Overview
A tissue culture technician opens each Costar Stripette from its own paper and plastic wrap, either by pop-through or by peel-apart. The wrap is also said to reduce static cling while gloved.
The reason to buy is sterile packaging for each pipet, which avoids contamination during culture handling, along with a fine graduation interval. The limitation is that the case is single-use polystyrene, so usage adds up quickly with the volume of work, and the listing gives no tolerance data.
Who it's for
Cell culture and tissue culture benches where each transfer needs a fresh sterile pipet. Teaching labs that wash and reuse glass, and anyone needing a few pipets rather than a full case, should look elsewhere.
Pros and cons
- Individually wrapped and sterile
- Two opening methods for the wrap
- Wrap reduces static cling with gloves
- Fine graduation interval
- Large case quantity
- Accuracy tolerance not listed
- Plastic, not glass
Performance notes
Fine graduations let a user read small volume steps along the pipet, and individual wrapping protects sterility until the moment of use. Reduced static cling on the wrap makes it easier to handle with gloved hands.
