R510-31-6

RWD Gas Filter Canister

Disposable activated-charcoal canister that captures waste isoflurane, sevoflurane and enflurane before they re-circulate into the room — the workhorse scavenging consumable for vivarium and veterinary anesthesia stations. Two sizes (Large: 200–240 g capacity; Small: 50 g capacity) ship in 6- or 16-pack quantities.

What is the RWD Gas Filter Canister?

The RWD Gas Filter Canister is a disposable activated-charcoal canister used to capture waste anesthetic gases — isoflurane, sevoflurane, enflurane and other halogenated agents — before they re-circulate into the room. It pairs with passive scavenging setups and as a back-up filter on active scavenging systems like the R546-Pro, providing a compliance-grade adsorption layer that protects vivarium and procedure-room personnel from chronic exposure.

Two canister sizes are offered: a large variant (800 g net weight) rated to capture 200–240 g of anesthetic gas, and a small variant (250 g net weight) rated to capture 50 g — sized to match low-flow vs. high-throughput workflows. Both ship in pre-packaged multi-canister quantities.

Key Features

Disposable activated-charcoal cartridge: Replace when saturated — no servicing, no regeneration cycles to schedule.
Captures all common halogenated agents: Effective on isoflurane, sevoflurane and enflurane.
Two sizes: Large (800 g / 200–240 g capacity) and small (250 g / 50 g capacity) so canister change frequency can be matched to the workflow.
Multi-pack delivery: Ships as 6-packs (large or small) or 16-packs (small) — ideal for vivarium stockrooms.
Passive or backup scavenging: Use stand-alone with passive scavenging tubing, or as a polishing filter on active scavenging systems.

Why active charcoal scavenging matters

Chronic exposure to halogenated anesthetic gases has been linked to occupational health concerns including headaches, fatigue and reproductive risks among laboratory staff. NIOSH and OSHA recommend keeping ambient concentrations of halogenated agents below 2 ppm — a level that essentially requires active or passive scavenging at every anesthesia station.

Activated-charcoal canisters like the RWD Gas Filter Canister are the workhorse of small-animal scavenging. They capture volatile anesthetic agents on a high-surface-area carbon bed before any exhaust returns to the room. Because each canister has a finite saturation capacity (200–240 g for the large, 50 g for the small), vivariums typically inventory canisters by the pack and rotate them on a documented schedule — part of routine occupational-safety compliance.

Typical Use Cases

Passive scavenging for rodent stereotaxic surgery suites and behavioral pipelines.
Back-up filtration on active scavenging systems (e.g. R546-Pro Gas Evacuation Apparatus).
Veterinary anesthesia in dental, dermatology and soft-tissue procedure rooms.
Imaging suites running animals under prolonged inhalation anesthesia.
Compliance-driven scavenging stock for shared vivarium use.
