Is a serological pipette precise?
Yes, serological pipettes are considered precise volumetric pipettes. Here are some key reasons why: Calibrated accuracy: Serological pipettes are factory-calibrated to deliver volumes within +/-1% of their marked capacity. This tight tolerance ensures high precision. Positive displacement design: They employ a positive displacement pipetting mechanism where a constant volume is drawn in and dispensed in […]
Are serological pipettes Class A?
Yes, serological pipettes are considered Class A volumetric pipettes. The different classes of volumetric pipettes are defined based on their accuracy and performance specifications: Class A pipettes: These provide the highest level of accuracy, typically within ±1% of the graduation value. Serological pipettes fall under this class due to their high degree of precision. Class […]

What is the difference between PET and PETG water bottles?
The main differences between PET and PETG bottles are: Material composition – PET is made from polyethylene terephthalate, while PETG contains glycol modifiers that make it more flexible and impact-resistant than standard PET. Strength and stiffness – PET is stronger and stiffer than PETG. PET retains its shape better but is more brittle. PETG is […]
What is Petg Reagent Bottle?
Here are a few tips for a reagent bottle from PETG: PETG is suitable for chemical resistance and can withstand many lab reagents. However, it’s not as chemically resistant as materials like polypropylene. Test your PETG sample with the specific chemicals first. Use 100% infill for maximum strength. PETG can still absorb liquids over time […]
