These tube racks are made from heavy-duty polypropylene and feature a unique system of tabs and slots, which facilitate easy connection and a sturdy fit. Autoclavable. Each rack can hold different sized tubes on each side, Side 1 ( 4 - 50mL tubes), Side 2 (12 - 15mL conical tubes), Side 3 (32 - 1.5/2.0mL tubes), Side 4 (32 - 0.5mL microtubes).Specifications: Dimensions: 6.85 x 3.74 x 2.04 in (17.4 x 9.5 x 5.2 cm), Quantity: 5 per pack, Color: Assorted, Blue, Green, Pink, Yellow, Orange Review: Can easily be used for any type of tube volume you're looking for (including O-ring tube caps). - Whether is 500ul, 1.5ml, 15ml or 50ml tubes, this classic and nostalgic tube racks will easily have you covered. It is the most overused tube rack in my laboratory and I have a lot of these. It seems that no matter how many of these we have, they almost always all get used up during the entire working day of experiments. Each side of the tube rack has different-size holes to account for your specific needs in sample preparations. I have overused these tubes during my PhD and continue to use them afterwards and it really captures the nostalgic feel while also being very helpful. It can be use for O-ring tubes in the side that holds 1.5ml eppendorf (or any 1.5ml) tubes. I have used these for western blot where it holds the O-ring prestained ladders from Biorad and works perfectly alongside my samples. I have also used it for cryogenic vials with O-ring tubes (although for cryogenics vials, I would maybe use another type of rack since those O-ring screw caps comes in a variety of volumes and some may exceed the classic 1.5ml volume). Depending on the cryogenic vial that you have, it may or may not fall right through. In my case, it tends to hold in place but test it out first before going to place it on this rack. Finally, one small rant that I have for this tube rack (but not enough to lower its star rating since I am used to it) is that whenever you are using 15ml tubes, have in mind that its lower bottom will fall right through the section of 50ml tubes. Since the hole of 50ml tubes is much larger than the 15ml, the bottom tip of the tube it will easily fall through slightly BUT it will stay in place due to its screw cap. Trust me, it will stay in place but it will wobble a lot when moving the test tubes. It is slightly annoying when you have a lot of samples in 15ml tubes and you need to be very careful for any type of sudden motion (such as a cell sediment pellet in the cell supernatant). You can also freeze your sample at -80℃ with these test tubes (as shown in the attached image). Review: These do a good job especially for holding microcentrifuge tubes - as advertised. These do a good job especially for holding microcentrifuge tubes. Not so good for 15 or 50 ml tubes, but they will work in a pinch. ## Features - Create as large a rack as you need by linking together multiple racks - Heavy-duty polypropylene racks feature a unique system of tabs and slots, which facilitate easy connection and sturdy fit - Autoclavable - Each rack can hold different sized tubes on each side, Side 1 ( 4 - 50mL tubes), Side 2 (12 - 15mL conical tubes), Side 3 (32 - 1.5/2.0mL tubes), Side 4 (32 - 0.5mL microtubes) - Conveniently connect end to end or side to side ## Technical Specifications | Specification | Value | |---------------|-------| | Customer Reviews | 4.6 out of 5 stars 74 Reviews | ## Images ![Heathrow Scientific HS29022G Interlocking 4 Way Tube Rack, Polypropylene, Assorted Colors (Blue, Green, Pink, Yellow, Orange), Pack of 5 - Image 1](https://m.media-amazon.com/images/I/810hKa+P7SL.jpg) ![Heathrow Scientific HS29022G Interlocking 4 Way Tube Rack, Polypropylene, Assorted Colors (Blue, Green, Pink, Yellow, Orange), Pack of 5 - Image 2](https://m.media-amazon.com/images/I/81FMSBTWMhL.jpg) ![Heathrow Scientific HS29022G Interlocking 4 Way Tube Rack, Polypropylene, Assorted Colors (Blue, Green, Pink, Yellow, Orange), Pack of 5 - Image 3](https://m.media-amazon.com/images/I/619MmXPk54L.jpg) ![Heathrow Scientific HS29022G Interlocking 4 Way Tube Rack, Polypropylene, Assorted Colors (Blue, Green, Pink, Yellow, Orange), Pack of 5 - Image 4](https://m.media-amazon.com/images/I/61UiUMxIinL.jpg) ## Questions & Answers **Q: Which side holds 15ml?** A: The side pictured here.
