What is the widest width of these tips, please? I'm looking for tips that can manage transferring from a bottle with a very narrow neck, 6.35mm

My measurement, they are 7.5mm wide at the top.

Do the 20-200ul pipette tips fit the 10 - 100ul transfer pipette?

Dear client: Hello! Thank you for your question.♥◠‿◠)ﾉ Our Four E's Scientific 20-200ul tips fits Four E's 10 - 100ul single-channel pipette? Because our 20-200ul tip's diameter is 5.3mm =diameter of 10-100ul pipette column, and actually, our 200ul tip can pipette 0~200ul liquid. Our Four E's 10-100ul pipettor is easy to use, easy to control with full hand, reducing hand fatigue.

Do these come in trays ready for multi-channel pipette pick up or are they lose?

Dear customer: Hello! Thank you for your question.♥◠‿◠)ﾉ This 200ul Pipette tips don't come in trays, it is a bag of 960pcs, as 200ul tips are consumables and single-use, many our 200ul pipette customers hign demand for our Four E's Scientific 200ul tips, if every 960pcs tips come with a holder, it may not be environmentally friendly. :-） Our Four E's Scientific tips ensures a better seal with the pipettor module, ensuring higher accuracy and precision; the soft tip reduces the amount of force needed to attach and eject tips, significantly lowering the risk of repetitive stress injury (RSI). we have 1 year warranty period and good after-sale service, and we will offer better service to make you satisfied.
