".2mL PCR tubes"

Easy-to-use hand vacuum pump without gauge.

Ideal choice for a wide range of laboratory aspirating applications.

Because fumes and corrosive filter agents do not affect this aspirator, it can be used safely with bases, acids, and strong chemicals. The pump fits any standard laboratory faucet and accepts tubing up to 9.5mm ( 3/8") ID. Operates efficiently on normal water pressure above 11 psi.

This lightweight polypropylene pump provides a constant vacuum when hooked to a standard faucet; it operates efficiently with water pressures as low as 7.5 psi for minimum water consumption. It has a maximum free-air pumping capacity of 11.5 liters per minute at a water-flow rate of 6.5 liters per minute. Ultimate vacuum: 28.5" Hg. Supplied with integral check valve, 3/8" NPT connecting thread, and 4 3/4" length of tubing for insertion in discharge end.

Economy blue hand vac pump for experiments in air pressure, vacuum filtration, and leak checks.

This bourdon style vacuum gauge features a 2" Dial with a range of 30-0" Hg.

The VWR® Vacuum aspiration system is designed for laboratory waste recovery and the separation of liquids and solids

Demonstrate many exciting low-pressure phenomena in your physical science classroom.

Ideal for vacuum filtrations under both high and low water pressure.

Constant flow air sampling pump features clear external filter housing allows an immediate visual inspection of filter’s condition. The flow fault indicator lights up if unit operates outside ±5% of set flow rate. Battery test indicator lights up when battery can provide a minimum of 8 hours of operation over operating range.
