm.
-
Common in semi-auto chemistry analyzers.
Advantages:
-
Reliable and widely established
-
Suitable for manual and automated systems
