Snap Cap Vials are ideal containers for temporarily holding live insects These plastic snap cap vials are made of durable polystyrene plastic and feature a white snap-tight cap to keep your specimens secure. These clear plastic vials are practical for field and lab use. This vial is used in the Ecology Supplies aspirator. Extra tubes are convenient when collecting a large number or several different species with an aspirator.
A snap cap is a firearm accessory device shaped like a standard cartridge/shotshell but contains no functional components, namely the primer, propellant (gunpowder) and projectile (bullet or slug). It serves the same purpose as a dummy round, but different in that a dummy is usually modified from a real cartridge with its propellant and primer removed (but still has the projectile crimped to the casing), while a snap cap has a monolithic outer shell and is specifically designed to be a fake cartridge from the very beginning.
The term "snap cap" is a generic trademark of the fake cartridge originally introduced by American firearm accessory brand "A-Zoom", and is a word play on percussion cap. It is now used to refer to any accessory product made to perform similar function.[1]
A snap cap is used to ensure that dry-firing firearms of certain designs does not cause stress and impact damage to the firing pin and/or the barrel breech. Some snap caps contain a false primer that is either spring-buffered, made of rubber or soft polymer, or none at all. The springs or plastic will absorb the impact force from the firing pin during dry-firing, allowing the user to practice trigger pull or safely test the function of the firearm action without damaging its components.[citation needed]
Rimfire and a small number of centerfire firearms of older design should not be test-fired with the chamber empty, as this can lead to weakening or breakage of the firing pin and increased wear to other components in those firearms. In the instance of a rimfire firearm, dry firing can also cause deformation of the chamber edge due to the firing pin striking it without the cartridge rim in between. For this reason some shooters use a snap cap in an attempt to cushion the firearm's firing pin as it moves forward. Most commercial snap caps have a polymer/rubber false primer to receive the firing pin strikes, which is usually usable for up to 300 to 400 clicks. After that, due to the impact crater on the false primer becoming deepened from the repeated strikes, the firing pin does not touch and transfer its momentum, and the snap cap loses its cushioning effect. Some higher-end snap caps have a spring-dampened false primer that can last much longer, but are also more expensive to make.[citation needed]
Some snap caps are made of a soft aluminum coated with paint. Other snap caps are manufactured using traditional brass shell casings and injecting a polymer material,[2] while others are made from a solid piece of plastic, including via 3D printing.[citation needed]
Snap caps are used for general dry-firing practice. There is some debate as to if dry firing a handgun may cause damage to the firing pin in a modern firearm. Using a snap cap or dummy round eliminates any potential risk of doing so if the snap cap has a solid primer cup. Some snap caps are made without a primer cup, and thus do not address this potential concern.[citation needed]
Snap caps and action-proving dummy cartridges also work as a training tool to simulate firearm malfunctions, the same as a dud would. The shooter loads one or more snap caps into the firearm or magazine along with live rounds; when the trigger is pulled with a snap cap in the chamber, a failure to fire occurs. The shooter can then practice clearing the bad round, which generally requires manually cycling the slide of a semi-automatic pistol.[citation needed]
As with malfunction training, snap caps are loaded along with live rounds, so that when the trigger is pulled with a snap cap in the chamber, the firearm does not fire. Here, the intent is to observe whether the shooter maintained proper trigger control (that is, did not flinch). This is often referred to as a ball and dummy drill.[3][4]
This coarse bubble diffuser is very clog resistant. It uses a snap-on flexible diaphragm with built-in check valve. Handles flowrates up to 10 cfm @ 12" H2O loss. About 2" high x 3 5/32" diameter with a 3/8" MNPT and a 1/2" MNPT adapter included.
Each crystal-clear polystyrene vial in this set of 12 comes with a white polyethylene snap cap. These vials are perfect for field observation of small insects, soil samples, or aquatic invertebrates. The 40 dram vials hold 5 fluid ounces.
This HDPE plastic bottle features a pinched waist oval design with a 14mm Euro Oval snap-on dispensing cap. The snap-on cap is easily twisted to remove for refilling if need be. Ideal for purse or travel.
Crimp caps and snap neck caps have similar functions when applied to vials. However, crimp caps require the use of additional tools, namely a crimping tool that forms the cap around the lip of the glass vial. For small volumes of samples, a manual crimper can be used, but for laboratories with large numbers of samples, the use of automated crimpers is preferred.While snap neck caps are more efficient, they may be more prone to cracking and other damage or an improper seal that compromises sample storage.
This snap neck cap is paired with a Preslit PTFE/Silicone septum, made to provide adequate venting and prevent vacuum formation in the sample vial. This creates superior sample-draw reproducibility and eliminates coring from bottom draw-port needles. Laboratories can also benefit from the good resealing ability, making these septa recommended for multiple injections. The working temperature range is -40 C to 200 C. Waters recommends these septa for venting and accurate sample draw.

Not suitable for older screw-cap-only models of the Bullet Blender (BBX24W or BBX24BW) - for those models, or if you have a Bullet Blender Storm or Bullet Blender Gold and prefer the RINO screw-cap tubes, click here for bead kits in RINO screw-cap tubes.
Opaque black 5 mL snap cap MacroTubes. Non-sterile, packed in bags. DNase and RNase free. 200 tubes/pack. Compatible with standard centrifuges and rotors. List Price $44.50.
Opaque 5 mL macrotubes are much more convenient to use than 15 mL tubes when working with smaller volumes. Reduces plastic waste, saves storage space and shipping costs. Use of short 5 mL conical tube (54 mm) reduces chance of contamination from pipettor shaft compared to use of 15 mL tube (120 mm). Easily open and close snap cap with one hand. Syringe port present in snap cap.
Black 5 mL snap cap MacroTubes withstand force up to 25,000 x g (when properly cushioned in centrifuge rotor). 16 mm tube outer diameter (OD) is the same OD as standard 15 mL conical tubes, allowing centrifugation in centrifuge rotors designed for 15 mL tubes (cushion adapters for 15 mL tube rotor available for purchase).
Cap lock clips, custom workstation rack, freezer boxes, minicentrifuge to fit 5 mL snap cap centrifuge tubes and color tinted and transparent (sterile and non-sterile) 5 mL snap cap centrifuge tubes also available for purchase.
The invention concerns a wig or lace wig cap, to be worn by the user underneath a wig or lace wig. The cap is comprised of a plurality of panels using stretchable and breathable material, an elasticized banding and a plurality of sew on snap fasteners affixed to, said banding to form the Press and Go Wig and Lace Wig Snap Cap. Cooperating snaps are then affixed to a wig or lace wig around the entire circumference of the outer inside wig weft, concealing the application process, thereby producing a comfortable, airy and secure fit to the user. An additional banding is included, affixed with a plurality of snap fasteners designed to fit cooperating snaps of a wig or lace wig. Also included is a tension strap affixed with two cooperating snap fasteners designed to be used as an adjustment strap to the cap banding or separate banding. 041b061a72
