Warner VPP Perfusion Pressure Kit

Drop-in pressurization kit that upgrades any gravity-feed Warner perfusion bench to a stable pressurized system. Dual regulators (20 psi input + 0.1 psi delivery accuracy) drive solution from BD syringe reservoirs at precisely the same low flow rate every time. Universal plug fits 5/10/20 cc syringes; large plug variant fits 60 cc syringes. Pairs with the Warner VCS.

Warner Perfusion Manifolds (MP / MPP / MM / ML Series)

Low-dead-volume (3.5–5 µL) perfusion manifolds that converge 2–8 input lines into a single chamber line. Four series: MP for gravity, MPP for pumped/pressurized, MM and ML for SF-77 fast-step low-volume work. PTFE or Delrin construction, chemically resistant and autoclavable. The essential link between the Warner VCS and the recording chamber.

Warner Tubing & Connector Kit (Barb and Luer)

Complete plumbing kit for Warner imaging and recording chambers — polyethylene tubing in all 4 sizes (PE-10, PE-50, PE-90, PE-160), C-Flex pinch-valve tubing, blunt-end syringe needles in 4 gauges, Luer-PE-50 adapters, and T-style Luer-Luer fittings, all in polypropylene. The one-purchase replacement for a dozen separate POs when setting up or maintaining a perfusion bench.

Warner DWV Dedicated Workstation Vacuum System

Self-contained bench-top vacuum for chamber aspiration — medical-grade linear-piston pump, twin 2 L flasks (trap + reservoir), needle-valve trim, vacuum gauge. 40 dB(A) low-noise, continuous-duty, universal 92–250 VAC. Designed for labs without in-house vacuum, or with unstable house vacuum that disrupts patch-clamp and live-cell imaging aspiration.

L-VIS (Low Volume In-Vitro Slice Chamber)

The L-VIS (Low Volume In-Vitro Slice Chamber) from PopNeuron is a patented recording chamber that reduces ACSF volume to just 1.5–2 ml per experiment—the lowest of any design on the market. By eliminating external reservoirs entirely and using an internal water pump for figure-8 recirculation, it dramatically reduces pharmacological reagent costs and pays for itself in 1–3 experiments.

Optogenetics App

The Optogenetics App (and Optogenetics Pro) by PopNeuron is a free iOS and Android application that calculates required laser power for in-vivo optogenetic experiments. Using a validated light-scattering model calibrated across seven mouse brain areas, it outputs penetration depth as a function of optical power for any brain region, opsin, and fiber combination—essential for planning effective and safe optogenetic stimulation.
