Mittal Meditech Universal Pipette Tips - 200ul Pack of 1000 Pieces (MMMPT01000)

Mittal Meditech Universal Pipette Tips are meticulously engineered for the precise and reproducible transfer of aqueous and viscous liquids within a laboratory setting. These tips are sized for accurate aspiration and dispensing volumes up to 200µL. They are an essential tool for quantitative assays, serial dilutions, PCR setup, and general reagent preparation in all clinical, academic, and industrial research laboratories.

The tips are molded from virgin medical-grade polypropylene (PP), a highly stable thermoplastic polymer known for its inertness and chemical compatibility with a vast array of reagents, solvents, and biological samples. This material is free from detectable nucleases, human DNA, and PCR inhibitors, making it safe for sensitive molecular biology applications. The interior surface of the tip is designed to be highly hydrophobic, which significantly reduces liquid retention, also known as 'dead volume'.

These consumables incorporate a standardized barrel and collar geometry developed for universal compatibility. They establish a positive, low-insertion-force seal with virtually all major brands of manual and electronic pipettors (both single- and multi-channel varieties). The secure fit is critical for maintaining the pneumatic seal necessary to achieve the maximum level of volumetric accuracy and prevent sample loss due to leakage or cross-contamination.

Mounting the Tip: Select the appropriate volume setting on your pipettor. Press the tip barrel firmly and straight onto the pipettor shaft until a secure, airtight seal is achieved. Avoid excessive force, which can damage the pipettor or the tip.

Aspiration (Drawing Liquid): Depress the plunger to the first stop (the measurement volume position). Submerge the tip just below the surface of the liquid. Slowly release the plunger back to the rest position to aspirate the desired volume. Crucially, ensure the tip stays submerged during this process.

Dispensing (Releasing Liquid): Place the tip against the interior side wall of the receiving vessel (e.g., tube or well) at a slight angle. Depress the plunger smoothly to the first stop, pause briefly, and then continue depressing to the second stop (the blow-out position) to expel any remaining traces of liquid.

Tip Ejection: While holding the plunger at the second stop, remove the tip from the receiving vessel by drawing it up the side wall. Release the plunger. Press the ejector button to discard the used tip safely into a biohazard or waste receptacle.
