Vacuum Desiccators Polypropylene are essential in laboratories, providing a dry atmosphere to protect moisture-sensitive samples from humidity damage. These desiccators ensure sample integrity by maintaining a low-humidity environment.
Desiccators are made of polypropylene and polycarbonate. These autoclavable vacuum desiccators can hold a vacuum up to 740 mm of Hg for 24 hrs without any greasing. The top dome, molded in rigid and transparent polycarbonate, gives a crystal clear view of the desiccant placed inside. The knurled knob on the top provides easy handling of the dome. The lower part is made of polypropylene. An internal groove is provided on the flange to hold a silicon rubber O-Ring. The polypropylene stopcock is fitted with a self-lubricating PTFE plug. This plug works three-way i.e. vacuum creation, shutting off & vacuum releasing.

Great quality but big
Style: Side Sleeper, Pattern Name: King
These pillows seem to be very good quality. I couldn’t wait to try them. I soon realized that they’re very thick & too high for my neck. I can push the pillow down but it doesn’t stay so I’d say they’re too firm for me & don’t support the neck properly because of the height.

my fav now after using 50+ pillows
Style: Back Sleeper, Pattern Name: King
I have always struggled to find the perfect pillow, and so far I have had 50+ pillows. Personally, I like my pillow to be on thinner side as I look for more support for my neck.
This is my first time buying pillows online, because I like to physically touch and feel the firmness and thickness before I purchase my pillows. I am so glad I did it! These pillows are just PERFECT for me! Perfect firmness, perfect thickness and perfect material.
One thing I suggest is that be extra cautious when you open the package. These pillows were rolled and put in a relatively thin shipping bag, so when you open with sharp objects be careful not to cut your new favorite pillows!
I let the pillows sit for about 48 hours before I started using them, but I assume you don't have to wait that long.
Overall, I am very happy with my first online pillow purchase with Serta!
