  • Design and Features The volumetric flask in question is made of high-quality glass, typically borosilicate, known for its chemical resistance and durability. It has a flat, stable base, a long, narrow neck, and a bulbous body. The distinguishing feature of this type of volumetric flask is the single graduation mark on the neck, indicating the calibrated volume with high precision. The "one mark" design ensures that the flask is specifically calibrated for a single, accurate volume, which helps maintain consistent measurement standards in laboratory experiments. This particular flask comes with an interchangeable LDPE (Low-Density Polyethylene) stopper. The use of LDPE material is advantageous because it is chemically inert, providing good resistance against various chemicals, making it suitable for most laboratory purposes. LDPE stoppers are also flexible, providing a snug fit that prevents the evaporation of volatile substances and contamination from external sources. The stopper can be easily interchanged between compatible flasks, allowing flexibility and practicality when working with multiple flasks. The flask is classified as "Class A," which is a standard of accuracy defined by the International Organization for Standardization (ISO) and other regulatory agencies. Class A volumetric flasks have the highest level of accuracy and precision compared to other classes, such as Class B. The tolerance levels of Class A volumetric flasks are much lower, making them suitable for tasks that require critical accuracy, such as titrations and preparing standard solutions. Class A volumetric flasks are often supplied with a calibration certificate that indicates the flask has been individually tested and verified to meet the required specifications. Uses and Applications The primary use of a volumetric flask with a one-mark calibration is to prepare and dilute solutions to a precise volume. The accuracy offered by the Class A designation ensures that the concentration of the solution can be precisely controlled, which is essential for quantitative chemical analysis. Preparation of Standard Solutions: Volumetric flasks are commonly used to prepare standard solutions, which are solutions of known concentration used for analytical purposes, such as titration or calibration of analytical instruments. The one-mark design makes it possible to achieve a specific volume accurately, ensuring the reliability of the prepared standard solutions. Dilution of Solutions: In analytical chemistry, a concentrated solution often needs to be diluted to a specific volume. The volumetric flask’s precise calibration allows the chemist to perform accurate dilutions, maintaining the desired concentration of the resulting solution. This feature is essential when dealing with highly sensitive experiments where even a slight deviation can affect the outcomes. Quality Control and Analytical Chemistry: Industries such as pharmaceuticals, food and beverage, and environmental testing often require precise measurement and preparation of solutions. Class A volumetric flasks are employed to maintain quality control and ensure consistency in analytical results. Chemical Reactions and Assay Preparation: For quantitative chemical reactions, the concentration of reactants must be controlled to obtain the desired yield. Volumetric flasks allow the accurate preparation of reactants, aiding in the reproducibility of chemical assays and experiments. Advantages of Interchangeable LDPE Stopper The interchangeable LDPE stopper provides a number of benefits to the volumetric flask: Chemical Compatibility: LDPE is resistant to many common chemicals, including acids, bases, and alcohols. This makes it a versatile material suitable for a wide range of laboratory applications. Unlike glass stoppers, LDPE stoppers do not react with most substances, ensuring the integrity of the solution being stored. Secure Seal: The flexibility of LDPE allows the stopper to form a tight seal, preventing the evaporation of volatile chemicals. This ensures the concentration of the solution remains consistent over time. The stopper also prevents contaminants from entering the flask, which is particularly important when preparing analytical-grade solutions. Ease of Handling: The stopper can be easily removed and replaced, allowing convenient access to the contents of the flask without compromising accuracy. Additionally, since the stopper is interchangeable, it can be used with multiple compatible flasks, adding to the versatility of laboratory operations. Calibration and Accuracy Class A volumetric flasks are typically calibrated "to contain" (marked as "TC") or "to deliver" (marked as "TD") a specific volume at a defined temperature, usually 20°C. The calibration accounts for the expansion or contraction of the glass at different temperatures, which can affect the volume measurement. The single graduation mark on the neck of the flask allows the user to accurately fill the flask to the specified volume. Class A flasks are manufactured with strict quality control measures to ensure their accuracy. These flasks are often individually tested and come with a certificate of calibration, indicating that the flask meets the tolerance limits set by ISO or ASTM standards. The accuracy provided by Class A volumetric flasks is essential for critical applications, such as preparing solutions for titrations or instrumental analysis, where the precision of the concentration directly affects the outcome. Handling and Maintenance Proper handling and maintenance of volumetric flasks are crucial to preserving their accuracy and longevity: Cleaning: Volumetric flasks must be thoroughly cleaned and rinsed before use to avoid contamination of the solution. Any residual chemicals can alter the concentration of the prepared solution. The flask should be rinsed with deionized water and, if necessary, with a small amount of the solution that will be used. Storage: The flask should be stored with the stopper in place to prevent dust and contaminants from entering. When not in use, the stopper should be kept loosely in the neck of the flask to avoid stressing the neck. Temperature Considerations: Since volumetric flasks are calibrated at a specific temperature, it is important to consider temperature changes that can affect the volume. Solutions should be allowed to reach room temperature before measurements are made to ensure accuracy. VOLUMETRIC FLASK ONE MARK WITH INTERCHANGEABLE LDPE STOPPER, CLASS ‘A’
  • PM-494 TISSUE CULTURE RACK Tissue culture is the growth of tissues or cells in an artificial medium separate from the parent organism. This technique is also called micro propagation. This is typically facilitated via use of a liquid, semi-solid, or solid Growth medium, such as broth or agar. Tissue culture commonly refers to the culture of animal cells and tissues, with the more specific term plant tissue culture being used for plants. Tissue culture rack are very useful for various types of tissue culture plants and other tissue culture work in tissue culture room Tissue culture rack made of Mild steel  tubular pipe frame / Mild steel  slotted angle frame as may be required.
