Frequently asked questions
Common questions about UNITED SCIENTIFIC from 3G Electric.
What materials are used in UNITED SCIENTIFIC pipette tips and serological pipettes?
UNITED SCIENTIFIC pipette tips are made from polypropylene, a material known for its clarity and chemical resistance, suitable for single-use liquid handling. Serological pipettes are manufactured from polystyrene, which provides dimensional stability and optical clarity for accurate volume measurement. Both materials are standard in laboratory consumables and are not autoclavable for the pipette tips, indicating they are designed for sterile, disposable applications.
Are UNITED SCIENTIFIC pipette tips supplied with filters?
Yes, UNITED SCIENTIFIC pipette tips in the product range, such as the 10 µL, 200 µL, and 1000 µL capacities, include filters. These filters help prevent aerosol contamination and protect pipette shafts from liquid ingress, making them suitable for PCR and other sensitive applications. The tips are preconfigured in racks for convenience and are sterile, ensuring they are ready for immediate use in controlled environments.
What is the sterility status of UNITED SCIENTIFIC serological pipettes?
UNITED SCIENTIFIC serological pipettes, including the 1 mL, 2 mL, and 10 mL capacities, are sterile and individually wrapped. This packaging ensures each pipette remains contamination-free until use, which is critical for cell culture and microbiological work. The pipettes are made from polystyrene and feature 0.1 mL graduation increments for precise dispensing.
Can UNITED SCIENTIFIC petri dishes be used for cell culture?
UNITED SCIENTIFIC petri dishes, such as the 65 mm diameter glass dish with lid, are non-sterile and have no surface treatment. They are suitable for general laboratory applications like sample storage, observation, or non-sterile procedures. For cell culture, sterile dishes with treated surfaces are typically required, so these dishes are not recommended for that purpose unless sterilized by the user.
What is the capacity of UNITED SCIENTIFIC vial racks?
UNITED SCIENTIFIC vial racks, like the polypropylene model in blue, hold up to 50 vials with a diameter of 29 mm. The rack dimensions are 6 7/8 inches wide, 1 1/4 inches high, and 13 1/2 inches long. Made from polypropylene, it offers chemical resistance and durability for organizing samples in freezers or on lab benches.
