Glass Personal Blender (PBG-5050)
Personal blender with tempered-glass cups and an all-stainless blade assembly - the rare blender where nothing in the blend path is plastic, seals aside.
Plastic-free verdict: Silicone only
The blending containers are tempered glass and the blade assembly (and the blade clutch/coupling) are all stainless steel, so the friction-and-heat blend path is glass and steel only - no Tritan jar to shed microplastics. The travel and storage lids are plastic on the outside but carry a removable silicone lining so the drink contacts silicone, not plastic. That silicone lining is the only non-glass, non-steel food-contact material, which is why this lands at silicone-only rather than fully plastic-free.

What it's made of
| Part | Material | Food contact |
|---|---|---|
| blending / serving cups tempered glass cups; manufacturer states zero plastic food contact | Borosilicate Glass | Yes |
| blade assembly all-stainless blade assembly | Stainless Steel (304 / 18-8) | Yes |
| blade clutch / coupling stainless steel for durability (brand-stated) | Stainless Steel (304 / 18-8) | No |
| travel / tumbler & storage lids plastic lid shell; a removable silicone liner sits between the drink and the plastic | Plastic (other / unspecified) | No |
| lid liner removable food-grade silicone lining so blends never touch the plastic lid | Silicone | Yes |
A single-serve "blend and go" blender built around glass instead of the usual Tritan cups. You blend directly in a tempered-glass cup, flip it onto the motor base, then cap it with a silicone-lined tumbler lid to take it with you. Tribest also sells cheaper Tritan-cup versions of this blender - this is the glass model (PBG series), the one to choose for a plastic-free blend path.
Pros
- Glass cups plus all-stainless blades - no plastic in the friction/heat blend path
- Travel lids use a removable silicone liner so drinks avoid the plastic
- Small footprint; blend-and-go convenience without a Tritan jar
Cons
- Personal-blender capacity only - not a full countertop workhorse
- Glass cups are heavier and breakable
- Lid shells are still plastic (the silicone liner is what keeps drinks off them)
Notes
- Tribest also sells Tritan-cup versions (PB series) and mason-jar-ready models; the PBG glass model is the plastic-free-path one
- Glass model line: PBG-5050 (and PBG-5001 with vacuum); confirm you are buying a glass (PBG) SKU, not a Tritan (PB) one
