Borosil Thermo Vacuum Flask – 500 ml (Blue) (Grade 304 SS, 24-Hour Hot & Cold)
The Borosil Thermo Vacuum Flask – 500 ml in Blue is a vacuum-insulated stainless steel flask from Borosil's Hydra range — a calm, refreshing blue colour with a carry jacket that can be oriented horizontally or vertically. Constructed from Grade 304 (18/8) food-grade stainless steel inside and outside, the flask is rust-proof, odour-free, and non-reactive with any hot or cold beverage. Its copper-coated double-wall vacuum interior keeps beverages hot or cold for up to 24 hours — a performance level suited to long office shifts, travel days, and outdoor use. At 500 ml, it carries enough for multiple servings without needing a refill, and the cap doubles as a convenient drinking cup. Borosil provides a 1-year warranty on this flask against manufacturing defects.
The Borosil Thermo series features a distinctive carry jacket that can be adjusted for both horizontal and vertical carry — a practical design feature for those who pack their flask in a bag on its side or slip it into a bag pocket upright. The flip-top lid is leak-proof and enables controlled pouring without fully removing the cap, reducing spill risk during movement. To maximise performance, Borosil recommends pre-conditioning the flask with hot water before filling for hot beverages, or with cold water before cold use. The flask is not suitable for carbonated drinks. The blue powder-coated finish gives it a clean, stylish appearance suitable for offices, hospitals, travel, and daily personal use.
Key Features
Grade 304 SS with Copper-Coated Double-Wall Vacuum Insulation
Food-grade 18/8 stainless steel inner and outer walls combined with copper coating and vacuum insulation deliver up to 24 hours of hot or cold temperature retention. The exterior stays condensation-free, preventing wet bags and surfaces during carry.
500 ml Capacity — Multi-Serving Hydration
The 500 ml capacity holds enough for several cups of tea, coffee, or water — suitable for a full morning of office work, a day's worth of travel sips, or multiple servings at a picnic without needing to refill.
Flip-Top Leak-Proof Lid with Cap-as-Cup Design
The flip-top lid is leak-proof for safe bag carry, and the cap unscrews to function as a drinking cup — a practical, no-extra-crockery feature for sipping tea or coffee on the move.
Unique Adjustable Carry Jacket — Horizontal or Vertical
The carry jacket that comes with this flask can be oriented for both horizontal and vertical carry — ideal for those who carry their flask in a bag pocket upright or slung over a shoulder in a flat position.

All plastic components are BPA-free; the steel body is rust-proof and food-safe. Borosil provides a 1-year warranty against manufacturing defects, backed by the brand's customer care network across India.
