1.5ml Microcentrifuge Tubes with Snap Cap, Polypropylene Graduated, 500 Pcs Sterilized Clear Plastic Small Vials with Caps for Sample Storage Without Leakage

💕

Have done quite a bit of breeding my smoking plants. Seeds are overpriced and I’ve gotten 100s from making my own. Needed something to store the seeds and found these. I also purchased seed binder with vials and desiccant beads. Seeds go in these tubes, tube fits in the larger vial from seed binder with desiccant beads. Keeps the seeds very dry and extends shelf life and viability over time. I fit 25 of these seeds into each tube which makes keeping count very simple.

love these

I just received today and they are as described and meet my needs. I would recommend to someone needing this type product!

I disliked the "sterile tube's " were not sterile. Some containers lids were off and not in sterile condition.

These are just what we needed (though not really 1000 of them) for irradiating plasmid samples. The sample was a very small volume and the irradiation source imposed some size restrictions so the 0.5 ml size is perfect. These tubes are uniform in size and the caps shut securely.

Not good

When I received the tubes, right away I realized it would not fit my needs. I needed a tube with an inside diameter of 1/2" to 5/8" Didn't show any ID only a OD that wasn't the actual tube size but rather the size of the flange on top. Luckily I wasn't charged for them or I would have had a thousand tubes I probalby would never have used. The other problem was I couldn't get a return label to send them back!
